Parkinson’s disease is a disorder of the central nervous system. The signs and symptoms of it can vary from person to person, but generally fall into two types: motor symptoms and non-motor symptoms.
Hallucinations and delusions are non-motor symptoms of Parkinson’s disease. Over the course of their disease, over 50% of people with Parkinson’s will experience these symptoms, which are often defined as:
Seeing, hearing, or experiencing things that aren’t real
Believing things that aren’t true
