Alzheimer's Disease - What Increases Your Risk

Certain things make getting a disease more likely. These are called risk factors. Risk factors for Alzheimer's disease include:

  • Getting older. This is the main risk factor. People rarely have dementia before age 60.
  • A family history of Alzheimer's disease, especially if one or more of your parents or siblings has the disease.
  • The presence of the apolipoprotein E-4 gene.
  • Having Down syndrome.
  • Injuries to the brain, especially more than one injury that caused you to pass out (such as a concussion from a fall, car accident, or playing a sport.)
