A tonic seizure causes a sudden stiffness or tension in the muscles of the arms, legs or trunk. The stiffness lasts about 20 seconds and is most likely to happen during sleep. Tonic seizures that occur while the person is standing may cause them to fall. After the seizure, the person may feel tired or confused. Tonic Seizure also called Grand Mal Seizure.
A grand mal seizure is usually caused by epilepsy, but may have other triggers, such as very low blood sugar, high fever or a stroke. Many people will have only one such seizure in their lifetime. Others may need daily anti-seizure medication to prevent recurrence.
