Cerebellar ataxia is a form of ataxia originating in the cerebellum. (wikipedia.org)
GAD65 is involved in the synthesis, packaging, and release of GABA, whereas the other three play important roles in the induction of long-term depression (LTD). Thus, the auto-antibodies toward these synaptic molecules likely impair fundamental synaptic machineries involved in unique functions of the cerebellum, potentially leading to the development of cerebellar ataxias (CAs).

Autoimmunity affects the cerebellum, leading to the manifestations of the cerebellar ataxias (CAs), termed immune-mediated cerebellar ataxia (IMCAs). (springer.com)
These findings suggest that the neurological underpinnings in PD, manganism, and WF-mediated PD-like manifestation encompasses much more than degeneration of the nigrostriatal dopaminergic pathway and involves brain areas associated with sensorimotor, fine motor, and cognitive tasks, such as the cortex, thalamus, and cerebellum.

Their impacts are probably mediated by their effects on the cerebellum, where they have numerous receptors. (myasiancruise.com)
