Recent Longevity News for the
seven days ending 3/28/12. You should consult your doctor if you are
taking any medications.
Salivary Testing for
Periodontal Disease - Medscape, 3/26/12 - "Salivary
samples were sent to the laboratory for a DNA-polymerase chain reaction (PCR)
test (My Perio Path®; OralDNA Labs; Brentwood, Tennessee) to test for the
presence of high-risk pathogens and a periodontal susceptibility test (PST®,
OralDNA Labs, Brentwood, Tennessee) for the probability of more severe
periodontal disease. The DNA bacteria test identifies the type and concentration
of pathogenic bacteria that are known to cause periodontal disease. The PST
detects variations in the genes for interleukin 1A and 1B that suggest a
predisposition for overexpression of inflammation and risk for periodontal
disease. These tests permit appropriate treatment of the patient's periodontal
disease, without overtreating or undertreating, and take the level of risk for
future disease and complications into consideration ... All of these pathogens
are associated with periodontal disease. Aa leukotoxin kills white blood cells
in a variety of ways, allowing pathogenic bacteria to survive the immune
response and releasing compounds that are essential for bacteria survival and
growth. Aa leukotoxin is involved in attachment loss in adolescents, indicating
that it plays a role in the pathogenesis of aggressive periodontitis ...
Specific home care instructions: Use a power toothbrush ... Use a water
irrigator ... Use antibacterial tooth paste ... Use antibacterial mouth rinse
... Eat a balanced diet high in antioxidants ... Take high-quality nutritional
supplementation ... Get adequate rest and exercise ... adjunct to treatment
based on the patient's bacterial profile: amoxicillin 500 mg 3 times daily for 8
days and metronidazole 500 mg twice daily for 8 days beginning on the last day
of periodontal therapy ... Taking into consideration the transmissible nature of
Aa, the odds that his wife has a similar periodontal pathogen profile are
substantial"
Packing
on the Pounds - The Daily, 3/26/12 - "The claims by
leading BPA critic Frederick vom Saal come as the
Food and Drug Administration is expected to rule this week — after four years of
study — on whether to ban the plastic additive from use in food packaging ...
Vom Saal told The Daily he will soon release a new study showing that mothers
who expose their fetuses to the bisphenol A run the risk of having obese
children ... BPA turns out to be a major factor in the number of fat cells that
a person will have later in life ... over the past few months, a slew of new
research has focused on the BPA-obesity link. Vom Saal’s findings are just the
latest new evidence that BPA may be playing a role in the global obesity
epidemic. Another study released in February by a Spanish research team showed
that even small amounts of BPA cause human adult islet cells to produce more fat
in the body ... It takes 90 days under the Toxic Substances Control Act to get a
chemical approved for sale on the market ... Getting a product off the market
that has been shown to be unsafe, on the other hand, takes somewhere between 25
and 50 years, because industry says we need definitive science"
Metformin Associated
With Lower Cancer Risk - Medscape, 3/26/12 - "During
up to 10 years of follow-up, metformin users
were less likely to receive cancer diagnoses than sulfonylurea users (hazard
ratio, 0.9; 95% confidence interval, 0.88–0.91) after adjustment for age, sex,
and several other variables. This 10% reduction was modest in relative terms but
highly statistically significant. Metformin-associated lower risks were noted
for cancers of the esophagus, stomach, colon, liver, pancreas, lung, breast, and
prostate ... If hyperinsulinemia really does promote cancer, metformin
theoretically could lower cancer risk in type 2 diabetic patients because it
lowers circulating glucose and insulin levels in patients with insulin
resistance and hyperinsulinemia"
Diabetes
drug can prevent heart disease, new study suggests - Science Daily, 3/25/12
- "one of the most common diabetes drugs,
metformin, also has a protective effect on the
heart ... metformin helps increase pumping capacity, improve energy balance,
reduce the accumulation of fat, and limit the loss of heart cells through
programmed cell death" - See
metformin at The Antiaging Store.
Low Levels of LDL
Cholesterol Predate Cancer Cases - Medscape, 3/25/12 -
"there is nothing here to suggest that statins would be
unsafe"
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.

