Visual and brainstem auditory evoked potentials in infants with severe vitamin B-12 deficiency

Abstract

Background/aim: Vitamin B-12 plays an important role in the development of mental, motor, cognitive, and social functions via its role in DNA synthesis and nerve myelination. Its deficiency in infants might cause neuromotor retardation as well as megaloblastic anemia. The objective of this study was to investigate the effects of infantile vitamin B-12 deficiency on evoked brain potentials and determine whether improvement could be obtained with vitamin B-12 replacement at appropriate dosages.
