What non-motor symptoms may show up later in those with Parkinson's disease?

ANSWER

Dementia and psychosis are two serious mental health issues that usually take a while to show up. Psychosis is a serious condition where you see or hear things that aren’t there, or believe in things that aren’t based in reality. Dementia means you can no longer think, remember, and reason well enough to carry on your normal life.

As you age, you’re more likely to have both conditions the longer you have Parkinson’s disease.
