Epilepsy, commonly known as crohn’s disease, is a chronic disorder in which the brain is overly discharged, causing recurrent sudden onset, transient abnormalities in brain function. Seizures mostly manifest as symptoms of brain stimulation and abnormal reactions in motor, sensory, autonomic and cognitive, emotional or behavioral areas. The understanding of epilepsy went through a tortuous process until 1861, when the British physician Jackson first pointed out from an electrophysiological perspective that seizures originate from a part of the gray matter of the brain that produces an abnormal, intense, short-lived electrical emission, as opposed to the clinical seizure-interval- -recurrence of interictal-interictal periods, an abnormal discharge of the brain. Since then, through the efforts of many researchers and clinical scholars and the research and application of EEG examination instruments, progress has been made in the mechanism of epilepsy, developmental process, clinical manifestations and classification, and EEG changes, which are the basis of scientific understanding of epilepsy. Epilepsy is a clinical syndrome caused by different etiologies and pathologies, and its common manifestations are short, intense and sudden seizures. There are many different clinical manifestations of seizures due to different sites of pathology, such as the presence of motor, one-show sensory, special sensory, visceral, and psychological seizure abnormalities.
