35 year
study finds exercise reduces risk of dementia - Science Daily, 12/10/13 -
"The study identifies five healthy behaviors as being
integral to having the best chance of leading a disease-free lifestyle: taking
regular exercise, non-smoking, a low body weight,
a healthy diet and a low alcohol intake ... The people who consistently followed
four or five of these behaviors experienced a 60 per cent decline in
dementia and cognitive decline -- with exercise
being the strongest mitigating factor -- as well as 70 per cent fewer instances
of diabetes, heart disease and stroke, compared with people who followed none"
Smoking Pot May Double Risk
for Stillbirth - Medscape, 12/9/13 - "Odds of
stillbirth were nearly 2 times higher among women whose fetuses tested positive
for any drug metabolite (case patients, 7.0%; control patients, 3.7%; odds ratio
[OR], 1.94; 95% confidence interval [CI], 1.16 - 3.27). The most common illicit
drug was cannabis, which increased the odds of
stillbirth by more than twice as much (case patients, 3.9%; control patients,
1.7%; OR, 2.34; 95% CI, 1.13 - 4.81) ... There was a dose–response relationship
between maternal smoking and stillbirth, with
odds of stillbirth increasing with higher maternal cotinine levels. Exposure to
secondhand smoke (lack of maternal smoking history along with cotinine levels
less than 3 ng/mL) increased the odds of stillbirth by twice as much (case
patients, 5.0%; control patients, 2.7%; OR, 2.06; 95% CI, 1.24 - 3.41)"

Some Gut Bacteria May
Affect Colorectal Cancer Risk - Medscape, 12/6/13 -
"Because of the potentially modifiable nature of the
gut bacteria, our findings may have implications for CRC prevention ... The
researchers found decreased microbiome community diversity in patients with
CRC , compared with that of healthy participants(P
= .02). In an analysis by taxa, patients with CRC had lower relative abundances
of Clostridia, at 68.6% compared with 77.8% in people without CRC. In contrast,
patients with CRC carried a higher relative abundance of Fusobacterium (31.9% vs
11.7% for control patients) ... A higher relative abundance of Fusobacterium was
associated with increased CRC risk (multivariable odds ratio [OR], 4.11 ...
Actinobacteria Atopobium (OR, 14.36; 95% CI, 2.78 - 74.30; P < .001) and the
Bacteriodetes Porphyromonas (OR, 5.17; 95% CI, 1.75 - 15.25; P = .001) were also
associated with CRC risk" - See

Some Diabetes Drugs May Affect Cancer Risk in Women - WebMD, 12/6/13 -
"Cleveland Clinic researchers analyzed data from more
than 25,600 women and men with type 2 diabetes ... The drugs included "insulin
sensitizers," which lower blood sugar and insulin levels in the body by
increasing the muscle, fat and liver's response to insulin. The other drugs
analyzed were "insulin secretagogues," which lower blood sugar by stimulating
beta cells in the pancreas to make more insulin ... The use of insulin
sensitizers in women was associated with a 21 percent decreased cancer risk
compared to insulin secretagogues, the investigators found. Furthermore, the use
of a specific insulin sensitizer called
thiazolidinedione was
associated with a 32 percent decreased cancer risk in women compared to
sulphonylurea, an insulin secretagogue ... there were no significant differences
between men who used insulin sensitizers or secretagogues"

