Recent Longevity News for the seven days ending 10/2/13.  You should consult your doctor if you are taking any medications.

Niacin, the fountain of youth - Science Daily, 9/30/13 - "Vitamin B3 -- also known as niacin -- and its metabolite nicotinamide in the worms' diet caused them to live for about one tenth longer than usual" - See niacin products at iHerb.

Diabetes increases risk of developing and dying from breast and colon cancer - Science Daily, 9/27/13 - "analyzed results from 20 trials that had taken place between 2007 and 2012, involving more than 1.9 million patients with breast or colon cancer, with or without diabetes ... patients with diabetes had a 23% increased risk of developing breast cancer and a 38% increased risk of dying from the disease compared to non-diabetic patients. Diabetic patients had a 26% increased risk of developing colon cancer and a 30% increased risk of dying from it compared to non-diabetic patients" - Note:  See my insulin and aging page for many more studies like this.

Researchers Tie Increased Throat Cancer Cases to HPV Infection - WebMD, 9/27/13 - "In a new study, investigators from Henry Ford Hospital in Detroit analyzed U.S. government data and found that cancers of the base of the tongue, tonsils, soft palate and pharynx among adults aged 45 and younger increased 60 percent between 1973 and 2009. Collectively, these cancers are called oropharyngeal cancer ... Of the 1,600 patients in the study group, 90 percent were aged 36 to 44 and 73 percent were white. Fifty percent to 65 percent of the patients had surgery to remove their tumors. Patients who had both surgery and radiation had the highest five-year survival rate" - Note:  That’s what they told me eight years ago when I had tonsil cancer that spread to the lymph nodes in the neck that became the size of a golf ball. I refused radiation anyway and just went with surgery. I’m still here without the permanent side effects such as lack of saliva. I’m never seen hard numbers on it but my guess would be that adding radiation doesn’t add that much to your odds. My theory was that radiation might kill some of the satellite cancer cells but at the same time it weakens your immunity which might also be needed to fight those cancer cells. I’ve gone through at least ten doctors due to Navy turnover during checkups. Toward the latter, the doctors said that they would have done what I did. Their attitude changed over the years.

Folic acid deficiency can affect the health of great, great grandchildren - Science Daily, 9/27/13 - "the scientists used mice in which a gene called Mtrr was specifically mutated. The gene is key to the normal progression of the folic acid cycle and, when mutated, it results in abnormal folic acid metabolism causing similar effects to dietary folic acid deficiency. The researchers found that when either the maternal grandmother or the maternal grandfather had this Mtrr mutation, their genetically normal grandchildren were at risk of a wide spectrum of developmental abnormalities. These developmental abnormalities were also seen in the fourth and fifth generations of mice"

15 Myths and Facts About Cellulite - ABC News, 90/27/13 - "eating a well-balanced, plant-heavy diet can reduce inflammation throughout your body and help you maintain a healthy weight ... Staying hydrated—both by drinking water and by eating plenty of foods with high water content—will also keep your connective tissue strong and supple, and may even help you lose weight. Aim to eat more cucumbers, radishes, tomatoes, and bell peppers, which (along with many other fruits and veggies) are all more than 90 percent water"

Wisconsin Ginseng (Panax quinquefolius) to Improve Cancer-Related Fatigue - Medscape, 9/27/13 - "cancer-related fatigue (CRF) ... A multisite, double-blind trial randomized fatigued cancer survivors to 2000mg of American ginseng vs a placebo for 8 weeks ... Multidimensional Fatigue Symptom Inventory–Short Form (MFSI-SF) ... A statistically significant difference was seen at 8 weeks with a change score of 20 (SD = 27) for the ginseng group and 10.3 (SD = 26.1) for the placebo group (P = .003). Greater benefit was reported in patients receiving active cancer treatment vs those who had completed treatment. Toxicities per self-report and CTCAE grading did not differ statistically significantly between arms" - See ginseng at Amazon.com.

Big Breakfast May Be Best for Diabetes Patients - WebMD, 9/26/13 - "randomly assigned 59 people with type 2 diabetes to either a big or small breakfast group ... after 13 weeks, blood sugar levels and blood pressure dropped dramatically in people who ate a big breakfast every day. Those who ate a big breakfast enjoyed blood sugar level reductions three times greater than those who ate a small breakfast, and blood pressure reductions that were four times greater ... About one-third of the people eating a big breakfast ended up cutting back on the daily diabetic medication they needed to take. By comparison, about 17 percent of the small breakfast group had to increase their medication prescriptions during the course of the trial ... Rabinovitz speculated that a big breakfast rich in protein causes suppression of ghrelin, which is known as the "hunger hormone."

Experts Confirm That Fruit and Vegetable Consumption Reduces Risk of Mortality - Science Daily, 9/26/13 - "sample analyzed includes 25,682 deaths (10,438 due to cancer and 5,125 due to cardiovascular disease) among the 451,151 participants studied over more than 13 years ... a combined fruit and vegetable consumption of more than 569 grams per day reduces the risk of mortality by 10% and delays the risk of mortality by 1.12 years compared to a consumption of less than 249 grams per day ... for every 200 gram increase in daily fruit and vegetable consumption, the risk falls by 6% ... A diet rich in fruit and vegetables reduces the risk of cardiovascular disease mortality by 15%" - Note: 569 grams is 20 ounces.

Common Diabetes Drugs May Carry Risk, Study Suggests - WebMD, 9/26/13 - "Both metformin (brand names include Glucophage and Fortamet) and sulfonylureas (glyburide and glipizide) are commonly prescribed as first-line therapies for patients and have been available since the 1950s ... Patients who took sulfonylureas only were 58 percent more likely to die from any cause than those who took metformin only ... Sulfonylureas work "by increasing insulin release from the beta cells in the pancreas," while metformin "acts by suppressing glucose production by the liver,""

Melatonin Helps Control Weight Gain as It Stimulates the Appearance of ‘beige Fat’ That Can Burn Calories Instead of Storing Them, Study Suggests - Science Daily, 9/25/13 - "chronic administration of melatonin sensitizes the thermogenic effect of exposure to cold, heightens the thermogenic effect of exercise and, therefore, constitutes excellent therapy against obesity. The fact is that one of the key differences between 'beige fat', which appears when administering melatonin, and 'white fat', is that 'beige fat' cell mitochondria express levels of UCP1 protein, responsible for burning calories and generating heat" - See melatonin at Amazon.com.  Supports previous studies:

  • Melatonin might help in controlling weight gain and preventing heart diseases associated to obesity - Science Daily, 4/28/11 - "melatonin -a natural hormone produced by the body- helps in controlling weight gain -even without reducing the intake of food-, improves blood lipid profile -as it reduces triglicerids-, increases HDL cholesterol and reduces LDL cholesterol ... analyzed in young Zucker diabetic obese rats the effects of melatonin on obesity, dyslipidemia and high blood pressure associated to obesity. Melatonin was found to be beneficial for young rats that had not still developed any methabolic or heart disease"

Commonly prescribed statin linked to memory impairment, study in rats suggests - Science Daily, 9/25/13 - "tested pravastatin and atorvostatin (two commonly prescribed statins) in rat learning and memory models ... Rats were treated daily with pravastatin (brand name -- pravachol) or atorvostatin (brand name -- Lipitor) for 18 days ... pravastatin tended to impair learning over the last few days of treatment although this effect was fully reversed once treatment ceased. However, in the novel object discrimination task, pravastatin impaired object recognition memory. While no effects were observed for atorvostatin in either task"

Statins Tied to Cataract Risk - NYTimes.com, 9/25/13 - "scientists retrospectively examined 13,626 statin users and 32,623 nonusers, ages 30 to 85, who were part of a military health care system. The average length of statin use was about two years ... compared with nonusers, those who took statins had a 9 to 27 percent increased risk for cataracts" - Note:  It conflicts with other studies:

  • Statins Prevent Cataracts, Study Suggests - Science Daily, 8/31/13 - "Statins lower the rate of cataract by 20 percent ... The risk of cataract was reduced by 50 percent when treatment was initiated in younger individuals (in their 40s) and the duration of therapy was longer (e.g. up to 14 years) ... The meta-analysis included 2,399,200 persons and 25,618 cataracts. The average duration of treatment was 54 months and average age was 61"

Nutrient Supplementation - Medscape, 9/25/13 - "men taking antioxidants had a statistically significant increase in both live birth rates and pregnancy rates. For those undergoing assisted reproduction, the odds ratio that antioxidant use would improve pregnancy rates was 4.18, with a 4.85-fold improvement in live birth rate also noted" - See Garden of Life, Radical Fruits Antioxidant Complex at Amazon.com and Garden of Life, Vitamin Code, 50 & Wiser Men at Amazon.com.

