Obsessive-Compulsive Disorder (OCD) is an anxiety disorder and one of the most misunderstood mental health issues. OCD generally causes significant distress and at times can observe hours of a personтАЩs day performing rituals. Often times if a person shows tendencies to be neat and systematized, we attribute them to OCD. Psychologists canтАЩt find out what exactly causes OCD, but it comes into view that genetics often play a role in those diagnosed with OCD.
