Obsessive-compulsive disorder (OCD) is considered one of the most difficult psychiatric conditions to treat due to its diverse symptomatology, the difficulties of establishing a relationship with patients and the rigidity of most patients. OCD has been, following recent developments in cognitive neuroscience, neuropsychology and neuro-imaging, removed from the group of anxiety disorders in the DSM-5 and given a category of its own. Meanwhile, no truly novel theoretical constructions of the disorder have been published in psychoanalytic literature ever since Freud's seminal work. The treatment of OCD-patients has been gradually relegated to pharmacotherapy and cognitive therapy and outside of psychoanalytic thinking. In the present study, I shall first, through a segment from a psychoanalytic session, review relevant neuropsychological findings on OCD and then interpret these findings from a psychoanalytic point of view. As a second step, I shall attempt to redefine OCD in the framework of object relations theory with the help of the theory of developmental positions conceived by Klein, introducing the concept of an obsessive position. I shall differentiate the obsessive ego-state from the realistic one and discuss the differences between the two ego-states. Through the introduction of an obsessive ego-state, I suggest redefining OCD as a disorder of personality organization and ego-organization. Furthermore, I am arguing for a need to modify psychoanalytic techniques in the treatment of OCD-patients. The segment of the therapeutic session offers a glimpse into this modified technique.
