Multiple system atrophy - cerebellar subtype (MSA-C) is a rare disease that causes areas deep in the brain, just above the spinal cord, to shrink (atrophy). MSA-C used to be known as olivopontocerebellar atrophy (OPCA).

MSA-C can be passed down through families (inherited form). It can also affect people without a known family history (sporadic form).
Researchers have identified certain genes that are involved in the inherited form of this condition.
The cause of MSA-C in people with the sporadic form is not known. The disease slowly gets worse (is progressive).
MSA-C is slightly more common in men than in women. The average age of onset is 54 years old.
Symptoms of MSA-C tend to start at a younger age in people with the inherited form. The main symptom is clumsiness (ataxia) that slowly gets worse. There may also be problems with balance, slurring of speech, and difficulty walking.
Other symptoms may include:
There is no specific treatment or cure for MSA-C. The aim is to treat the symptoms and prevent complications. This may include:
The following groups can provide resources and support for people with MSA-C:
MSA-C slowly gets worse, and there is no cure. The outlook is generally poor. But, it may be years before someone is very disabled.
Complications of MSA-C include:
Call your health care provider if you have any symptoms of MSA-C. You will need to be seen by a neurologist. This is a doctor who treats nervous system problems.
