Seizure A seizure is a sudden change in the brain's normal electrical activity. During a seizure, brain cells fire uncontrollably at up to four times their normal rate, temporarily affecting the way a person behaves, moves, thinks or feels. There are two major types of seizures: 1  Primary generalized seizures – The seizure affects the entire cerebral cortex, the outer portion of the brain that contains the majority of brain cells. 2  Partial (focal) seizure – The abnormal firing of brain cells begins in one region of the brain and remains in that one region.

- Email Article. Epilepsy is a disorder of recurring seizures. Seizures are described as an uncoordinated firing of the neurons usually within a portion of the brain called the cerebrum. The mechanisms of why these neurons do not function normally in epileptic cats is not understood, but is similar if not identical to the causes in humans.

Epileptic seizure An epileptic seizure (colloquially a fit) is a brief episode of signs or symptoms due to abnormal excessive or synchronous neuronal activity in the brain. The outward effect can vary from uncontrolled jerking movement (tonic-clonic seizure) to as subtle as a momentary loss of awareness (absence seizure). Diseases of the brain characterized by an enduring predisposition to generate epileptic seizures are collectively called epilepsy.

A seizure happens when abnormal electrical activity in the brain causes an involuntary change in body movement or function, sensation, awareness, or behavior.ome people have only one type of seizure, while others have more than one type. Epilepsy is referred to as a spectrum disorder because seizure types, frequency, and other symptoms can vary. Epilepsy can be caused by many different conditions that affect a person’s brain.