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"
Bald-breaker! - The Daily, 3/22/12 - "the protein
prostaglandin D2 was found at triple the level in the bald patches of skin in
both men and male mice ... when added to a single hair in a lab dish, the
protein bound itself to the hair’s cells and stunted its growth ... Over the
next two years, there’ll very likely be a product based on prostaglandins to
treat hair loss"
Asthma: Low Vitamin D
Linked to High IgE, Need for Steroids - Medscape, 3/22/12 -
"We suggest that supplementation with
vitamin D should be done in patients with
asthma, both adults and children, to lower
steroid requirement and improve steroid response" - See

Bottled water may boost kids' tooth decay, dentists say - MSNBC, 3/20/12 -
"the practice of skipping tap water in favor of bottled
water may be contributing to rising rates of tooth
decay in young children ... You should brush twice a day with a fluoride
toothpaste ... bottled water may not have a sufficient amount of fluoride, which
is important for preventing tooth decay and promoting oral health" - See

Daily Aspirin May Help Prevent and Treat Cancer - WebMD, 3/20/12 -
"analyzed data from 51 trials originally designed to
examine the impact of daily aspirin on heart
attack and stroke risk ... taking a low-dose aspirin every day reduced the risk
of death from cancer by 37% after at least five
years of use ... In a second study, the researchers examined the impact of daily
aspirin therapy on cancer metastasis, or spread, by analyzing newly published
data from five other large trials ... Over an average follow-up of
six-and-a-half years, daily aspirin use was associated with a 36% reduced risk
of cancer with distant spread"
Feeding
your baby on demand 'may contribute to higher IQ' - Science Daily, 3/20/12 -
"demand-feeding is associated with higher IQ scores at
age eight, and this difference is also evident in the results of SATs tests at
ages five, seven, 11 and 14 ... The difference in IQ levels of around four to
five points, though statistically highly significant, would not make a child at
the bottom of the class move to the top, but it would be noticeable"
Bisphenol A (BPA) could affect reproductive capabilities, cause infection of the
uterus - Science Daily, 3/20/12 - "in addition to
affecting the heart, brain and nervous system, bisphenol
A (BPA), could affect a mammal's ability to reproduce by altering the
structure of the uterus in ways that can progress to a potentially fatal
infection ... These results suggest that BPA enhances the immune responsiveness
of the uterus and that the heightened responsiveness in the C57BL/6 strain of
females is related to increased susceptibility to pyometra"

Protection
of LDL from oxidation by olive oil polyphenols is associated with a
downregulation of CD40-ligand expression and its downstream products in vivo in
humans - Am J Clin Nutr. 2012 Mar 21 - "Polyphenols
could exert health benefits not only by scavenging free radicals but also by
modulating gene expression ... a randomized, crossover, controlled trial, 18
healthy European volunteers daily received 25 mL olive oil with a low polyphenol
content (LPC: 2.7 mg/kg) or a high polyphenol content (HPC: 366 mg/kg) in
intervention periods of 3 wk separated by 2-wk washout periods ... In addition
to reducing LDL oxidation, the intake of
polyphenol-rich olive oil reduces CD40L gene expression, its downstream
products, and related genes involved in atherogenic and inflammatory processes
in vivo in humans. These findings provide evidence that polyphenol-rich olive
oil can act through molecular mechanisms to provide cardiovascular health
benefits" - See

