CAUSES

Epilepsy is a chronic neurological disorder in which clusters of nerve cells or neurons in the brain sometimes signal abnormally and cause seizures. There are diverse causes and mechanisms of disease development, but globally in about 50% of cases, the cause is still unknown. In other cases, epilepsy causes can be described as: structural, genetic, infectious, metabolic and immune.
