summary

For a long time, my grandfather always felt dizzy and sometimes lost his mind. Although he was old and had poor memory, his family still didn't feel at ease and gave him EEG. Today, let me talk about the side effects of EEG.

Does electroencephalogram have side effect

First, electroencephalogram is harmless to human body. Many people worry that electroencephalogram will have side effects and influence on brain development. In fact, electroencephalogram only amplifies and records the bioelectrical activity of brain cells, and does not give any electrical stimulation. The electrode is attached to the scalp surface and does not cause pain, which is similar to the principle of electrocardiography, Electroencephalogram (EEG) is a kind of curve graph which is amplified and recorded by electroencephalograph

Second: no side effects. EEG and ECG are similar, belong to monitoring, there is no radiation and other things, there is no stimulation or other effect on the human body. EEG has a certain diagnostic value for brain diseases, but it is limited by a variety of conditions, so it can not be used as the only basis for diagnosis in most cases. It needs to be combined with the patient's symptoms, signs, other experimental examination or auxiliary examination to make a comprehensive analysis

Third: EEG is mainly used for the examination of intracranial organic lesions, such as epilepsy, encephalitis, cerebrovascular diseases and intracranial space occupying lesions. EEG is easily interfered by various factors and should be recognized and excluded. EEG is the spontaneous and rhythmic electrical activity of brain cell groups recorded by electrodes. As a kind of recording instrument, it only receives the electric signal produced by human brain and has no stimulating function

matters needing attention

When we do any examination, we'd better consult the doctor first, avoid eating the food that affects the results before the examination, pay attention to exercise, strengthen the body, keep happy, don't give ourselves too much psychological pressure, pay attention to adjust the diet structure, reasonable and balanced diet.
