In the field of neurology, seizure types are categories of seizures defined by seizure behavior, symptoms, and diagnostic tests. The International League Against Epilepsy (ILAE) 2017 classification of seizures is the internationally recognized standard for identifying seizure types. [ 1 ]
distinguish epileptic seizures from other types of spells, such as psychogenic non-epileptic seizures, syncope (fainting), sub-cortical movement disorders and migraine variants; differentiate "organic" encephalopathy or delirium from primary psychiatric syndromes such as catatonia; serve as an adjunct test of brain death in comatose patients
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]
There have been early and consistent strategies for measurement to better understand vertiginous epilepsy including caloric reflex test, posture and gait, or rotational experimentation. [9] In Japan, Kaga et al prepared a longitudinal study of rotation tests comparing congenital deafness and children with delayed acquisition of motor system skills.

Abnormally excessive or synchronous neuronal activity in the brain can cause seizures. These symptoms are characteristic of the neurological disorder known as epilepsy. Epilepsy is typically diagnosed with an EEG test. [6] However, the effectiveness of MEG in the diagnosis of neocortical epilepsy has also been established. [7]
A seizure is a sudden change in behavior, movement or consciousness due to abnormal electrical activity in the brain. [3] [6] Seizures can look different in different people.. It can be uncontrolled shaking of the whole body (tonic-clonic seizures) or a person spacing out for a few seconds (absence seizure
Neuroimaging tests may identify the cause for seizures and the seizure focus, the brain location where seizures begin. [4] In newly diagnosed epilepsy, magnetic resonance imaging (MRI) can detect brain lesion in up to 12 to 14% of persons with epilepsy. [31]
