[Correlation of some instrumental, metabolic and clinical parameters in cerebral atherosclerosis].

The epidemiological, clinical and instrumental features of cerebral circulatory insufficiency are examined in an assessment of the criteria required for correct diagnosis. The need to refer to both direct and indirect criteria is illustrated in the light of a series of cases. From the 4th decade of life onwards, males are more prone to cerebral arteriosclerosis. Hypertension, diabetes and obesity are significant risk factors. The findings obtained by various methods of examination are critically discussed. Their correct interpretation naturally demands correlation with the clinical data.
