Obsessive compulsive disorder (OCD) is an anxiety disorder characterized by intrusive, distressing thoughts and ritualistic, repetitive behaviors. Despite many theory-driven neuroimaging studies, few studies have examined alteration of the whole network in OCD. In this study, we examined the cortico-cortical connectivity using cortical thickness and characterized abnormal network efficiency in OCD.
We found significant group differences in the global efficiency but not in the local efficiency. Additionally, we found significant group differences in neighboring efficiency in the ROIs that are not restricted to the “orbitofronto-striatal” circuits.
Further studies may reveal an alteration of the OCD brain network that has been unattended.
