Epilepsy: Tonic Seizures - Topic Overview

Tonic seizures are fairly uncommon. They occur mostly in people with Lennox-Gastaut syndrome. This is a severe form of generalized epilepsy that begins in early childhood. (Children with Lennox-Gastaut syndrome may also have atonic seizures.)

When a tonic seizure occurs, the muscles in the body contract and the entire body stiffens. This occurs suddenly and without warning. And it often causes the person to fall down.
