SUBRAMANI, P et al. Neuroregression in an infant: A rare cause. S. Afr. j. child health [online]. 2015, vol.9, n.2, pp.59-60. ISSN 1999-7671.  https://doi.org/10.7196/SAJCH.882.

Neuroregression in infants has diverse aetiologies, and vitamin B12 deficiency is a rare one. Infantile vitamin B12 deficiency is usually secondary to maternal pernicious anaemia or maternal vegetarian diet. We report a 10-month-old infant with developmental regression secondary to vitamin B12 deficiency. Her mother was a strict vegetarian and the patient was exclusively breastfed. Clinical symptoms normalised after vitamin B12 supplementation.
