Definition

A seizure is a sudden abnormal event involving uncontrollable muscle movement or mental confusion, possibly including alteration in consciousness. Seizures may be single or multiple. They typically last only from a few seconds to several minutes and are followed by a period of confusion that may last for hours.

Causes

Seizures occur due to the excessive and uncontrolled electrical activity of brain cells (neurons).

Treatment

The individual needs immediate care by medical personnel. Tests such as a CT scan and electroencephalography (EEG) may be performed to determine the cause of the seizure. Sometimes seizures are treated with medication other times no treatment is necessary.

Comments

Seizures are not usually fatal. In rare situations, seizures do not stop and require ongoing medical care.
