Epilepsy is commonly known as “crohn’s disease” or “sheep epilepsy”, which is a chronic disease caused by abnormal discharge of neurons in the brain, resulting in transient brain dysfunction. The patient’s physical and mental health is seriously endangered, affecting the patient’s normal life, and also affecting the patient’s intellectual development. Before treatment, it is important to do a good examination. EEG is the most effective diagnostic aid for amniotic stroke diagnosis. So, what are the precautions for amniotic EEG examination? Experts tell you! 1, external stimulation and mental activity: brain wave rhythm is generally susceptible to the influence of mental activity, such as when the subject will focus on something or do mental arithmetic, the alpha rhythm is suppressed, to low amplitude beta wave, and the stronger the mental activity, the more obvious the alpha wave suppression effect, external stimulation can also cause the same changes. This is why the surrounding environment should be quiet when doing EEG, and the subject should relax and not think about the problem. 2, age and individual differences: EEG, as an important aspect to objectively reflect the functional state of the brain, is very closely related to age. For example, in pediatric patients, EEG can observe changes in brain wave development with increasing age. The brain waves can show significant differences depending on the age stage. On the other hand, the abnormal wave pattern varies due to the different age of brain excitation in the pediatric period, especially in the case of amniotic stroke. In adulthood, the brain waves gradually stabilize, and after middle age, as brain function gradually decreases, the brain waves produce corresponding changes. In old age, due to ischemic brain damage or the presence of brain atrophy, most will also have meaningful brain wave abnormalities. 3, the state of consciousness: EEG can reflect the changes in the level of consciousness awakening, if adults appear sleepy in the awakening state, EEG from the alpha wave dominant graphics appear amplitude reduction, and soon shift to the ripple state. After sleep, the change of brain waves will be further obvious and roughly parallel to the depth of sleep. In the pathological state, the abnormalities of EEG waveforms are related to the cause and extent of the disease, and some other abnormal wave patterns can be seen in addition to the majority of widespread or diffuse waves. These abnormal wave patterns are often used clinically to infer the cause and extent of the disorder, and to determine the location of the disorder.
