Study Details

Delayed Orthostatic Hypotension in Individuals with Parkinson's Disease

(IRB#: IRB_00170338)

A persons autonomic nervous system is the part of the nervous system that controls involuntary actions, such as the beating of your heart and the widening or narrowing of the blood vessels. Parkinson's disease can cause dysfunction of the autonomic nervous system causing orthostatic hypotension which is a form of low blood pressure that happens when you stand up from sitting or lying down. Orthostatic hypotension can make a person feel dizzy or lightheaded and may even cause fainting. Delayed orthostatic hypotension describes a drop of blood pressure happening beyond 3 minutes of standing. The purpose of this study is to learn the frequency and risk factors of delayed orthostatic hypotension in people with Parkinsons disease. The information will help clinicians be better aware of providing care to patients with delayed Orthostatic hypotension. People in the study will have their blood pressure and heart rate measured. There will be only one 20-minute study visit to measure these.
