Multiple-system atrophy (MSA) is a degenerative neurological disorder. MSA is associated with the degeneration of nerve cells in specific areas of the brain. This cell degeneration causes problems with movement balance and other autonomic functions of the body such as bladder control or blood-pressure regulation. The cause of MSA is unknown and no specific risk factors have been identified. Around 55% of cases occur in men with typical age of onset in the late 50s to early 60s.
