What sort of disorder is epilepsy?

Unprovoked Seizures. Epilepsy is a constellation of disorders with a common definition: the tendency toward recurrent, unprovoked seizures. The term "epilepsy' applies to anyone who has had more than one unprovoked seizure. Seizures, however, can take on many forms; from staring off for a few seconds, to prolonged, violent convulsions. Epilepsy is simply a word that tells us a patient has recurrent seizures.
