What biological mechanisms account for the additional predictive value when combining plasma p-tau217 and tau-PET?

OPEN

Combined biomarker models outperformed single-biomarker approaches, but the study doesn't explain what distinct pathological processes each biomarker captures. Understanding these complementary mechanisms could reveal new therapeutic targets and optimize biomarker strategies for preclinical AD.
