Body Dysmorphic Disorder (BDD) is a mental disorder in which a person is preoccupied by a very slight physical anomaly or an imagined defect in his or her appearance. It is associated with Obsessive Compulsive Disorder (OCD). Treatment of BDD usually reduces symptoms of the disorder, but some people's symptoms regress only for a short time and then reappear. Drugs that will reduce the risk of BDD-relapse are needed. Escitalopram, also known as Lexapro, is a serotonin reuptake inhibitor (SRI). It is an oral drug used to treat depression and general anxiety disorder. Its ability to prevent relapse of BDD has not yet been studied. This study will evaluate the relapse-prevention rate of escitalopram for the treatment of BDD.

The study will start with an open-label phase, during which all participants will receive escitalopram for 14 weeks. Study visits will occur once weekly for the first month and once every other week for the remainder of the 14 weeks. At the end of this initial phase, those who show improvement will continue into a double-blind phase. The remaining participants will be randomly assigned to receive either escitalopram or placebo for an additional 6 months. Study visits will occur once every other week, with an additional visit at Week 15. Participants' improvement or return of BDD-related symptoms will be assessed. Throughout the 6 months, any participant showing relapse will be referred to alternate treatment.
