Express it at one time!Regarding EEG examination, what you want to know is here

1. What is EEG?

EEG check is to put the electrode made of metal on the scalp. The electrode is connected to the wires. Through the processing of precision instruments, the brain waves are finally turned into waveforms that can be seen by the doctor on the computer.

It is the spontaneous biological electricity of the brain. It is the spontaneous and rhythmic electrical activity of the brain cell group recorded by the electrode. It is not DC and the AC electricity, but biologics. This recording of the undulating curve waveform is the EEG we said.

2. Is there any radiation of EEG?

During an electro -electrocardiogram, the brain did not accept any stimulus, just to record its own electrical activity, so this is a painless, non -invasive brain function test, and does not apply any external interference to the brain.

Therefore, unless the disease occurs during the examination, the EEG examination itself does not cause any abnormal sensation and discomfort. It is not only safe for adults, but also safe for children. influences.

3. Under what circumstances do I need to do an electrocardiogram?

B. Central nervous system infection.

C. Cranial occupying lesions.

D. Cranial damage.

E. Intelligent obstacles, conscious disorders, pediatric twitching, polymophilic, alcoholism, hypoxia and ischemic encephalopathy, etc.

F. Genetic metabolic disease.

g. Brain functional disorders caused by other reasons.

H, brain death monitoring.

4. What are the preparations for EEG?

A. Wash your hair the day before the inspection, and you cannot use oil to reduce the skin resistance caused by the scalp oil.

B. Examination should be performed within 3 hours after eating to avoid the results of the inspection results of hypoglycemia caused by hunger.

C. Relax the whole body during inspection to avoid interference caused by excessive tension.

D. Patients with epilepsy are taking antiepileptic drugs. Except for special diagnosis, the drug should not be discontinued.

5. What are the taboos of EEG?

A. Severe scalp trauma, extensive or open craniocerebral trauma, cannot place electrodes or may cause infection due to examination.

B. Extreme manic and disturbing cannot cooperate with the inspectors.
