This document discusses the psychoanalytic treatment of obsessive compulsive disorder (OCD). It provides an overview of OCD based on the DSM-IV criteria and conventional treatments including medications and cognitive behavioral therapy. It then outlines Freud's perspective on "obsessional neurosis" and the contemporary psychoanalytic view of OCD relating to attachment styles, defense mechanisms, and addressing the unconscious meaning behind symptoms through transference in therapy. The conclusion states that psychoanalytic treatment may benefit some individuals with OCD, especially those whose physical symptoms represent unconscious conflicts, and may serve as an alternative for those not helped by traditional approaches.
