Abstract

This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. We hypothesized that cirrhotic patients with minimal hepatic encephalopathy (MHE) have altered cerebral processing of the inhibitory control test (ICT) and N-back test when studied with fMRI compared to healthy individuals. We included patients with non-alcoholic cirrhosis diagnosed with MHE on the basis of a validated psychometric test battery. Age, gender and educational level matched healthy individuals were used as controls and were also given the same psychometric and computerized tests. Analysis of psychometric tests showed that ICT and not N-Back could distinguish between patients with MHE and normal controls even without fMRI scanning. FMRI analysis of the ICT till date has shown that in the lure inhibition state, there are significant differences between controls and MHE patients. FMRI analysis of the N-back task have not been studied till date.
