Cobalamin deficiency increases with advancing age. The cut-off point of serum
concentration should be raised, because many elderly people with" normal" serum vitamin …

BACKGROUND:: Standard treatment of cobalamin (vitamin B12) deficiency involvesregular
(1000 μg/mo) IM cyanocobalamin administration. It has been suggested that high-dose (> …

Elderly persons are more likely to have low values for serum and erythrocyte folate, and for
serum cobalamin. Many of those with low vitamin levels have biochemical abnormalities …

Background: To date, only case reports or small studies have documented the syndrome of
food-cobalamin malabsorption in specific populations of patients or situations. In this paper …

Background. Low serum cobalamin levels are often found in apparently normal older
subjects. A major worry of leaving cobalamin deficiency untreated is that it may lead to …

In order to determine the relevance of low vitamin B12 concentration in elderly persons
(greater than 65 years), serum vitamin B12 levels were measured in 292 consecutive …

Cobalamin levels are frequently low in patients with dementia, but it is unclear if they
represent definable deficiency and what the mechanisms are. Therefore, patients being …

Cobalamin (vitamin B 12) deficiency is particularly common whatever the age of the patient,
but may be unrecognized because of its subtle clinical manifestations, although these can …

Abstract Background. Mild cobalamin (Cbl) deficiency is frequently found in older persons
and is associated with cognitive and cerebral abnormalities. The effects of Cbl …

Food-cobalamin malabsorption is marked by the inability to release cobalamin from food,
which therefore cannot be taken up by intrinsic factor for absorption. The defect is not …
