Brain amyloid-beta (Aβ) plaques, a hallmark of the pathophysiology of Alzheimer's disease, have been associated with frailty. Whether the plasma Aβ markers show similar relationship with frailty is unknown. To investigate the prospective associations between plasma Aβ42/40 ratio and overtime frailty in community-dwelling older adults. From the 5-year Multidomain Alzheimer Preventive Trial (MAPT), we included 477 adults ≥70 years with available data on plasma Aβ42/40 ratio (lower is worse). Fried frailty phenotype (robust,
