Predictive PET

Understanding the dynamic of the two major hallmark of Alzheimer’s disease (AD), tau protein and β-amyloid, in the brain could allow better disease management. The use of positron emission tomography (PET) with specific radiotracers allows the visualization of tau-containing neurofibrillary tangles and β-amyloid plaques in vivo. Now, La Joie et al. performed longitudinal analysis of tau-PET and β-amyloid–PET in 32 patients with AD starting at early disease stage and correlated the signal with brain atrophy at later stages. In this cohort, tau-PET, but not β-amyloid–PET, signal could predict brain atrophy at later stages. Tau-PET might be useful for predicting disease progression and for designing and evaluating new therapies.