High Serum Calcium Linked to Developing Diabetes - Medscape, 9/24/13 - "High concentrations of serum calcium—but not necessarily calcium intake—are associated with an increased risk of developing type 2 diabetes, results from the Insulin Resistance Atherosclerosis Study (IRAS) show ... IRAS enrolled 863 nondiabetic subjects (age 40–69) at four centers ... the relationship between calcium concentration and incident diabetes was statistically significant but did not follow a linear relationship. Only subjects with the highest concentrations of calcium (>2.38 mmol/L) had a significantly increased risk of developing diabetes"

Long-term resveratrol treatment prevents ovariectomy-induced osteopenia in rats without hyperplastic effects on the uterus - Br J Nutr. 2013 Sep 30:1-11 - "In conclusion, Res treatment not only improves BMD and trabecular microarchitecture but also does not affect the uterus and Res might be a potential remedy for the treatment of postmenopausal osteoporosis" - See resveratrol products at Amazon.com.

Coenzyme Q10 supplementation reverses age-related impairments in spatial learning and lowers protein oxidation - Age (Dordr). 2013 Oct;35(5):1821-34 - "the current study assessed the effect of CoQ intake in older mice for which cognitive and psychomotor impairments were already evident. Separate groups of young (3.5 months) and relatively old mice (17.5 months) were fed a control diet or a diet supplemented with low (0.72 mg/g) or high (2.81 mg/g) concentrations of CoQ for 15 weeks. After 6 weeks, the mice were given tests for spatial learning (Morris water maze), spontaneous locomotor activity, motor coordination, and startle reflex. Age-related impairments in cognitive and psychomotor functions were evident in the 17.5-month-old mice fed the control diet, and the low-CoQ diet failed to affect any aspect of the impaired performance. However, in the Morris water maze test, old mice on the high-CoQ diet swam to the safe platform with greater efficiency than the mice on the control diet. The old mice supplemented with the high-CoQ diet did not show improvement when spatial performance was measured using probe trials and failed to show improvement in other tests of behavioral performance. Protein oxidative damage was decreased in the mitochondria from the heart, liver, and skeletal muscle of the high-CoQ-supplemented mice and, to some extent, in the brain mitochondria. Contrasting with the deleterious effect of long-term CoQ supplementation initiated during young adulthood previously published, this study suggests that CoQ improves spatial learning and attenuates oxidative damage when administered in relatively high doses and delayed until early senescence, after age-related declines have occurred. Thus, in individuals with age-associated symptoms of cognitive decline, high-CoQ intake may be beneficial" - See ubiquinol products at Amazon.com.

Oral Caffeine During Voluntary Exercise Markedly Inhibits Skin Carcinogenesis and Decreases Inflammatory Cytokines in UVB-Treated Mice - Nutr Cancer. 2013 Sep 26 - "Ultraviolet B (UVB)-pretreated SKH-1 mice were treated with water, caffeine (0.1 mg/ml), voluntary running wheel exercise (RW) or caffeine together with RW for 14 wk. Treatment of the mice with caffeine, RW, or caffeine plus RW decreased skin tumors per mouse by 27%, 35%, and 62%, respectively, and the tumor volume per mouse was decreased by 61%, 70%, and 85%, respectively"

High Dose Atorvastatin Reduces Periodontal Inflammation: A Novel Pleiotropic Effect of Statins - J Am Coll Cardiol. 2013 Sep 23 - "Eighty-three adults with risk factors or with established atherosclerosis, who were not taking high-dose statins, were randomized to atorvastatin 80 mg vs. 10mg in a multicenter, double-blind trial to evaluate the impact of atorvastatin on arterial inflammation ... After 12 weeks, there was a significant reduction in periodontal inflammation in patients randomized to atorvastatin 80 vs. 10 mg (ΔTBR mean [95 CI], 80mg vs. 10mg group = -0.43 [-0.83, -0.02], p=0.04). Between-group differences were greater in patients with higher periodontal inflammation at baseline (-0.74 [-1.29, -0.19], p=0.01) and in patients with severe bone loss at baseline (-0.61 [-1.16, -0.054], p=0.03). Furthermore, the changes in periodontal inflammation correlated with changes in carotid inflammation"

Effects of the DASH diet on blood pressure in patients with and without metabolic syndrome: results from the DASH trial - J Hum Hypertens. 2013 Sep 26 - "This paper is a subgroup analysis of the DASH trial, in which we examined the effect of study diets on BP in participants with and without MS ... participants were randomized to receive a control diet, a diet rich in fruits and vegetables, or the DASH diet ... In the MS subgroup, the DASH diet compared with the control diet reduced systolic BP by 4.9 mm Hg (P=0.006) and diastolic BP by 1.9 mm Hg (P=0.15). In the Non-MS subgroup, corresponding net BP reductions were 5.2 mm Hg (P<0.001) and 2.9 mm Hg (P<0.001), respectively"

Maternal fatty acids in pregnancy, FADS polymorphisms, and child intelligence quotient at 8 y of age - Am J Clin Nutr. 2013 Sep 25 - "These results support the positive role of maternal arachidonic acid and DHA on fetal neural development although the effects on child IQ by 8 y of age were small (0.1 SD) with other factors contributing more substantially. The endogenous synthesis of these FAs by FADS genes, especially FADS2, may also be important" - See Jarrow Max DHA at Amazon.com.

Is Dairy Intake Associated to Breast Cancer? A Case Control Study of Iranian Women - Nutr Cancer. 2013 Sep 25 - "100 cases and 175 controls ... Dietary data were assessed using a validated food frequency questionnaire ... We observed that higher consumption of total dairy intake was accompanied with reduced breast cancer risk [odds ratio (OR) = 0.14, 95% CI = 0.04-0.38]. A similar inverse association was also observed for higher intakes of low-fat and fermented dairy products (P for trend <0.05). Lower intake of high-fat dairy was associated with reduced odds of breast cancer, and no significant association was found between nonfermented dairy and breast cancer risk. Our study demonstrates the protective effects of high intakes of total dairy, low-fat and fermented dairy, as well as low intakes of high-fat dairy products against breast cancer risk and shows no association with nonfermented dairy" - Note:  Did I read that right, '0.14' or an 86% reduction in risk?  See my yogurt recipe at the top of my yogurt page.

Vitamin K status and cognitive function in healthy older adults - Neurobiol Aging. 2013 Dec;34(12):2777-83 - "Using data from the Québec Longitudinal Study on Nutrition and Successful Aging (NuAge), a cross-sectional analysis was conducted to examine the associations between vitamin K status, measured as serum phylloquinone concentrations, and performance in verbal and non-verbal episodic memory, executive functions, and speed of processing. The sample included 320 men and women aged 70 to 85 years who were free of cognitive impairment. After adjustment for covariates, higher serum phylloquinone concentration (log-transformed) was associated with better verbal episodic memory performances (F = 2.43, p = 0.048); specifically with the scores (Z-transformed) on the second (β = 0.47; 95% confidence interval [CI] = 0.13-0.82), third (β = 0.41; 95% CI = 0.06-0.75), and 20-minute delayed (β = 0.47; 95% CI = 0.12-0.82) free recall trials of the RL/RI-16 Free and Cued Recall Task" - See vitamin K products at iHerb.

