Obsessive Compulsive Disorder (OCD) is an anxiety disorder with two essential characteristics: Recurrent and persistent thoughts ideas and feelings (referred to as obsessive thoughts) Repetitive, ritualised behaviours (referred to as compulsions or compulsive behaviours) Attempts to resist a compulsive behaviour produces mounting tension and anxiety, which are relieved immediately by giving in and carrying out the behaviour. The term is not properly used for behaviours like excessive drinking, gambling, eating etc. on the grounds that the ‘compulsive gambler’ for example, actually derives considerable pleasure from gambling (it’s the losing that hurts); one burdened with a true Obsessive Compulsive Disorder (OCD) derives no pleasure from it other than the release of tension.
