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

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"

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 -

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%" -

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

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

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

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

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

"Metformin makes muscle tissue more receptive to
insulin, a hormone necessary for sugar (glucose) to get into the body's cells

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

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

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

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

"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"

B vitamins may slow cognitive decline: Oxford University study - Nutra USA,
10/25/11 - "A daily combination of folic acid, and
vitamins B6 and B12 was associated with a 30% reduction in levels of the amino
acid homocysteine, and improvements in a range of mental tests, including global
cognition and episodic memory ... One interpretation [of the data] is that
lowering homocysteine concentrations by administering B vitamins slows brain
atrophy, which in turn slows both cognitive and clinical decline ... The Vitacog
study involved 266 people over the age of 70 with diagnosed mild cognitive
impairment. Participants were randomly assigned to receive either placebo or a B
vitamin supplement providing 0.8 mg per day of folic acid, 0.5 mg of vitamin B12

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

Vitamin B12,
cognition, and brain MRI measures: A cross-sectional examination -
Neurology. 2011 Sep 27;77(13):1276-82 - "Concentrations
of all vitamin B12-related markers, but not serum vitamin B12 itself, were
associated with global cognitive function and with total brain volume.
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. Vitamin B12 status may affect the
brain through multiple mechanisms" - See

Effects of
n-3 fatty acids, EPA v. DHA, on depressive symptoms, quality of life, memory and
executive function in older adults with mild cognitive impairment: a 6-month
randomised controlled trial - Br J Nutr. 2011 Sep 20:1-12 -
"Depressive symptoms may increase the risk of
progressing from mild cognitive impairment (MCI) to dementia. Consumption of n-3
PUFA may alleviate both cognitive decline and depression ... A total of fifty
people aged >65 years with MCI were allocated to receive a supplement rich in
EPA (1.67 g EPA+0.16 g DHA/d; n 17), DHA (1.55 g DHA+0.40 g EPA/d; n 18) or the
n-6 PUFA linoleic acid (LA; 2.2 g/d; n 15). Treatment allocation was by
minimisation based on age, sex and depressive symptoms (Geriatric Depression
Scale, GDS). 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" -

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

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"

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

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"

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

vitamins and the aging brain examined - Science Daily, 8/17/10 -
"An analysis of volunteers' blood samples showed
that lower levels of one B vitamin, folate, were associated with symptoms of
dementia and poor brain function, also called "cognitive decline," ... In
women, but not men, low levels of folate were associated with symptoms of
depression. In fact, female volunteers whose plasma folate levels were in
the lowest third were more than twice as likely to have symptoms of
depression as volunteers in the highest third ... In research with vitamin
B-12, the SALSA team determined that a protein known as holoTC, short for
holotranscobalamin, might be key to a new approach for detecting cognitive
decline earlier and more accurately"

basis of tertiles (T) of serum 25(OH)D (<47.6 (T(1)); 47.6-85.8 (T(2)); and
>85.8 (T(3)) nmol/l), fewer errors in SWM test scores occurred in subjects in
the third T when compared with the first T (P<0.05-0.084). Stratification by sex
showed that these differences between tertiles strengthened (P<0.001-0.043) in

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

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

that would be expected to mitigate neurodegeneration ... At 12 weeks,
improved paired associate learning (p = 0.009) and word list recall (p =
0.04) were observed. In addition, there were trends suggesting reduced
depressive symptoms (p = 0.08) and lower glucose levels (p = 0.10). We also
compared the memory performances of the blueberry subjects with a

Soya
isoflavone supplementation enhances spatial working memory in men - Br J
Nutr. 2009 Jun 1:1-7 - "Volunteers were randomised
to take four capsules/d containing soya isoflavones (116 mg isoflavone
equivalents/d: 68 mg daidzein, 12 mg genistein, 36 mg glycitin) or placebo
for 6 weeks, and the alternate treatment during the following 6 weeks.
Assessments of memory (verbal episodic, auditory and working), executive
function (planning, attention, mental flexibility) and visual-spatial
processing were performed at baseline and after each treatment period.
Isoflavone supplementation significantly improved spatial working memory (P
= 0.01), a test in which females consistently perform better than males.
Compared with placebo supplementation, there were 18 % fewer attempts (P =
0.01), 23 % fewer errors (P = 0.02) and 17 % less time (P = 0.03) required
to correctly identify the requisite information. Isoflavones did not affect
auditory and episodic memory (Paired Associate Learning, Rey's Auditory
Verbal Learning Task, Backward Digit Span and Letter-Number Sequencing),
executive function (Trail Making and Initial Letter Fluency Task) or
visual-spatial processing (Mental Rotation Task). Isoflavone supplementation
in healthy males may enhance cognitive processes which appear dependent on

