Parkinson’s disease, which affects an estimated 1 million Americans, is a progressive nervous system disorder that damages the brain and nerve cells that control movement. This damage can lead to tremors, muscle rigidity, stiffness in the legs and body, and difficulties walking and keeping balanced. Parkinson’s disease commonly affects people starting in their 50s.

Symptoms of nOH, including dizziness, lightheadedness, muscle weakness, and feeling faint after standing, can occur in a person who is at any stage of Parkinson’s disease. People often think these symptoms are part of their Parkinson’s disease and are something they must learn to live with, but these symptoms may be a sign of nOH—a separate condition that can also be managed.
