A convulsion is a medical condition where the body muscles contract and relax rapidly and repeatedly, resulting in uncontrolled shaking. [1] Because epileptic ...
Seizure prediction is a special case of seizure detection in which the developed systems is able to issue a warning before the clinical onset of the epileptic seizure. [76] [78] Computational neuroscience has been able to bring a new point of view on the seizures by considering the dynamical aspects. [79]
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]
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]
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 electroencephalography, EEG).
Convulsions are induced in captive animals, then high doses of anticonvulsant drugs are administered. [ 10 ] [ 11 ] [ 12 ] For example, kainic acid can lead to status epilepticus in animals as it is a cyclic analog of l-glutamate and an agonist for kainate receptors in the brain which makes it a potent neurotoxin and excitant.
Infantile epileptic spasms syndrome (IESS) previously known as West syndrome needs the inclusion of epileptic spasms for diagnosis. [1] Epileptic spasms (also known as infantile spasms) may also occur outside of a syndrome (that is, in the absence of hypsarrhythmia and cognitive regression) - notably in association with severe brain disorders (e.g. lissencephaly).
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.
