No matter
what your age, it's not too late to take steps to prevent memory loss. Good health habits can reduce the risk
of illnesses that might affect your memory as well as the likelihood that
you'll need medications that could have adverse side effects. And preliminary
studies have identified vitamins and at least one medication that may help ward
off dementia. Research shows that
the following strategies may help preserve your memory as well:
Physical
fitness and mental fitness go together. People who engage in regular vigorous
exercise also tend to stay mentally sharp into their 70s and 80s. A six-year
study of 1,740 adults ages 65 and older, reported in the Annals of Internal
Medicine in 2006,
found that people who exercised more than three times a week had a lower risk
of dementia than their sedentary counterparts.
Exercise
may help memory in several ways. First of all, it's good for the lungs, and
people who have good lung function are sending a higher volume of oxygen
through their blood vessels and into their brains. Second, exercise helps
reduce the risk for diabetes, high cholesterol, high blood pressure, and stroke
— diseases that can lead to memory loss. There is also some evidence that
exercise leads to increased connections between brain cells and enhances
neurotransmitter function. In one small study, 59 healthy individuals ages 60
to 79 took part in either aerobic training or stretching and toning sessions
for six months. The group that received regular aerobic training had
significant increases in brain volume in both gray and white matter. There were
no changes in brain volume in the stretching and toning group. Researchers
don't know precisely how much exercise is needed for good brain health.
Experts
recommend that you build physical activity into your daily routine. Here are
some examples:
· When
possible, walk instead of driving.
· Set aside
time each day for exercise — for example, a brisk half-hour walk around the
neighborhood. For motivation, ask your spouse or a friend to go with you.
· Use the
stairs instead of the elevator.
· Exercise at
home, possibly with an exercise video.
· Plant a
garden.
· Take an
exercise class or join a health club.
· Swim
regularly, if you have access to a pool or beach.
· Learn a
sport that requires modest physical exertion, such as tennis.
· If you
haven't been physically active recently, check with your doctor before starting
any exercise program.
In a recent
study, the characteristic that correlated most strongly with good mental
functioning in old age was a person's level of education. Experts think that
advanced education may help keep memory strong by getting people into the habit
of being mentally active. Regardless of your level of education, you, too, can
be an active, lifelong learner.
Exercising
your brain with challenging activities is believed to stimulate communication
between brain cells. Some ways of challenging your mind are obvious — for
example, doing crossword puzzles, reading, participating in a book discussion
group, playing chess, or taking classes. But you don't have to go to great
lengths to find mental stimulation. Mental challenges also come from the
unexpected occurrences that take you out of your daily routines and make you
think. If you're still working, chances are that you get some of these
curveballs thrown at you from time to time. But if you aren't working and your
time is largely unscheduled, you may need to actively seek novel experiences
and learning opportunities. Planning day trips or longer vacations, meeting
regularly with friends and acquaintances, going to the theater or to museums,
or just making a point of varying your routine can help keep your mind active
and engaged.
New
challenges and learning experiences help your mind thrive. It's a good idea to
try to develop new skills or relearn old ones that you may have set aside years
ago. Consider challenges such as these:
· Plan a
do-it-yourself project that requires some design work, such as building a deck,
creating a new tile pattern for your kitchen or bathroom, or designing a new
garden layout.
· At work,
initiate or volunteer for a project that involves a skill you don't normally
use.
· Get on the
Internet, if you aren't already. You will be challenging your mind by learning
computer skills and by gaining access to a wealth of information on almost any
conceivable topic. You may even find stimulating communication in the form of
chat groups or electronic mailing lists that focus on your interests. And
you'll be able to stay connected with friends and relatives via e-mail.
· Try cooking
new recipes. Experiment and change the recipes to improve them.
· Figure out
new driving routes to work or to other places that you go regularly.
· Join a club
to play chess, bridge, or poker.
· Rediscover
other challenging games that you can play alone or informally with friends.
Scrabble, Boggle, many card games, and even many computer games really make you
think.
· Write
essays — or even a book — about your life experiences. You may be able to
publish your work in your local paper, on a Web site, or elsewhere.
