Objectively-defined subtle cognitive decline (Obj-SCD) and plasma phosphorylated-tau181 (p-tau181) are promising early Alzheimer's disease (AD) markers. However, associations between Obj-SCD and p-tau181, and their combined prognostic potential, are unknown. Baseline and 4-year longitudinal p-tau181 changes were compared across cognitively unimpaired (CU; =402), Obj-SCD ( =199), and mild cognitive impairment (MCI; =346) groups. CU and Obj-SCD participants were further classified as p-tau181-positive or negative. CU and Obj-SCD has lower