Long-Chain Omega-3 Polyunsaturated Fatty Acid Intake and Risk of Colorectal Cancer Nutr Cancer. 2013 Sep 20 - "A total of 68,109 Washington residents aged 50-76 completed a questionnaire between 2000-2002 and were followed for CRC through 2008 (n = 488). Persons using fish oil supplements on 4+ days/wk for 3+ yr experienced 49% lower CRC risk than nonusers (hazard ratio = 0.51, 95% CI = 0.26-1.00; P trend = 0.06). The association between fish oil use and decreased CRC risk was primarily observed for men (P interaction = 0.02; P trend men = 0.02; P trend women = 0.88) and for colon cancer (P difference = 0.05; P trend colon = 0.03; P trend rectum = 0.87). Although dark fish and total EPA + DHA intake were not associated with CRC risk overall, these associations varied by genetic risk (P interaction = 0.009 and 0.02, respectively), with inverse associations observed among low-moderate genetic risk groups and positive associations observed among high risk groups" - See Mega Twin EPA at Amazon.com and Jarrow Max DHA at Amazon.com.

Serum Calcium Concentration and Prostate Cancer Risk: A Multicenter Study - Nutr Cancer. 2013 Sep 20 - "This study sought to further evaluate the possible effects of serum calcium level on prostate cancer (PC) risk, with considering the age, body mass index (BMI), and sex steroid hormones. Using data from a prospective multicenter study, serum calcium concentration, as well as thorough demographic and medical characteristics, were determined in 194 cases with newly diagnosed, clinicopathologically confirmed PC and 317 controls, without any malignant disease, admitted to the same network of hospitals ... An increase of 1 mg/dl in serum calcium level was associated with a significant decrease in PC risk (OR = 0.52; 95% CI = 0.34-0.76). Our findings reveal the inverse association between serum total and ionized concentrations and PC risk, which supports the hypothesis that calcium may protect against PC" - Note:  Conflicts with some previous studies.

The cells continued to proliferate at 4 months. EGb761 also significantly improved learning and memory in rats with vascular dementia" - See Ginkgo biloba at Amazon.com.
  • Diabetes Drug May Protect the Brain - WebMD, 7/15/13 - "Metformin makes muscle tissue more receptive to insulin, a hormone necessary for sugar (glucose) to get into the body's cells and tissues to provide fuel. It also decreases the amount of glucose made in the liver. Sulfonylureas stimulate the production of insulin. TZDs make muscle and fat tissue more receptive to insulin, and they decrease the amount of glucose made in the liver ... Compared to people taking sulfonylureas, those on metformin had a 20 percent decreased risk of developing dementia, according to the study. There was no difference in dementia risk for those on TZDs or insulin compared to those on sulfonylureas ... one theory stemming from animal research is that metformin may play a role in the development of new brain cells (neurogenesis). It has also been linked to reduced inflammation ... A drug like metformin, [which is] an insulin sensitizer in the body, may also be an insulin sensitizer in the brain" - See metformin at The Antiaging Store.

  • Long-term Ginsenoside Rg1 Supplementation Improves Age-Related Cognitive Decline by Promoting Synaptic Plasticity Associated Protein Expression in C57BL/6J Mice - J Gerontol A Biol Sci Med Sci. 2013 Jul 5 - "In aging individuals, age-related cognitive decline is the most common cause of memory impairment. Among the remedies, ginsenoside Rg1, a major active component of ginseng, is often recommended for its antiaging effects ... This study employed a scheme of Rg1 supplementation for female C57BL/6J mice, which started at the age of 12 months and ended at 24 months, to investigate the effects of Rg1 supplementation on the cognitive performance. We found that Rg1 supplementation improved the performance of aged mice in behavior test and significantly upregulated the expression of synaptic plasticity-associated proteins in hippocampus, including synaptophysin, N-methyl-d-aspartate receptor subunit 1, postsynaptic density-95, and calcium/calmodulin-dependent protein kinase II alpha, via promoting mammalian target of rapamycin pathway activation. These data provide further support for Rg1 treatment of cognitive degeneration during aging" - See ginseng at Amazon.com.

  • Preventing Alzheimer's disease-related gray matter atrophy by B-vitamin treatment - Proc Natl Acad Sci U S A. 2013 May 20 - "Is it possible to prevent atrophy of key brain regions related to cognitive decline and Alzheimer's disease (AD)? One approach is to modify nongenetic risk factors, for instance by lowering elevated plasma homocysteine using B vitamins. In an initial, randomized controlled study on elderly subjects with increased dementia risk (mild cognitive impairment according to 2004 Petersen criteria), we showed that high-dose B-vitamin treatment (folic acid 0.8 mg, vitamin B6 20 mg, vitamin B12 0.5 mg) slowed shrinkage of the whole brain volume over 2 y. Here, we go further by demonstrating that B-vitamin treatment reduces, by as much as seven fold, the cerebral atrophy in those gray matter (GM) regions specifically vulnerable to the AD process, including the medial temporal lobe ... B vitamins lower homocysteine, which directly leads to a decrease in GM atrophy, thereby slowing cognitive decline" - See folic acid products at Amazon.com and vitamin B12 at Amazon.com.

Early studies showed that the extract was superior to placebo in improving symptoms of dementia, and this has been confirmed by more recent research. The GINDEM-NP, GOTADAY and GOT-IT! studies showed that 240 mg/day EGb 761® improved cognitive function, neuropsychiatric symptoms, activities of daily living, and quality of life in patients with mild to moderate dementia compared with placebo, with results reproducible in independent trials. The strength of the effect in terms of improvements in neurosensory symptoms associated with old age and dementia was strong enough to be detected by caregivers and independent clinicians. A combination of 240 mg/day EGb 761® and 10 mg/day (initially 5 mg/day) donepezil was also more effective than either drug alone. Regarding the improvement of neuropsychiatric symptoms, a cross-comparison of studies with different antidementia agents suggests that EGb 761® is at least as effective as memantine, galantamine, and donepezil. Safety data revealed no important safety concerns with EGb 761®" - See Ginkgo biloba at Amazon.com.

  • Body iron is associated with cognitive executive planning function in college women - Br J Nutr. 2012 Jun 7:1-8 - "The aim of the present study was to examine the relationship between body Fe, in the absence of Fe-deficiency anaemia, and neuropsychological function in young college women. Healthy, non-anaemic undergraduate women (n 42) provided a blood sample and completed a standardised cognitive test battery consisting of one manual (Tower of London (TOL), a measure of central executive function) and five computerised (Bakan vigilance task, mental rotation, simple reaction time, immediate word recall and two-finger tapping) tasks. Women's body Fe ranged from - 4.2 to 8.1 mg/kg. General linear model ANOVA revealed a significant effect of body Fe on TOL planning time (P = 0.002). Spearman's correlation coefficients showed a significant inverse relationship between body Fe and TOL planning time for move categories 4 (r - 0.39, P = 0.01) and 5 (r - 0.47, P = 0.002). Performance on the computerised cognitive tasks was not affected by body Fe level.

  • Does Lithium Prevent Alzheimer's Disease? - Drugs Aging. 2012 Apr 14 - "Lithium salts have a well-established role in the treatment of major affective disorders. More recently, experimental and clinical studies have provided evidence that lithium may also exert neuroprotective effects. In animal and cell culture models, lithium has been shown to increase neuronal viability through a combination of mechanisms that includes the inhibition of apoptosis, regulation of autophagy, increased mitochondrial function, and synthesis of neurotrophic factors. In humans, lithium treatment has been associated with humoral and structural evidence of neuroprotection, such as increased expression of anti-apoptotic genes, inhibition of cellular oxidative stress, synthesis of brain-derived neurotrophic factor (BDNF), cortical thickening, increased grey matter density, and hippocampal enlargement ... A recent placebo-controlled clinical trial in patients with amnestic mild cognitive impairment (MCI) showed that long-term lithium treatment may actually slow the progression of cognitive and functional deficits, and also attenuate Tau hyperphosphorylation in the MCI-AD continuum" - See lithium supplement at Amazon.com.
  • "Metabolic syndrome" in the brain: Deficiency in omega-3-fatty acid exacerbates dysfunctions in insulin receptor signaling and cognition - J Physiol. 2012 Apr 2 - "high-dietary fructose consumption leads to increase in insulin resistance index, insulin and triglyceride levels, which characterize MetS. Rats fed on an n-3 deficient diet showed memory deficits in Barnes Maze, which were further exacerbated by fructose intake. In turn, n-3 deficient diet and fructose interventions disrupted insulin receptor signaling in hippocampus as evidenced by a decrease in phosphorylation of insulin receptor and its downstream effector Akt. We found that high fructose consumption with n-3 deficient diet disrupts membrane homeostasis as evidenced by an increase in the ratio of n-6/n-3 fatty acids and levels of 4-hydroxynonenal (4-HNE), a marker of lipid peroxidation. Disturbances in brain energy metabolism due to n-3 deficiency and fructose treatments were evidenced by a significant decrease in AMPK phosphorylation and its upstream modulator LKB1 as well as a decrease in Sir2 levels. The decrease in phosphorylation of CREB, synapsin I and synaptophysin (SYP) levels by n-3 deficiency and fructose shows the impact of metabolic dysfunction on synaptic plasticity. All parameters of metabolic dysfunction related to the fructose treatment were ameliorated by the presence of dietary n-3 fatty acid. Results showed that dietary n-3 fatty acid deficiency elevates the vulnerability to metabolic dysfunction and impaired cognitive functions by modulating insulin receptor signaling and synaptic plasticity" - See Mega Twin EPA at Amazon.com and Jarrow Max DHA at Amazon.com.

