Cerebellar atrophy, technically speaking, is not a disease but a neuroimaging finding. It can be observed in various genetic or degenerative conditions, as well as in certain acute conditions such as late-stage acute cerebellitis and some cases of drug toxicity. Additionally, it can be seen in clinically asymptomatic individuals, particularly in the elderly population. The common feature is a reduction in the volume of the cerebellum and widening of the cerebellar fissures observed on neuroimaging. Cerebellar atrophy can be either focal or widespread. Since the cerebellum plays a crucial role in regulating body balance and muscle tone, patients with cerebellar atrophy often exhibit symptoms such as unsteady gait, ataxia, and slurred speech.