Probiotic therapy alleviates autism-like behaviors in mice - Science Daily,
12/5/13 - "the researchers treated the mice with
Bacteroides fragilis, a bacterium that has been used as an experimental
probiotic therapy in animal models of GI disorders
... The result? The leaky gut was corrected ... In addition, observations of the
treated mice showed that their behavior had changed. In particular, they were
more likely to communicate with other mice, had reduced anxiety, and were less
likely to engage in a repetitive digging behavior ... The B. fragilis treatment
alleviates GI problems in the mouse model and also improves some of the main
behavioral symptoms ... This suggests that GI problems could contribute to
particular symptoms in neurodevelopmental disorders"
A Low-Fat, Plant-Based
Lifestyle and Serum HDL Levels - Medscape, 12/4/13 -
"HDL levels decreased by 8.7% (p<0.001) despite
significant reductions (p<0.001) in BMI (-3.2%), systolic BP (-5.2%), diastolic
BP (-5.2%), triglycerides (TG; -7.7%), FPG (-6.3%), LDL (-13.0%), total
cholesterol (TC, -11.1%), TC: HDL ratio (-3.2%), and LDL: HDL ratio (-5.3%).
While 323 participants classified as having MetS
at program entry no longer had this status after the 30 days, 112 participants
acquired the MetS classification as a result of reduction in their HDL levels"
Omega-3
Dietary Supplements Pass Blood-Brain Barrier - Science Daily, 12/4/13 -
"omega-3 fatty acids
in dietary supplements can cross the blood brain barrier in people with
Alzheimer's disease ... The findings are
presented in the Journal of Internal Medicine, and strengthen the evidence that
omega-3 may benefit certain forms of this seriously debilitating disease ...
Thirty-three patients participated in the study, 18 of whom received a daily
omega-3 supplement and 15 a placebo for six months. The results show that the
first group had higher levels of both DHA and eicosapentaenoic acid (EPA,
another omega-3 fatty acid) in their cerebrospinal fluid (which surrounds the
CNS) and blood. No such change was seen in the placebo group ... Moreover, they
also found that levels of DHA correlated directly with the degree of change in
Alzheimer's disease and inflammatory markers in the cerebrospinal fluid"

Prenatal
exposure to alcohol disrupts brain circuitry: No safe level of drinking during
pregnancy, neuroscientist says - Science Daily, 12/4/13 -
"prenatal exposure to
alcohol significantly altered the expression of genes and the development of
a network of connections in the neocortex -- the part of the brain responsible
for high-level thought and cognition, vision, hearing, touch, balance, motor
skills, language, and emotion -- in a mouse model of FASD. Prenatal exposure
caused wrong areas of the brain to be connected with each other ... Although
this study uses a moderate- to high-dose model, others have shown that even
small doses alter development of key receptors in the brain ... Huffman's team
found dramatic changes in intraneocortical connections between the frontal,
somatosensory and visual cortex in mice born to mothers who consumed ethanol
during pregnancy. The changes were especially
severe in the frontal cortex, which regulates motor skill learning,
decision-making, planning, judgment, attention, risk-taking, executive function
and sociality"

Vegetable,
fruit and nitrate intake in relation to the risk of Barrett's oesophagus in a
large Dutch cohort - Br J Nutr. 2013 Dec 5:1-11 -
"The Netherlands Cohort Study recruited 120 852 individuals aged 55-69 years in
1986. Vegetable and fruit intake was assessed
using a 150-item FFQ, and nitrate intake from dietary sources and drinking water
was determined ... 16.3 years of follow-up ... Men exhibited a lower risk of
Barrett's oesophagus in the highest v. the lowest quintile of total
(multivariable-adjusted hazard ratio (HR): 0.66, 95 % CI 0.43, 1.01), raw (HR
0.63, 95 % CI 0.40, 0.99), raw leafy (HR 0.55, 95 % CI 0.36, 0.86) and Brassica
(HR 0.64, 95 % CI 0.41, 1.00) vegetable intake. No association was found for
other vegetable groups and fruits. No significant associations were found
between vegetable and fruit intake and Barrett's oesophagus risk among women.
Total nitrate intake was inversely associated with Barrett's disease risk in men
(HR 0.50, 95 % CI 0.25, 0.99) and positively associated with it in women (HR
3.77, 95 % CI 1.68, 8.45) (P for interaction = 0.04)"

