Who Gets Dementia?

  • There are about 750,000 people in the UK with dementia.
  • Dementia mainly affects older people. However, it can affect younger people: there are over 16,000 people in the UK under the age of 65 who have dementia.
  • Dementia can affect both men and women.
  • Scientists are investigating the genetic background to dementia. It does appear that in a few rare cases the diseases that cause dementia can be inherited. Some people with a particular genetic make-up have a higher risk than others of developing dementia.
