Neural Mechanisms Of Symptom Dimensions During Provocation In Obsessive-Compulsive Disorder

Obsessive-compulsive disorder (OCD) is highly heterogenous, yet it remains unclear how this heterogeneity may be related to differential neurocircuitry. This study investigated neural mechanisms associated with symptom heterogeneity in OCD by examining the relationship between fMRI activation during a provocation task and severity of four different symptom dimensions in OCD.
