Column: How to stave off cognitive decline as you age
Simple, evidence-based habits can sharpen memory and lower dementia risk.
Published
Dear Savvy Senior,
Are there any proven
strategies to preventing cognitive decline? I have a family history of dementia
and worry about my own memory and cognitive abilities as I grow older.

Dear Forgetful,
For most people, starting in their 50s and 60s, the
brain’s ability to remember names, multi-task or learn something new starts
declining. While our genes (which we can’t control) play a key role in
determining our cognitive aging, our general health (which we do have some
control over) plays a big factor too.
Here are some healthy lifestyle strategies — recommended by
medical experts — you can employ that can help stave off cognitive loss and
maybe even build a stronger brain:
—Manage health problems:
Studies have shown cognitive problems are related to health conditions, like
diabetes, heart disease and even depression. So if you have high blood
pressure, high cholesterol or diabetes, you need to treat them with lifestyle
changes and medication if necessary and get them under control. And if you
have a history of depression, talk to your doctor about treatment options.
—Exercise: Aerobic
exercise increases blood flow to all parts of your body including your brain to keep the brain cells well-nourished. So choose an aerobic activity you
enjoy like walking, cycling, dancing, swimming, et cetera, that elevates your heart
rate and do it for at least 30-40 minutes three times a week.
—Eat healthy: A
heart-healthy diet, like the Mediterranean diet, also will help protect the
brain. A Mediterranean diet includes relatively little red meat and emphasizes
whole grains, fruits and vegetables, fish and shellfish, nuts, olive oil, and other healthy fats. Also keep processed foods and sweets to a minimum.
—Get plenty of sleep: Quality,
restful sleep contributes to brain health too. Typically, adults should get between seven and nine hours of sleep
daily. If you have persistent problems sleeping, you need to identify and
address the problem. Medications, late-night exercise and alcohol can interfere
with sleep quality and length, as can arthritis pain, sleep apnea and restless
leg syndrome. If you need help, make an appointment with a sleep
specialist, who will probably recommend an overnight diagnostic sleep test.
—Challenge your mind: Some
research suggests mind-challenging activities can help improve memory and
slow age-related mental decline. But be aware these activities consist of
things you aren’t accustomed to doing. In other words crossword puzzles aren’t
enough to challenge your brain if you’re already a regular puzzle-doer.
Instead, you need to pick up a new skill like learning to dance, play a musical
instrument, study a new language or do math problems, something that’s
challenging and a little outside your comfort zone.
Brain-training websites like Lumosity, Elevate and Peak are good
mind exercising tools because they continually adapt to your skill level to
keep you challenged.
Socializing and interacting with other people is another
important way to stimulate the brain. So make a point to reach out and stay
connected to friends, family and neighbors. Join a club, take a class or even
volunteer — anything that enhances your social life.
—Don’t smoke or drink:
Smoking and regular alcohol consumption both affect the brain in a negative
way, so kick the habit if you smoke. If you drink, do so only occasionally.
—Check your eyes and ears: A growing body of evidence
shows vision and hearing loss, which affect brain stimulation, also can increase the risk of cognitive decline. So get your eyes and ears checked
regularly and treat any issues promptly.
—Reduce stress: Some
stress is good for the brain, but too much can be toxic. There’s evidence that
things like mindfulness meditation, yoga and tai chi are all good ways to help
reduce stress.
