This is an observational study, meaning it collects information over time rather than testing a specific treatment. Researchers are gathering detailed information from people with Parkinson's disease, Parkinson's disease dementia, Lewy body Parkinson's disease, and Lewy body dementia with behavioral disturbance. This includes your medical history, symptoms, and how you respond to treatments. The goal is to understand the long-term effects of these conditions and identify genetic and biological factors that influence them, which could lead to better ways to diagnose and manage symptoms. You may be eligible to participate if you receive care for Parkinson's disease with mild cognitive impairment (MCI) or dementia, and can complete the study assessments.
