Other nervous system structures are usually affected, including the basal ganglia, brainstem nuclei, pyramidal tracts, and posterior column and anterior horn of the spinal cord, as well as the peripheral nerves. SCAs are clinically characterized by the presence of cerebellar gait, limb ataxia (with dysmetria,dysdiadochokinesia, intention tremor), scanning dysarthria, dysphagia, nystagmus, and ocular motility abnormalities, which may be accompanied by extracerebellar signs such as ophthalmoplegia, pyramidal signs, movement disorders (including parkinsonism, dystonia, myoclonus, and chorea), dementia, epilepsy, visual disorders (including pigmentary retinopathy), lower motor neuron dise