25-Hydroxyvitamin D Is Associated with Increased Risk of the Development of the
Metabolic Syndrome at Five Years: Results from a National, Population-Based
Prospective Study - J Clin Endocrinol Metab. 2012 Mar 22 -
"metabolic syndrome (MetS)
... waist circumference (WC) ... Compared with
those in the highest quintile of 25(OH)D (≥34
ng/ml), MetS risk was significantly higher in people with 25(OH)D in the first
(<18 ng/ml) and second (18-23 ng/ml) quintiles; odds ratio (95% confidence
interval) = 1.41 (1.02-1.95) and 1.74 (1.28-2.37), respectively. Serum 25(OH)D
was inversely associated with 5-yr WC (P < 0.001), triglycerides (P < 0.01),
fasting glucose (P < 0.01), and homeostasis model assessment for insulin
resistance (P < 0.001) but not with 2-h plasma glucose (P = 0.29), high-density
lipoprotein cholesterol (P = 0.70), or blood pressure (P = 0.46).Conclusions:In
Australian adults, lower 25(OH)D concentrations were associated with increased
MetS risk and higher WC, serum triglyceride, fasting glucose, and insulin

A
Combination of High-dose Vitamin C Plus Zinc for the Common Cold - J Int Med
Res. 2012;40(1):28-42 - "Vitamin C and zinc play
important roles in nutrition, immune defence and maintenance of health. Intake
of both is often inadequate, even in affluent populations ... After an overview
of the literature on the effects of the separate administration of either
vitamin C or zinc against the common cold, this article presents data from two
preliminary, double-blind, randomized, placebo-controlled trials, conducted with
a combination of 1000 mg vitamin C plus 10 mg zinc in patients with the common
cold. In both studies, a nonsignificant reduction of rhinorrhoea duration (range
9 - 27%) was seen. In pooled analyses of both studies (n = 94), vitamin C plus
zinc was significantly more efficient than placebo at reducing rhinorrhoea over
5 days of treatment. Furthermore, symptom relief was quicker and the product was
well tolerated"

Scientists pinpoint how vitamin D may help clear amyloid plaques found in
Alzheimer's - Science Daily, 3/6/12 - "vitamin D3
may activate key genes and cellular signaling networks to help stimulate the
immune system to clear the amyloid-beta protein ... in both Type I and Type II
macrophages, the added 1a,25-dihydroxyvitamin D3 played a key role in opening a
specific chloride channel called "chloride channel 3 (CLC3)," which is important
in supporting the uptake of amyloid beta through the process known as
phagocytosis. Curcuminoids activated this chloride channel only in Type I
macrophages ... The scientists also found that 1a,25-dihydroxyvitamin D3
strongly helped trigger the genetic transcription of the chloride channel and
the receptor for 1a,25-dihydroxyvitamin D3 in Type II macrophages" - See

Omega-3 Fatty Acids Help Brain Age Better - WebMD, 2/27/12 -
"the results suggest diets lacking in omega-3 fatty
acids may cause the brain to age faster ... people whose DHA levels were in the
bottom 25% of the group had lower brain volumes compared with people with higher
DHA levels ... In addition, people with both low DHA and all the other omega-3
fatty acid levels scored lower on tests of visual memory, processing, and
abstract thinking ... Researchers say the results suggest that low DHA and other
omega-3 fatty acid levels are associated with a pattern of memory and brain
function problems even in people free of dementia" - See

magnetic resonance screening (MRI) ... researchers compared the brain scans and
diets of 966 adults with an average age of 72 ... those who most closely
followed a Mediterranean diet had a lower measure of WMHV than those who did
not. Each increase in the Mediterranean diet score was associated with a
corresponding decrease in white matter hyperintensity volume score ... the

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 ... Consumers should be taking a full spectrum vitamin E

Antioxidant has potential in the Alzheimer's fight - Science Daily, 12/14/11
- "When you cut an apple and leave it out, it turns
brown. Squeeze the apple with lemon juice, an antioxidant, and the process slows
down ... Simply put, that same "browning" process-known as oxidative
stress-happens in the brain as Alzheimer's disease sets in ... an antioxidant
can delay the onset of all the indicators of Alzheimer's disease, including
cognitive decline. The researchers administered an antioxidant compound called
MitoQ to mice genetically engineered to develop Alzheimer's. The results of
their study were published in the Nov. 2 issue of the Journal of Neuroscience
... Oxidative stress is believed to cause neurons in the brain to die, resulting
in Alzheimer's ... The brain consumes 20 percent of the oxygen in the body even
though it only makes up 5 percent of the volume, so it's particularly
susceptible to oxidative stress ... MitoQ selectively accumulates in the
mitochondria" - Note: I couldn't find the ingredients but it sounds like

