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.
Diagnosis of epilepsy can be difficult. A number of other conditions may present very similar signs and symptoms to seizures, including syncope, hyperventilation, migraines, narcolepsy, panic attacks and psychogenic non-epileptic seizures (PNES). [134] [135] In particular, syncope can be accompanied by a short episode of convulsions. [136]
A brain injury can cause seizure(s) because of the unusual amount of energy that is discharged across of the brain when the injury occurs and thereafter. A disruption of the supply of oxygen may cause damage to the temporal lobe of the brain. [35] The risk of seizure(s) from a closed head injury is about 15%. [36]
A simple febrile seizure is generalized, occurs singularly, and lasts less than 15 minutes. [19] A complex febrile seizure can be focused in an area of the body, occur more than once, and lasts for more than 15 minutes. [19] Febrile seizures affect 2–4% of children in the United States and Western Europe, it is the most common childhood ...
In addition to being a warning sign for an impending seizure, the nature of an aura can give insight into the localization and lateralization of the seizure or migraine. [4] [5] The most common auras include motor, somatosensory, visual, and auditory symptoms. [6]
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.
