Cerebellar dysfunction is a collective term used to describe hereditary or acquired conditions impacting one or more cerebellar hemispheres.1 Cerebellar dysfunction can result from many diagnoses, including spinocerebellar ataxias, acquired brain injury, Parkinson disease (PD), Huntington disease (HD), multiple sclerosis (MS), metabolic disorders, and chronic toxin exposure.1-6 Because of the cerebellum's role in integrating sensory information and motor output, a wide variety of motor control deficits can result from cerebellar dysfunction.7-10 In addition to these more commonly known deficits, the cerebellum also plays an important role in emotion and cognition, resulting in deficits collectively known as cerebellar cognitive affective syndrome (CCAS).1,7-10