Eating
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
cortex volumes in relation to fish consumption reduced the risk for five-year
decline to MCI or Alzheimer's by almost five-fold ... Consuming baked or broiled
fish promotes stronger neurons in the brain's gray matter by making them larger

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

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

Low
vitamin B12 levels may lead to brain shrinkage, cognitive problems - Science
Daily, 9/26/11 - "Older people with low blood levels of
vitamin B12 markers may be more likely to have lower brain volumes and have
problems with their thinking skills ... An average of four-and-a-half years
later, MRI scans of the participants' brains were taken to measure total brain
volume and look for other signs of brain damage ... Having high levels of four
of five markers for vitamin B12 deficiency was associated with having lower
scores on the cognitive tests and smaller total brain volume ... On the
cognitive tests, the scores ranged from -2.18 to 1.42, with an average of 0.23.
For each increase of one micromole per liter of homocysteine -- one of the
markers of B12 deficiency -- the cognitive scores decreasedby 0.03 standardized

Natural
Alzheimer's-fighting compound created inexpensively in lab - Science Daily,
8/25/11 - "Until now, researchers have only been able to
derive small amounts of the compound directly from the Huperzia serrata plant,
or had to resort to lengthy and cumbersome methods to synthesize it in the lab
... Now researchers at Yale have developed a practical and cost-effective method
to synthesize huperzine A in the lab. The process requires just eight steps and
produces a yield of 40 percent. Previously, the best synthetic techniques had
required twice as many steps and achieved yields of only two percent ... In
addition, the Herzon lab and the firm are working with the U.S. Army, which is
interested in huperzine A's potential in blocking the effects of chemical
warfare agents ... Other Alzheimer's treatments based on enzyme inhibitors are
currently prescribed in the U.S., but huperzine A binds better, is more easily
absorbed by the body and last longer in the body than other treatments ... We
believe huperzine A has the potential to treat a range of neurologic disorders
more effectively than the current options available" - See

Treatment with vitamin C dissolves toxic protein aggregates in Alzheimer's
disease - Science Daily, 8/18/11 - "The brains of
people with Alzheimer's disease contain lumps of so-called amyloid plaques which
consist of misfolded protein aggregates. They cause nerve cell death in the
brain and the first nerves to be attacked are the ones in the brain's memory
centre ... When we treated brain tissue from mice suffering from Alzheimer's
disease with vitamin C, we could see that the toxic protein aggregates were
dissolved ... The notion that vitamin C can have a positive effect on
Alzheimer's disease is controversial, but our results open up new opportunities
for research into Alzheimer's and the possibilities offered by vitamin C"

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" -

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

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"

Docosahexaenoic Acid reduces amyloid {beta} production via multiple, pleiotropic
mechanism - J Biol Chem. 2011 Feb 15 - "Alzheimer's
disease (AD) is characterized by accumulation of the amyloidogenic peptide Aβ
generated by β- and γ-secretase processing of the amyloid precursor protein
(APP). The intake of the polyunsaturated fatty acid (PUFA) docosahexaenoic acid
(DHA) has been associated with decreased amyloid deposition and a reduced risk
in AD in several epidemiological trials; however the exact underlying molecular
mechanism remains to be elucidated ... DHA reduces amyloidogenic processing by
decreasing β- and γ-secretase activity, whereas the expression and protein
levels of BACE1 and Presenilin1 remain unchanged. In addition, DHA increases
protein stability of α-secretase resulting in increased non-amyloidogenic
processing. Beside the known effect of DHA to decrease cholesterol de novo
synthesis, we found cholesterol distribution in plasma membrane to be altered.
In presence of DHA, cholesterol shifts from raft to non-raft domains, which is
accompanied by a shift in γ-secretase activity and Presenilin1 protein level.
Taken together, DHA directs amyloidogenic processing of APP towards
non-amyloidogenic processing, effectively reducing Aβ release. DHA has a typical
pleiotropic effect; DHA-mediated Aβ reduction is not the consequence of a single
major mechanism, but the result of combined multiple effects" - See

