Why Coffee May Reduce Diabetes Risk - WebMD, 1/13/12 -
"The Chinese researchers looked at three major active
compounds in coffee and their effect on stopping
the toxic accumulation of the protein: ... Caffeine ... Caffeic acid or CA ...
Chlorogenic acid or CGA ... All three had an effect. However, caffeic acid was
best" - Note: I've always thought that
artichoke extract which is 6% chlorogenic acid
would do the same thing:

Chlorogenic acid - Wikipedia, the free encyclopedia -
"Chlorogenic acid is a hydroxycinnamic acid, a
member of a family of naturally occurring organic compounds. These are
esters of polyphenolic caffeic acid and cyclitol (-)-quinic acid"
Diet
counts: Iron intake in teen years can impact brain in later life - Science
Daily, 1/12/12 - "healthy brain wiring in adults
depended on having good iron levels in your teenage years ... This connection
was a lot stronger than we expected, especially as we were looking at people who
were young and healthy -- none of them would be considered iron-deficient ...
You wouldn't think the iron in our diet would
affect the brain so much in our teen years. But it turns out that it matters
very much. Because myelin speeds your brain's communications, and iron is vital
for making myelin, poor iron levels in childhood erode your brain reserves which
you need later in life to protect against aging and Alzheimer's" - See

Are Fears That Deodorant Causes Breast Cancer Unfounded? - WebMD, 1/12/12 -
"It has to do with certain underarm products that
contain preservatives called parabens. These
chemicals can act like the hormone estrogen in the body ... Parabens such as
methylparaben, ethylparaben, propylparaben, butylparaben, isopropylparaben, and
isobutylparaben are also found in makeup, moisturizers, and hair care and
shaving products ... The new study included 40 women with breast cancer who
chose to have a mastectomy. Researchers looked at four samples of breast tissue
from each woman ... Fully 99% of the tissue samples had evidence of at least one
paraben, and 60% showed evidence of five ... The study suggests that if there is
a relationship between parabens and breast cancer, it may be a complex one"
More vitamin E linked to better mental function: Study - Nutra USA, 1/11/12
- "Alzheimer patients
were 85% less likely to have the highest levels of
vitamin E, compared with people with normal cognitive function ... There are
eight forms of vitamin E: four tocopherols (alpha, beta, gamma, delta) and four
tocotrienols (alpha, beta, gamma, delta) ... the new study is said to be the
first to evaluate all the forms of vitamin E in relation to Alzheimer’s disease

Breakfast fail! Worst supermarket cereals revealed - MSNBC, 1/11/12 -
"Eating breakfast pays off—numerous studies indicate
that eating in the A.M. is key in losing and maintaining weight. Not only have
studies shown that regular breakfast eaters have lower BMIs, but they also
typically have lower waist-to-hip ratios than those that skip. Cereal is a great
option—it’s a quick and convenient way to get in on those belly-shrinking
benefits. That said, not all cereals are equal"
A Love Drug? Oxytocin, the 'Cuddle Chemical' to Scientists, Makes Mothers More
Kind, Say Researchers - ABC News, 1/11/12 - "There
is hope that the hormone could be used to help patients suffering from a range
of psychiatric disorders that affect social interactions, including autism and
schizophrenia ... They found a clear correlation between the levels of
oxytocin and the amount of attention each new
mother paid to her baby. The first trimester of the pregnancy turned out to be
the most important because higher levels of the hormone during that period
coincided with much more bonding and affection after the birth ... At about the
same time as the Israel study, Paul Zak of Claremont University in California
was giving doses of oxytocin, and a placebo, to participants who were instructed
to split a sum of money with a stranger. The results were "overwhelming,"
according to that study. Those given oxytocin offered 80 percent more money than
those given a placebo ... in the first hour or two after getting the hormone,
the monkeys actually became more selfish. It took a couple of hours for them to
become more social and compassionate" -

Plasma
vitamin C concentrations in patients on routine hemodialysis and its
relationship to patients morbidity and mortality Int J Vitam Nutr Res. 2011
Jul;81(4):197-203 - "hemodialysis
(HD) patients ... Forty-nine patients (53.8 %) had low levels of
vitamin C concentration. There was a significant relationship between
vitamin C insufficiency and presence of any co-morbidity in HD patients (p <
0.05). There was a significant difference in vitamin C concentrations between
patients without co-morbidities and those with cardiovascular ones
(F[2,88]=3.447, p = 0.036). Twenty-two (24.2 %) patients died over a median
duration of 227 days. There was a significant difference in time to death of
patients with and without low levels of vitamin C concentration (p = 0.04).
Conclusions: The results showed lower plasma vitamin C levels in HD patients who
suffered any co-morbidity and sooner time to death in these patients" -

