Chapter 23: Seizures and EpilepsyBACKGROUND23.1 About seizures and epilepsySeizuresA seizure is caused by a sudden electrical discharge in the brain. A seizure does not alwaysmean that a person falls to the ground in convulsions. It can be manifested in various ways,including: feelings of being absent visual distortions nausea vertigo tingling twitching shaking rigidity of parts of the body or the entire body, or an alteration or loss of consciousness.Seizures may occur in people who do not have epilepsy. These non-epileptic seizures are oftenreferred to as provoked seizures. Some are caused by transient factors with no structural brainabnormality such as: fever low blood sugar electrolyte imbalance head trauma meningitis simple fainting, and alcohol or drug toxicity or withdrawal.Others are caused by conditions where there is a structural brain abnormality such as a: tumour stroke aneurysm, or hematoma.Provoked seizures are not epilepsy, and they resolve after the provoking factor has resolved orstabilized.Sometimes people appear to have seizures, even though their brains show no seizure activity.This phenomenon is called a non-epileptic psychogenic seizure (NEPS), sometimes referred to as299
