What is Sporadic Ataxia?
There is a large group of people who have symptoms of ataxia that usually begin in adulthood and who have no known family history of this disease. This is called sporadic ataxia and it can be difficult to diagnose. There are many acquired and hereditary causes of ataxia which must be ruled out before a diagnosis of sporadic ataxia can be made. Sporadic ataxia can be either “pure cerebellar” if only the cerebellum is affected or cerebellar plus, if the ataxia is accompanied by additional symptoms such a neuropathy (dysfunction of the peripheral nerves); dementia (impaired intellectual function); or weakness, rigidity, or spasticity of the muscles. Disability may be greater and progress more quickly with the cerebellar plus form of sporadic ataxia. The cerebellar plus form of sporadic ataxia is also known as sporadic olivopontocerebellar ataxia ( sporadic OPCA) or multiple system atrophy, cerebellar type (MSA-C).