  • Boosting mental performance with fish oil? - Science Daily, 10/21/11 - "overall, taking either of two different types of fish oil supplement for three months had no consistent impact on mental function in 18 -- 35-year-olds, however they did find evidence of reduced mental fatigue and faster reaction times. Contrary to popular belief, these results suggest that taking omega-3 or fish oil supplements may not have an immediate or measureable impact on mental performance in healthy young adults, possibly due to the fact that this population is already performing at its mental peak or that higher doses or longer than 12 weeks supplementation are required ... Interestingly, in the second of these studies it was found that taking DHA-rich fish oil over the same time period did increase blood flow to active areas of the brain during performance of similar mental tasks. The researchers claim these findings could have implications for mental function later on in life, as evidence suggests regularly eating oily fish or taking omega-3 supplements may prevent cognitive decline and dementia, and increased blood flow to the brain may be a mechanism by which this occurs" - See Mega Twin EPA at Amazon.com and Jarrow Max DHA at Amazon.com.

Methylmalonate levels were associated with poorer episodic memory and perceptual speed, and cystathionine and 2-methylcitrate with poorer episodic and semantic memory. Homocysteine concentrations were associated with decreased total brain volume. The homocysteine-global cognition effect was modified and no longer statistically significant with adjustment for white matter volume or cerebral infarcts. The methylmalonate-global cognition effect was modified and no longer significant with adjustment for total brain volume ... Methylmalonate, a specific marker of B12 deficiency, may affect cognition by reducing total brain volume whereas the effect of homocysteine (nonspecific to vitamin B12 deficiency) on cognitive performance may be mediated through increased white matter hyperintensity and cerebral infarcts.

