Risk factors for Alzheimer’s disease

Researchers have identified several risk factors for Alzheimer’s disease.

These include:

  • Age: According to the Alzheimer’s Association, the single greatest risk factor for Alzheimer’s disease is age. People over 65 years are more likely to develop Alzheimer’s. By the time they are 85 years, 1 in 3 people are estimated to have the condition.
  • Family history: Having a close relative with Alzheimer’s disease increases a person’s chance of developing it.
  • Head trauma: A person who has had serious head trauma in the past, such as from a motor vehicle accident or from contact sports, appears to be at greater risk of developing Alzheimer’s disease.
  • Heart health: Heart or vascular conditions may increase the chance of developing Alzheimer’s disease. Examples include high blood pressure, stroke, diabetes, heart disease, and high cholesterol.