"One hundred and twenty patients with NAFLD and 120
age-, sex- and BMI-matched patients with non-NAFLD were enrolled into a
case-control study ... Serum SHBG levels were
significantly lower in
NAFLD group than in non-NAFLD group (24.5 ±
11.0 vs 37.6 ± 14.4 nm, P < 0.001)" - Note: Everything I've read is
that more people are worried about high SHBG than low but I'm not a doctor.
Oral
Bisphenol A (BPA) given to rats at moderate doses is associated with erectile
dysfunction, cavernosal lipofibrosis and alterations of global gene
transcription - Int J Impot Res. 2013 Dec 5 - "In
all, 2.5-month-old rats were given drinking water daily without and with BPA at
1 and 0.1 mg kg-1 per day ... Orally administered BPA did not affect body
weight, but (1) decreased serum T and E2; (2) reduced the EFS response and
increased the drop rate; (3) increased within the corporal tissue the presence
of fat, myofibroblasts and apoptosis; (4) lowered the contents of SM and stem
cells, but not nerve terminals; and (5) caused alterations in the
transcriptional profiles for both mRNA and miRs within the penile shaft.
Long-term exposure of rats to oral BPA caused a moderate corporal veno-occlusive
dysfunction (CVOD), possibly due to alterations within the corporal tissue that
pose gene transcriptional changes related to inflammation, fibrosis and
epithelial/mesenchymal transition (EMT)"
Lowered
Cancer Risk With ACE Inhibitors/ARBs: A Population-Based Cohort Study - J
Clin Hypertens (Greenwich). 2013 Nov 8 - "Using the
Taiwan National Health Insurance Research Database, 297,688 eligible study
patients with essential hypertension were identified. According to their
antihypertensive prescriptions, the study patients were stratified into an
ACE inhibitor group,
an ARB group, or a control group
... In the ACE inhibitor group compared with the control group, the hazard ratio
was 0.51 (95% confidence interval, 0.39-0.68). In the ARB group compared with
the control group, the hazard ratio was 0.8 (95% confidence interval,
0.65-0.97). Regular use of ACE inhibitors/ARBs was not associated with an
increased risk of
cancer development and was actually found to
decrease overall cancer risk in this study"

Effect of
Lactobacillus rhamnosus CGMCC1.3724 supplementation on weight loss and
maintenance in obese men and women - Br J Nutr. 2013 Dec 3:1-13 -
"The present study investigated the impact of a
Lactobacillus rhamnosus CGMCC1.3724 (LPR)
supplementation on weight loss and
maintenance in obese men and women over 24 weeks ... The intention-to-treat
analysis showed that after the first 12 weeks and after 24 weeks, mean weight
loss was not significantly different between the LPR and placebo groups when all
the subjects were considered. However, a significant treatment × sex interaction
was observed. The mean weight loss in women in the LPR group was significantly
higher than that in women in the placebo group (P= 0.02) after the first 12
weeks, whereas it was similar in men in the two groups (P= 0.53). Women in the
LPR group continued to lose body weight and fat mass during the
weight-maintenance period, whereas opposite changes were observed in the placebo
group. Changes in body weight and fat mass during the weight-maintenance period
were similar in men in both the groups. LPR-induced weight loss in women was
associated not only with significant reductions in fat mass and circulating
leptin concentrations but also with the relative abundance of bacteria of the
Lachnospiraceae family in faeces. The present study shows that the Lactobacillus
rhamnosus CGMCC1.3724 formulation helps obese women to achieve sustainable
weight loss" - See

Therapeutic
Potential of Turmeric in Alzheimer's Disease: Curcumin or Curcuminoids? -
Phytother Res. 2013 Jul 19 - "Alzheimer's disease (AD)
is the most common form of dementia. There is limited choice in modern
therapeutics, and drugs available have limited success with multiple side
effects in addition to high cost. Hence, newer and alternate treatment options
are being explored for effective and safer therapeutic targets to address AD.
Turmeric possesses multiple medicinal uses including treatment for AD.
Curcuminoids, a mixture of curcumin, demethoxycurcumin, and
bisdemethoxycurcumin, are vital constituents of turmeric. It is generally
believed that curcumin is the most important constituent of the curcuminoid
mixture that contributes to the pharmacological profile of parent curcuminoid
mixture or turmeric. A careful literature study reveals that the other two
constituents of the curcuminoid mixture also contribute significantly to the
effectiveness of curcuminoids in AD. Therefore, it is emphasized in this review

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

the nerve cells to malfunction and eventually die ... The team formed amyloid

closer to that of the mice with no mutations than to their own initial
pathological state. From this we can say that the disease has significantly
regressed ... The results, which were published in the journal Neurobiology of

Biosynthetic grape-derived compound prevents progression of Alzheimer’s disease
in animal model - Science Daily, 5/1/12 -
"Polyphenols, which occur naturally in grapes, fruits, and vegetables, have been
shown to prevent the cognitive decline associated with AD in a mouse model, but
the molecules are very complex and are extensively metabolized in the body. This
is the first study to determine which specific subfraction of these molecules
penetrates the animal brain, and demonstrate that a drug compound similar to
polyphenols can exert similar bioactivities ... Dr. Pasinetti's team analyzed
the structure of this polyphenol by nuclear magnetic resonance imaging and
recreated it biosynthetically in the laboratory. Dr. Pasinetti and his
collaborators discovered that the synthetic polyphenol generated in the
laboratory also promoted plasticity and benefits in learning and memory
functions in the brains of the mice" - Note: Sounds like a way to get

