Many people expect to live to age 90 and beyond. The chances of developing Alzheimers (the most common type of dementia) or other types of dementia increase as we get older. Many of my patients ask me, How do you keep your brain healthy? It would be nice if there were a simple supplement or medication to prevent dementia, but unfortunately, this is not the case. The good news is there are things you can do to improve your overall health and well-being as you get older, and these things also help keep your brain healthy.First, its important to take care of your physical health. Avoid tobacco or too much alcohol. For people over 65, that means no more than one drink per day. Some medications, including over the counter, can harm the brain, so review your medications with your doctor or pharmacist at least once a year. If you have high blood pressure, diabetes, or high cholesterol, work with your health care team to keep these conditions under control. Enjoying a healthy diet with plenty of fresh fruits and vegetables is also helpful."Second, get plenty of physical activity this is one of the best things you can do for your brain health. With more physical activity, youll feel better, sleep better, have less stress, and have more energy. Choose an activity that you enjoy and invite a friend or family member to join you. If you are just starting out, go slow and gradually increase, with a goal to get to at least 30 minutes of moderate activity (like a brisk walk), at least five days a week.Third, learning new things helps form new connections in your brain. Dusting off an old musical instrument, learning a new language, or solving puzzles are examples of fun activities to try.Finally, its essential to stay socially connected. Spend time nurturing friendships and family relationships. The same things that make life enjoyable are also the things that help to keep your brain healthy.
