Memory loss and dementia


Dementia affects the normal working of the brain and can lead to a decline in a person's mental ability.

It can cause:

  • loss of memory
  • confusion
  • problems with speech
  • problems with understanding

Dementia is usually progressive and can eventually be severe. IT most commonly affects older people but it is not a normal part of ageing – most people experience healthy ageing without dementia.

Whilst rare before the age of 65, dementia can also affect younger people and may be easily missed as it is not usually associated with people this age.
