The presentation will begin by discussing the etiology and diagnostic criteria of obsessive compulsive disorder (OCD) and anorexia (AN) and will then include the medical and psychiatric issues and concerns associated with OCD and AN. Often AN and OCD present diagnostic challenges and pitfalls, including which diagnosis is primary and which diagnosis is more imperative to treat. Presenters will discuss the evidence-based treatments, including the role of psychopharmacological treatment and highlight the importance of an outpatient multidisciplinary team approach to include psychiatric management, individual therapy, family therapy (especially the Maudsley approach), group therapy and nutritional therapy. Finally, there will be a case presentation which will discuss how the care was delivered and take home points for therapists to consider. The case presentation will include discussions from all disciplines involved and will cover evidence-based diagnostic and treatment modalities.
