Popis: Abstract INTRODUCTION We assessed whether midlife sensory and motor functions added to prediction models using the Cardiovascular Risk Factors, Aging, and Incidence of Dementia Score (CAIDE) and Framingham Risk Score (FRS) improve risk predictions of 10‐year changes in biomarkers of neurodegeneration and Alzheimer's disease. METHODS Longitudinal data of N = 1529 (mean age 49years) Beaver Dam Offspring Study participants from baseline, 5‐year, and 10‐year follow‐up were included. We tested whether including baseline sensory (hearing, vision, olfactory) impairment and motor function measures improves CAIDE or FRS risk predictions of 10‐year incidence of biomarker positivity of serum‐based neurofilament light chain (NfL) and amyloid beta (Aβ)42/Aβ40 using logistic regression. RESULTS Adding sensory and motor measures to CAIDE‐only and FRS‐only models significantly improved NfL and Aβ42/Aβ40 positivity predictions in adults above the age of 55. DISCUSSION Including midlife sensory and motor function improved long‐term biomarker positivity predictions. Non‐invasive sensory and motor assessments could contribute to cost‐effective screening tools that identify individuals at risk for neurodegeneration early to target interventions and preventions. Highlights Sensory and motor measures improve risk prediction models of neurodegenerative biomarkers Sensory and motor measures improve risk prediction models of AD biomarkers Prediction improvements were strongest in late midlife (adults >55 years of age) Sensory and motor assessments may help identify high‐risk individuals early
