title: The neurology of vitamin B12 deficiency. Metabolic mechanisms.
abstract: The widely held view that the neurological and haematological complications of vitamin-B12 deficiency have different metabolic mechanisms appears unsound. It is suggested that the metabolic mechanisms involved are similar and that the neurological manifestations are the result of a secondary disturbance in folate metabolism as has already been postulated for the megaloblastosis.
