Unraveling the Tau Puzzle: A Brief Discussion on Biomarkers in Alzheimer's Disease.

This commentary provides an in-depth analysis of a recently published systematic review on 'Biomarkers of Tau Pathology in Alzheimer's Disease', elucidating insights into its implications for the field. This meta-analysis highlights the potential of plasma and CSF p-tau 181/231 as promising, non-invasive, and cost-effective diagnostic tools for patients suffering from AD continuum. The study comprehensively reviews the diagnostic potential of these p-tau isoforms, shedding light on their role in the precision diagnosis of Alzheimer's disease. Here we discuss the significance of these findings and the methodological nuances, emphasizing broader implications for advancing personalized medicine in neurodegenerative disorders.
