Epilepsy is a brain condition that causes unprovoked seizures. During a seizure, a person may experience loss of consciousness, convulsions, or abnormal behavior.
Epilepsy has many causes, including:
- brain damage from prenatal or perinatal causes
- congenital abnormalities or genetic conditions
- head injury
- an infection of the brain such as meningitis, encephalitis or neurocysticercosis
- brain tumor
Children and older adults are more likely to have epilepsy.
