Using a neurological, psychiatric, experimental neuropsychological and REG study with the use of functional tests, the authors studied 66 patients with different stages of dyscirculatory encephalopathy and 20 normals of the same age (a control group). These patients demonstrated different degrees of disturbed intellectual and mnestic activities, a drop of attention and general activity, the speed of reactions, as well as different forms of expressed psychoorganic symptoms developing on the background of diffuse and eventually of microfocal neurological symptomatology. The REG data revealed relation between the stage of the disease on the one hand and the state of the vascular tone, elasticity of the vascular wall, level of arterial pessure and pulse blood repletion, the state of the venous outflow on the other. Changes of such parameters indicate to a prevalently functional character of these changes in the I stage and partly in the II stages of dyscirculatory encephalopathy and mainly organic in its III stage.

Cavinton was used for 10 years in 967 patients with different cerebrovascular diseases. The highest effect was seen in patients with early forms and primarily chronic forms: vegetovascular (neurocirculatory) dystonia, initial manifestations of brain blood supply insufficiency, circulatory encephalopathy in the first and second stages. Improvement of the subjective status and a decrease of the intensity of vestibulocerebellar disorders were recorded by the end of the treatment in 75-85% of such patients. In ischemic brain stroke, regress of general cerebral and focal symptoms was more rapid and significant in the adequate reaction type of cerebral hemodynamics to cavinton administration (a rise of pulse blood content of the brain and a reduction of the vascular tone according to the REG data) and was less noticeable in the hypertonic and, in particular, in the hypotonic type. Cavinton should not be used in severe general cerebral hypertensive crises, as well as in elderly or senile patients with acute cardio-cerebral or cerebro-cardiac syndrome, postinfarction cardiosclerosis, marked disorders of heart rhythm.

Overall 106 patients with atherosclerotic cccccccirculatory encephalopathy (DE) were examined for changes in the EEG, REG and in certain psychological parameters (attention, memory, "associative" thinking) before and after acupuncture and carbon dioxide baths. In patients with stage I and stage II DE (in 93 and 80%, respectively), the clinical improvement was accompanied by positive changes such as a rise of alpha-activity, decrease of pathological waves and frequencies on the EEG, decline of the vascular tone and improvement of the blood content on the REG in addition to the shortening of the time required for the search for numbers according to Schulte's tables, a decrease of errors made during calculation, an increase of words and the family of words in the memorization and "associative" thinking tests. The data obtained may attest to the amelioration of cerebral function and hemodynamics because of the rehabilitation treatment.

According to the authors' observations, the symptoms of nervous system derangement associated with legionnaires' disease rather often enter the disease structure and can virtually be characterized as a manifestation of infectious and toxic encephalopathy and polyneuropathy (encephalopolyneuropathy). In the majority of cases, the neurological disorders develop acutely or subacutely after or simultaneously with respiratory lesions. The clinical picture of encephalopathy is marked by permanent headache, mental abnormalities, memory disturbances, insomnia, pronounced astheno-vegetative and vascular manifestations. In patients with legionellosis, polyneuropathy is manifested by paresthesias, less frequently by pains in the distal parts of the limbs and myasthenia without visible atrophies. Vegetative disorders such as vegetative polyneuropathy of the hands and legs, visceral polyneuropathies are typical symptoms of the disease whatever its gravity. Vegetovascular dystonia together with long-term AP instability is an obligate sign of the disease. Electrophysiological examinations (EEG, REG, EMG) support the clinical findings and may serve the basis for an objective evaluation of the gravity of the neurological disorders. The degree of pulmonary lesions and the intensity of vegetative disorders eventually determine the torpidity and characteristics of the disease course.

A comprehensive examination involving the use of electroencephalography (EEG), rheoencephalography of the main vessels of the head (REG) and vessels of the limbs, electromyography with the application of neurohistological investigation was conducted in 120 myeloma patients. Neurological disorders systematized into syndromes of encephalopathy, local spondylalgia, radiculalgia, myelopathy, meningomyelopolyradicular and encephalomyelopolyradiculoneuropathic syndromes were observed in 91.7% of the cases. The leading role in the pathogenesis of neurological disturbances was played by toxico-dyscirculatory disorders secondary to infiltration of vessel walls by plasmatic cells, dysproteinosis, kidney failure, as well as mechanical impact of the deformed vertebral column on the spinal cord, its radices and vessels. Modern medicated correction of neurological disturbances is considered necessary in myeloma.

