Hallucinations and delusions

Some people with Parkinson's may experience hallucinations or delusions. They are more common in advanced Parkinson's.

A hallucination is when you see, hear or feel things that aren't there.

Delusions are unusual thoughts, beliefs or worries that aren't based on reality.

If you start to experience hallucinations or delusions, or if you have had them before, and the symptoms seem to be getting worse, it is important to get advice from your GP, specialist or Parkinson's nurse as soon as possible.

Hallucinations and delusions usually happen in the later stages of Parkinson's. They can affect both younger and older people in the earlier stages of the condition, but this is less common.

Usually, when people with Parkinson's experience hallucinations and delusions, it will be a side effect of their medication rather than a direct symptom of Parkinson's.
