Can Alzheimer’s disease be prevented? Researchers across the world are racing towards a cure for Alzheimer’s disease. But as prevalence rates climb, the focus has broadened from treatment to prevention strategies. What they’ve discovered is that it may be possible to prevent or delay the symptoms of Alzheimer’s disease and other dementias through a combination of healthy habits. Most causes of dementia are not preventable. However, many drug companies, foundations, and non-profit organizations are all actively researching ways to slow, delay, and prevent dementia. Many are particularly focused on Alzheimer’s disease.

Vascular dementia is caused by a series of small strokes. There are steps you can take to reduce your risk of stroke. If you smoke, quit. If you have high blood pressure and/or diabetes, talk with your doctor about getting those under control. Many studies strongly suggest that a low-fat diet and regular exercise may also reduce the risk of vascular dementia.

Some conditions mimic dementia or have dementia-like systems. Those include changes in blood sugar, sodium and calcium, as well as low vitamin B-12 levels. If caught early, these may be treatable. If you have symptoms, don’t delay seeing your doctor.

Diet
Evidence suggests that eating a Mediterranean diet may decrease your risk of developing AD. A Mediterranean diet consists of little red meat and large amounts of the following:

  • Whole grains
  • Fruits and vegetables
  • Fish and shellfish
  • Nuts, olive oil, and other healthy fats

Social Engagement
Research suggests that seniors who spend most of their time in their home environment are almost twice as likely to develop Alzheimer’s disease as those who travel out of town. It is unclear whether better health results in more travel or more travel results in better health.

Raise Your C Level
Vitamin C is an antioxidant, essential for healthy skin and blood vessel functioning, but some studies suggest it may also protect against dementia-related brain plaque. Oranges, limes and lemons are a convenient source of ascorbic acid (aka vitamin C), as are sweet peppers, strawberries, cantaloupe, tomatoes, broccoli and leafy greens.

Get Full of Beans
Beans and green peas provide a rich source of B-complex vitamins, which may play a role in protecting against brain shrinkage, as well as in maintaining blood sugar levels and a healthy nervous system. Vitamin B-1 (thiamine and folic acid) is also found in enriched grain products and cereals.

Get Some Sun
New research suggests that adults with low levels of vitamin D may have a higher risk of developing dementia, Alzheimer’s or other cognitive problems. Exposing your sunscreen-free face, back, arms or legs to no more than 10-15 minutes of sunshine a few times a week could boost D levels.

Get Plenty of Omega-3 Fats
Evidence suggests that the DHA found in omega-3 fatty acids may help prevent Alzheimer’s disease and dementia by reducing beta-amyloid plaques. Food sources include cold-water fish such as salmon, tuna, trout, mackerel, and sardines. You can also supplement with fish oil.

Learn Something New
Study a foreign language, learn sign language, practice a musical instrument, read the newspaper or a good book, or take up a new hobby. The greater the novelty and challenge, the larger the deposit in your brain reserves.

Establish a Regular Sleep Schedule
Going to bed and getting up at the same time reinforces your natural circadian rhythms, your brain’s clock response to regularity.

There’s less of a separation between brain and body than you might think. As mentioned above, what’s good for the body — like sleep, exercise, and nutritious food — is also good for the brain. And that also means that the converse is true: things that are bad for the body are also damaging to the brain. You owe it to yourself to work with your body to keep your brain healthy.
