A K Tripathi et al. Indian J Hematol Blood Transfus. 2010 Sep.

Abstract

Cyanocobalamin deficiency is not rare in India. Patients present with megaloblastic anemia, pancytopenia and sometimes neuropsychiatric manifestations. Subacute combined degeneration of the cord, peripheral neuropathy, dementia, psychotic depression and paranoid schizophrenia are well reported. We are reporting a case of cyanocobalamine deficiency anemia who presented with acute psychosis which readily reversed on cyanocobalamin replacement.

Keywords: Cynocobalamine deficiency; Megaliblastic anemia; Psychosis; SACD; Vitamin B12.
