Alzheimer’s Disease

Lifestyle modifications


  • A healthy lifestyle that includes no smoking, avoid high alcohol intake, physical activity, healthy eating, normal weight (1)

  • Maintain social activities/interaction and cognitive/educational activities (2)

  • Intensive risk factor modification may reduce the risk of dementia or prolong time to onset if done no later than 45-65 years of age (2)

  • Exercise alone does not seem to reduce the risk of dementia (2)

  • Cognitive training has uncertain long term effects on cognitive decline (2)

  • Berries high in flavonoids may reduce the risk of dementia (2)

  • Vitamin E supplementation may be effective in slowing progression of mild to moderate Alzheimer (2)

  • Healthy lifestyle: A healthy lifestyle based on smoking status, physical activity level, diet and alcohol consumption is associated with reduced risk of dementia among people with high genetic risk. An unhealthy lifestyle is associated with increased risk of dementia (3)

  • Individualized multidomain intervention: Patients at risk for AD dementia may experience improved cognitive  function and reduced AD risk scores through personalized  multidomain interventions (4).