Is
Vitamin D Deficiency Linked To Alzheimer's Disease And Vascular Dementia?
- Science Daily, 5/26/09 - "Several studies have
correlated tooth loss with development of cognitive impairment and
Alzheimer's disease or vascular dementia. There are two primary ways that
people lose teeth: dental caries and periodontal disease. Both conditions
are linked to low vitamin D levels, with induction of human cathelicidin by
1,25-dihydroxyvitamin D being the mechanism ... There is also laboratory
evidence for the role of vitamin D in neuroprotection and reducing
inflammation, and ample biological evidence to suggest an important role for
vitamin D in brain development and function ... those over the age of 60
years should consider having their serum 25(OH)D tested, looking for a level
of at least 30 ng/mL but preferably over 40 ng/mL, and supplementing with

brain disorder for which there is no cure; available therapies only decrease
cognitive decline. Huperzine A, an alkaloid derived from Chinese club moss
(H. serrata), acts as a selective inhibitor of acetylcholinesterase and may
also display neuroprotective properties. Preliminary data suggest that
huperzine A may improve cognition; studies ranging from 8 to 12 weeks have
found improvements in the Mini-Mental State Examination score of 1-5 points
... Although use of huperzine A has shown promising results in patients with
AD, data supporting its use are limited by weak study design" - See

Neuroprotective Effects of (-)-Epigallocatechin-3-gallate on Aging Mice
Induced by D-Galactose - Biol Pharm Bull. 2009 Jan;32(1):55-60 -
"aim of the present study was to investigate the
protective effects of (-)-epigallocatechin-3-gallate (EGCG), the main
polyphenolic constituent of green tea ... Oral administration of EGCG (2
mg/kg or 6 mg/kg) for 4 weeks significantly improved the cognitive deficits
in mice and elevated T-SOD and GSH-Px activities, decreased MDA contents in
the hippocampus, and reduced the cell apoptosis index and expression of
cleaved caspase-3 in the mouse hippocampus. The results suggest that EGCG

A High-Salt
Diet Further Impairs Age-Associated Declines in Cognitive, Behavioral, and

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

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,

levels (SBP: 120 to <140 mm Hg) of SBP, translating into 11 excess cases per
1000. Among those who did not report taking antihypertensive medication in
midlife, 27% (95% CI: 8.9% to 42.1%) of dementia cases can be attributed to

population-attributable risk estimates for population subgroups may differ by
relative risk for dementia or prevalence of elevated levels of blood pressure,
these data suggest that reducing midlife systolic BP is an effective prevention
strategy to reduce risk for late-life dementia"

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

older hypertensive patients, higher plasma homocysteine was associated with
cognitive decline"

Packing
on the pounds in middle age linked to dementia - Science Daily, 5/2/11 -
"people who were overweight or obese at midlife had an
80 percent higher risk of developing dementia, Alzheimer's disease or vascular
dementia in late life compared to people with normal BMI"

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"

Protein
in the urine: A warning sign for cognitive decline - Science Daily, 11/21/10
- "low amounts of albumin in the urine, at levels not
traditionally considered clinically significant, strongly predict faster
cognitive decline in older women ... participants with a urinary
albumin-to-creatinine ratio of >5 mcg/mg at the start of the study experienced
cognitive decline at a rate 2 to 7 times faster in all cognitive measures than
that attributed to aging alone over an average 6 years of follow-up"

High-Quality Relationships May Have Long-Term Protective Effect Against Dementia
- Medscape, 10/28/10 - "participants older than 65 years
showed those who reported being satisfied with their relationships at baseline
had a 23% reduced risk of developing dementia from 5 to 15 years later compared
with those who were not satisfied"

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"

Mild
memory loss is not a part of normal aging, new research finds - Science
Daily, 9/15/10 - "Simply getting older is not the cause
of mild memory lapses often called senior moments ... even the very early mild
changes in memory that are much more common in old age than dementia are caused
by the same brain lesions associated with Alzheimer's disease and other
dementias ... The very early mild cognitive changes once thought to be normal
aging are really the first signs of progressive dementia"

Gum
inflammation linked to Alzheimer's disease - Science Daily, 8/3/10 -
"cognitively normal subjects with periodontal
inflammation are at an increased risk of lower cognitive function compared to
cognitively normal subjects with little or no periodontal inflammation ...
subjects with Alzheimer's disease had a significantly higher level of antibodies
and inflammatory molecules associated with periodontal disease in their plasma
compared to healthy people ... the Digit Symbol Test, or DST, a part of the
standard measurement of adult IQ ... periodontal inflammation at age 70 was
strongly associated with lower DST scores at age 70. Subjects with periodontal
inflammation were nine times more likely to test in the lower range of the DST
compared to subjects with little or no periodontal inflammation" - Note:
See my
dental page. Gum disease has been linked to several other heath
conditions including diabetes and heart disease. Over the years I've tried
several methods for gum disease including floss,
Periostat
and Arestin and here is the only method
that worked:
-
Periogard - Needs a prescription but is usually available at you dentist
for around $10.
-
Sunstar Butler Proxabrush GUM Eez-Lok Handle
-
Sunstar Butler Proxabrush GUM Eez-Lok Handle - a better model than the
above
-
Sunstar
Butler GUM Proxabrush Refill Ultra Wide (618) - use this wide brush for
the back teeth
-
Butler 612 Soft Picks or
Butler Ultra-Fine - use these narrower brushes for the front teeth
-
Soak the brush in the Periogard than run it between your teeth.
