Target
Function
Levels were significantly higher in patients with biomarker-confirmed AD than in patients with non-AD dementia and unaffected controls, including in a cohort with postmortem confirmed diagnoses and in a memory clinic cohort with high disease heterogeneity. In this multicenter study, we examined the association of blood BD-tau with longitudinal cognitive changes and AD-characteristic brain atrophy rates along preclinical, MCI, and dementia stages of AD using four independent cohorts. We further assessed whether BD-tau concentrations increase with the co-occurrence of A+ and N+ abnormalities across the AD disease continuum and whether such A/N classification can be achieved using blood-based biomarkers to identify individuals at risk for cognitive decline and atrophy in the short term. In addition, we assessed the impact of genetic risk, comorbidities, and demographic factors, including ethnic self-identification, on plasma BD-tau concentrations and their clinical performance.
