Epilepsy is a disorder which takes the form of recurring seizures.
Seizures are sudden uncontrolled episodes of electrochemical activity in the brain.
Brain cells normally communicate with each other in a coordinated way to control our conscious state and body movements. During a seizure this communication is temporarily disturbed and becomes uncoordinated. There are many different types of seizures. Although they can sometimes look frightening, they rarely cause any damage to the brain. Most epilepsy can be effectively treated.
