Impact of preexisting cognitive impairment and race/ethnicity on functional outcomes following intracerebral hemorrhage
Stroke Jan 23, 2021
Sawyer RP, Yim E, Coleman E, et al. - In a multiethnic population, researchers analyzed the role of preexisting cognitive impairment on short-term mortality and functional outcomes after intracerebral hemorrhage (ICH). Patients with ICH were prospectively registered as cases for the GERFHS III (Genetic and Environmental Risk Factors for Hemorrhagic Stroke) Study and the Ethnic/Racial Variations of ICH Study. Of the 3,537 ICH cases, 304 patients had cognitive impairment before ICH. In the White, Black, and Hispanic subgroups, preexisting cognitive impairment was correlated with loss of independence 3 months after ICH, when matching for risk factors of cognitive impairment. This indicates that, regardless of race/ethnicity, preexisting cognitive impairment has a detrimental impact on obtaining functional independence after ICH.
