About Multiple System Atrophy (MSA) and Symptomatic Neurogenic Orthostatic Hypotension (nOH)
MSA is a progressive brain disorder that affects movement and balance and disrupts the function of the autonomic nervous system.

One of the most frequent autonomic symptoms associated with MSA is a sudden drop in blood pressure upon standing (nOH).4 There are approximately 50,000 MSA patients in the US1 and 70
Neurogenic orthostatic hypotension (nOH) is a rare disorder defined as a fall in systolic blood pressure of ⩾20 mm Hg or diastolic blood pressure of ⩾10 mm Hg, within 3 minutes of standing. Severely affected patients are unable to stand for more than a few seconds because of their decrease in blood pressure, leading to cerebral hypoperfusion and syncope. A debilitating condition, nOH results in a range of symptoms including dizziness, lightheadedness, fainting, fatigue, blurry vision, weakness, trouble concentrating, and head and neck pain.
