Abstract

Objective: Vitamin B12 (cobalamin) is a key component in the catabolism of monoamines. B12 deficiency is associated with various neuropsychiatric disorders and may be more frequent in psychiatric inpatients. The authors describe a case report of a newly admitted and relatively young patient (52 years old) with organic psychosis secondary to vitamin B12 deficiency. No other overt clinical features of cobalamin deficit were observed. Symptoms were resolved with B12 and folate replacement. The patient's mental status remained stable over the 3 months after the treatment. The authors note that organic mental changes were reversible with B12 replacement. Conclusions: The authors propose that determination of serum vitamin B12 and folic acid levels should be recommended as routine screening in all new admissions of psychiatric patients regardless of their age or previous state of health.
