DefinitionBy Mayo Clinic Staff
Multiple system atrophy (MSA) is a rare neurological disorder that impairs your body's involuntary (autonomic) functions, including blood pressure, heart rate, bladder function and digestion.
Formerly called Shy-Drager syndrome, the condition shares many Parkinson's disease-like symptoms, such as slowness of movement, muscle rigidity and poor balance.
Multiple system atrophy is a degenerative disease that develops in adulthood, usually in the 50s or 60s.
Treatment for MSA includes medications and lifestyle changes to help manage symptoms. The condition progresses gradually and eventually leads to death.
