Dementia can be defined as a syndrome of global and progressive impairment of acquired cognitive abilities. Importance of early detection of HCV infection in prevention of cognition decline in infected patients is emphasized along with the fast progressive form of dementia caused by HCV trough possible patogenetic mechanismas presented in this paper.展开更多
