Abstract

Background and Purpose: Intracerebral hemorrhage (ICH) has the highest mortality rate among all strokes. While ICH location, lobar versus non-lobar, has been established as a predictor of mortality, less is known regarding the relationship between more specific ICH locations and functional outcome. This review summarizes current work studying how ICH location affects outcome, with an emphasis on how studies designate regions of interest. Methods: A systematic search of the OVID database for relevant studies was conducted during August 2015. Studies containing an analysis of functional outcome by ICH location or laterality were included. As permitted, the effect size of individual studies was standardized within a meta-analysis. Results: Thirty-seven studies met the inclusion criteria, the majority of which followed outcome at 3 months. Most studies found better outcomes on the Modified Rankin Scale (mRS) or Glasgow Outcome Score (GOS) with lobar compared to deep ICHs. While most aggregated deep structures for analysis, some studies found poorer outcomes for thalamic ICH in particular. Over half of the studies did not have specific methodological considerations for location designations, including blinding or validation. Conclusions: Multiple studies have examined motor-centric outcomes, with few studies examining quality of life (QoL) or cognition. Better functional outcomes have been suggested for lobar versus non-lobar ICH; few studies attempted finer topographic comparisons. This study highlights the need for improved reporting in ICH outcomes research, including a detailed description of hemorrhage location, reporting of the full range of functional outcome scales, and inclusion of cognitive and QoL outcomes.
