Spinocerebellar ataxia (SCA), also known as spinocerebellar atrophy or spinocerebellar degeneration, is a progressive, degenerative, genetic disease with multiple types, each of which could be considered a neurological condition in its own right. An estimated 150,000 people in the United States have a diagnosis of spinocerebellar ataxia at any given time.

Diagnosis Five years after becoming symptomatic, the patient was re-evaluated for a possible genetic ataxia syndrome, which was subsequently confirmed by gene testing as spinocerebellar ataxia type 6.

ATAXIA AND CEREBELLAR DEGENERATION. Ataxia can be caused by lesions that interrupt the sensory input to the cerebellum (spinal or sensory ataxia), pathology of the cerebellar cortex resulting in incorrect execution of cortical signals (cerebellar ataxia), or by a combination of both (spinocerebellar ataxia).In terms of genetics, ataxias can be divided into 3 groups listed below.
