Recurrent Syncopal Episode and Undetectable Vitamin B12

Abstract

Syncope is a common cause of hospital admissions, with a high prevalence found in people 10-30 years of age, and in those 70 years and older. The condition often requires an extensive yet unrevealing workup. Vitamin B12 deficiency, however, is rarely thought to be the primary root of recurrent syncope. We had a case of vitamin B12 deficiency without findings of anemia, which presented as a recurrent syncope in an otherwise relatively young healthy man.
