When appoint REG of a head and what is this procedure

1 Reoencephalography of the brain

Reoencephalography of the brain allows to measure the value of pulse blood filling, to learn how elastic the walls of blood vessels, to check their reactivity.

Peripheral resistance and overall vascular tone are also determined by this method. You can find out at what speed the pulse wave is distributed, what is the rate of blood flow.

Most of these parameters are clear only to specialists, but as a whole they allow to estimate the functioning of the cerebral circulation system at different angles.

It allows you to compare the state of the vessels of the right and left hemispheres, to identify abnormalities that are characteristic of the pre-sinus condition, atherosclerosis, dystonia and many other diseases.

Information on the blood flow REG is obtained differentially in the brain and in the level of blood vessels( from the capillaries to the largest veins and arteries).

2 Features of the

procedure The first time the head REG was held in 1959.Spent her FL.Jenker. He is the author of the present term. But they allowed him to carry out this study of the work done before by Soviet scientists( Naumenko and Kedrov) and their Western counterparts( H. Yarulin, K. Polzer, F. Shufrid).

Scientists have established the fact that blood that moves through the vessels has less electrical resistance than other tissues. Venous and arterial blood also differ in their resistance.

When carrying out REG, a high-frequency current with a low voltage is passed through the head tissue. The sensors measure the change in resistance at this time. The obtained curves are deciphered, compared with the standards and conclude that there are deviations in the patient's blood flow.

3 Rheograph

For the patient, the procedure for the passage of the rheoencephalogram is not burdensome. For 24 hours before the procedure, you must stop taking any medications that affect blood circulation. You should not smoke for at least 2 hours before the start of recording.

The patient is put in and asked to take a pose in which he feels comfortable. Then, a swab with alcohol rubs the places for fixing the electrodes( round metal plates 2-4 cm in size).Electrodes are lubricated with a special conductive paste and fixed on the head with rubber straps. One of the electrodes can be placed on the mastoid process.

After that, the fixing device( rheograph) is turned on and the recording of readings starts. A rheograph can have a different number of channels( from 2 to 6).More channels allow simultaneous recording on several parts of the brain.

During the procedure, the patient may be asked to make any movements, take a few deep breaths( hyperventilation).This allows you to compare the readings in a state of rest and activity. The result of REG in the state of rest is called the background. Also, to increase the informative value, the procedure can be performed after taking medications to constrict or dilate the vessels.

The procedure takes no more than half an hour. A doctor may need a little more time to describe the results.

Because of the similarity of the procedure and the name of the REG, it is often confused with EEG( electroencephalography), which fixes electrical impulses emitted by the brain regions. It is necessary to know that these are two completely different studies. And their appointments are different.

4 Survey results

At the output of the rheograph work, circular curves are obtained. One cycle of the curve displays the readings recorded for one heartbeat, as well as on an electrocardiogram more familiar to the average person. Often the results of these two surveys are considered simultaneously for a more accurate interpretation of the results obtained.

Each curve tooth has a slope, amplitude, can accurately repeat the others or have malfunctions.

In young healthy people, the angle of inclination of the curve is much higher, the teeth are more pronounced than in the elderly. And with vegetovascular dystonia, the REG and right hemisphere curves may differ significantly.

With atherosclerosis, the height of the waves decreases, additional waves can appear from time to time.

For these and other characteristics, the doctor determines the likely disease and degree and its development.

The following types of deviation in REG are distinguished:

• angiodystonic( characterized by difficulty in blood circulation with decreased vascular elasticity and decreased vascular tone);
• hypertensive( characterized by difficulty in the flow of blood from the brain through the veins and associated high blood pressure);
• diastolic( there is variability of the vascular tone, at the same time a low filling of the vessels and a difficult outflow).

5 Indications for use

First of all, the method is used to determine the damage of cerebral vessels. The rheoencephalogram will be useful in diagnosing such diseases:

• brain concussion;
• ischemia of the brain;
• stroke and pre-stroke condition;
• vegetovascular dystonia;
• pituitary adenoma;
• atherosclerosis of cerebral vessels;
• bruising;
• vertebrobasilar insufficiency.

The reason for the passage is any mechanical trauma to the head, as well as complaints about the following ailments:

• frequent headaches;
• dizziness;
• tinnitus;
• loss of orientation with a sharp change in body position;
• deterioration or loss of memory;
• reduced intellectual performance;
• meteosensitivity;
• syncope;
• vision impairment.

REG can still be used to supplement the picture obtained during the MRI of the brain.

Most often, REG registers when symptoms of the disease have already manifested itself. Elderly, it is advisable to conduct REG for preventive purposes. The interpretation of the results obtained can be of invaluable help in the treatment of diseases of the vascular system at an early stage. So you can not only avoid a stroke, but also ensure the quality of the brain for a longer period due to timely therapy.

6 Contraindications

There are no contraindications for conducting REG.It can be done for children and pregnant women. It is not invasive - it does not cause damage or pain. Can be held any number of times. Modern conductive pastes do not cause allergies.

The study is usually done while sitting, but if necessary, you can record the lying patient.

Refuse this survey for other reasons. The first is the habit of modern man not to pay attention to his condition. So, people can suffer from migraines for several years, drowning out her anesthetic painkillers.

And after all it is possible to pass or take place inspection and to appoint or nominate therapy which, probably, will rescue or save from serious disease of a brain.

The second reason is neglect of REG, as an outdated method of examination. After all, there is an MRI, CT, ultrasound and dopplerography. Yes, today they exist. These are wonderful techniques that greatly facilitated modern diagnosis.

But REG is the simplest and most affordable method for detecting at an early stage the danger of very many diseases.

It is inexpensive, takes a little time and is completely harmless to humans. And with all the advantages of more modern techniques, REG will still not be superfluous, since it will supplement their indications and expand information on the blood supply to the patient's brain.
