Summary

This study looks at how blood pressure changes when standing affect thinking and brain blood flow in people with Parkinson's disease. About 60 participants, with and without orthostatic hypotension (low blood pressure on standing), will take thinking tests while lying down and standing up. The goal is to find out what level of low blood pressure starts to affect thinking, which could lead to better treatment and prevention of cognitive problems.
