Parkinson's Disease Symptoms: Dementia

Some Parkinson's disease patients experience dementia, or impairment of mental functioning.

About 0.2 percent to 0.5 percent of those with Parkinson's over age 65 will have problems with dementia (PDD), including trouble with their memory, attention spans, and what is called executive function - the process of making decisions, organizing, managing time, and setting priorities.
