Multiple System Atrophy

Multiple system atrophy (MSA) is a rare degenerative condition that causes symptoms similar to Parkinson’s disease. However, patients with MSA have more widespread damage to the part of the nervous system that controls involuntary functions. Also known as Shy-Drager syndrome, MSA develops gradually and is most often diagnosed in men older than 60. The disease is characterized by: progressive damage to the nervous system, leading to low blood pressure when standing, difficulty urinating, abnormal breathing during sleep, muscle tremor and rigidity, and slow movement.

Other symptoms include dizziness, impotence, blurred vision, walking pattern changes, and changes in facial expression, as well as depression, confusion and dementia. The cause is unknown. Neurological and other tests are used to confirm the diagnosis. The goal of treatment is to control symptoms.
