(1) Epilepsy (seizure disorder): When nerve cells in the brain fire electrical impulses at a rate of up to four times higher than normal, this causes a sort of electrical storm in the brain, known as a seizure. A pattern of repeated seizures is referred to as epilepsy. Known causes include head injuries or trauma, brain tumors, lead poisoning, maldevelopment of the brain, genetic and infectious illnesses. But in fully half of cases, no cause can be found. Medication controls seizures for the majority of patients.

(2) Epilepsy is a seizure disorder. A seizure is an event that involves loss of consciousness and motor (muscular) control. A person with a seizure disorder often experiences repetitive muscle jerking called convulsions. The condition is caused by a sudden change in electrical activity in the brain.
