MAPT and Alzheimer disease: These findings build upon a previous publication that examined the relationship between Alzheimer’s disease biomarkers and neonatal hypoxia, where we reported that cord blood BD-tau is associated with indicators of foetal hypoxia, while p-tau217 levels may reflect a more general susceptibility to neurodevelopmental issues.29 In the present study, we contextualize these associations within biomarker changes observed in older individuals and Alzheimer’s disease.
