Cerebellar ataxia refers to impaired coordination caused by cerebellar dysfunction, often manifesting with gait instability, limb incoordination, dysarthria, oculomotor abnormalities, and impaired motor timing.[1][2] It is a syndromic destination for many NeuroWiki pages involving cerebellar cell types, hereditary ataxia genes, and degenerative circuitry.
Cerebellar ataxia is not a single disease but an important phenotype across spinocerebellar disorders, multiple system atrophy, mitochondrial disease, and other degenerative syndromes.[1:1][2:1] It therefore functions as a shared clinical endpoint linked to cerebellar-function and cerebellar cell-type pages.
