What causes Alzheimer's?

The exact cause of Alzheimer's disease is not fully understood, but it is believed to be a combination of genetic, environmental, and lifestyle factors.

  • Genetics: Some people have a genetic predisposition to Alzheimer's, meaning they are more likely to develop the disease because of certain genetic mutations they inherited from their parents. The most common genetic risk factor is the presence of a specific allele of the Apolipoprotein E gene (APOE-e4)
  • Age: The risk of developing Alzheimer's increases with age, most people with Alzheimer's are 65 or older.
  • Lifestyle: Research has shown that several lifestyle factors may influence the risk of developing Alzheimer's, including poor diet, lack of physical activity, smoking, and high alcohol consumption.
  • Environment: Exposure to certain toxins or viruses, head injuries, and other factors, may also play a role in the development of Alzheimer's.
