Vitamin B12 and brain development.
This is a report of a 1 1/2-year-old male with megaloblastic anaemia and a progressive neurological disorder clinically resembling leucodystrophy. The child was exclusively breast fed and his mother had been a strict vegetarian for more than 4 years before the child was born. After Vitamin B12 therapy the anaemia disappeared and the neurological condition dramatically improved.
