Developing early vulnerable area aggregates for PET detection of beta‐amyloid based on young and middle‐aged adults from the Framingham Heart Study

As Alzheimer’s clinical trials shift earlier and earlier in the disease process, current global PET measures of beta‐amyloid (Aβ) positivity may be insufficient for detecting the earliest Aβ deposits. Regional PET measures may better detect the earliest deposits. Previous efforts to identify early‐accumulating regions have inferred which regions may be most vulnerable based on older adults. Our aim was to identify early vulnerable areas by looking earlier in the lifespan.
