Physical activity (PA) has emerged as a possible modifier of these AD-related pathological changes. Consequently, the aim of this study was to cross-sectionally examine the relationship between objectively measured PA and CSF levels of A¦Â42 and tau in asymptomatic late-middle-aged adults at risk for AD %K Alzheimer's disease %K CSF biomarkers %K Exercise %K Physical activity %K Sedentary behavior %U https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5842318/
