Simple Ways to Prevent Alzheimer's
You may think that Alzheimer's is a by-product of aging, but author Jean Carper
(pictured) wants you to know that you can avoid the disease. After the former
CNN medical correspondent and bestselling author discovered she was genetically
at risk for Alzheimer's, Carper interviewed experts and reviewed medical
research to better understand the disease and how to prevent it. She turned her
research into a book full of easy-to-follow advice. Read an excerpt from her
book, "100 Simple Things You Can do to Prevent Alzheimer's."
Ask Questions About Anesthesia
It's not uncommon to be in a mental fog when you come out of surgery but on
occasion, doctors see cases like the sixty-five-year-old woman who, six months
after hipsurgery, develops memory loss and is later diagnosed with Alzheimer's.
This has caused concern that anesthetics may accelerate the onset of dementia
and Alzheimer's, especially in vulnerable elderly brains. Rudolph Tanzi, PhD, a
renowned Alzheimer's genetics researcher at the Massachusetts General Hospital
in Boston, has focused on the hazards of isoflurane, a widely used general
anesthetic. As quoted in Forbes magazine, Tanzi explained, "We don't have
enough data yet to ban isoflurane, but I'm convinced enough that I won't let my
mother have it. I would advise any family or friends to stay away from
isoflurane. There is a lot of speculation here, and a lot of work needs to be
done, but at this point I wouldn't take a chance." Reported postsurgical
cognitive problems and irreversible memory
loss seem to affect mainly older people who are particularly susceptible to
Alzheimer's. Talk over any concerns with your anesthesiologist and be aware of
the potential problem and alert for the results of further research.
Don't Shy Away From Antibiotics
Stories of people with Alzheimer's becoming lucid after taking antibiotics are
so legendary that doctors cannot disregard them. In one case, an elderly woman
with Alzheimer's was near death and taken to an emergency room, where she was
given an antibiotic drip for lung congestion. She had a mental revival that
astounded her daughter: "She recognized us, was able to put three words
together, and understood and responded to everything we said to her. She has
not been this responsive in close to a year! I attribute it to the antibiotic
drip." Brian J. Balin, PhD, a professor at the Center for Chronic Disorders of
Aging, Philadelphia College of Osteopathic Medicine, says that he often hears
such stories of cognitive recovery after patients have taken antibiotics, and
he's not really surprised. Balin is a leading authority behind the unorthodox
theory that infections are a cause of Alzheimer's. However, antibiotics are not
a permanent solution. As soon
as they are stopped, the mental improvement disappears, says Balin. Do not
take antibiotics specifically to ward off Alzheimer's, but be aware that
antibiotics may be brain protective and not to shy away from taking them when
they are warranted to fight a specific infection. Avoid excessiveexposure to
antibiotics that are not clearly needed to combat a particular illness.
Control Bad Cholesterol
You're in your forties. You find out your blood cholesterolis high. You
probably know it could mean heart diseaseahead. You may not know it also
predicts Alzheimer's, according to the largest study ever done on the subject.
Researchers at Kaiser Permanente's Division of Research and the University of
Kuopio in Finland collected data for over four decades on nearly ten thousand
men and women. Their conclusion: high total cholesterol is an early warning
sign that appears three or four decades before dementiadoes. Thus, it's
important to get cholesterol down in midlife rather than waiting until old age,
when it may be too late to stop or reverse its harm to the brain. Pay attention
to harmful cholesterol early in life. Get the bad type down and the good type
up. That means a heart-healthy Mediterranean-type diet -- low in saturated
fatand trans fats, with lots of fish, fruits, vegetables, and whole grains --
aerobic exercise, normal weight, and, if
required, cholesterol-lowering drugs.
Have Your Eyes Checked
If you preserve good or excellent vision as you age, your chances of developing
dementia drop by an astonishing 63 percent. And if your vision is poor, just
seeing an ophthalmologist for an exam and possible treatment at least once in
later life cuts your dementia odds by about the same amount -- 64 percent,
according to a recent study at the University of Michigan Health System. Be
aware that your eyes reflect and influence how your brain is functioning,
especially as you age. Don't tolerate poor vision. It can often be corrected,
dramatically cutting your risk of dementia. See an ophthalmologist for at least
one examination in late life, and have yearly screenings if possible.
