Approximately 10% of the 795 000 strokes per year in the United States are intracerebral hemorrhages (ICHs),defined by brain injury attributable to acute blood extrav-asation into the brain parenchyma from a ruptured cere-bral blood vessel. The clinical impact of ICH appears disproportionately high among lower-resource popu-lations both in the United States and internationally. In US-based studies, ICH incidence has been reported to be ≈1.6-fold greater among Black than White people and 1.6-fold greater among Mexican American than non-Hispanic White people. Internationally, ICH incidence is substantially higher in low- and middle-income versus high-income countries, both as a proportion of all strokes and in absolute incidence rate.
