Abstract
The classification of tonic seizures falls under the “generalized” seizure category, implying an alteration of consciousness, and originating bilaterally. Tonic seizures are usually short duration (less than 1 min), and characterized by rapid onset, and increased muscle tone in extensor muscles. This causes a fall if the patient is not seated. Postictal depression is common, with associated headache and confusion. Tonic seizures are a frequent feature of the Lennox–Gastaut syndrome, along with other seizure types. The Lennox–Gastaut syndrome represents as many as 4% of all childhood epilepsies (Kramer et al. 1998). Tonic seizures are the most prevalent seizure type in Lennox–Gastaut syndrome, accounting for more than one-half of seizures (Aicardi 1988).
