Patients with epileptic automatism present with sudden onset of seizures, dazed gaze, and purposeless automatic movements such as sticking out the tongue, chewing, walking, running, undressing, moving objects, and mumbling. The clinical diagnosis of the disease is complicated. In addition to the clinical symptoms, relevant auxiliary examinations are required to confirm the diagnosis. EEG: In principle, the EEG during seizures is one of the most valuable auxiliary examinations. However, the conventional scalp EEG used in clinical practice may not always be recorded, and the total positive rate is only about 80% to 90% during the interictal period even when combined with the evocation test and 24-hour continuous tracing. Therefore, the clinical diagnosis must be combined with medical history, physical examination and other aspects of the comprehensive analysis, not because the EEG is negative to deny that it is epilepsy, of course, no clinical manifestations and a positive EEG, but also can not confirm the diagnosis. As long as the clinical manifestations are typical, the diagnosis can generally be made, and attention should be paid to strengthen the examination of EEG. Imaging: Except for identified primary epilepsy and epilepsy syndromes that do not require neuroimaging, this examination should be done. It should be noted that imaging is not in itself diagnostic of epilepsy, but is intended to clarify the etiology and location of the disease as well as to treat the cause and estimate the prognosis. 3, blood chemistry examination: such as blood glucose, blood calcium, blood magnesium, composition, etc. The level of blood glucose, blood calcium and blood magnesium concentration is an important condition that causes seizures. On the one hand, the abnormality of these factors may be an important factor to cause seizures, on the other hand, it can provide a basis for the diagnosis of some diseases with seizures, such as hypoparathyroidism epilepsy, diabetic epilepsy, etc. The main purpose of the composition determination is to guide the clinical use, including the selection of a good role and determine the accurate dose. 4, urine examination: mainly for some genetic metabolic diseases, such as phenylketonuria.