· Take a
class in a new or old skill such as playing a musical instrument, music
appreciation, or painting.
· Do puzzles
and brainteasers. In addition to the crossword puzzle in your newspaper, you
can find math brainteasers and word problems in books and magazines and on the
Internet. Try doing some instead of watching TV when you have a free evening.
Jigsaw puzzles challenge the mind, too.
Smokers
perform worse than nonsmokers in studies of memory and cognitive function.
Smoking increases the risk for stroke and hypertension, two other causes of
memory impairment. No one knows whether smoking directly impairs memory or is
merely associated with memory loss because it causes illnesses that contribute
to poorer brain function.
Regardless
of the exact nature of the link between smoking and memory loss, if you smoke,
it pays to quit. Research shows that people who stop smoking have less
cognitive decline than people who continue to smoke.
While heavy
drinking can harm your memory, moderate consumption of alcoholic beverages may
actually be beneficial (see "Alcohol use"). Research suggests that
moderate drinking reduces the risk of dementia. But excessive consumption of
alcohol is toxic to neurons and is the leading risk factor for Korsakoff's
syndrome, a disorder that causes sudden and irreversible memory loss. If you
have been a heavy drinker, cutting back can prevent further memory loss and
will usually lead to some recovery of damaged memory function.
A
nutritious diet rich in fruits and vegetables as well as healthy fats from
fish, nuts, and whole grains is vital to maintaining brain health. Avoiding
saturated fats (in meat and dairy) and trans fats (in commercial products with
partially hydrogenated oils) will help keep your arteries clear and cholesterol
levels healthy, and that in turn will decrease your chances of heart disease
and stroke, including the small "silent" strokes that can damage
brain function. Avoid excess calories to maintain a normal weight; this lowers
your risk for illnesses such as diabetes and hypertension, which can impair
your memory.
Eating a
lot of fruits and vegetables can be especially beneficial because many are good
sources of vitamins and other nutrients that may protect against diseases and
age-related deterioration throughout the body.
If you eat
a healthy diet, chances are that you are already getting most if not all of the
vitamins that you need. However, aging can make you vulnerable to vitamin
deficiencies due to nutritional restrictions and malabsorption syndromes.
Taking a high-quality multivitamin is a good start toward ensuring that you are
getting what you need. Individual vitamin supplements can also play a role.
Certain B
vitamins (B6, B12,
and folic acid) are important for neuronal protection as well as facilitating
the breakdown of homocysteine, an amino acid in the blood that, at high levels,
is a risk factor for heart disease, stroke, and peripheral vascular disease
(see "B vitamins"). Deficiencies of B vitamins tend to become more
prevalent with age. Work with your doctor to monitor your homocysteine level,
and correct B-vitamin deficiencies with supplementation when necessary.
And despite
the uncertainties, it's reasonable to speculate that a diet rich in vitamin E
may help delay or prevent the development of Alzheimer's disease. So include
foods such as wheat germ, vegetable oils, whole grains, and leafy green
vegetables in your diet. The benefits of vitamin E supplements are less clear.
The Alzheimer's Association recommends that people already diagnosed with
Alzheimer's take vitamin E only under the care of a physician. One reason for
their concern is that high-dose vitamin E can interfere with the blood's
clotting ability, raising the risk of hemorrhagic (bleeding) stroke. If you
take blood-thinning medication such as warfarin (Coumadin) or aspirin, you
should be especially cautious and talk with your doctor before taking vitamin
E.
Sleep is
essential for memory consolidation as well as overall health. Although people
vary widely in their individual sleep needs, research suggests that six to
eight hours of sleep a night is ideal. Perhaps even more important than the
amount of sleep is the quality of sleep. People with breathing problems during
sleep, such as obstructive sleep apnea, can sleep for 10 hours per night but
still feel tired in the morning. Of course, for some people, getting a good
night's sleep is easier said than done, particularly because insomnia becomes
more common with age. But certain habits can help. For example, try the
following:
· Establish
and maintain a consistent sleep schedule and routine. Go to bed at the same
time each night and wake up at the same time each morning. A set sleep routine
will "train" you to fall asleep and wake up more easily.
