We explored national and regional characteristics based on age, gender, and prognosis of subarachnoid hemorrhage by using the Japanese Stroke Data Bank, a data bank of acute stroke patients established to provide evidence for standardization of Japanese stroke management. We analyzed data from 1,183 patients with subarachnoid hemorrhage in the Japanese Stroke Data Bank. For regional investigation, we divided the patients into 3 groups according to their place of residence: Hokkaido, Tohoku, and the area west of Kanto. The total male-to-female ratio was 1:1.88. The female proportion was dominant in older patients: 1:2.27 in the 60s, 1:4.48 in the 70s, and 1:4.63 in the 80s. The age distribution of the patients was apparently different between male and female. Female patients (mean age: 64.5) were older than male patients (mean age: 56.1)(p In total, favorable outcome (mRS of 0-2), extremely poor outcome (mRS of 5-6), and death (mRS of 6) were 58.0%, 28.3%, and 19.8%, respectively. In a regional analysis, the outcome of the patients of the area west of Kanto was poorer than that of Hokkaido and Tohoku (p
