Chronic hepatitis C virus (HCV) infection is a growing global health problem. HCV is a leading cause of chronic hepatitis, cirrhosis, and hepatocellular carcinoma (HCC) and is associated with more than 30 extrahepatic manifestations (EHMs). Although cryoglobulinemia is the main pathological cause of neurologic EHMs, HCV viral replication in the brain itself must also be taken into consideration. The most signiicant neurological manifestations of HCV chronic infection are stroke, leukoencephalopathy, encephalomyelitis/myelitis, and peripheral neuropathy. The most signiicant neuropsychological manifestations of HCV infection are fatigue, depression, anxiety, and cognitive dysfunction. Antiviral HCV treatment should be the irst-line treatment for managing mild-tomoderate vascular and neurologic symptoms; most of EHMs improve or even resolve if antiviral treatment starts on time.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
