Abstract

AbstractAlzheimer's disease (AD) is a chronic and progressive neurodegenerative disorder with long preclinical and prodromal phases in older people. Molecular imaging is a promising approach for noninvasive in vivo identification and tracking pathophysiological changes. In particular, nuclear neuroimaging in AD has extended beyond traditional evaluation of brain perfusion and glucose metabolism, and has achieved substantial progress over the past 2 decades. To gain a comprehensive understanding of nuclear neuroimaging with different targets in the brain, this review provides an overview of the literature on the current status and recent progress of the development of radioligands for definitive and differential diagnosis of AD.
