summary

Recently, I felt uncomfortable, so I went to the hospital with my family to have a comprehensive examination. The EEG results came out, but I couldn't understand them. So I consulted a professional doctor about how to see the EEG. Now let me tell you how to see the EEG results.

How does electroencephalogram see a result

First, theta wave often appears in drowsiness, delta wave often appears in sleep, when extremely tired or under anesthesia. In some normal people, a small amount of theta wave can be seen in the front of the hemisphere, and there is almost no delta wave when awake. Sharp and slow waves generally indicate epilepsy. Sharp waves often appear in brain hypoxia, and brain tissue itself can spontaneously generate bioelectrical activity.

Second: electroencephalogram (EEG) is the result of the electrical activity of brain cells and electrodes on the scalp. After amplification, it is recorded on paper to form a certain graphic curve. It reflects the functional state of the brain at any time. Under normal circumstances, these bioelectrical activities are very small (one millionth of a volt) and cannot be recorded by ordinary instruments.

Third: the wave recorded by the current EEG machine is the result of a million times amplification. When the brain lesions, EEG will have the corresponding abnormal changes. Especially in the case of epilepsy, EEG will appear epileptic discharge, this kind of discharge not only in the seizure, but also in the intermission period, which is of great significance for the diagnosis, positioning, qualitative and curative effect observation of epilepsy.

matters needing attention

When we go to the hospital for examination, the examination results of large and small are not what we ordinary people can understand, especially the examination results of some images. Therefore, it is better for patients to seek the help of doctors. Under the guidance of doctors, they can understand their own physical conditions and effectively treat diseases.
