Cerebellar involvement and stimulation in epilepsy
April 2026 | Current Opinion in Neurology
Purpose of review
This review discusses the current state of the evidence related to the relationship between the cerebellum and epilepsy, highlighting evidence on neurostimulation of the cerebellum for treatment of epilepsy, and placing current knowledge into historical context.
Recent findings
The cerebellum plays an important role in certain epilepsy types, both as a key part of epileptic networks and an area that can give rise to seizures. Cerebellar stimulation as a potential treatment for drug-resistant epilepsy is a recurring, albeit niche, topic of interest. Over decades of intermittent, often highly limited investigations into this area of research, there are still more questions than answers. However, more recent preclinical insights point the way towards leveraging modern surgical techniques and technology in investigating cerebellar stimulation as a potential viable treatment approach to select types of epilepsy.
Summary
Cerebellar stimulation holds promise for improving seizure control in people with specific types of drug-resistant epilepsy. Future studies should leverage new preclinical data, along with modern technology, neurosurgical techniques, and clinical trial design, to help determine the optimal stimulation parameters, optimal stimulation targets, and optimal patient-selection for this promising area of investigation.
