Clinical trials: Pure Autonomic Failure
Parkinson's Disease, Multiple System Atrophy
Clinical Laboratory Evaluation of Chronic Autonomic Failure
Background: The autonomic nervous system controls automatic body functions. Researchers want to improve the tests used to diagnose autonomic failure. Orthostatic hypertension is a drop in blood pressure when a person stands up.
