... at the moment,
the best advice for preventing dementia is to eat a heart-healthy
diet and stay mentally and physically active.

Alzheimers. Newsweek. June 18, 2007: 61.
Regular exercise builds up the bodys levels of
BDNF (brain-derived neurotrophic factor) a Miracle-Gro
for the brain that is critical for learning, memory
and many other processes of higher thought. Carmichael,
Mary. Stronger, Faster, Smarter. Newsweek.

Early studies suggest that people who exercise at least
a few times a week tend to develop Alzheimers less often
and later than their more sedentary counterparts.

For the first time, scientists have coaxed the human
brain into growing new nerve cells simply by putting
subjects on a three-month aerobic-workout regimen.

In the Framingham Heart Study, which tracked nearly
900 healthy older men and women living in the Boston suburb
for roughly nine years, people with the highest blood levels
of DHA (Docosahexaenoic acid) they ate about three
servings of fish per week had about half the risk of
dementia compared to those with lower levels.

We saw a doubling of the risk of Alzheimers disease
among those who ate the most saturated fat versus those who
ate the least, says Chicago Health and Aging Project
researcher Martha Clare Morris. (Those who ate the most
sat fat averaged 25 grams a day, while those who ate the least
averaged half that much.) Nutrition Action Health

People who averaged roughly three servings a day of
vegetables had a 40 percent slower rate of cognitive decline
than those who ate roughly one serving a day. Nutrition

Keeping your mind active and your memory sharp is a
key part of aging well and enjoying better quality of life
as you grow older. The good news is that by challenging
and engaging your brain, and by continuing to learn throughout
your life, you can help maintain your healthy brain.
In fact, simple activities like attempting (and maybe even
finishing!) the daily crossword puzzle,
can make a
world of difference. AARPs Staying Sharp
Program. 2007. AARP. 13 July 2007.
There are many expensive techniques on the market that
offer to strengthen the mind, but most have not been empirically
proven to work. Vedantam, Shankar. Put
Your Mind to It. Washington Post. 2 Jan.
2007.
Participation in leisure activities is associated with
a reduced risk of development of dementia, both Alzheimers
disease and vascular dementia. The reduction in risk
is related to the frequency of participation. According
to our models, for example, elderly persons who did crossword
puzzles four days a week (four activity-days) had a risk of
dementia that was 47 percent lower than that among subjects
who did puzzles once a week (one activity-day).

Beyond middle age, people worry about their mental sharpness
getting rusty. This study (The Advanced
Cognitive Training for Independent and Vital Elderly - ACTIVE)
offers hope that cognitive training may be useful.

Institute on Agings Behavioral and Social Research Program,
which sponsored the work. ACTIVE has shown that
relatively brief targeted cognitive exercises can produce
durable changes in the skills taught. Sciencedaily.com.
Mental Exercise Helps Maintain Some Senior Thinking
Skills. 20 Dec 2006
Studies show that one of the best things you can do
for memory improvement is physical exercise.
researchers
have found that exercise can increase your brainpower, help
put off normal aging-related memory loss and, perhaps, even
prevent dementia and Alzheimers disease.
MayoClinic.com. Memory Improvement: Exercise Keeps Your
Mind Sharp. 30 April 2007.
Exercise increases blood flow to your whole body, including
your brain. And exercise seems to slow the loss of brain
tissue that typically begins in your 40s. Studies have
found that exercise seems to delay or sometimes prevent these
specific aging-related changes in your brain. And in
some cases, exercise may even provide memory improvement.
