[The prediction of the development of circulatory encephalopathy in hypertension patients with the initial manifestations of brain blood supply insufficiency].

The principal risk factors conducive to the development of cardiovascular diseases in young and middle-aged subjects with chronic cerebrovascular insufficiency due to Stage I or II essential hypertension were under study. Thirty-four male patients with the initial manifestations of inadequate blood supply to the brain (IMIBS), 35 male patients with stages I or II dyscirculatory encephalopathy (DE), and 32 and 33 female patients with the same conditions, respectively, were examined. Hypertensive cerebral crises were significantly more frequent in DE patients of both sexes than in IMIBS patients, and a tendency to a longer standing of arterial hypertension was observed in DE patients as against those with IMIBS.

[Variants of the clinical course of circulatory encephalopathy and the significance of certain risk factors].

Based on the results of a many-year dynamic follow-up of 151 patients with dyscirculatory encephalopathy (DE), the authors distinguish six variants of its clinical course: stable, slowly progressing without paroxysms or transient disorders of brain circulation (TDBC), slowly progressing with paroxysms, that with TDBC, intermittent, rapidly progressing. The two former variants are referred to the favorable type of DE course, the rest are considered unfavorable. The major risk factors in the patients with the favorable and unfavorable patterns of DE were studied, as well as the contribution of these factors to the development of DE.

[Study of prevalence and structure of cerebrovascular disorders in different regions of the USSR based on simultaneous epidemiological examinations].

The authors describe the data of the screenings of the representative random samples from the open male population aged 20 to 54 years, carried out in accordance with the common program in 6 cities of this country. The prevalence of definite cases of cerebrovascular diseases (CVD) ranged from 7.7% in Moscow to 12% in Irkutsk.