Physiological and cognitive assessments, questionnaires and fatty acid composition of erythrocytes were obtained at baseline and 6 months (completers: n 40; EPA n 13, DHA n 16, LA n 11). Compared with the LA group, GDS scores improved in the EPA (P = 0.04) and DHA (P = 0.01) groups and verbal fluency (Initial Letter Fluency) in the DHA group (P = 0.04). Improved GDS scores were correlated with increased DHA plus EPA (r 0.39, P = 0.02). Improved self-reported physical health was associated with increased DHA. There were no treatment effects on other cognitive or QOL parameters. Increased intakes of DHA and EPA benefited mental health in older people with MCI. Increasing n-3 PUFA intakes may reduce depressive symptoms and the risk of progressing to dementia. This needs to be investigated in larger, depressed samples with MCI" - See Mega Twin EPA at Amazon.com and Jarrow Max DHA at Amazon.com.
  • Aerobic exercise may reduce the risk of dementia, researchers say - Science Daily, 9/7/11 - "Researchers examined the role of aerobic exercise in preserving cognitive abilities and concluded that it should not be overlooked as an important therapy against dementia ... Examples include walking, gym workouts and activities at home such as shoveling snow or raking leaves ... We culled through all the scientific literature we could find on the subject of exercise and cognition, including animal studies and observational studies, reviewing over 1,600 papers, with 130 bearing directly on this issue ... brain imaging studies have consistently revealed objective evidence of favorable effects of exercise on human brain integrity"
  • Fish oil's impact on cognition and brain structure identified in new study - Science Daily, 8/17/11 - "Researchers at Rhode Island Hospital's Alzheimer's Disease and Memory Disorders Center have found positive associations between fish oil supplements and cognitive functioning as well as differences in brain structure between users and non-users of fish oil supplements ... compared to non-users, use of fish oil supplements was associated with better cognitive functioning during the study. However, this association was significant only in those individuals who had a normal baseline cognitive function and in individuals who tested negative for a genetic risk factor for Alzheimer's Disease known as APOE4. This is consistent with previous research ... The unique finding, however, is that there was a clear association between fish oil supplements and brain volume ... In other words, fish oil use was associated with less brain shrinkage in patients taking these supplements during the ADNI study compared to those who didn't report using them" - See Mega Twin EPA at Amazon.com and Jarrow Max DHA at Amazon.com.
  • Exercise has numerous beneficial effects on brain health and cognition, review suggests - Science Daily, 7/25/11 - "In a new review article highlighting the results of more than a hundred recent human and animal studies on this topic, Michelle W. Voss, of the University of Illinois at Urbana-Champaign, and her colleagues show that both aerobic exercise and strength training play a vital role in maintaining brain and cognitive health throughout life ... The review suggests that aerobic exercise is important for getting a head start during childhood on cognitive abilities that are important throughout life. For example, physical inactivity is associated with poorer academic performance and results on standard neuropsychological tests, while exercise programs appear to improve memory, attention, and decision-making. These effects also extend to young and elderly adults, with solid evidence for aerobic training benefiting executive functions, including multi-tasking, planning, and inhibition, and increasing the volume of brain structures important for memory"
  • French adults' cognitive performance after daily supplementation with antioxidant vitamins and minerals at nutritional doses: a post hoc analysis of the Supplementation in Vitamins and Mineral Antioxidants (SU.VI.MAX) trial - Am J Clin Nutr. 2011 Jul 20 - "This study included 4447 French participants aged 45-60 y who were enrolled in the SU.VI.MAX study (1994-2002), which was a double-blind, placebo-controlled, randomized trial. From 1994 to 2002, participants received daily vitamin C (120 mg), β-carotene (6 mg), vitamin E (30 mg), selenium (100 μg), and zinc (20 mg) in combination or as a placebo. In 2007-2009, the cognitive performance of participants was assessed with 4 neuropsychological tests (6 tasks). Principal components analysis (PCA) was performed to identify cognitive-function summary scores. Associations between antioxidant supplementation and cognitive functions, in the full sample and by subgroups, were estimated through ANOVA and expressed as mean differences and 95% CIs. Subgroup analyses were performed according to baseline characteristics ... Subjects receiving active antioxidant supplementation had better episodic memory scores (mean difference: 0.61; 95% CI: 0.02, 1.20). PCA indicated 2 factors that were interpreted as showing verbal memory and executive functioning. Verbal memory was improved by antioxidant supplementation only in subjects who were nonsmokers or who had low serum vitamin C concentrations at baseline"
  • Exercise Sharpens Older Minds - WebMD, 7/20/11 - "Two new studies add to growing evidence that physical activity helps to keep older people's brains sharp ... women in the highest two-fifths of physical activity had substantially lower rates of cognitive decline than women in the lowest exercise bracket ... In the second study, researchers used a more objective measure of energy expended during physical activity, employing the so-called doubly labeled water technique to determine how much water a person loses ... Over the next two to five years, those in the highest third of energy expenditure were substantially less likely to develop clinical cognitive impairment than those in the lowest third ... About 2% of people in the highest third suffered declines in cognitive function, compared with 5% in the middle third and 17% in the lowest third"
  • Habitual sugar intake and cognitive function among middle-aged and older Puerto Ricans without diabetes - Br J Nutr. 2011 Jun 1:1-10 - "Intake of added sugars, mainly fructose and sucrose, has been associated with risk factors for cognitive impairment, such as obesity, the metabolic syndrome and type 2 diabetes. The objective of this analysis was to examine whether habitual intakes of total sugars, added sugars, sugar-sweetened beverages or sweetened solid foods are associated with cognitive function. The present study included 737 participants without diabetes, aged 45-75 years, from the Boston Puerto Rican Health Study, 2004-9. Cognitive function was measured with a battery of seven tests: Mini-Mental State Examination (MMSE), word list learning, digit span, clock drawing, figure copying, and Stroop and verbal fluency tests. Usual dietary intake was assessed with a validated FFQ. Greater intakes of total sugars, added sugars and sugar-sweetened beverages, but not of sugar-sweetened solid foods, were significantly associated with lower MMSE score, after adjusting for covariates. Adjusted OR for cognitive impairment (MMSE score < 24) were 2.23 (95 % CI 1.24, 3.99) for total sugars and 2.28 (95 % CI 1.26, 4.14) for added sugars, comparing the highest with lowest intake quintiles. Greater intake of total sugars was also significantly associated with lower word list learning score. In conclusion, higher sugar intake appears to be associated with lower cognitive function, but longitudinal studies are needed to clarify the direction of causality"
  • Nutritional Supplement Boosts Cognition in Healthy Women - Medscape, 6/21/11 - "Citicoline, a naturally occurring substance found in the brain and liver and marketed as a nutritional supplement, enhanced aspects of cognition in healthy women and may have a role in mitigating the cognitive decline associated with normal aging ... It may also improve the attention deficits associated with psychiatric disorders ... The women were divided into 3 groups of 20 and randomly assigned to receive a daily oral citicoline dose of 250 mg (low dose) or 500 mg (high dose) or placebo for 28 days ... participants who received low- or high-dose citicoline showed improved attention, demonstrating fewer commission and omission errors on the CPT-II compared with the placebo group" - See citicholine at Amazon.com.
  • Mystery ingredient in coffee boosts protection against Alzheimer's disease - Science Daily, 6/21/11 - "A yet unidentified component of coffee interacts with the beverage's caffeine, which could be a surprising reason why daily coffee intake protects against Alzheimer's disease. A new Alzheimer's mouse study by researchers at the University of South Florida found that this interaction boosts blood levels of a critical growth factor that seems to fight off the Alzheimer's disease process ... The new study does not diminish the importance of caffeine to protect against Alzheimer's. Rather it shows that caffeinated coffee induces an increase in blood levels of a growth factor called GCSF (granulocyte colony stimulating factor). GCSF is a substance greatly decreased in patients with Alzheimer's disease and demonstrated to improve memory in Alzheimer's mice ... The boost in GCSF levels is important, because the researchers also reported that long-term treatment with coffee (but not decaffeinated coffee) enhances memory in Alzheimer's mice. Higher blood GCSF levels due to coffee intake were associated with better memory ... First, GCSF recruits stem cells from bone marrow to enter the brain and remove the harmful beta-amyloid protein that initiates the disease. GCSF also creates new connections between brain cells and increases the birth of new neurons in the brain ... An increasing body of scientific literature indicates that moderate consumption of coffee decreases the risk of several diseases of aging, including Parkinson's disease, Type II diabetes and stroke"
  • Fatty Acids and Cognitive Decline in Women - Medscape, 6/13/11 - "In this cohort of older women, greater MUFA intake was associated with less cognitive decline over a 3-year period. Previous studies generally but not invariably support this association. One previous prospective study found greater dietary MUFA intake to be associated with less cognitive decline,[10] a second found a trend in the same direction,[9] a third found a trend in the same direction in restricted analyses,[6] and three others were null.[7,8,11] None of the null studies had multiple measures of diet; one assessed diet using a measure of fatty acid composition of erythrocyte membranes,[7] but that study assessed cognitive decline exclusively using the Mini-Mental State Examination, which is probably not as sensitive as the neuropsychological test battery used in this study ... MUFA is thought to be one of the major protective components of the traditional Mediterranean diet, in which it is derived primarily from olive oil (median 46 g/d).[10] Two recent prospective studies of the Mediterranean diet have found greater adherence to be associated with less cognitive decline and lower incidence of Alzheimer's disease (AD).[31,32] One of these studies found an effect of the Mediterranean diet on an individual cognitive domain, namely memory.[31] This finding is consistent with the observed protective effect of MUFA on memory in the WHI CCW. In addition, the current study found an association between MUFA and less decline in visual–spatial abilities (copying and matching), a finding not previously made to the knowledge of the authors of the current study. Decline in visuospatial function has been associated with driving errors in older adults[33] and has also been suggested as a potential predictor (along with amnestic impairment) of transition from mild cognitive impairment to AD ... Several pathways may explain the apparent relationship between MUFA intake and cognitive function. MUFA and MUFA derivatives have antiinflammatory effects in vivo,[35,36] which may be important because chronic inflammation appears to be a precursor of symptomatic AD.[37–39] Oxidative stress has also been demonstrated in patients with mild cognitive impairment and AD,[40] and derivatives from MUFA, including low-molecular-weight phenols, have been found to have antioxidant effects.[41] MUFA may also exert their potentially beneficial effects on cognition indirectly by decreasing cardiovascular risk by reducing macrophage uptake of plasma oxidized low-density lipoprotein, apolipoprotein B, and f triglycerides" - Click here for my olive oil mayonnaise recipe.

  • Musical experience offsets some aging effects: Older musicians excel in memory and hearing speech in noise compared to non-musicians - Science Daily, 5/11/11 - "when compared to their non-musician counterparts -- musicians 45- to 65-years-old excel in auditory memory and the ability to hear speech in noisy environments ... Difficulty hearing speech in noise is among the most common complaints of older adults, but age-related hearing loss only partially accounts for this impediment that can lead to social isolation and depression ... It's well known that adults with virtually the same hearing profile can differ dramatically in their ability to hear speech in noise ... The musicians -- who began playing an instrument at age 9 or earlier and consistently played an instrument throughout their lives -- bested the non-musician group in all but visual working memory, where both groups showed nearly identical ability ... Music training "fine-tunes" the nervous system"
  • Green tea extract shows memory boosting activity: Study - Nutra USA, 5/4/11 - "A combination of a green tea extract with L-theanine was associated with improvements in immediate and delayed recall, and general memory, according to findings published in the Journal of Medicinal Foods ...

