Greater amyloid burden in cognitive networks in preclinical Alzheimer's disease.
BackgroundIn preclinical Alzheimer's disease (pAD), regional patterns of amyloid-β (Aβ) deposition are well characterized but have not been systematically compared across functional networks.ObjectiveDetermine how Aβ accumulation in functional networks ("network-amyloid burden" [NAB]) varies by age, network type (cogni...
