Abstract

The invention relates to medicine, in particular to diagnostic methods, which can be used in clinical neurology. The aim of the invention is to improve the accuracy of diagnosis of diencephalic syndrome. The proposed method consists in that in a patient in a state of quiet wakefulness, super-slow fluctuations of potential are recorded from the surface of the head in the frequency range of 0.06-0.5 Hz. When rhythmic oscillations appear on the electrogram with a period of 2-4 s and / or 6-8 s, the patient is diagnosed with diencephalic syndrome. The method allows to increase the diagnostic accuracy by 26%.

This invention relates to medicine and may be used in clinical neurology.

The purpose of the invention is to improve the accuracy of diagnosis of diencephalic syndrome.

The method is carried out as follows.

In a patient in a state of calm wakefulness, sitting or lying down with eyes closed, super slow fluctuations of potential are recorded from the surface of the head. The duration of the study is 10-15 minutes. A 20-channel nepei ieHHoro current amplifier — Alvar electroencephalograph with a constant time of 2.5 s (input resistance 4.7 MΩ) is used for recording, which corresponds to a frequency range of 0.06-0.5 Hz, at paper speed 2, 5 mm / s. For registration, use is made of standard dry unpalizable silver electrodes — bridges of the firm Alvar. Electrodes on the surface of the head have an international scheme 10-20. Bipolar method, comSL systems

electrode mutations are standard. Before testing, the stability of the electrodes is required to be checked. The indicator of the stability of the characteristics of the electrodes used was the absence of ultralow fluctuations of the potential of the studied range on pairs of electrodes immersed in a physiological solution and connected to the inputs of the electroencephalograph. When rhythmic waves appear on the electrogram in a patient with a period of 2–4 s and / or 6–8 s, diencephalic syndrome is diagnosed.

Example L- Sick O-va, 32 years old, came with complaints of headache in the right frontal-temporal region, which is very pressing, increases in the second half of the day, at the height of the headache nausea, dizziness, staggering when walking, blurred , increased heart rate and seizures with fever, shortness of breath, palpitations.

Neurologically at admission: there are no focal neurological symptoms, coordinating tests are performed by the respondent “4

Relatively, the sensitivity is not impaired, there are no shell symptoms, the eyelid tremor is noted, the bright distal dermographism, dis. Solid hyperhidrosis, right and left asymmetry of pressure with upper digits up to 120/80, lower 90/60 mm Hg. Art. No pathological changes were detected on the EEG. To register ultralow fluctuations of potentials in the range from 0.06 to 0.5 Hz, the electroencephalograph was switched to another mode of operation: a time constant of 2.5 s and a paper speed of 2.5 mm / s. The electrogram revealed the presence of rhythmic oscillations with a period of 6-8 seconds in all areas (channels). The diagnosis was made: diencephalic syndrome.

The treatment in the clinic was carried out in accordance with the diagnosis. As a result of the treatment, the vegetative manifestations decreased, the number of diencephalic crises decreased, they flowed, and the bioelectric activity was recorded in the range of 0.06-0.5 Hz. On the electrogram, the dominance of oscillations with a period of 2-4 seconds in the occipital and parietal regions of both hemispheres. This made it possible to establish the diagnosis: infectious-allergic cerebral vasculitis with diencephalic crises. Concomitant focal myocardiosclerosis. The treatment was carried out in accordance with the diagnosis.

10 Example 3. Ill. I. B, admitted with a diagnosis of diencephalic syndrome. Complaints at admission: headache caused by his character, more in the temporal and occipital regions, dizziness, feeling

 fear, feeling hot flashes, for no apparent reason, headache intensifies. At the height of the headaches, nausea, sometimes vomiting, followed by relief. He considers himself a patient for about three years. Similar phenomena appeared for no apparent reason.

what is kept slightly unstable go-20 When admitted to the clinic, a professional pain of super-slow activity of the head was performed. Example 2. Sick M-va TS, 32 years old, brain in the range of 0.06-0.5 Hz It was located in the neurological department, electrogram rhythmic fluctuations from which it was transferred from the therapeutic presence. This allowed the diagnosis to be removed; branches. Was admitted with complaints of Ela-diencephalic syndrome. To the patient was a bone, interruptions in the heart, a decline caused by a consultant psychiatrist. 11.01.79 pain-appetite, shortness of breath, feeling of fear, convulsions-on translated into psycho-neurological reduction of fingers. In the therapeutic clinic with a diagnosis of schizophrenia. In the distant ward, she was treated with a diag- ness there.

Nose: myocarditis. When examining the internal-application of the proposed method, it allows to increase the accuracy of diagnosis of the diencephalic syndrome by 26%.

No data about current myocarditis was found. Astenisation is expressed in the neurological status, the smoothness of the right nasolabial fold is light, and deep reflexes are revived with a non-permanent dominance to the right. Disorders of sensitivity do not present. The coordinator with droma by registering a bioelectric sample performs satisfactorily. EEG data indicate diffuse changes in brain biopotentials and the presence of a nidus of pathological activity in the right temporo-occipital region.

0 Upon admission to the clinic, a registration of the super-slow activity of the golub brain in the range of 0.06-0.5 Hz was performed. On the electrogram there are no rhythmic oscillations. This allowed the diagnosis to be removed; diencephalic syndrome. A consultant psychiatrist was called to the patient. 11.01.79 the patient was transferred to a psycho-neurological dispensary with a diagnosis of schizophrenia. In the future, treated there.