  • Moderate exercise dramatically improves brain blood flow in elderly women - Science Daily, 4/12/11 - "it's never too late for women to reap the benefits of moderate aerobic exercise. In a 3-month study of 16 women age 60 and older, brisk walking for 30-50 minutes three or four times per week improved blood flow through to the brain as much as 15% ... At study's end, the team measured blood flow in the women's carotid arteries again and found that cerebral blood flow increased an average of 15% and 11% in the women's left and right internal carotid arteries, respectively. The women's VO2 max increased roughly 13%, their blood pressure dropped an average of 4%, and their heart rates decreased approximately 5% ... A steady, healthy flow of blood to the brain achieves two things. First, the blood brings oxygen, glucose and other nutrients to the brain, which are vital for the brain's health. Second, the blood washes away brain metabolic wastes such as amyloid-beta protein released into the brain's blood vessels. Amyloid-beta protein has been implicated in the development of Alzheimer's disease"
  • Older age memory loss tied to stress hormone receptor in brain - Science Daily, 4/6/11 - "one receptor was activated by low levels of cortisol, which helped memory. However, once levels of this stress hormone were too high they spilled over onto a second receptor. This activates brain processes that contribute to memory impairment ... high levels of the stress hormone in aged mice made them less able to remember how to navigate a maze. The memory recall problem was reversed when the receptor linked to poor memory was blocked ... lowering the levels of these stress hormones will prevent them from activating a receptor in the brain that is bad for memory ... The researchers are currently investigating a new chemical compound which blocks an enzyme -- 11beta-HSD1 -- that is involved in producing stress hormones within cells"
  • Exercise helps overweight children think better, do better in math - Science Daily, 2/10/11 - "Regular exercise improves the ability of overweight, previously inactive children to think, plan and even do math ... MRIs showed those who exercised experienced increased brain activity in the prefrontal cortex -- an area associated with complex thinking, decision making and correct social behavior -- and decreased activity in an area of the brain that sits behind it. The shift forward appears consistent with more rapidly developing cognitive skills ... And the more they exercised, the better the result. Intelligence scores increased an average 3.8 points in those exercising 40 minutes per day after school for three months with a smaller benefit in those exercising 20 minutes daily ... Animal studies have shown that aerobic activity increases growth factors so the brain gets more blood vessels, more neurons and more connections between neurons. Studies in older adults have shown exercise benefits the brain and Davis's study extends the science to children and their ability to learn in school"
  • Antioxidant effect of astaxanthin on phospholipid peroxidation in human erythrocytes - Br J Nutr. 2011 Jan 31:1-9 - "Phospholipid hydroperoxides (PLOOH) accumulate abnormally in the erythrocytes of dementia patients, and dietary xanthophylls (polar carotenoids such as astaxanthin) are hypothesised to prevent the accumulation ... After 12 weeks of treatment, erythrocyte astaxanthin concentrations were higher in both the 6 and 12 mg astaxanthin groups than in the placebo group. In contrast, erythrocyte PLOOH concentrations were lower in the astaxanthin groups than in the placebo group. In the plasma, somewhat lower PLOOH levels were found after astaxanthin treatment. These results suggest that astaxanthin supplementation results in improved erythrocyte antioxidant status and decreased PLOOH levels, which may contribute to the prevention of dementia" - See astaxanthin products at iHerb.
  • Exercise May Slow Age-Related Memory Loss - Science Daily, 1/31/11 - "A new study suggests moderate aerobic exercise may slow or even reverse age-related memory loss in older adults by increasing the size of the hippocampus ... one year of moderate aerobic exercise, like walking, in a group of older adults increased the volume of hippocampus by 2%, which effectively reversed the age-associated shrinkage by one to two years ... Brain scans taken at the start of the study and again one year later showed that the right and left sides of the hippocampus increased by 2.12% and 1.97%, respectively, in the aerobic exercise group ... these regions decreased in volume in the comparison group by 1.40% and 1.43%, respectively"
  • Adherence to a Mediterranean-type dietary pattern and cognitive decline in a community population - Am J Clin Nutr. 2010 Dec 22 - "investigated whether adherence to a Mediterranean dietary pattern or to the Healthy Eating Index-2005 (HEI-2005) is associated with cognitive change in older adults ... For both scoring systems, higher scores connote greater adherence ... Mean (+/-SD) scores for participants were 28.2 +/- 0.1 for the MedDiet and 61.2 +/- 9.6 for the HEI-2005. White participants had higher energy-adjusted MedDiet scores but lower HEI-2005 scores than did black participants. Higher MedDiet scores were associated with slower rates of cognitive decline (β = +0.0014 per 1-point increase, SEE = 0.0004, P = 0.0004) after adjustment for age, sex, race, education, participation in cognitive activities, and energy. No such associations were observed for HEI-2005 scores"

  • DHA May Prevent Age-Related Dementia - J Nutr. 2010 Feb 24 - "DHA is pleiotropic, acting at multiple steps to reduce the production of the beta-amyloid peptide, widely believed to initiate AD. DHA moderates some of the kinases that hyperphosphorylate the tau-protein, a component of the neurofibrillary tangle. DHA may help suppress insulin/neurotrophic factor signaling deficits, neuroinflammation, and oxidative damage that contribute to synaptic loss and neuronal dysfunction in dementia. Finally, DHA increases brain levels of neuroprotective brain-derived neurotrophic factor and reduces the (n-6) fatty acid arachidonate and its prostaglandin metabolites that have been implicated in promoting AD. Clinical trials suggest that DHA or fish oil alone can slow early stages of progression, but these effects may be apolipoprotein E genotype specific, and larger trials with very early stages are required to prove efficacy. We advocate early intervention in a prodromal period with nutrigenomically defined subjects with an appropriately designed nutritional supplement, including DHA and antioxidants" - See Jarrow Max DHA at Amazon.com.

  • The Ginkgo biloba extract EGb 761((R)) and its main constituent flavonoids and ginkgolides increase extracellular dopamine levels in the rat prefrontal cortex - Br J Pharmacol. 2010 Jan 25 - "A single oral dose of EGb 761 (100 mg.kg(-1)) had no effect on monoamine levels. However, following chronic (100 mg.kg(-1)/14 days/once daily) treatment, the same dose significantly increased extracellular dopamine and noradrenaline levels, while 5-HT levels were unaffected. Chronic treatment with EGb 761 showed dose-dependent increases in frontocortical dopamine levels and, to a lesser extent, in the striatum. The extracellular levels of HVA and DOPAC were not affected by either acute or repeated doses. Treatment with the main constituents of EGb 761 revealed that the increase in dopamine levels was mostly caused by the flavonol glycosides and ginkgolide fractions, whereas bilobalide treatment was without effect. Conclusions and implications: The present results demonstrate that chronic but not acute treatment with EGb 761 increased dopaminergic transmission in the PFC. This finding may be one of the mechanisms underlying the reported effects of G. biloba in improving cognitive function" - See Ginkgo biloba at Amazon.com.

  • A High-Salt Diet Further Impairs Age-Associated Declines in Cognitive, Behavioral, and Cardiovascular Functions in Male Fischer Brown Norway Rats - J Nutr. 2013 Jul 17 - "we tested the effect of high salt (HS) on anxiety, learning-memory function, and blood pressure (BP) in male Fischer brown Norway (FBN) rats. Adult (A; 2 mo) and old (O; 20 mo) male rats were fed normal-salt (NS; 0.4% NaCl) or HS (8% NaCl) diets for 4 wk after being implanted with telemeter probes for conscious BP measurement. Thereafter, tests to assess anxiety-like behavior and learning-memory were conducted. The rats were then killed, and samples of plasma, urine, and brain tissue were collected. We found that systolic BP was higher in O-NS (117 +/- 1.2 mm Hg) than in A-NS (105 +/- 0.8 mm Hg) rats (P < 0.05). Furthermore, BP was higher in O-HS (124 +/- 1.4 mm Hg) than in O-NS (117 +/- 1.2 mm Hg) rats (P < 0.05). Moreover, anxiety-like behavior (light-dark and open-field tests) was not different between A-NS and O-NS rats but was greater in O-HS rats than in A-NS, O-NS, or A-HS rats (P < 0.05). Short-term memory (radial arm water maze test) was similar in A-NS and O-NS rats but was significantly impaired in O-HS rats compared with A-NS, O-NS, or A-HS rats (P < 0.05). Furthermore, oxidative stress variables (in plasma, urine, and brain) as well as corticosterone (plasma) were greater in O-HS rats when compared with A-NS, O-NS, or A-HS rats (P < 0.05). The antioxidant enzyme glyoxalase-1 expression was selectively reduced in the hippocampus and amygdala of O-HS rats compared with A-NS, O-NS, or A-HS rats (P < 0.05), whereas other antioxidant enzymes, glutathione reductase 1, manganese superoxide dismutase (SOD), and Cu/Zn SOD remained unchanged. We suggest that salt-sensitive hypertension and behavioral derangement are associated with a redox imbalance in the brain of aged FBN rats"

  • Midlife and Late-Life Blood Pressure and Dementia in Japanese Elderly: The Hisayama Study - Hypertension. 2011 May 9 - "We followed up a total of 668 community-dwelling Japanese individuals without dementia, aged 65 to 79 years, for 17 years and examined the associations of late-life and midlife hypertension with the risk of vascular dementia and Alzheimer disease using the Cox proportional hazards model ... The age- and sex-adjusted incidence of vascular dementia significantly increased with elevated late-life blood pressure levels (normal: 2.3, prehypertension: 8.4, stage 1 hypertension: 12.6, and stage 2 hypertension: 18.9 per 1000 person-years; P(trend)<0.001), whereas no such association was observed for Alzheimer disease (P(trend)=0.88). After adjusting for potential confounding factors, subjects with prehypertension and stage 1 or stage 2 hypertension had 3.0-fold, 4.5-fold, and 5.6-fold greater risk of vascular dementia, respectively, compared with subjects with normal blood pressure. Likewise, there was a positive association of midlife blood pressure levels with the risk of vascular dementia but not with the risk of Alzheimer disease. Compared with those without hypertension in both midlife and late life, subjects with midlife hypertension had an ≈5-fold greater risk of vascular dementia, regardless of late-life blood pressure levels. Our findings suggest that midlife hypertension and late-life hypertension are significant risk factors for the late-life onset of vascular dementia but not for that of Alzheimer disease in a general Japanese population. Midlife hypertension is especially strongly associated with a greater risk of vascular dementia, regardless of late-life blood pressure levels"

