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.People who have tonic or atonic seizures are likely to be injured when they fall. Children may have to wear helmets and restrict their activities to prevent serious injury.

Epilepsy: Generalized Tonic-Clonic Seizures - Topic Overview
Generalized tonic-clonic (grand mal) seizures are the easiest seizures to recognize. They happen most often in people with generalized epilepsy of unknown cause.A generalized tonic-clonic seizure begins with a sudden loss of consciousness. During the first 15 to 30 seconds of the seizure, the entire body stiffens as the muscles contract. The back and neck are arched. Sometimes the person may cry out as the vocal cords contract and air is released from the lungs. The person may turn blue because he or she isn't breathing. This is the tonic phase of the seizure.During the next 30 to 45 seconds, the muscles jerk (convulse) in a rhythmic pattern. This is the clonic phase of the seizure. While the muscles are jerking, the person may bite his or her tongue or lose bladder or bowel control.An entire seizure lasts 1 to 2 minutes.

Hemispherectomy for Epilepsy - Topic Overview
The left and right sides of the brain are called hemispheres. Hemispherectomy is the removal of one side of the brain. This procedure is sometimes done on children who have severe forms of epilepsy, such as Rasmussen syndrome and Sturge-Weber disease. These conditions badly damage one side of the brain, cause frequent seizures and problems with physical and mental development. And these conditions do not respond well to drug treatment.Hemispherectomy may completely prevent seizures and reverse delays in development that occur with some forms of epilepsy.The surgery always causes some loss of movement and sensation on one side of the body and sometimes causes partial loss of vision in half of the visual field of each eye. But most children with a large epileptic area on one side of the brain already have these problems before the surgery.
