A: There’s no proven prevention for any of these diseases. The biggest risk factor is aging, and you can’t prevent that. You can’t alter family history and genetics, either.
Lifestyle choices, such as eating well and exercising, are associated with a lower risk of developing dementia. I subscribe to the “use it or lose it” approach to keeping your brain healthy. Your brain is like a muscle—use it or lose it.
1. Stay mentally active. Research suggests that brainy activities stimulate new connections between nerve cells and may even help the brain generate new cells. You can do many things to keep your brain in shape, such as doing crossword puzzles or Sudoku, reading, playing cards or putting together a jigsaw puzzle.
2. Exercise regularly. Regular physical activity benefits the brain. Research shows that people who remain physically active are less likely to experience a decline in their mental function and have a lower risk of developing Alzheimer’s disease. Try to exercise several times per week for 30–60
minutes. Walk, swim, play tennis or do any other moderate aerobic activity that increases your heart rate and increases blood flow to the brain.
3. Get plenty of sleep. Sleep plays an important role in your brain health. There are some theories that sleep may help clear abnormal proteins in your brain and consolidates memories, which boosts your overall memory and brain health. Try for seven-to-eight consecutive hours of sleep each night. Research indicates sleep obstructive sleep apnea and stress can impair memory. Sleep apnea harms your brain’s health and maybe a reason why you may struggle for long stretches of uninterrupted sleep. Talk with your doctor if you or a family member suspects you have sleep apnea.
4. Improve your diet. Consider following a Mediterranean diet, which emphasizes plant-based foods, whole grains, fish and healthy fats, such as olive oil. It incorporates much less red meat and salt than a typical American diet. There’s research to suggest that people who follow a diet like the Mediterranean diet are less likely to develop cognitive impairment and dementia.
5. Stay social. Social interaction helps keep away depression and stress, which can contribute to memory loss. Connect with loved ones, friends and others, especially if you live alone. There is research that links solitary confinement to brain atrophy, so remaining socially active may have the opposite effect and strengthen the health of your brain.
