Therefore, we systematically compared longitudinal changes in A/T/N biomarkers (amyloid-positron emission tomography [PET], tau-PET, plasma phosphorylated tau at threonine 217 [p-tau<sub>217</sub>], and magnetic resonance imaging) for tracking cognitive changes.<h4>Methods</h4>We analyzed longitudinal biomarker and cognitive change rates from the Alzheimer's Disease Neuroimaging Initiative (N = 141) and Anti-Amyloid Treatment in Asymptomatic Alzheimer's (A4) and Longitudinal Evaluation of Amyloid Risk and Neurodegeneration (LEARN) (N = 151), estimated using linear mixed models. The gene discussed is MAPT; the disease is amyloidosis.
