CUSTODIO CAPUNAY, Nilton et al. Dementia due to vitamin B12 deficiency - Is there always a response to therapy?. Acta méd. peruana [online]. 2011, vol.28, n.4, pp.221-223. ISSN 1728-5917.

Introduction: Dementia due to vitamin B12 deficiency is a reversible condition which occurs more frequently in the elderly. Clinical cases: We present three elderly patients who were diagnosed with dementia and low serum B12 levels, and they received therapy with hydroxocobalamin. Two patients clinically improved and only one had normalized his vitamin B12 blood levels with no clinical improvement, possibly because of the coexistence of Alzheimer’s disease.

Palabras clave : Dementia; vitamin B12.