  • Dementia risk tied to blood sugar level, even with no diabetes - Science Daily, 8/7/13 - "more than 2,000 Group Health patients age 65 and older in the Adult Changes in Thought (ACT) study ... in people without diabetes, risk for dementia was 18 percent higher for people with an average glucose level of 115 milligrams per deciliter compared to those with an average glucose level of 100 mg/dl. And in people with diabetes, whose blood sugar levels are generally higher, dementia risk was 40 percent higher for people with an average glucose level of 190 mg/dl compared to those with an average glucose level of 160 mg/dl ... The most interesting finding was that every incrementally higher glucose level was associated with a higher risk of dementia in people who did not have diabetes" - [Abstract]
  • People With Impaired Glucose Tolerance Can Show Cognitive Dysfunction -Science Daily, 7/16/13 - "she examined 31 previous studies regarding cognitive performance under various dietary conditions. She found that the impaired glucose tolerance group showed difficulties in 12 of 27 cognitive test outcomes, including word recognition, visual verbal learning test, visual spatial learning test, psychomotor test and Corsi block-tapping. The impaired glucose tolerance group was made up of all middle-aged women who appeared to be in general good health ... She pointed to a 2009 Japanese study of 129 people in their 80s, 55 of whom had impaired glucose tolerance or Type 2 diabetes. All the subjects in the study consumed more than 30 grams of dietary fiber per day and exercised two to four times per week over a two-year period. Within that timeframe, the 36 people with impaired glucose tolerance showed improvements in delayed recall and block design tests. The Type 2 diabetes group showed improvement in dementia, delayed recall and their mental state"
  • Putting Off Retirement May Help Stave Off Alzheimer's - WebMD, 7/15/13 - "Researchers analyzing health and insurance records of more than 429,000 self-employed workers found a 3 percent reduction in dementia risk for each extra year at the age of retirement. Workers evaluated had been retired for an average of more than 12 years, and 2.65 percent of the group had dementia ... There seems to be growing evidence that staying cognitively [mentally] active is really important to reducing a person's risk, and perhaps professional activity may be one of those cognitive activities ... noted several caveats to keep in mind when interpreting the study's meaning ... self-employed workers may be inherently different than company-employed workers, with differences in skill sets, work environment, stress and social mobility that might affect the study's results"
  • Do dietary patterns influence cognitive function in old age? - Int Psychogeriatr. 2013 Jun 4:1-15 - "Our results suggest a pattern of reverse causation or confounding; a higher childhood cognitive ability (and adult socioeconomic status) predicts adherence to a "healthy" diet and better cognitive performance in old age. Our models show no direct link between diet and cognitive performance in old age; instead they are related via the lifelong-stable trait of intelligence"

