Seizure clusters.

Acute repetitive seizures, also called seizure clusters, are common phenomena in patients with epilepsy. They are a burden on patients and their caregivers and may be very disruptive to the patients' lives. They may progress to prolonged seizures or status epilepticus if they are not aborted as soon as possible. However, their definition, recognition, and classification still suffer from a lack of consensus among healthcare professionals in the field. This review aims to shed light on various aspects of seizure clusters with particular attention to their treatments.
