Vitamin B12, cognition, and brain MRI measures: A cross-sectional examination

In the article “Vitamin B12, cognition, and brain MRI measures: A cross-sectional examination” by C.C. Tangney et al. (Neurology® 2011;77:1276–1282), there is a typographical error in the third paragraph of the Discussion section. On page 1280, in the right-hand column, second paragraph, the fourth sentence should read “In a British cohort where mandatory folate fortification is not in place, a comprehensive set of vitamin B12 markers were examined in association with brain atrophy over 5 years in 107 older adults.” The authors regret the error.
