Hallucinations and Delusions in Parkinson’s Disease

It might be surprising to learn that 20 to 30 percent of people with Parkinson’s disease (PD) will experience visual hallucinations. While typically not a symptom of PD itself, they can develop as a result to a change in PD medication or as a symptom of an unrelated infection or illness. It is important to know the signs of hallucinations and how to manage them.
