Error-Related Brain Activity Dissociates Hoarding Disorder from Obsessive-Compulsive Disorder

摘要

BackgroundObsessive-compulsive disorder (OCD) is associated with an abnormally large error-related negativity (ERN), an electrophysiological measure of error monitoring in response to performance errors, but it is unclear if Hoarding Disorder (HD) also shows this abnormality. This study aimed to determine whether the neurophysiological mechanisms underlying error monitoring are similarly compromised in HD and OCD.
