Forgetfulness as you grow older does not mean you have dementia. Moreover, there are many kinds of dementias, including Alzheimer’s. If you are experiencing severe memory problems, you need a medical diagnosis. Some dementias are reversible.

Until further research is done on ways to correct memory lapses, forget the claims of supplement makers. So far, there’s no brain supplement that will help you recall a name or find your keys.

To keep your mind functioning at a high level, mental workouts are best. Use the powers you have. Cultivate your interests, learn something new, take a course, read more. Play games that exercise your memory, your powers of concentration, and your analytic ability. Physical workouts also help maintain your brain, as does a healthy diet.
