Epilepsy is brain disorder caused by abnormal brain activity.
Epilepsy is brain disorder in which patients have seizures, caused by abnormal brain activity. Traditionally, people think of a seizure as complete body shaking with unconsciousness. This is a type of seizure called a generalized tonic-clonic, or grand mal, seizure. There are other types of seizures though too. Simple partial seizures can just involve an abnormal taste, abnormal smell, focal hand shaking or abnormal sensation. Absence seizures may involve being awake, but somewhat unaware of one’s surroundings or “daydreaming”.
