Spinocerebellar ataxia type 1 (SCA1): new pathoanatomical and clinico‐pathological insights

Abstract

These findings show for the first time that the extent and severity of brain damage in SCA1 is very similar to that of clinically closely related spinocerebellar ataxias (that is, SCA2, SCA3 and SCA7). They offer suitable explanations for poorly understood SCA1 disease symptoms and will facilitate the interpretation of further morphological and experimental SCA1 studies.
