Seizures cause the brain to malfunction, resulting in unconsciousness, convulsions, uncontrolled movement, or changes in behavior. A person with epilepsy suffers from recurrent seizures.

Types of seizures include:

• Febrile seizure
• Grand-mal seizure
• Petit-mal seizure
• Psychomotor seizure
• Partial seizures:
• Simple partial seizures
• Complex partial seizures
