Imaging in neurodegenerative disorders.

This article discusses imaging findings of the cortical and subcortical neurodegenerative diseases. Spinocerebellar ataxia and neurodegenerative diseases secondary to vascular insults (multiinfarction dementia, Binswanger's disease, cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy, and amyloid angiopathy) are beyond the scope of this discussion.
