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]
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 involving only part of the body with variable levels of consciousness (focal seizure), to a subtle momentary loss of awareness ...
Focal seizures (also called partial seizures[1] and localized seizures) are seizures that affect initially only one hemisphere of the brain. [2][3] The brain is divided into two hemispheres, each consisting of four lobes – the frontal, temporal, parietal and occipital lobes. A focal seizure is generated in and affects just one part of the ...
A seizure is a paroxysmal episode of symptoms or altered behavior arising from abnormal excessive or synchronous brain neuronal activity. [5] A focal onset seizure arises from a biological neural network within one cerebral hemisphere, while a generalized onset seizure arises from within the cerebral hemispheres rapidly involving both hemispheres.
Neurology, Psychiatry. 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 ...
Generally, seizures are observed in patients who do not have epilepsy. [ 1 ] There are many causes of seizures. Organ failure, medication and medication withdrawal, cancer, imbalance of electrolytes, hypertensive encephalopathy, may be some of its potential causes. [ 2 ] The factors that lead to a seizure are often complex and it may not be ...
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 ...
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 ...
