Ataxia - StatPearls - NCBI Bookshelf
网页2023年8月23日 · Pathophysiology. Ataxia may be due to an interference in the sensory transmission to the cerebellum caused by a lesion. This condition can lead to sensory or spinal ataxia. An interruption in cortical signals from the cerebellum causes cerebellar ataxia. Spinocerebellar ataxias are a result of both of the above mentioned pathologies.
