Hallucinations

Some people with dementia may experiences hallucinations. Not everyone with dementia will be affected in this way, and not everyone who has these problems has dementia. It is important to remember that there are different types of hallucinations. Recent research shows that they are not as common in dementia as once thought.

'Visual mistakes' - such as illusions and misperceptions - are not hallucinations, though they are sometimes mistaken for them. See Factsheet 527, Visuoperceptual difficulties in dementia for more information.