Vitamin D
Status and Cytokine Levels in Patients with Crohns Disease - Int J Vitam
Nutr Res. 2011 Jul;81(4):205-10 - "Results: IL-10 levels
were significantly lower in patients with vitamin D
insufficiency compared with the vitamin D replete group (mean and SE 2.48 +/-
0.51 v 6.77 +/- 2.49 pg/mL, p < 0.001). There were, however, no differences in
serum TNF-alpha or CRP levels based on vitamin D status. The use of a vitamin D
supplement at a low dose (200 IU) did not significantly influence IL-10 levels.
Conclusion: Circulating levels of IL-10, but not TNF-alpha, were significantly
lower in CD patients with inadequate serum
25(OH)D. This suggests that poor vitamin D status may be linked to reduced
anti-inflammatory capacity in this group"

Effects of
Pycnogenol on endothelial function in patients with stable coronary artery
disease: a double-blind, randomized, placebo-controlled, cross-over study -
Eur Heart J. 2012 Jan 11 - "Patients received
Pycnogenol (200 mg/day) for 8 weeks followed
by placebo or vice versa on top of standard cardiovascular therapy ... In
CAD
patients, Pycnogenol treatment was associated with an improvement of FMD from
5.3 +/- 2.6 to 7.0 +/- 3.1 (P < 0.0001), while no change was observed with
placebo (5.4 +/- 2.4 to 4.7 +/- 2.0; P = 0.051). This difference between study
groups was significant [estimated treatment effect 2.75; 95% confidence interval
(CI): 1.75, 3.75, P < 0.0001]. 15-F(2t)-Isoprostane, an index of oxidative
stress, significantly decreased from 0.71 +/- 0.09 to 0.66 +/- 0.13 after
Pycnogenol treatment, while no change was observed in the placebo group (mean
difference 0.06 pg/mL with an associated 95% CI (0.01, 0.11), P = 0.012].
Inflammation markers, platelet adhesion, and blood pressure did not change after
treatment with Pycnogenol or placebo. Conclusion This study provides the first
evidence that the antioxidant Pycnogenol improves endothelial function in
patients with CAD by reducing oxidative stress" - See

Subclinical
Thyroid Dysfunction and the Risk of Heart Failure in Older Persons at High
Cardiovascular Risk - J Clin Endocrinol Metab. 2012 Jan 11 -
"Over 3.2 yr follow-up, the rate of heart failure was
higher for subclinical hyperthyroidism compared with euthyroidism [age- and
sex-adjusted hazard ratio (HR) = 2.93, 95% confidence interval (CI) = 1.37-6.24,
P = 0.005; multivariate-adjusted HR = 3.27, 95% CI = 1.52-7.02, P = 0.002).
Subclinical hypothyroidism (only at threshold >10 mIU/liter) was associated with
heart failure (age- and sex-adjusted HR = 3.01, 95% CI = 1.12-8.11, P = 0.029;
multivariate HR = 2.28, 95% CI = 0.84-6.23). There were no strong evidence of an
association between subclinical thyroid dysfunction and cardiovascular events or
mortality, except in those with TSH below 0.1 or over 10 mIU/liter and not
taking pravastatin. Conclusion: Older people at high cardiovascular risk with
low or very high TSH along with normal free T(4) appear at increased risk of
incident heart failure"

Vegetarian
diets and blood pressure among white subjects: results from the Adventist Health
Study-2 (AHS-2) - Public Health Nutr. 2012 Jan 10:1-8 -
"Covariate-adjusted regression analyses demonstrated
that the vegan vegetarians had lower
systolic and diastolic BP (mmHg) than
omnivorous Adventists (β = -6.8, P < 0.05 and β = -6.9, P < 0.001). Findings for
lacto-ovo vegetarians (β = -9.1, P < 0.001 and β = -5.8, P < 0.001) were
similar. The vegetarians (mainly the vegans) were also less likely to be using
antihypertensive medications. Defining hypertension as systolic BP > 139 mmHg or
diastolic BP > 89 mmHg or use of antihypertensive medications, the odds ratio of
hypertension compared with omnivores was 0.37 (95 % CI 0.19, 0.74), 0.57 (95 %
CI 0.36, 0.92) and 0.92 (95 % CI 0.50, 1.70), respectively, for vegans,
lacto-ovo vegetarians and partial vegetarians. Effects were reduced after
adjustment for BMI ... CONCLUSIONS: We conclude from this relatively large study
that vegetarians, especially vegans, with otherwise diverse characteristics but
stable diets, do have lower systolic and diastolic BP and less hypertension than
omnivores. This is only partly due to their lower body mass"

