Cerebellar dysfunction in patients with epilepsy can result from genetic disorders, antiseizure medications, seizures, and seizure\u2010related trauma. Impaired cerebellar function, regardless of cause, can cause ataxia (imbalance, impaired coordination, unsteady gait), tremor, gaze\u2010evoked nystagmus, impaired slow gaze pursuit and saccade accuracy, as well as speech deficits (slurred, scanning, or staccato). We explore how cerebellar dysfunction can contribute to epilepsy, reviewing data on genetic, infectious, and neuroinflammatory disorders. Evidence of cerebellar dysfunction in epilepsy comes from animal studies as well as human neuropathology and structural magnetic resonance imaging (MRI), functional and diffusion tensor MRI, positron emission and single photon emission computerized tomography, and depth electrode electro\u2010encephalography studies. Cerebellar lesions can infrequently cause epilepsy, with focal motor, autonomic, and focal to bilateral tonic\u2013clonic seizures. Antiseizure medication\u2013resistant epilepsy typically presents in infancy or before age 1 year with hemifacial clonic or tonic seizures ipsilateral to the cerebellar mass. Lesions are typically asymmetric benign or low\u2010grade tumors in the floor of the fourth ventricle involving the cerebellar peduncles and extending to the cerebellar hemisphere. Electrical stimulation of the cerebellum has yielded conflicting results on efficacy, although methodological issues confound interpretation. Epilepsy\u2010related comorbidities including cognitive and affective disorders, falls, and sudden unexpected death in epilepsy may also be impacted by cerebellar dysfunction. We discuss how cerebellar dysfunction may drive seizures and how genetic epilepsies, seizures and seizure therapies may drive cerebellar dysfunction, and how our understanding of epilepsy\u2010related comorbidities through basic neuroscience, animals models and patient studies can advance our understanding and improve patient outcomes.<\/jats:p>","DOI":"10.1111\/epi.18316","type":"journal-article","created":{"date-parts":[[2025,3,13]],"date-time":"2025-03-13T10:49:07Z","timestamp":1741862947000},"page":"1773-1792","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["The
