What biological factors cause Alzheimer’s?

  • Down syndrome.
  • Head injury.
  • Other factors.

What are the biological factors of dementia?

Biological risk factors

  • Ageing. Age is the most important known risk factor for AD.
  • Family history of dementia. Some genetic risk factors have been identified so far, but only a small proportion of AD cases can be explained by specific gene mutations.