· Plan to do
your most vigorous exercise early in the day. Exercising in the hours immediately
before bedtime causes physiological changes that may interfere with sleep.
Exercising in the morning, on the other hand, enhances your alertness when you
need it most — at the beginning of the day.
· Avoid
coffee and other sources of caffeine (e.g., chocolate, many soft drinks, some
brands of pain relievers, many types of tea) after midmorning, because caffeine
is a stimulant that can keep you awake for hours afterward.
· Avoid
excessive napping during the daytime. Prolonged napping can disrupt your natural
sleep cycle and prevent you from feeling tired enough to fall asleep at night.
· Don't take
sleeping pills unless nothing else works. If you do take a prescription sleep
medicine, work with your doctor on using it effectively but only on a
short-term basis, because sleeping medications can be habit-forming. In
addition, like sleep deprivation, sleeping pills can cause memory loss.
· Some people
find that drinking warm milk before bedtime helps them feel sleepy. Milk
contains tryptophan, a chemical that may help you relax.
· Don't try
to sleep if you're not tired; otherwise you'll set yourself up for tossing and
turning. If you're still awake after about 20 minutes in bed, get up and read
awhile to help you relax.
· If you
experience persistent sleep problems, consult your physician so that you can
identify the specific issues and get the necessary treatment.
Social
support — that is, close ties with others — can improve the cognitive
performance of older people, according to the MacArthur study on aging and
other research. Social support can come from relationships with friends,
relatives, or caregivers.
A 2008
study of 3,610 people between the ages of 24 and 96 looked at the relationship
between participants' mental function and their level of social contact based
on how often they talked on the phone to friends, neighbors, and relatives. The
researchers found that the higher the individual's level of social interaction,
the better their mental function; this result was found across all age groups.
A second study by the same team compared the cognitive effects of 10 minutes of
group discussion against a similar amount of time spent in solitary
intellectual activities such as silent reading or crossword puzzles. When
tested on mental processing speed and working memory, the group that engaged in
social interaction performed better.
There are
several ways that social engagement may benefit your memory. Intellectually
stimulating activities often go hand in hand with social interaction. Social
relationships can also provide support during stressful times, reducing the
damaging effects that stress can have on the brain.
When you're
under a lot of stress, it's hard to concentrate. And not concentrating
sufficiently is one of the main causes of poor learning and memory. Being under
sustained stress for many weeks can impair your memory by altering brain
chemistry and damaging the hippocampus. You can't control all the stressful
events in your life, but you can control your reactions to those events to some
degree.
One way to
reduce stress is to work on gaining a greater sense of control over your life.
The MacArthur Foundation's study on aging found that the people who reported
the most "self-efficacy," or mastery, also had the best memory in old
age. The researchers viewed self-efficacy as a buffer against the feeling of
helplessness that often contributes to stress.
There's no
one-size-fits-all strategy for reducing stress. You have to find strategies
that work for you. For some people, taking a brisk walk or getting other kinds
of regular exercise helps. Listening to music, meditating, talking to a friend,
or engaging in a relaxing activity, such as gardening or knitting, can also
help you cope with stressful situations. If you can't lower your stress level
on your own, you might benefit from counseling.
Head trauma
is a major cause of memory impairment and a risk factor for future development
of dementia. You can prevent head trauma by using the appropriate gear during
high-speed activities and contact sports.
Wear seat
belts when riding in motor vehicles. Car accidents are by far the most common
cause of brain injury, and wearing seat belts greatly reduces the injury risk.
Wear a helmet when bicycling, riding on a motorcycle, in-line skating, and
skiing. Wear a mouth guard to lower the risk of a concussion by deflecting the
force of a blow to the chin during contact sports such as football, ice hockey,
soccer, basketball, rugby, and martial arts.
Reduce your
exposure to toxic substances by taking sensible precautions. Before using
paints, solvents, and pesticides, read the labels for safe handling. Test your
home water supply and use a water filter to eliminate lead, if necessary. Avoid
sanding, scraping, and otherwise disrupting lead paint on older homes. If you
do plan to remove lead paint, hire a government-approved contractor for this
work. Have your car and furnace serviced regularly to minimize carbon monoxide
emissions.
