We investigated the cortical thickness and volume across a group of Hepatitis C patients before and after interferon (IFN) therapy employing an automated method for regional parcellation. Significant increase of cortical thickness was observed in lateral occipital in both hemisphere in patients after IFN. Increase cortical volume were seen in both hemisphere at the caudal middle frontal, rostral middle frontal superior temporal and also in left precentral, left lateral orbitofrontal, right middle temporal after IFN. The areas that showed significant reduced cortical volume were left medial orbitofrontal, right fusiform and bilateral lateral occipital.