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

Docosahexaenoic Acid Deficiency and Prefrontal Cortex Neuropathology in
Recurrent Affective Disorders - J Nutr. 2010 Feb 10 -
"Increasing evidence suggests that docosahexaenoic
acid [DHA, 22:6(n-3)], the principal (n-3) fatty acid in brain gray matter, has
neurotrophic and neuroprotective properties. Preliminary clinical evidence also
suggests that the perinatal accrual, and the subsequent dietary maintenance of,
cortical DHA is positively associated with cortical gray matter volumes. The
pathophysiology of recurrent affective disorders, including unipolar and bipolar
depression, is associated with (n-3) fatty acid deficiency, DHA deficits,
impaired astrocyte mediated vascular coupling, neuronal shrinkage, and
reductions in gray matter volume in the prefrontal cortex (PFC). Preclinical
studies have also observed neuronal shrinkage and indices of astrocyte pathology
in the DHA-deficient rat brain. Together, this body of evidence supports the
proposition that DHA deficiency increases vulnerability to neuronal atrophy in
the PFC of patients with affective disorders" - See

1α,25-dihydroxyvitamin D_{3} Interacts with Curcuminoids to Stimulate Amyloid-β
Clearance by Macrophages of Alzheimer's Disease Patient - J Alzheimers Dis.

"1,25D3 strongly stimulated Abeta phagocytosis and
clearance while protecting against apoptosis. Certain synthetic curcuminoids in
combination with 1,25D3 had additive effects on phagocytosis in Type I but not
Type II macrophages. In addition, we investigated the mechanisms of 1,25D3 and
curcuminoids in macrophages. The 1,25D3 genomic antagonist analog MK inhibited
1,25D3 but not curcuminoid effects, suggesting that 1,25D3 acts through the
genomic pathway. In silico, 1,25D3 showed preferential binding to the genomic
pocket of the vitamin D receptor, whereas bisdemethoxycurcumin showed preference
for the non-genomic pocket. 1,25D3 is a promising hormone for AD
immunoprophylaxis because in Type I macrophages combined treatment with 1,25D3

treatment is effective alone. Human macrophages are a new paradigm for testing

flavonoids or grape flavonoids reduces brain pathology and, in some cases,
improves cognition. Dr Williams and colleagues have focused their own cellular
studies on a flavonoid called epicatechin, which is abundant in a number of
foodstuffs, including cocoa ... epicatechin protects brain cells from damage but
through a mechanism unrelated to its antioxidant activity and shown in
laboratory tests that it can also reduce some aspects of Alzheimer’s disease

Vitamin
D, Curcumin May Help Clear Amyloid Plaques Found In Alzheimer's Disease -
Science Daily, 7/15/09 - "The team discovered that
curcuminoids enhanced the surface binding of amyloid beta to macrophages and
that vitamin D strongly stimulated the uptake and absorption of amyloid beta in
macrophages in a majority of patients ... Since vitamin D and curcumin work
differently with the immune system, we may find that a combination of the two or
each used alone may be more effective — depending on the individual patient"

"Alzheimer disease (AD) ... vascular
dementia (VaD) ... The pooled relative risks (RRs) of AD, VaD, and Any
dementia for light to moderate drinkers compared with nondrinkers were 0.72 (95%
CI = 0.61-0.86), 0.75 (95% CI = 0.57-0.98), and 0.74 (95% CI = 0.61-0.91),