Surf the Internet
It's a scientific fact: doing an Internet search can stimulate aging brains
even more than reading a book. So finds Gary Small, MD, director of the UCLA
Center on Aging. "Internet searching," he says, "engages complicated brain
activity, which may help exercise and improve brain function." Using MRI scans,
Small found that activation picks up dramatically in the brains of experienced
Web surfers -- mainly in regions related to decision making and complex
reasoning, which are not stimulated simply by reading. Another way to stimulate
your brain online is to play quick "brain games, "so look into
brain-fitness-training software but check to see if there it relies on solid
science before you buy.
Drink Juices Of All Kinds
It's easy to get up in the morning and have a glass of juice. It's also
startling how much that simple act can slash your chances of Alzheimer's.
Compelling research from the Vanderbilt University School of Medicine in
Nashville shows that the risk of Alzheimer's plummeted 76 percent in people who
drank fruit or vegetable juice more than three times a week, compared to those
who drank juice less than once a week. Fascinating research by James Joseph,
PhD, at Tufts University and Robert Krikorian, PhD, at the University of
Cincinnati showed that drinking Concord grape juice or commercial blueberry
juice improved short-term and verbal memory in older people with early memory
loss and a high risk of Alzheimer's. Make it a habit to drink a glass of juice
every day. It may be smart to drink more of the deep-colored, brain-proven
juices, such as grape, pomegranate, and blueberry juice, but don't forget
orange and grapefruit, pineapple, mango, cherry, prune,
and all the rest. They, too, are apt to have brain benefits. Be sure to drink
only 100 percent fruit or vegetable juices, not "fruit drinks." Look for "no
sugar added" on the label.
Don't Be Lonely
Loneliness has emerged as a prime predictor of Alzheimer's. In a Rush
University study on loneliness and the risk of Alzheimer's people with the
highest loneliness scores were twice as apt to develop Alzheimer's as those
with the lowest. Who's most vulnerable? Not surprisingly, older people who live
alone and have experienced the death of a spouse or an intimate friend. It's
not easy to fix, since loneliness strikes at various ages and may be more of a
personality trait than the result of circumstances. Therapy and possibly
antidepressants (loneliness is tied todepression) to help stop cognitive
damage, preferably before it becomes severe. Also, you should avoid social
isolation; it worsens loneliness. If you know older people who are lonely,
reach out to them.
Embrace Marriage
According to a large study from Sweden and Finland, being married or living
with a significant other keeps Alzheimer's away. Living alone makes you much
more vulnerable, especially if you're a woman. Having a partner in midlife
(around age fifty) cut the risk of being cognitively impaired after age
sixty-five in half. In contrast, middle-aged singles (the divorced, widows,
widowers, and never-marrieds) were two to three times more apt to have dementia
in late life than members of a couple. Researchers theorize that intense social
interactions build "brain reserve," which increases resistance to memory loss
and Alzheimer's but for the moment, why singles are so at risk is still largely
a mystery. If you have a spouse or significant other, consider yourself lucky.
If you don't, compensate by forming strong social ties among a large circle of
friends and relatives. All socializing appears to keep brains happier and
healthier and Alzheimer's at a more
comfortable distance.
Take Care of Your Teeth
People with tooth and gum disease are apt to score lower on memory and
cognition tests, according to a University of West Virginia School of Dentistry
analysis. Researcher Richard Crout, DDS, theorizes that an infection
responsible for gum disease gives off inflammatory by-products that travel to
areas of the brain involved in memory loss. These inflammatory agents may be
toxic to brain cells. Consequently, Crout says brushing, flossing, and
generally preventing gum disease may help keep your gums and teeth healthy, and
also your memory sharper. Be sure you and everyone in your family get treatment
early in life to control bleeding, inflamed gums. It could help save your brain
from inflammatory assaults leading to memory loss and dementia later in life,
experts say.
Put Vinegar in Everything
Vinegar does not confront Alzheimer's directly but there is evidence that
vinegar sinks risk factors that may lead to memory decline and dementia --
namely, high blood sugar, insulin resistance, diabetes and prediabetes, and
weight gain. Studies at Arizona State University have found that vinegar can
curb appetite and food intake, helping prevent weight gain and obesity. Swedish
investigators agree. In one study, downing two or three tablespoons of vinegar
with white bread cut expected rises in insulin and blood sugar by about 25
percent. Pour on the vinegar -- add it to salad dressings, eat it by the
spoonful, even mix it into a glass of drinking water. Any type of vinegar works
because it's the acidity that counts.
