Eating Disorders and Tourette Syndrome: A Case Series of Comorbidity and Associated Obsessive-Compulsive Symptomatology

Abstract

AbstractThere is a well-established overlap in phenomenology between anorexia nervosa and obsessive-compulsive disorder, and between obsessive-compulsive symptoms and Tourette syndrome (TS). Five cases of eating disorders in patients with obsessive-compulsive symptoms and TS are presented. The identification of four similar cases in the literature putatively marks a subset of eating disorders with a link to TS and to obsessive-compulsive symptomatology. This association may reflect a common underlying neurobiologic imbalance.
