Core Tip

Core Tip: Cognitive impairment in hepatosplenic schistosomiasis goes well beyond minimal hepatic encephalopathy, affecting areas such as visuospatial abilities, working memory, and inhibitory control. Our study, using a brief, culturally adapted assessment battery, found over two-thirds of patients impaired in these domains, often independent of portosystemic shunt presence. These findings call for a paradigm shift from solely minimal hepatic encephalopathy-focused screening to comprehensive, multidimensional cognitive assessment in hepatosplenic schistosomiasis, enabling earlier detection and a more holistic approach to management in endemic, low-resource settings.