Any dementia (RR = 0.53, 95% CI = 0.53-0.82) but not cognitive decline. There
were not enough data to examine VaD risk among "drinkers." Those classified as
heavy drinkers did not have an increased risk of Any dementia compared with
nondrinkers, but this may reflect sampling bias. Our results suggest that
alcohol drinkers in late life have reduced risk of dementia. It is unclear
whether this reflects selection effects in cohort studies commencing in late

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

"The new study looked at luteolin (LOO-tee-OH-lin), a plant flavonoid known
to impede the inflammatory response in several types of cells outside the

luteolin was shutting down production of a key cytokine in the inflammatory
pathway, interleukin-6 (IL-6). The effects of luteolin exposure were
dramatic, resulting in as much as a 90 percent drop in IL-6 production in
the LPS-treated cells ... Inflammatory cytokines such as interleukin-6 are
very well known to inhibit certain types of learning and memory that are

B-vitamins reduce plasma levels of beta amyloid - Neurobiol Aging. 2006
Nov 17 - "Elevated plasma homocysteine (tHcy) is a
risk factor for Alzheimer's disease (AD), and thus B vitamins may have a
role in the prevention of AD. The objective of this study was to determine
if tHcy lowering vitamins decrease the circulating levels of A-beta protein
1-40 (Abeta40). We randomized 299 older men to treatment with 2mg of folate,
plus 25mg of B6 and 400mug of B12, or placebo. After 2 years of treatment
the mean (S.E.) increase of Abeta40 was 7.0pg/ml (8.4) in the vitamin group

Disappointing Data Confound Claims For DHEA Effectiveness [against
Alzheimer's] - Psychiatric News, 6/6/03 -
"Twenty-eight patients were blindly chosen to receive 50 mg of
DHEA twice a day for six months ... The dose of DHEA, Wolkowtiz said,
was targeted to achieve blood levels of the hormone at or slightly above the
top of the normal range of DHEA levels found in healthy young adults ...
numerically, DHEA did have a benefit on cognitive ratings, but overall, on
the CIBIC-Plus, there was no significant benefit shown ... at three months,
the DHEA group, compared with placebo, showed a trend toward improvement on
the ADAS-Cog, but the improvement only narrowly missed being statistically
significant ... DHEA has been reported to reduce
cortisol, the so-called "stress hormone," which in response to stress is
released in large quantities that have been linked to neuronal stress and
damage" - Does anyone detect bias in that title? I don't know if
DHEA helps Alzheimer's or not but I feel the title should have been
something like "Alzheimer's Shows Trend Toward Improvement with DHEA at 3
Months". Their attitude seems to be that nothing works except what we write
prescriptions for. The way I understand it, Alzheimer's usually gets worse,
not better and cholinesterase inhibitors
slow the disease, they don't reverse it and three months is a short time to
determine if it is working. For example, see the following in the same

Diabetes
linked to cognitive impairment in older adults, study suggests - Science
Daily, 11/8/11 - "in older patients with diabetes, two
adhesion molecules -- sVCAM and sICAM -- cause inflammation in the brain,
triggering a series of events that affect blood vessels and, eventually, cause
brain tissue to atrophy. Importantly, they found that the gray matter in the
brain's frontal and temporal regions -- responsible for such critical functions
as decision-making, language, verbal memory and complex tasks -- is the area
most affected by these events ... at the age of 65, the average person's brain
shrinks about one percent a year, but in a diabetic patient, brain volume can be
lowered by as much as 15 percent ... Diabetes develops when glucose builds up in
the blood instead of entering the body's cells to be used as energy. Known as
hyperglycemia, this condition often goes hand-in-hand with inflammation ... Once
chronic inflammation sets in, blood vessels constrict, blood flow is reduced,
and brain tissue is damaged"

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"

to develop Alzheimer's disease prevented their brains from turning into a
neuronal wasteland ... he slowed the aging process in a mouse model for
Alzheimer's by lowering the activity of the IGF-1 signaling pathway ... mice
with reduced IGF-1 signaling live up to 35 percent longer than normal mice ...