fish reduces risk of Alzheimer's disease - Science Daily, 11/30/11 -
"This is the first study to establish a direct
relationship between fish consumption, brain structure and Alzheimer's risk ...
people who consumed baked or broiled fish at least one time per week had better
preservation of gray matter volume on MRI in brain areas at risk for Alzheimer's
disease ... Each patient underwent 3-D volumetric MRI of the brain. Voxel-based
morphometry, a brain mapping technique that measures gray matter volume, was
used to model the relationship between weekly fish consumption at baseline and
brain structure 10 years later ... consumption of baked or broiled fish on a
weekly basis was positively associated with gray matter volumes in several areas
of the brain. Greater hippocampal, posterior cingulate and orbital frontal

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

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" -

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" -

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"

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"

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

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"

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"

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

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"

Improved
cognitive-cerebral function in older adults with chromium supplementation
- Nutr Neurosci. 2010 Jun;13(3):116-22 - "In a
placebo-controlled, double-blind trial, we randomly assigned 26 older adults
to receive either chromium picolinate (CrPic) or placebo for 12 weeks ...
Although learning rate and retention were not enhanced by CrPic
supplementation, we observed reduced semantic interference on learning,
recall, and recognition memory tasks. In addition, fMRI indicated
comparatively increased activation for the CrPic subjects in right thalamic,
right temporal, right posterior parietal, and bifrontal regions. These
findings suggest that supplementation with CrPic can enhance cognitive
inhibitory control and cerebral function in older adults at risk for

blood flow to the brain ... monkeys who exercised regularly at an intensity
that would improve fitness in middle-aged people learned to do tests of
cognitive function faster and had greater blood volume in the brain's motor
cortex than their sedentary counterparts ... This suggests people who
exercise are getting similar benefits ... When the researchers examined
tissue samples from the brain's motor cortex, they found that mature monkeys
that ran had greater vascular volume than middle-aged runners or sedentary
animals. But those blood flow changes reversed in monkeys that were
sedentary after exercising for five months"

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
demographically matched sample who consumed a berry placebo beverage in a

- Br J Nutr. 2009 Oct 13:1-11 - "This indicates that
oligomers result in an increase in the densities of axons, dendrites and

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"

Midlife Levels of Systolic Blood Pressure as a Public Health Strategy to Reduce

with those with SBP <120 mm Hg, untreated, and <50 years of age at baseline,
17.7% (95% CI: 4.6% to 29.1%) of the cases were attributable to prehypertensive
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
systolic BP >/=120 mm Hg, translating into 17 excess cases per 1000. Although
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"

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"

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"

(blood sugar) may have a role in this relationship ... in people with type 2
diabetes, higher levels of haemoglobin A1C (a
measure of average blood glucose) are significantly associated with poorer
performance on three cognitive tasks which require memory, speed and ability to
manage multiple tasks at the same time. A higher A1C level was also associated
with a lower score on a test of global cognitive function ... lowering A1C
levels could slow the accelerated rate of cognitive decline experienced by
people with diabetes"

Telmisartan prevented
cognitive decline partly due to PPAR-gamma activation - Biochem Biophys
Res Commun. 2008 Aug 17 - "Pretreatment with a
non-hypotensive dose of telmisartan significantly inhibited such cognitive
decline. Interestingly, co-treatment with GW9662, a PPAR-gamma antagonist,
partially inhibited this improvement of cognitive decline. Another ARB,
losartan, which has less PPAR-gamma agonistic effect, also inhibited
Abeta-injection-induced cognitive decline; however the effect was smaller
than that of telmisartan and was not affected by GW9662. Immunohistochemical
staining for Abeta showed the reduced Abeta deposition in
telmisartan-treated mice. However, this reduction was not observed in mice
co-administered GW9662. These findings suggest that ARB has a preventive
effect on cognitive impairment in Alzheimer disease, and telmisartan, with
PPAR-gamma activation, could exert a stronger effect"
