Relationship between aneurysmal subarachnoid hemorrhage and climatic conditions in the subtropical region, Amami-Oshima, in Japan.
Epidemiological studies of the relationship between climate and the onset of aneurysmal subarachnoid hemorrhage (SAH) have been reported in the temperate and subarctic latitudes. However, the relationship between the incidence of aneurysmal SAH and the climatic variations in the subtropical region remains uncertain. Epidemiological analysis requires study of an extremely isolated area. ⋯ However, the occurrence of aneurysmal SAH tended to be higher in both females and the elderly during the winter and spring seasons and not during other seasons. This study indicates that seasonal and climatic conditions do not strongly contribute to the incidence of aneurysmal SAH in subtropical regions. However, elderly people are affected more by climatic conditions than young people.
