Hallucinations and delusions

Hallucinations are a key feature of dementia with Lewy bodies. This video explains how hallucinations and delusions can affect people with DLB.

Watch Professor Rob Howard describe:

  • how common hallucinations and delusions are in DLB
  • the negative effect they can have on patients
  • why visual hallucinations are particularly common in DLB
  • the different types of delusions that can occur

Hallucinations are perceptions of things that aren’t really there, so a visual hallucination may be experienced in exactly the same way as perception, except there isn’t a visual stimulus causing it. In this link for the Alzheimer’s Society, you can read a bit more about the hallucinations that are common in DLB.

Delusions are beliefs that aren’t true, and are believed even if evidence is given that contradicts the belief.

The Alzheimer Society of Canada has some more information on delusions and hallucinations in dementia.
