Delusions and hallucinations are two symptoms of Parkinson’s disease psychosis (PDP). This is when some people with Parkinson’s have trouble distinguishing reality from things that are imagined. PDP consists of nonmotor symptoms of psychosis that affect the mind rather than the body.
In hallucinations, people perceive things that are not there. They can involve all five senses: visual, auditory, smell, taste, and touch.
On the other hand, delusions are irrational beliefs in which someone strongly believes something that is not true or evidence-based. Researchers have found that persecutory delusional beliefs are the most common type of delusion in people with Parkinson’s. They occur when someone falsely believes that others are treating them badly or taking advantage of them.
