[Diagnosis of a cerebral infarct with a hemorrhagic component].

Using computerized methods the authors have analyzed formalized case histories of three variants of an acute disorder of the cerebral circulation in the matter of the cerebral hemispheres verified by pathoanatomical studies: (1) cerebral infarction with a hemorrhagic component (n = 88), (2) a gray ischemic cerebral stroke (n = 80), (3) parenchymatous hemorrhage (n = 71). The informative symptoms and symptom complexes identified can be employed for the differentiation between cerebral infarction with a hemorrhagic component and other types of strokes.

[Statistical patterns in the distribution of spontaneous subarachnoid hemorrhages].

A study of 788 cases of spontaneous subarachnoidal hemorrhages, which were observed in some neurological clinics during the past 5 years, permitted an analysis of the statistical data concerning the distribution and outcomes of this form of strokes depending upon the age of the patient and etiology. Among the observed population, individuals of a young and middle age prevailed (78% of the patients were younger than 60 years). The role of separate etiological factors is different in different age groups in individuals under 40, subarachnoidal hemorrhages are mainly produced by a rupture of cerebral vascular aneurysms; in the age group of 40--59 years by arterial hypertension, while in the elderly by atherosclerosis in combination with arterial hypertension.
