H. Baker et al., Lack of effect of 1 year intake of a high-dose vitamin and mineral supplement on cognitive function of elderly women, GERONTOLOGY, 45(4), 1999, pp. 195-199
Objective: To determine if long-term, high-vitamin supplementation could re
verse cognitive malfunction in old people. Methods: We performed a longitud
inal study relating the 12-month outcome to baseline va lues. Twenty non-vi
tamin-deficient elderly females with a Folstein mini mental state examinati
on score indicating cognitive malfunctions were recruited to ascertain if f
eeding a high-dose vitamin-mineral supplement for 1 year could, by mass vit
amin action, reverse some existing cognitive malfunctions. Ten females were
fed a high-dose vitamin-mineral supplement pill with each of three daily m
eals for 1 year; the other 10 did not receive this supplementation, Twelve
blood vitamin analyses and a Folstein mini mental state examination were pe
rformed for each of the 20 subjects before and after 1 year; each subject s
erved as its own control, Results: No improvement in cognitive malfunction
was noted despite elevation of blood vitamins, Conclusion: Feeding of a hig
h-dose vitamin and mineral supplement for 1 year did not improve cognitive
malfunction in non-vitamin-deficient elderly in this study.
