What is electroencephalogram? What should we pay attention to doing EEG?

EEG is not unfamiliar to everyone, many people are consulting about doing EEG things, but we do not know what is called EEG, do EEG need to pay attention to what? Today I will introduce to you about EEG knowledge.

What is electroencephalogram?

Human tissue cells are constantly producing weak electrical activities. The electrodes placed on the scalp are used to induce the electrical activity of the brain cells and magnify the electroencephalogram. The electroencephalogram (EEG) is recorded on a special paper. When the pathological or functional changes occur in the brain tissue, the curve changes accordingly, which provides the basis for clinical diagnosis and treatment. So far, EEG is one of the most important, valuable and convenient methods in the auxiliary diagnosis of epilepsy.

Clinical application of electroencephalogram

1. epilepsy

Because EEG can accurately record scattered slow wave, spike wave or irregular spike wave when epilepsy occurs, EEG examination is very accurate for the diagnosis of epilepsy, and EEG can guide the withdrawal of antiepileptic drugs.

2. mental illness

In order to diagnose schizophrenia, manic depression, mental disorders and so on, can do electroencephalogram examination, excluding other brain diseases including epilepsy.

3. other diseases

The electroencephalogram (EEG) depicts not only the localized or diffuse pathological manifestations of brain diseases such as epilepsy, tumor, trauma and degenerative diseases, but also the changes of central nervous system caused by extracerebral diseases such as metabolic and endocrine disorders and poisoning.

Electroencephalogram (EEG) examination is an effective method to check the changes of brain function. Because the changes of brain function are dynamic and changeable, some patients with clinical manifestations of brain dysfunction can not completely rule out the existence of brain diseases when they do not find abnormalities in EEG examination, but should be carried out regularly. EEG reexamination can accurately detect disease.

What should we pay attention to doing EEG?

We have heard about EEG, but what should we pay attention to when we do EEG?

Wash your head clean and do not smear oily matter.

Electroencephalogram room should be quiet and comfortable.

(3) sleep well the night before (except those deprived of sleep).Meilun

(4) The operator should be kind and friendly, and will ask the patient to explain clearly, so that the patient can fully understand and cooperate, and strictly follow the operator's instructions.

_Ampere discharge plate should be gentle and accurate, so that it is placed close to the skin, medical education network | collection and finishing this is the key to do a good job of EEG.

For those who are too young or unable to cooperate, oral chloral hydrate or enema should be given if necessary.Meilun

For patients with febrile convulsions, it is best to check EEG after 10 days of symptoms.
