A prospective epidemiological study of cerebrovascular diseases and transient ischemic attacks (TIA) is presented. During a three-year period the annual incidence of strokes was 2.90 and of TIA 0.45 per thousand population. This difference in incidence and the disparities in age characteristics favour the hypothesis that TIA precedes only a minority of the strokes. The short-term mortality is high among the stroke patients.
