Pathological superfluous examination is mainly found by talking and chatting with the patient, etc. If pathological superfluous tendency is found, at the same time, EEG, cranial CT, cranial MRI and other examinations should be improved to understand whether the brain activity is normal. 1.Electroencephalography: It is a method to check the brain function by magnifying the spontaneous bioelectricity of the brain and showing or recording it. It is a means of examining brain function that cannot be replaced by CT and MRI, and is scientific, safe and non-invasive. 2.Brain topography: It can visually understand the distribution of brain waves. 3.CT examination of the skull: it is a method to examine the skull through CT. Cranial CT is a new examination method which is convenient, rapid and safe, painless and non-invasive. It can clearly show the anatomical relationship of different cross-sections of the cranial brain and the specific brain tissue structure. Thus, it greatly improves the detection rate and diagnostic accuracy of lesions. 4.Cranial MRI examination: It is an MRI examination of the brain, which is used to observe whether there are lesions in the brain and can clarify whether the patient is caused by structural changes in the brain.
