Train your brain for a

If you thought you had no authority over the
body's commander in chief, think again. Here are five effective activities and
guidelines for brain health, with particular attention on how to sharpen and
Do the crossword puzzle -- unless you're good at it
If you've searched the Web for memory-boosting exercises, you may have been
urged to play sudoku, take up an instrument, try a brain-teasing video game, or
challenge someone to a chess match. However, none will do your brain much good
unless the activity is both new to you and difficult. "For good brain health, we
need to expose the brain on a daily basis to activities that are novel and
complex," explains Paul D. Nussbaum, Ph.D., neuropsychologist and chair of the
Prevention Advisory Board for the Alzheimer's Foundation of America. "It's human
nature to do what we're good at, but that's just rote processing. Passivity is
bad for the brain."
Dr. Nussbaum explains that mental challenges across one's lifespan delay the
onset of memory loss and related conditions later in life. "Many of the mental
disorders we associate with age really begin years and years before. The message
here is that we have to be proactive with our lifestyle early on."
Be a fathead
We spend a lot of time worrying about the fat building up around our belt
lines, but we should also be aware of the fat in our brains. "The brain is 60
percent fat, which makes it the fattiest part of the body," explains Nussbaum.
"Because we tend to eat the wrong kinds of fat in this country -- and not enough
omega-3 fatty acids -- the brain tends to be out of balance." Nussbaum advocates
for more "good" fat in the diet, particularly from fish sources, and for
consuming whole fruits and vegetables since they are rich in antioxidants.
Only recently has it been recognized that what we eat can actually alter our
genetic makeup. In the new area of nutritional neuroscience, researchers are
making connections between diet and a number of mental disorders, including
Alzheimer's disease, stroke and Parkinson's disease.
Do aerobic exercises
The link between physical exercise and mental health is seldom discussed but
easily understood: Every time your heart beats, 25 percent of the blood goes to
your brain. Whether you integrate plenty of walking into your daily routine or
set aside a few hours per week for running, swimming, calisthenics or even
dancing, staying active helps deliver critical payloads of glucose and oxygen to
the brain. Nussbaum notes that the brain's hippocampus, which is the hub of the
memory process, is particularly sensitive to oxygen deprivation and is the first
brain structure to malfunction when a person stops breathing. Recent studies
have shown that physical exercise can even promote the growth of new brain cells
in the hippocampus.
Plan time to relax
Stress hits the hippocampus, where memory is based. As noted by AARP,
negative, damaging and traumatic input can result in structural damage to this
sensitive brain area, and therefore to memory. But you can reduce stress through
daily meditation, deep breathing, massage, prayer or other modalities. There is
an adage among neuroscientists that "what is good for the body is good for the
brain." Similarly, the physical effects of stress are closely mirrored by
Join a book group
Sharing a book with a group of friends challenges your brain to absorb,
retain and recall new information -- a valuable route when it comes to exploring
the "novel and complex" concept outlined by Nussbaum. Critically, it's also an
avenue for socialization. Human interaction is a vital component of brain
development, which, contrary to earlier understanding, is a lifelong process.
Unfortunately, the elderly in our country are commonly isolated, and without
regular communication and intimacy the isolated brain tends toward dementia
(i.e., memory loss). But the social brain continues to be stimulated. Studies
have shown tremendous creativity and intellectuality among older people who are
well connected to friends and family.
