Olfactory dysfunction is a common symptom of OCD, but all previous studies have focused on late\u2010onset OCD (LOCD).<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>The current study compared olfactory identification ability in EOCD patients and age\u2010matched and sex\u2010matched LOCD patients and healthy controls. Thirty patients with EOCD, 30 patients with LOCD and 30 healthy controls were included in the study. Olfactory function was measured using the University of Pennsylvania Smell Identification Test. The Logical Memory and Visual Reproduction components of the Revised Wechsler Memory Scale were used to evaluate verbal and visual memory.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>There were significant differences in olfactory identification ability between the three groups.
