Status epilepticus ( SE ), or status seizure, is a medical condition consisting of a single seizure lasting more than 5 minutes, or 2 or more seizures within a 5-minute period without the person returning to normal between them. [3] [1] Previous definitions used a 30-minute time limit. [2] The seizures can be of the tonic–clonic type, with a ...
Specialty. Neurology, psychiatry. Psychogenic non-epileptic seizures ( PNES ), also referred to as pseudoseizures, non-epileptic attack disorder ( NEAD ), functional seizures, or dissociative seizures, [2] [3] are episodes resembling an epileptic seizure but without the characteristic electrical discharges associated with epilepsy.
140,000 (2021) [9] Epilepsy is a group of non-communicable neurological disorders characterized by recurrent epileptic seizures. [10] An epileptic seizure is the clinical manifestation of an abnormal, excessive, and synchronized electrical discharge in the neurons. [1] The occurrence of two or more unprovoked seizures defines epilepsy. [11]
In the field of neurology, temporal lobe epilepsy is an enduring brain disorder that causes unprovoked seizures from the temporal lobe. Temporal lobe epilepsy is the most common type of focal onset epilepsy among adults. [1] Seizure symptoms and behavior distinguish seizures arising from the medial temporal lobe from seizures arising from the ...
Frequency. ~10% of people (overall worldwide lifetime risk) [5] [9] A seizure is a period of symptoms due to abnormally excessive or synchronous neuronal activity in the brain. [6] Outward effects vary from uncontrolled shaking movements involving much of the body with loss of consciousness ( tonic-clonic seizure ), to shaking movements ...
A generalized tonic–clonic seizure, commonly known as a grand mal seizure or GTCS, [1] is a type of generalized seizure that produces bilateral, convulsive tonic and clonic muscle contractions. Tonic–clonic seizures are the seizure type most commonly associated with epilepsy and seizures in general and the most common seizure associated ...
Neurology. Generalized epilepsy is a form of epilepsy characterised by generalised seizures with no apparent cause. [1] Generalized seizures, as opposed to focal seizures, are a type of seizure that impairs consciousness and distorts the electrical activity of the whole or a larger portion of the brain (which can be seen, for example, on ...
In the UK and Sweden, the relative mortality rate of epileptic patients (patients whose epilepsy was not under control from medical or other surgical therapies and who continued to have the disease) increased two- and threefold, respectively. In the vast majority of cases, corpus callosotomy abolishes instance of seizures in the patient.