Eating
fish, chicken, nuts may lower risk of Alzheimer's disease - Science Daily,
5/2/12 - "A new study suggests that eating foods that
contain omega-3 fatty acids, such as fish, chicken, salad dressing and nuts, may
be associated with lower blood levels of a protein related to Alzheimer's
disease and memory problems ... 1,219 people older than age 65, free of
dementia, provided information about their diet for an average of 1.2 years
before their blood was tested for the beta-amyloid. Researchers looked
specifically at 10 nutrients, including saturated fatty acids, omega-3 and
omega-6 polyunsaturated fatty acids, mono-unsaturated fatty acid, vitamin E,
vitamin C, beta-carotene, vitamin B12, folate and vitamin D ... the more omega-3
fatty acids a person took in, the lower their blood beta-amyloid levels.
Consuming one gram of omega-3 per day (equal to approximately half a fillet of
salmon per week) more than the average omega-3 consumed by people in the study
is associated with 20 to 30 percent lower blood beta-amyloid levels ... Other
nutrients were not associated with plasma beta-amyloid levels" - 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
... A recent placebo-controlled clinical trial in patients with amnestic mild
cognitive impairment (MCI) showed that long-term lithium treatment may actually
slow the progression of cognitive and functional deficits, and also attenuate
Tau hyperphosphorylation in the MCI-AD continuum"

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

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

dysregulates glucose uptake and other functions in brain areas affected by
Alzheimer disease. Insulin resistance may play a role in Alzheimer disease
etiopathogenesis. This longitudinal study examined whether insulin resistance
among late middle-aged, cognitively healthy individuals was associated with 1)
less gray matter in Alzheimer disease-sensitive brain regions and 2) worse
cognitive performance ... higher insulin resistance was related to medial
temporal lobe atrophy. Atrophy itself corresponded to cognitive deficits in the
RAVLT. Temporal lobe atrophy that was predicted by higher insulin resistance
significantly mediated worse RAVLT encoding performance ... These results
suggest that insulin resistance in an asymptomatic, late middle-aged cohort is
associated with progressive atrophy in regions affected by early Alzheimer
disease. Insulin resistance may also affect the ability to encode episodic

those prescribed other antihypertensive agents ... until now, the mechanism for
the apparent protective effect of ARBs on the brain was unclear ... Compared
with use of other antihypertensive medications, use of ARBs was associated with
a 32% to 35% lower likelihood of AD diagnosis, depending on the criteria used.
This was also true when the researchers compared patients treated with ARBs vs
untreated patients ... Patients treated with ARBs, with or without a diagnosis
of AD, also had significantly less amyloid deposition than untreated patients
and those treated with non-ARB antihypertensive medications" - See

Even in normal range, high blood sugar linked to brain shrinkage - Science
Daily, 9/3/12 - "The study involved 249 people age 60 to
64 who had blood sugar in the normal range as defined by the World Health
Organization. The participants had brain scans at the start of the study and
again an average of four years later ... Those with higher fasting blood sugar
levels within the normal range and below 6.1 mmol/l (or 110 mg/dL) were more
likely to have a loss of brain volume in the areas of the hippocampus and the
amygdala, areas that are involved in memory and cognitive skills, than those
with lower blood sugar levels. A fasting blood sugar level of 10.0 mmol/l (180
mg/dL) or higher was defined as diabetes and a level of 6.1 mmol/l (110 mg/dL)
was considered impaired, or prediabetes ... blood sugar on the high end of
normal accounted for six to 10 percent of the brain shrinkage"

