Backgrounds: Apolipoprotein E epsilon-4 (APOE ε4) allele, methylenetetrahydrofolate reductase (MTHFR C677T), and methionine synthase (MTR A2756G) were tested their associations with cognitive impairment in people with late-life depression (LLD). Methods: People with LLD were assessed by mini-mental state examination and were examined the distribution of APOE ε4 allele, MTHFR, and MTR polymorphisms. Results: Odds ratio of MTR 2756 AA to MTR 2756 AG and GG genotypes for the risk of cognitive impairment was 5.80 (95% confidence interval=1.18-28.50; P=0.03). Conclusion: People with LLD carrying MTR2756 AA genotype have higher risk of cognitive impairment than those carrying G allele.
