Cerebellar Ataxia

Cerebellar Ataxia is caused by lesions of the cerebellum region of the brain or the connections to it in the cerebellar peduncles, the pons or the red nucleus.

Cerebellar Ataxia is a relatively common symptom of multiple sclerosis but is also associated with other conditions. These include an idiopathic (cause unknown) condition most usually in children which often follows a viral infection such as chicken pox and a genetic condition known as Miller Fisher Syndrome.

In Cerebellar Ataxia, afferent nerve transmissions to the cerebellum are disturbed which affects coordination and muscle reactions. The symptoms include:

Lesions of the midline vermis and fastigial nuclei often result in nystagmus, gait ataxia and unstable stance. The most severe disturbances are produced by lesions of the superior cerebellar peduncle and the deep nuclei.
