Figure 1. Annual trends in the incidence of first-ever stroke from 1992 to 2016 by age and subtypes. tThe increase in stroke incidence was greater in patients aged <65 compared to those aged ≥65 years. In contrast to findings in the elderly population, the incidence of intracerebral hemorrhage (ICH) increased by 9.1% per year for those aged <65 years. Moreover, the increment was significantly higher in women than in men among the patients aged ≥65 years. However, an opposite trend was observed among the younger patients. Over time, the incidence of stroke in the patients aged <65 years continued to increase, while rates of change in the patients aged ≥65 years tended to slow down by degree, both for the total stroke and ischemic stroke (IS).
