title: Dietary Deficiency of Cobalamin Presented Solely as Schizoaffective Disorder in a Lacto-Vegetarian Adolescent.
abstract: Cobalamin is an important nutrient. It is not synthesized in human body and supplied only in nonvegetarian diet. Its deficiency reported with range of psychiatric disorders. Only four pediatric cases have been reported as psychiatric disorders. Authors report a case of dietary deficiency of cobalamin presenting solely as schizoaffective disorder without hematological/neurological manifestations. Early diagnosis and treatment of cobalamin deficiency is an opportunity to reverse pathophysiology. This case highlights the importance of diet history and serum cobalamin level in atypical psychiatric presentations.
