Seizure

An epileptic seizure, occasionally referred to as a fit, is defined as a transient symptom of "abnormal excessive or synchronous neuronal activity in the brain".

What is a Seizure?

Seizures are caused by abnormal electrical activity in the brain. In the healthy brain, electrical and chemical signals are fired between nerves called neurons to drive the brain's ability to think, feel and send instructions to parts of the body, such as the muscles. Seizures occur when this electrical system in the brain malfunctions.
