Obsessive-Compulsive Disorder (OCD) and Obsessive-Compulsive Related Disorders (OCRD)
0
This activity covers OCD and its related conditions (OCRDs). OCD involves persistent intrusive obsessions and repetitive compulsions that are time-consuming, distressing, and not better explained by another cause. The activity also touches on Body Dysmorphic Disorder, Hoarding Disorder, Trichotillomania, and Excoriation Disorder — each sharing core features with OCD (repetitive behaviors, intrusive thoughts) while differing in primary symptom focus and underlying mechanisms.
