What is dementia?

Dementia is a word used for a group of symptoms caused by different diseases that affect the brain. ‘Symptom’ means a sign or indication.

Your risk of developing dementia increases as you get older but not all older people develop dementia. Dementia is not a natural part of getting older because it is caused by diseases that damage the brain.
