Encephalography is also often referred to as the electroencephalogram or EEG for short. This procedure is absolutely painless and is performed.

How is the procedure of EEG

At carrying out EEG the patient puts on his special helmet. Therein the electrodes, so it looks quite original and interesting. These wires are connected with the basic device – electroencephalograph, which receives all the data.

During the execution of the procedure, the patient should sit in a chair in a comfortable position. Eyes, usually he at this time covered.
The main difficulty with the use of this procedure in children is to persuade the child to sit quietly and just a few minutes. Because the helmet can easily scare the baby.

The reliability of the results is ensured by isolation of the patient from light and sound. Before the procedure you need to eat because hunger can have an impact on the human brain, with the result that the data is unreliable.

First, doctors are studying alpha rhythms of the brain, and then move to check its reaction to external stimuli. Stimulation is usually performed using light and twocolumn. All this effects have to be calculated and measured. For example, if the light is used, the flash can not be more intensively 0.6 j.
If the procedure is performed the patient is unconscious, the main stimulus may be a pain. The doctor may push the fingernail skin or use other options.

The meaning of this check is to calculate the length of the oscillations and return the brain to its normal working rhythm. Based on these parameters, it is possible to compile a full picture of the brain.

However, today increasingly used to study brain activity, not EEG, and modern methods, like CT and MRI.

When EEG is indispensable

Despite the fact that today the EEG is already so popular as it was 15 years ago, it still remains the best method of research in epilepsy. It is the encephalogram of the brain allows us to separate non-epileptic seizures brain activity of an epileptic. In addition, it helps to identify foci of epileptic activity, which is very important and useful for their treatment and correction.

One of the advantages of this method of research usually distinguish its low cost and complete safety to the patient. In addition, it is easy to hold the man in a coma. After all, the EEG accurately reflected the adequacy of work of all structures of the human brain.
