Background: Deficiencies in folate and vitamin B12 have been associated with neurodegenerative disease. Objective: To examine the association between rates of age-related cognitive change and dietary intakes of folate and vitamin B12. Design: Prospective study performed from 1993 to 2002. Setting: Geographically defined biracial community in Chicago, Ill. Participants: A total of 3718 residents, 65 years and older, who completed 2 to 3 cognitive assessments and a food frequency questionnaire. Main Outcome Measure: Change in cognitive function measured at baseline and 3-year and 6-year followups, using the average z score of 4 tests: the East Boston Tests of immediate and delayed recall, the Mini-Mental State Examination, and the Symbol Digit Modalities Test.
Results: High folate intake was associated with a faster
rate of cognitive decline in mixed models adjusted for multiple risk factors. The rate of cognitive decline among persons in the top fifth of total folate intake (median, 742