Brain
insulin resistance contributes to cognitive decline in Alzheimer's disease -
Science Daily, 3/23/12 - "This is the first study to
directly demonstrate that insulin resistance occurs in the brains of people with
Alzheimer's disease ... Our research clearly shows that the brain's ability to
respond to insulin, which is important for normal brain function, is going
offline at some point ... We believe that brain insulin resistance may be an
important contributor to the cognitive decline associated with Alzheimer's
disease ... The risk of developing Alzheimer's disease is increased by 50
percent in people with diabetes ... insulin resistance of the brain occurs in
Alzheimer's disease independent of whether someone has diabetes ... The
investigators used samples of postmortem brain tissue from non-diabetics who had
died with Alzheimer's disease, stimulated the tissue with insulin, and measured
how much the insulin activated various proteins in the insulin-signaling
pathways ... three insulin-sensitizing medicines are already approved by the FDA
for treatment of diabetes. These drugs readily cross the blood-brain barrier and
may have therapeutic potential to correct insulin resistance in Alzheimer's
disease and MCI" - Note: I suspected this for a long time. It doesn't
say what those three drugs are but I'm guessing
metformin and
Actos are two of them. I
don't have diabetes but I take low doses of both. My doc says I'm crazy. See

Flu may boost Alzheimer's risk, research suggests - MSNBC, 2/16/12 -
"Viruses such as influenza and herpes may leave brain
cells vulnerable to degeneration later in life, and increase the risk of

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"

the cholesterol levels were tested for 2,587 people age 40 to 79 who had no
signs of Alzheimer's disease. Then they examined 147 autopsied people who died
after a long observation period (10 to 15 years) ... People with high
cholesterol levels, defined by a reading of more than 5.8 mmol/L, had
significantly more brain plaques when compared to those with normal or lower
cholesterol levels. A total of 86 percent of people with high cholesterol had
brain plaques, compared with only 62 percent of people with low cholesterol
levels ... insulin resistance, a sign of diabetes, may be another risk factor
for brain plaques associated with Alzheimer's disease"

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"

Hemoglobin
level in older persons and incident Alzheimer disease: Prospective cohort
analysis - Neurology. 2011 Jul 13 - "When compared
to participants with clinically normal hemoglobin (n = 717), participants with

1.02-2.52), as did participants with clinically high hemoglobin (n = 10, HR
3.39, 95% CI 1.25-9.20). Linear mixed-effects models showed that lower and
higher hemoglobin levels were associated with a greater rate of global cognitive
decline (parameter estimate for quadratic of hemoglobin = -0.008, SE -0.002, p <
0.001). Compared to participants with clinically normal hemoglobin, participants
with anemia had a -0.061 z score unit annual decline in global cognitive
function (SE 0.012, p < 0.001), as did participants with clinically high
hemoglobin (-0.090 unit/year, SE 0.038, p = 0.018) ... In older persons without

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"

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"

individuals with hearing loss, or those with cognitive impairment may be
overdiagnosed with hearing loss. The two conditions may share an underlying
neuropathologic process. "Finally, hearing loss may be causually related to
dementia, possibly through exhaustion of cognitive reserve, social isolation,
environmental deafferentation [elimination of sensory nerve fibers] or a
combination of these pathways.""

pravastatin lowered expression by only around 50%. Another interesting
difference was that while both statins decreased expression of the Tau protein

Old
Gastrointestinal Drug Slows Aging, Researchers Say - Science Daily, 1/6/08 -
"Recent animal studies have shown that clioquinol – an

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

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"

pioglitazone which has
less chance of causing heart problems.

Rosiglitazone increases dendritic spine density and rescues spine loss caused by
apolipoprotein E4 in primary cortical neurons - Proc Natl Acad Sci U S A.
2008 Jan 22 - "rosiglitazone significantly increased
dendritic spine density in a dose-dependent manner in cultured primary cortical
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"

risperidone, she reported, robustly increased acetylcholine release in
the cortex, while ziprasidone
only moderately increased levels, compared with
haloperidol and thioridazine,

- Psychiatric Times, 3/21/03 - "The
CYP46 enzyme regulates levels of brain cholesterol ... a change of just
one base in the CYP46 gene from cytosine (C) to thymine (T)—leads to a
decrease in functioning of CYP46, causing
cholesterol levels in the brain and cerebrospinal fluid to reach
higher-than-normal levels ... other research has shown that depletion of
brain cholesterol leads to a reduction in Aß ... The results, he wrote,
"suggest the possibility that LOAD [late onset Alzheimer's disease], the
most common degenerative disease of the brain, is a general end point for
abnormalities that increase the amount of cholesterol in the central nervous
system. If so, inhibiting cholesterol metabolism in the brain might
represent a viable treatment for LOAD.""
