Multiple system atrophy (MSA) is a rare condition that gradually damages the nerve cells in the brain. It affects your balance, blood pressure, breathing, digestion, bladder control, movement, and more.
Symptoms of MSA usually start to appear when a person is in their 50s or 60s. There are many possible symptoms, so not everyone will have all symptoms.
Currently, the cause of MSA is unknown.
There's no cure for MSA and no way to slow down the symptoms. Most people with MSA will live for about six to nine years after their symptoms stat. For many people, symptoms can quickly get worse, but they can be managed with medication, physical therapy, and other interventions.