statin drugs can have profoundly different effects on brain cells -both
beneficial and detrimental ... simvastatin reduced the expression of the
cholesterol transporter ABCA1 by approximately 80% in astrocytes, while
pravastatin lowered expression by only around 50%. Another interesting
difference was that while both statins decreased expression of the Tau protein
-associated with Alzheimer's disease -- in astrocytes, they increased Tau
expression in neurons; pravastatin also increased the expression of another
Alzheimer's hallmark, amyloid precursor protein (APP)"

study entry was associated with a 66% increase in Alzheimer's risk, while having
borderline high cholesterol raised the risk for vascular dementia by 52% ...
total cholesterol of 240 or higher is considered high, and a cholesterol of 200
to 239 is considered borderline high" - Maybe that's why most studies on
statins show that statins reduce the odds of having Alzheimer's. - Ben

Statin Drugs May Cut Dementia Risk - WebMD, 7/14/09 -
"people who took statin drugs were 58% less likely to
develop dementia than those who did not ... So what is going on? A risk factor
for dementia is high insulin; one theory is that statins may lower the high
insulin levels in the brain. Statins have also been shown to reduce levels of
C-reactive protein (CRP), a marker of inflammation that has been linked to the
pathology that can lead to dementia"

Inflammation May Trigger Alzheimer's Disease - Science Daily, 7/8/09 -
"Inflammation, which is part of the body's natural
immune response, occurs when the body activates white blood cells and produces
chemicals to fight infection and invading foreign substances ... We induced
inflammation in mice and found that it turned off the LRP pump that lets amyloid
beta protein exit the brain into the bloodstream. It also revved up an entrance
pump that transports amyloid beta into the brain. Both of these actions would
increase the amount of amyloid beta protein in the brain"

(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

Old
Gastrointestinal Drug Slows Aging, Researchers Say - Science Daily, 1/6/08 -
"Recent animal studies have shown that clioquinol – an
80-year old drug once used to treat diarrhea and other gastrointestinal
disorders – can reverse the progression of Alzheimer's, Parkinson's and
Huntington's diseases ... clioquinol acts directly on a protein called CLK-1,
often informally called "clock-1," and might slow down the aging process ...
Because clock-1 affects longevity in invertebrates and mice, and because we're
talking about three age-dependent neurodegenerative diseases, we hypothesize
that clioquinol affects them by slowing down the rate of aging ... clioquinol
was withdrawn from the market after being blamed for a devastating outbreak of
subacute myelo-optic neuropathy (SMON) in Japan in the 1960s. However, because
no rigorous scientific study was conducted at the time, and because clioquinol
was used safely by millions before and after the Japanese outbreak, some
researchers think its connection to SMON has yet to be proven" - I
Googled clioquinol and I don't think it's available anywhere.

Rosiglitazone reverses memory decline and hippocampal glucocorticoid receptor
down-regulation in an Alzheimer's disease mouse model - Biochem Biophys Res
Commun. 2008 Dec 22 - "An early down-regulation of GR,
not related to elevated plasma corticosterone levels, was found in different
hippocampal subfields of the transgenic mice and this decrease was prevented by
rosiglitazone. In parallel with behavioural studies, rosiglitazone also
normalized GR levels in older animals. This effect may contribute to explain the
attenuation of memory decline by PPARgamma activation in an AD mouse model"
- Note: That's another reason I take rosiglitazone's competitor,
pioglitazone which has
less chance of causing heart problems.

Rosiglitazone increases dendritic spine density and rescues spine loss caused by

rat neurons. This effect was abolished by the PPAR-gamma-specific antagonist,
GW9662, suggesting that rosiglitazone exerts this effect by activating the
PPAR-gamma pathway. Furthermore, the C-terminal-truncated fragment of apoE4
significantly decreased dendritic spine density. Rosiglitazone rescued this
detrimental effect. Thus, rosiglitazone might improve cognition in AD patients
by increasing dendritic spine density"
