Age of Information Overload
Whence the brain drain? Some
researchers believe our brains are overtaxed today. Not many would
disagree that we`ve moved beyond the Information Age into the "Age of
Information Overload." It`s believed that our cognitive processing, and
maybe even our memory storage capacity itself, can become overburdened as we age.
To
one extent or another, there`s little doubt that all of us are
bombarded by work and personal e-mail, Internet spam and junk mail,
faxes, magazines, 24-hour news, digital pages, telemarketer calls, cell
phone voice-mail and even the arcane logistics of play-date scheduling
for the kids after school!
Cognition is sensitive to a wide
variety of nutritional factors, and modern nutritional science is
uncovering that we can improve our mental powers effectively, and even
powerfully, through a wide array of nutrients and supplements, including
antioxidants, herbs, fats and other targeted dietary supplements.
A November 2008 review in the Journal of the American Nutraceutical Association pointed to benefits of a variety of bioactive nutritional supplement
ingredients (often called nutraceuticals), some of which we will look
at, in slowing age-associated memory impairment. Vinpocetine and
acetyl-L-carnitine were especially effective, followed by huperzine A;
rhodiola; ginseng and alpha lipoic acid. The least effective compounds
were the drugs, Aricept and Nemanda.
The brain train - vitamins to the rescue
Vitamin C.
To test whether vitamin C protects against mental decline, called
"cognitive impairment" in this study, researchers from Australia`s
University of Sydney looked at 117 elderly people in a retirement
community over a four-year period --- those who took vitamin C
supplements and those who did not. Seniors who took vitamin C
supplements experienced a lower incidence of severe cognitive decline.
The authors concluded that, "Vitamin C might protect against cognitive
impairment."
Vitamin E. Research from Italy and the U.S.
has shed new light on vitamin E`s role in brain health. A July 2005
study by Italian researchers from Perugia`s Institute of Gerontology and
Geriatrics (the InCHIANTI study) included 1,033 participants aged 65
and older. The research group found that people with the lowest blood
levels of vitamin E had the highest incidence of senile dementia and
"cognitive impairment" compared to those who had the highest vitamin E
levels.
Another 2005 study, this out of Chicago`s Rush Institute
for Healthy Aging, studied 6158 people 65 years of age or older between
1993 and 2002, including a subset of 1,041 patients who were clinically
evaluated. The researchers, led by Martha C. Morris, Sc.D., found that
higher intakes of vitamin E were associated with a reduced incidence of
Alzheimer`s disease.
Other recent studies have looked at different combinations of vitamins and minerals, with vitamins C and E as a foundation.
ALA anyone?
Alpha
lipoic acid is a very powerful brain-friendly antioxidant that has been
found to directly restore vitamin C and glutathione to their active
forms (after they have been used up) and to indirectly restore vitamin E
to its powerful form, as well.
In animals, alpha lipoic acid
protects brains cells against beta amyloid plaque, the buildup of which
is associated with dementia and Alzheimer`s disease. In fact, animal
studies published in 2002 and 2003 showed that treatment with alpha
lipoic acid prevented or reversed cognitive impairment similar to
dementia in humans.
In 2001, researchers gave nine patients with
Alzheimer`s disease 600 mg each day of ALA in addition to Aricept or
Exelon for an average of one year. This was the first such study to find
that treatment with alpha lipoic acid may be "neuroprotective" against
Alzheimer`s disease and related dementias.
In a 2007 follow-up,
43 ALA-supplemented patients were observed for a period of up to 48
months. In patients with mild dementia, the disease progressed extremely
slowly; in patients with moderate dementia, dementia progressed twice
as slowly.
B is for brain
In the American Journal of Geriatric Psychiatry,
researchers looked at 69 people with Alzheimer`s disease, including 33
patients who were taking a multivitamin supplement of folic acid,
vitamin B6 and vitamin B12.
In the 66 patients who were available
for the eight-week follow-up, the high-dose B-vitamin supplement
significantly reduced levels of homocysteine, which is important since
high levels of homocysteine may be associated with the breakdown of the
myelin sheaths that encase nerves and may be partly responsible for the
symptoms of Alzheimer`s-like dementia.
Botanical brain boosters
Ginkgo. Since stress in humans is associated with decreased memory and learning function, Polish scientists gave an extract of Ginkgo biloba
(EGb 761 or Ginkgold) to rats that had been chronically stressed.