Using noninvasive (echoventriculometry (Echo-VM), REG and invasive (planimetric PEG, graphic recording of the CSF pressure) methods of examination, the authors determined the size of cerebral ventricles and the status of the cerebral hemo- and CSF dynamics in 606 patients with various chronic diseases of the brain (consequences of craniocerebral injury, epilepsy, discirculatory encephalopathy, etc.). According to PEG and Echo-VM findings, two groups of patients were distinguished. In moderate dilatation of cerebral ventricles the most significant finding was an increase in the pulse pressure of the CSF, whereas its mean pressure was normal or slightly elevated. In patients with pronounced hydrocephaly the pulse and mean pressure of the CSF tended to decrease. The progress of hydrocephaly was parallelled by increasing disorders of the cerebral hemodynamics expressed in hindered venous outflow from the cranial cavity and elevated peripheral vascular resistance. Four CSF-related syndromes have been identified (normotension, total CSF hypertension, intraventricular tension, total CSF hypotension) differing in their diagnostic and prognostic significance and in the pathogenesis of disorders of the hemo- and CSF dynamics.

A total of 171 patients of young, middle, and old age presenting initial manifestations of cerebral circulatory insufficiency and early disordered-circulatory encephalopathy were treated with cavinton. The clinical effect of the drug mostly expressed in a considerable decrease of subjective manifestations of the disease was fairly high in most patients of different age groups. The most pronounced positive shifts (according to REG) of the cerebral hemodynamics upon cavinton therapy were observed in young and middle-aged patients. A lower efficacy in elderly patients was explained by the fact that there were grave organic changes in the cerebral vessels, predominantly in those of small and medium caliber. A comprehensive nature of the drug action, as well as the absence of any adverse effect on the cerebral hemodynamics recommend cavinton as a drug of choice in the treatment of patients with chronic forms of cerebral ischemia, including elderly ones. The drug should not be administered to patients over 60 years of age with marked disorders of cardiac activity.

Orthostatic test with passive tilting of the upper body was performed in 28 patients with VVI pacemaker. The changes in BP (Riva-Rocci method), CVR and CBF (impedance technique, REG II) as well as in EEG (automatic spectral analysis) observed after tilting, were compared to those in 20 age-matched controls. While in healthy subjects the autoregulation of the CBF was accomplished through a decrease in CVR and resulted in a moderate but significant increase in CBF, in patients the CVR did not change. This event was estimated as a sign of impaired autoregulation, the CBF remained unchanged most probably on account of the increased diastolic and mean BP. Alpha and beta power spectra in the EEG rose significantly after tilting, the shifts being more pronounced in the controls. In the patients there was an increase in theta activity. Cerebral angiopathy due to "subclinical" brain ischaemia during cardiac rhythm disorders preceding pacemaker implantation was accepted as a mechanism underlying the disturbed autoregulation of the cerebral blood flow. For the occurrence of alterations in orthostatic EEG reactivity, a dyscirculatory encephalopathy has been suspected.

The authors investigated the diagnosis and treatment of the initial forms of venous encephalopathy in atherosclerosis in 42 patients, using synchronous rheoencephalography and jugular rheophlebography under conditions of graded exercise on a bicycle ergometer. The study revealed signs of venous encephalopathy with dystonic, asthenovegetative, psychopathological, pseudotumorous and other syndromes which were confirmed by changes in the parameters of the REG, rheophlebogram, etc. Graded exercise in a compensated phase of the disease led to a reduction in signs of venous congestion in the brain, while in a subcompensated phase these signs increased. The effect of a multiple modality treatment with due regard to the phase of compensation and the leading syndrome was good or satisfactory in the majority of patients.

Clinical and polygraphical (EEG, EOG, EMG, ECG, REG) studies of nocturnal sleep and of the hemodynamics were carried out in 60 patients with dyscirculatory encephalopathy induced by hypertension and atherosclerosis. The findings obtained demonstrate that the clinical picture in these patients is always characterized by sleep disturbances which decrease the level of their diurnal wakefulness and their capacity for work. Hemodynamic disturbances responsible for sleep disorders are in turn maintained by the latter which leads to the formation of the vicious circle. This is also supported by the fact that compromized cerebral circulation causes changes in the activity of the structures involved both in sleep-wakefulness function and the regulation of the cerebral and systemic hemodynamics. Hence, deviations in the nocturnal sleep pattern attended with pronounced alterations in the cerebral hemodynamics may contribute to the development of acute disorders of the cerebral circulation. The authors recommend correcting not only the disrupted structure of sleep but also the cerebral circulation with relation to he sleep-wakefulness cycle.
