[State of cerebral hemodynamics in healthy subjects and diagnosis of the subclinical manifestations of inadequate cerebral blood supply].

Results of clinical and physiological examinations of 389 practically healthy subjects and 96 persons with subclinical manifestations of insufficient blood supply of the brain are presented. The healthy probands showed an intensification of autonomodystonic manifestations with age, while in the persons with the subclinical manifestations of the insufficient blood supply no dependence of the symptoms on age was revealed. REG findings showed that in the healthy subjects the pulse blood flow diminished, the vascular wall tone increased, and the vascular wall elasticity decreased with age. In distinction from this the above symptoms appeared in the persons with the subclinical insufficiency as early as on the 3d decade of the life. The persons with these symptoms constitute a high-risk group and need prophylactic measures.
