Overview

Multiple system atrophy (MSA) is a rare, degenerative neurological disorder affecting your body's involuntary (autonomic) functions, including blood pressure, breathing, bladder function and motor control.

Formerly called Shy-Drager syndrome, olivopontocerebellar atrophy or striatonigral degeneration, MSA shares many Parkinson's disease-like symptoms, such as slow movement, rigid muscles and poor balance.

Treatment includes medications and lifestyle changes to help manage symptoms, but there is no cure. The condition progresses gradually and eventually leads to death.
