Encephalogram of the brain: where it can be done and how much it costs

Where can an encephalogram of the brain be done

Electroencephalography (from the Greek enkephalo - brain and graphein - to write) is a method of studying brain activity. EEG measures and records the bioelectrical activity of the brain. The EEG of a normal healthy adult in a state of relative rest is characterized by two main rhythms: an α-rhythm with an oscillation frequency of 8-13 Hz and an amplitude of 25-55 μV, a β-rhythm with indicators of 14-30 Hz and 15-20 μV, respectively. Various pathologies change the picture of the encephalogram.

EEG is used to assess brain disorders:

1. Diagnostics of epilepsy, control, selection of therapy and determination of seizure type.
2. Clarification of the cause of sudden loss of consciousness.
3. Determining the type of dementia.
4. Elucidation of the causes of sleep disorders.
5. Monitoring of brain activity during operations under general anesthesia.
6. Diagnostics of tumors.
7. Definition of brain death.

What does the EEG of the brain show in children? Thanks to the procedure, it is possible to study functional disorders in neurology (neurotic, emotional, behavioral and cognitive disorders, psychosomatic diseases).

How research is done

A standard EEG takes about one hour. The patient is usually placed on a couch or in a comfortable chair. To measure electrical activity in various parts of the brain, a medical professional fixes up to 20 electrodes on the patient's scalp or puts on a special cap with attached sensors. A computer records the electrical activity of the brain on a screen and on paper as a series of wavy lines.

EEG video monitoring helps the doctor see what happens immediately before, during and after an epileptic attack, and to discover which specific area of ​​the brain is responsible for the disturbance. This type of research is necessary for the diagnosis of psychogenic seizures, which can look like real seizures, but at the same time do not affect the electrical activity of the brain. Video monitoring is short-term and long-term. The first is possible in outpatient settings and lasts up to six hours. The patient moves freely with sensors attached to the head, which allows for long-term recording of brain activity. Long-term monitoring is carried out in hospital conditions, the study takes 3-7 days.

Electroencephalography during a child's sleep (often called EEG of a child's sleep) is the most indicative diagnostic method of studying the functional activity of the brain. It allows to differentiate between epileptic and non-epileptic causes of the disease. EEG is performed for children under one year of age only while they are asleep. So that the baby is guaranteed to fall asleep, it is advisable to take into account his usual sleep schedule when setting the time of the procedure.

How much does an EEG cost

Research is conducted in accordance with the standard protocol for conducting special tests. Usually, EEG is performed using stroboscopic simulation (flashes of bright light on the eyes) and hyperventilation (deep breathing).

The cost depends on the type of electroencephalogram. The price of overnight EEG monitoring is higher than the price of a standard examination. During a specialized EEG, the patient is placed in a room, the environment of which stimulates relaxation, electrodes are connected and asked to fall asleep. The cost of an encephalogram of the brain of a child older than two years is identical to the cost of an EEG for an adult. EEG for newborns and children under two years of age will cost less.

Deciphering the results of the study: rhythmic bioelectric activity with bursts of paroxysmal activity indicates the presence of an area in which the processes of excitation exceed the processes of inhibition. Such an EEG may indicate the presence of a migraine in the patient.

Diffuse EEG changes in the bioelectric activity of the brain in the absence of other disorders can be considered a variant of the norm. That is, if the conclusion records only the presence of diffuse or moderate changes in the bioelectric activity of the brain without detected paroxysms or foci of pathological activity, then the diagnosis of epilepsy is not confirmed.

Where can an encephalogram of the brain be done? In a hospital, private clinic or any other medical institution where there is an electroencephalograph and where brain research is carried out.
