    Inverse Association between Serum Methylmalonic Acid Levels and Cognitive Function in the Elderly

    Reference:

    "Methylmalonic acid and cognitive function in the Medical Research Council Cognitive Function and Ageing Study," McCracken C, Hudson P, et al, Am J Clin Nutr, 2006; 84(6): 1406-11. (Address: University Department of Psychiatry, Royal Liverpool University Hospital, Liverpool, United Kingdom).

    Summary:

    In a cross-sectional study involving 84 nondemented participants (over 69 years of age) from the Welsh cohort of the Medical Research Council's Cognitive Function and Aging Study, likely metabolically significant vitamin B12 deficiency - indicated by elevated serum levels of methylmalonic acid (MMA; a related metabolic marker of vitamin B12 deficiency) - was associated with lower cognitive scores of language comprehension and expression. Additionally, a high prevalence of likely metabolically significant vitamin B12 deficiency was observed in the elderly participants. Cognitive status was assessed by the Mini-Mental State Examination (MMSE) and the Cognitive Section of the Cambridge Mental Disorders of the Elderly Examination (CAMCOG). Likely metabolically significant vitamin B12 deficiency was observed in 43% of the participants. After adjusting for age and education, higher MMA levels were associated with lower MMSE scores. Additionally, an inverse association was foun d between serum MMA levels with CAMCOG scores of ideational praxis, language comprehension, and language expression. Furthermore, a weak but significant correlation was observed between serum folate with language, remote memory, and constructional and ideational praxis scores. Thus, the authors of this study conclude, "The high prevalence of likely metabolically significant vitamin B-12 deficiency in the elderly is associated with lower cognitive function scores and particularly with lower scores of language comprehension and expression."
