Hi There I understand your concern and would like to tell you that Alzheimer s disease can t be be prevented but with the help of healthy lifestyle can reduce the risk of Alzheimer s disease. Factors like physical activity, healthy eating and keeping your brain active through lifelong learnings reduces the risk of dementia. Specific Alzheimer prevention strategies include -Avoid smoking -Control vascular risk factors, including high blood pressure, high cholesterol and diabetes -Eat a balanced diet—such as the Mediterranean diet—that s rich in vegetables, fruits and lean protein, particularly protein sources containing omega-3 fatty acids -Be physically and socially active, including engaging in aerobic exercise -Take care of your mental health -Use thinking (cognitive) skills, such as memory skills Hope to have been helpful Kind Regards Dr. Navneet Bansal