  • Effects of Type 2 Diabetes on 12-Year Cognitive Change: Results from the Maastricht Aging Study - Diabetes Care. 2012 Dec 28 - "Individuals with baseline type 2 diabetes show accelerated cognitive decline, particularly in information-processing speed and executive function, compared with individuals without diabetes. In incident diabetes, decline in speed becomes detectable first, and cognitive decline seems to increase with increasing exposure time"
  • Even in normal range, high blood sugar linked to brain shrinkage - Science Daily, 9/3/12 - "The study involved 249 people age 60 to 64 who had blood sugar in the normal range as defined by the World Health Organization. The participants had brain scans at the start of the study and again an average of four years later ... Those with higher fasting blood sugar levels within the normal range and below 6.1 mmol/l (or 110 mg/dL) were more likely to have a loss of brain volume in the areas of the hippocampus and the amygdala, areas that are involved in memory and cognitive skills, than those with lower blood sugar levels. A fasting blood sugar level of 10.0 mmol/l (180 mg/dL) or higher was defined as diabetes and a level of 6.1 mmol/l (110 mg/dL) was considered impaired, or prediabetes ... blood sugar on the high end of normal accounted for six to 10 percent of the brain shrinkage"
  • Your Brain -- Use It or Lose It - Medscape, 7/12/12 - "It is not yet known whether an active cognitive lifestyle and social engagement directly affect the brain and cerebral vasculature, whether people who are more resilient neurologically have more active cognitive lifestyles, or whether predisposition to greater resiliency is linked to predisposition to cognitive activity. However, improvement of cognitive decline by cognitive retraining (JW Psychiatry Oct 17 2011) suggests that a two-way interaction between the environment and the brain might protect against dementia via several mechanisms"
  • Diabetes shrinks elderly brain - Science Daily, 5/7/12 - "While some brain volume loss is a normal part of aging, the researchers found that elderly people with blood sugar levels in flux, as well as type 2 diabetes, lost almost two and a half times more brain volume than their peers over two years. The reduction in size of the frontal lobe -- associated with higher mental functions like decision-making, emotional control, and long term memory -- has a significant impact on cognitive function and quality of life"
  • Poor Dental Health Linked to Dementia Onset - Medscape, 4/13/12 - "those who had few teeth and who did not use dentures or who did not visit a dentist regularly had a significantly higher risk for dementia onset than the participants who practiced better dental health practices ... Gum Disease a Likely Culprit ... The participants who had few teeth without dentures had a significantly higher risk of developing dementia than those who had 20 teeth or more (adjusted hazard ratio [HR], 1.85 ... Not having a regular dentist was also a significant risk factor for dementia onset (HR, 1.44 ... One possibility is that periodontal disease...increases concentrations of circulating inflammatory markers [that] may be involved in the pathogenesis of dementia. A second possibility is that poor nutrition, including decreased intake of vitamins, may result from tooth loss and dementia onset"
  • Brain insulin resistance contributes to cognitive decline in Alzheimer's disease - Science Daily, 3/23/12 - "This is the first study to directly demonstrate that insulin resistance occurs in the brains of people with Alzheimer's disease ... Our research clearly shows that the brain's ability to respond to insulin, which is important for normal brain function, is going offline at some point ... We believe that brain insulin resistance may be an important contributor to the cognitive decline associated with Alzheimer's disease ... The risk of developing Alzheimer's disease is increased by 50 percent in people with diabetes ... insulin resistance of the brain occurs in Alzheimer's disease independent of whether someone has diabetes ... The investigators used samples of postmortem brain tissue from non-diabetics who had died with Alzheimer's disease, stimulated the tissue with insulin, and measured how much the insulin activated various proteins in the insulin-signaling pathways ... three insulin-sensitizing medicines are already approved by the FDA for treatment of diabetes. These drugs readily cross the blood-brain barrier and may have therapeutic potential to correct insulin resistance in Alzheimer's disease and MCI" - Note:  I suspected this for a long time.  It doesn't say what those three drugs are but I'm guessing metformin and Actos are two of them.  I don't have diabetes but I take low doses of both.  My doc says I'm crazy.  See metformin and pioglitazone (Actos) at OffshoreRx1.com.
  • More Evidence That ARBs Have Cognitive Benefits - Medscape, 3/23/12 - "After stopping their antihypertensive medications, the patients were randomly assigned to the ARB candesartan (n = 20), the angiotensin-converting enzyme inhibitor (ACEI) lisinopril (n = 18), or the diuretic hydrochlorothiazide (n = 15) ... After adjustment for age and baseline score on the Mini-Mental State Examination, patients taking candesartan showed the greatest improvements on tests assessing executive function ... Our findings further support observational data showing that ARB use is associated with lower risk of dementia and Alzheimer disease compared with the use of ACEIs or other antihypertensives ... As reported previously by Medscape Medical News, Dr. Kehoe and colleagues recently published a study showing a 53% lower risk for Alzheimer's disease in older adults prescribed an ARB compared with those prescribed other antihypertensive agents"
  • Impaired Insulin Sensitivity as Indexed by the HOMA Score Is Associated With Deficits in Verbal Fluency and Temporal Lobe Gray Matter Volume in Elderly Men and Women - Diabetes Care. 2012 Feb 1 - "homeostasis model assessment of insulin resistance (HOMA-IR) ... The HOMA-IR was negatively correlated with verbal fluency performance, brain size (S1), and temporal lobe gray matter volume in regions known to be involved in speech production (Brodmann areas 21 and 22, respectively) ... These cross-sectional findings suggest that both pharmacologic and lifestyle interventions improving insulin signaling may promote brain health in late life but must be confirmed in patient studies"
  • Depressive symptoms, antidepressant use, and future cognitive health in postmenopausal women: the Women's Health Initiative Memory Study - Int Psychogeriatr. 2012 Feb 3:1-13 - "mild cognitive impairment (MCI) ... Antidepressant use was associated with a 70% increased risk of MCI, after controlling for potential covariates including the degree of depressive symptom severity. Selective serotonin reuptake inhibitors (SSRIs) and tricyclic antidepressants (TCAs) were both associated with MCI (SSRIs: hazard ratios (HR), 1.78 [95% CI, 1.01-3.13]; TCAs: HR, 1.78 [95% CI, 0.99-3.21]). Depressed users (HR, 2.44 [95% CI, 1.24-4.80]), non-depressed users (HR, 1.79 [95% CI, 1.13-2.85]), and depressed non-users (HR, 1.62 [95% CI, 1.13-2.32]) had increased risk of incident MCI. Similarly, all three groups had increased risk of either MCI or dementia, relative to the control cohort"
  • Study: Mental decline can start at 45 - USATODAY.com, 1/6/12 - "Among men aged 45 to 49, reasoning skills declined by nearly 4 percent, and for those aged 65 to 70 those skills dropped by about nearly 10 percent ... For women, the decline in reasoning approached 5 percent for those aged 45 to 49 and about 7 percent for those 65 to 70, the researchers found"
  • Glucose tolerance status and risk of dementia in the community: The Hisayama Study - Neurology. 2011 Sep 20;77(12):1126-34 - "The age- and sex-adjusted incidence of all-cause dementia, Alzheimer disease (AD), and vascular dementia (VaD) were significantly higher in subjects with diabetes than in those with normal glucose tolerance. These associations remained robust even after adjustment for confounding factors for all-cause dementia and AD, but not for VaD (all-cause dementia: adjusted hazard ratio [HR] = 1.74, 95% confidence interval [CI] = 1.19 to 2.53, p = 0.004; AD: adjusted HR = 2.05, 95% CI = 1.18 to 3.57, p = 0.01; VaD: adjusted HR = 1.82, 95% CI = 0.89 to 3.71, p = 0.09). Moreover, the risks of developing all-cause dementia, AD, and VaD significantly increased with elevated 2-hour postload glucose (PG) levels even after adjustment for covariates, but no such associations were observed for fasting plasma glucose (FPG) levels: compared with those with 2-hour PG levels of <6.7 mmol/L, the multivariable-adjusted HRs of all-cause dementia and AD significantly increased in subjects with 2-hour PG levels of 7.8 to 11.0 mmol/L or over, and the risk of VaD was significantly higher in subjects with levels of ≥11.1 mmol/L ... Our findings suggest that diabetes is a significant risk factor for all-cause dementia, AD, and probably VaD. Moreover, 2-hour PG levels, but not FPG levels, are closely associated with increased risk of all-cause dementia, AD, and VaD"
  • How Exercise Can Keep the Brain Fit - NYTimes.com, 7/27/11 - "While the wholly sedentary volunteers, and there were many of these, scored significantly worse over the years on tests of cognitive function, the most active group showed little decline. About 90 percent of those with the greatest daily energy expenditure could think and remember just about as well, year after year ... The same message emerged from another study published last week in the same journal. In it, women, most in their 70s, with vascular disease or multiple risk factors for developing that condition completed cognitive tests and surveys of their activities over a period of five years. Again, they were not spry. There were no marathon runners among them. The most active walked. But there was “a decreasing rate of cognitive decline” among the active group, the authors wrote. Their ability to remember and think did still diminish, but not as rapidly as among the sedentary ...scientists from the Aging, Mobility and Cognitive Neuroscience Laboratory at the University of British Columbia and other institutions have shown, for the first time, that light-duty weight training changes how well older women think and how blood flows within their brains. After 12 months of lifting weights twice a week, the women performed significantly better on tests of mental processing ability than a control group of women who completed a balance and toning program, while functional M.R.I. scans showed that portions of the brain that control such thinking were considerably more active in the weight trainers"
  • Humans Alone See Brains Shrink With Age, Researchers Find - WSJ, 7/26/11 - "they found the human brains lost significant volume over time, while the chimpanzees didn't ... Stress can affect brain size. So can depression, research shows. Diet can be a factor, too. More broadly, though, humanity's unusual shrinking brain just may be the price our species pays for living so much longer than other primates ... During those extra decades of life, natural cell-repair mechanisms may wear out and neural circuits wither, the researchers said. As the brain normally ages, it acquires the neural equivalent of sore knees and stiff fingers. Natural grooves in the brain widen. Healthy swellings subside. And tangles of damaged neurons become dense thickets of dysfunctional synapses"
  • Plasma homocysteine and cognitive decline in older hypertensive subjects - Int Psychogeriatr. 2011 May 6:1-9 - "Higher homocysteine showed an independent association with greater cognitive decline in three domains: speed of cognition (β = -27.33, p = 0.001), episodic memory (β = -1.25, p = 0.02) and executive function (β = -0.05, p = 0.04). The association with executive function was no longer significant after inclusion of folate in the regression model (β = -0.032, p = 0.22). Change in working memory and attention were not associated with plasma homocysteine, folate or B12. High homocysteine was associated with greater decline with a Cohen's d effect size of approximately 0.7 compared to low homocysteine. Conclusions: In a population of older hypertensive patients, higher plasma homocysteine was associated with cognitive decline"

  • Study links inflammation in brain to some memory decline - Science Daily, 4/13/11 - "adults with measureable levels of C reactive protein recalled fewer words and had smaller medial temporal lobes ... Scientists don't know if the inflammation indicated by the C reactive protein is the cause of the memory loss, if it reflects a response to some other disease process or if the two factors are unrelated. But if inflammation causes the cognitive decline, relatively simple treatments could help"
  • High cholesterol and blood pressure in middle age tied to early memory problems - Science Daily, 2/21/11 - "people who had higher cardiovascular risk were more likely to have lower cognitive function and a faster rate of overall cognitive decline compared to those with the lowest risk of heart disease. A 10-percent higher cardiovascular risk was associated with poorer cognitive test scores in all areas except reasoning for men and fluency for women. For example, a 10 percent higher cardiovascular risk was associated with a 2.8 percent lower score in the test of memory for men and a 7.1 percent lower score in the memory test for women ... Higher cardiovascular risk was also associated with a 10-year faster rate of overall cognitive decline in both men and women compared to those with lower cardiovascular risk"

  • Promising drug candidate reverses age-related memory loss in mice - Science Daily, 10/12/10 - "Such memory loss has been linked with high levels of 'stress' steroid hormones known as glucocorticoids which have a deleterious effect on the part of the brain that helps us to remember. An enzyme called 11beta-HSD1 is involved in making these hormones and has been shown to be more active in the brain during aging ... We found that life-long partial deficiency of 11beta-HSD1 prevented memory decline with aging. But we were very surprised to find that the blocking compound works quickly over a few days to improve memory in old mice suggesting it might be a good treatment for the already elderly ... We previously showed that carbenoxolone, an old drug that blocks multiple enzymes including 11beta-HSD1, improves memory in healthy elderly men and in patients with type 2 diabetes after just a month of treatment, so we are optimistic that our new compounds will be effective in humans. The next step is to conduct further studies with our preclinical candidate to prove that the compound is safe to take into clinical trials, hopefully within a year"
