Obsessive-compulsive disorder (OCD) is a chronic and debilitating condition that impacts over 2% of the global population. Characterized by uncontrollable, reoccurring thoughts (obsessions) and behaviors (compulsions) that the patient feels compelled to repeat over and over, OCD was previously ranked by the World Health Organization (WHO) to be one of the top 10 debilitating medical conditions associated with a decreased quality of life and loss of income. It is now listed among other anxiety-based disorders, which together rank as the sixth leading cause of worldwide disability.
