What about electroencephalogram

summary

Some time ago, I was a little busy at work, so I had little time to rest. I always felt dizzy and had no time to go to see the doctor. I didn't go to the hospital until I was free a few days ago. The doctor gave me an EEG. Today, let me talk about how to see the EEG.

What about electroencephalogram

First, brain tissue itself can spontaneously generate bioelectrical activities. Electroencephalogram (EEG) is the result of the electric activity of brain cells and electrodes on the scalp, which is amplified and 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.

Second, the electroencephalogram recorded by the current electroencephalograph 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.

Third: EEG is the spontaneous and rhythmic electrical activity of brain cell population recorded by electrodes. EEG is the most important examination tool in the diagnosis and treatment of epilepsy. Theta wave often appears in drowsiness, delta wave often appears in sleep, and it can also appear in extreme fatigue or 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.

matters needing attention

Therefore, when we encounter problems, we should seek the help of professional doctors in time, pay attention to rest at ordinary times, avoid excessive use of brain, combine work with rest, pay attention to timely physical exercise, enhance physique, maintain healthy and good living habits and diet structure, and pay attention to smoking and drinking.
