Cerebellar ataxia is a form of ataxia originating in the cerebellum.[1] Spinocerebellar ataxia (SCA) is a progressive, degenerative,[1] genetic disease with multiple types, each of which could be considered a disease in its own right. Ataxia (from Greek ¦Á- [used as a negative prefix] [order], meaning "lack of order") is a neurological sign and symptom consisting of gross lack of coordination of muscle movements. Ataxia is a non-specific clinical manifestation implying dysfunction of parts of the nervous system that coordinate movement, such as the cerebellum. Several possible causes exist for these patterns of neurological dysfunction. The term "dystaxia" is rarely used as a synonym.