According to their study, the supplement improved memory and cognition
in all rats, including those that had been stressed.
The last 30
years have yielded a large body of evidence supportive of ginkgo
supplementation for brain-boosting, although some studies have studied
the wrong groups, have looked for the wrong results or have used too low
a dose. According to 2000 review by New York University`s P.L. LeBars,
daily dosages of 240 mg a day appeared to demonstrate the most benefit
in patients with memory disorders or dementia.
Ginseng. In
2008, a group of South Korean researchers published the results of an
open-label study in which patients with Alzheimer`s disease received
Panax ginseng extract or a placebo for 12 weeks. In the
ginseng-supplemented group, all main measures cognitive performance
began to show improvements and continued for up to 12 weeks. After
discontinuing ginseng, the improved scores declined to the levels of the
control group. According to the authors, "These results suggest that
Panax ginseng is clinically effective in the cognitive performance of
[Alzheimer`s disease] patients."
Pomegranate. A 2005
rodent study found that drinking pomegranate juice during pregnancy may
lower the risk of hypoxia ischemia-related brain injuries (a condition
caused by decreased blood flow and oxygen to the fetal brain) in babies.
The authors said their results "demonstrate that maternal dietary
supplementation with pomegranate juice is neuroprotective for the
neonatal brain."
A more recent study in newborn mice, published
in 2007, suggest that special compounds in pomegranate, polyphenols,
should be further investigated as a potential treatment to decrease
brain injury due to neonatal hypoxia-ischemia.
Vinpocetine. Vinpocetine is a supplement that`s derived from vincamine, an extract of the periwinkle plant (Vinca minor).
Widely used and studied in Europe for over 25 years, awareness of this
product and the research behind is now starting to come into its own.
A 2001 review (meta-analysis) in the Journal of the American Nutraceutical Association
by the University of Miami`s Bernd Wollschlaeger, M.D., winnowed down
39 vinpocetine studies involving 1,912 subjects into three studies -
from 1986 through 1991 - involving a total of 174 patients treated with
vinpocetine and 114 given a placebo.
According to Wollschlaeger,
all three studies "suggest a significant [mental] improvement in the
cognitive function of patients suffering from dementia or other symptoms
of cerebrovascular diseases." Based on several mental-performance
tests, the significant improvement in cognitive function, in these three
studies, says Wollschlaeger, "suggest[s] a clinical application of
vinpocetine in the early phases of mild cognitive impairment" before
full-blown "senile dementia" or Alzheimer`s disease start to develop.
"Designer" supplements for brain support
Acetyl-L-carnitine (ALC).
A 2004 review of 21 double-blind, placebo-controlled studies using
acetyl-L-carnitine in the treatment of "mild cognitive impairment" and
mild Alzheimer`s disease showed significant improvements versus the
placebo or "dummy" pills.
CDP-choline. A relative of
phosphatidylserine (PS), cytidine-5-diphosphocholine, or CDP-choline,
has been attracting some recent research interest. In 2005, scientists
from the Massachusetts Institute of Technology (MIT) found, in an animal
study, that long-term supplementation with CDP-choline may hold back
memory impairment.
Huperzine A. Huperzine A is a purified substance derived from Chinese club moss (Huperzia serrata).
A 2005 paper on this supplement speculated that the beneficial effects
in Alzheimer`s disease are probably due to several cell- and
neuro-protective effects operating at the same time.
Food-based mental mojo?
In
a 2004 observational study from the U.K. looking at dietary supplement
use, people born in 1936 received mental ability testing in 1947 and
later in 2000-2001. At age 64, cognitive function was better in dietary
supplement users than in non-users, especially in those people who were
also taking marine oil supplements.
Quality of mind = quality of life
Many
would argue that quality of mind - a well functioning brain - is truly
at the elemental core of quality of life; therefore, ways in which we
can improve our mental abilities and functions, and fend off the memory
and general cognitive declines associated with aging, should be more
than welcome - especially when these ways are holistic,
supplement-based, and without the profound unwanted side effects often
associated with synthetic pharmaceutical drugs.
The key to high performance is proper nutrition. As a former long-distance runner, I know first hand what can happen when a person does not properly nutriate. At the age of 32, I was diagnosed with osteoporosis. When you're burning fuel and not putting anything in the tank, your engine dies. According to Dr. Joel Wallach, more than 100,000 athletes die every year as a result of vitamin and mineral deficiency. I am writing this blog to prevent what happened to me from happening to you.
