We also determined the likelihood of having mild cognitive impairment (MCI) or dementia in warfarin users, compared to nonusers.</p><p><strong>Methods: </strong>We used data from 381 autopsied participants, 76% female, mean (SD) age at death 92(6) y, in the Rush Memory and Aging Project (MAP) in whom MK-4 was measured in 4 brain regions: the mid-frontal and temporal cortices, anterior watershed (AWS), and cerebellum. Brain MK-4 concentrations were compared between those treated with warfarin and those not treated, using linear regression adjusted for age, sex, and cognitive diagnosis at death. The association of warfarin use prior to death with cognitive diagnosis at death was evaluated using logistic regression, adjusted for age, sex, education, and apolipoprotein E4 status.</p><p><strong>Results: </strong>Warfarin users [n = 73, median (IQR) duration of warfarin use = 585 (479-656) d] had 68%-79% lower brain MK-4 concentrations in all measured regions, and the mean across all regions, compared with nonwarfarin users (unstandardized β -1.538 to -1.140; all P < 0.001, fully adjusted). The likelihood of having MCI or dementia, compared with no cognitive impairment, at death did not significantly differ between those treated with warfarin prior to death and those not [OR (95% confidence interval) for MCI: 0.82 (0.41, 1.62), dementia: 1.04 (0.57, 1.93), fully adjusted].</p><p><strong>Conclusions: </strong>These findings suggest that warfarin treatment influences MK-4 concentrations in the human brain. Future studies are needed to elucidate the mechanisms underlying this effect and its clinical implications.</p>","PeriodicalId":16620,"journal":{"name":"Journal of Nutrition","volume":" ","pages":""},"PeriodicalIF":3.7,"publicationDate":"2025-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144023689","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
