Teenagers with OCD have obsessions and/or compulsions. An obsession refers to recurrent and persistent thoughts, impulses, or images that are intrusive and cause severe anxiety or distress. Compulsions refer to repetitive behaviors and rituals (like hand washing, hoarding, ordering, checking) or mental acts (like counting, repeating words silently, avoiding). The obsessions and compulsions also significantly interfere with the teen’s normal routine, academic functioning, usual social activities, or relationships.
