Spinocerebellar ataxia

Spinocerebellar ataxias comprise a large (and expanding) group of diseases characterised by degeneration of the spinal cord and cerebellum. 

There are well over 25 individual spinocerebellar ataxias referred to sequentially as SCA1, SCA2 ... in order of their discovery and genetic characterisation. 

Radiographic features

Although individual spinocerebellar ataxias vary in morphological changes, atrophy of the cerebellum is a relatively constant finding. Extracerebellar regions are also affected, depending on the specific SCA.1 


Neurodegenerative diseases

Neurodegenerative diseases are legion and their classification just as protean. A useful approach is to divide them according to underlying pathological process, although even using this schema, there is much overlap and thus resulting confusion.
