Common and differential alterations of general emotion processing in obsessive-compulsive and social anxiety disorder

Abstract

Overall, we could identify common fronto-subcortical hyper-reactivity in OCD and SAD while anticipating and perceiving unspecific emotional stimuli. While differential neurobiological responses between OCD and SAD when processing specific stimuli are evident from the literature, differences were less pronounced using unspecific stimuli. This could indicate a disturbance of emotion regulation common to both OCD and SAD.
