Controlling Dementia Risk Factors

There is currently no cure nor effective drugs for treating Alzheimer’s disease and vascular dementia. The number of individuals with dementia will grow in the coming years. This will stress both our health care system and already overburdened caregivers. Prevention is currently the best approach to these disorders.


Multiple clinical trials have established important risk factors for stroke and vascular demention. These include:

  • Hypertension (high blood pressure)

  • Myocardial infarction (heart attack)

  • Atrial fibrillation

  • Diabetes mellitus

  • Carotid artery disease

  • Smoking

  • Alcohol use

  • Low physical activity

  • Diet


Although there are few clinical trials on preventing Alzheimer’s dementia, modifiable risk factors have been identified in observational studies. Controlling these risk factors in mid-life may reduce the chance of developing Alzheimer’s Disease later. These risk factors include:

  • Hypertension (high blood pressure)

  • Type 2 diabetes mellitus

  • Lack of physical activity

  • Low social activity

  • Depression

  • Hearing loss

  • Low education level

  • Smoking

  • Obesity
