[Semeiotics of incipient forms of vascular diseases of the brain and their diagnosis during preventive examinations of the population].

Using formalized documentation and computerized techniques, the authors analyzed clinical, electrophysiological, and biochemical semiotics in 2180 individuals--healthy subjects, patients with subclinical and initial manifestations of cerebral circulation insufficiency, initial dyscirculatory encephalopathy developing in the presence of neurocirculatory dystonias, atherosclerosis, and arterial hypertension. The author has established characteristics of the semiotics which depend on the nature of the underlying vascular disease, the stage of the process and the patient's age. Tabulated methods and a computerized system of the diagnosis of cerebrovascular disease have been developed. They are based on the employment of a bank of clinical and physiological information used for prophylactic examinations and population screening. The social, medical and economic effectiveness of the proposed methods of the diagnosis and prevention of cerebrovascular diseases allows their recommendation for wide introduction into health care practice.
