Abstract:Introduction: Alzheimers disease (AD) is a neurodegenerative disorder characterized by changes in beta amyloid (Abeta) and tau as well as changes in cerebral glucose metabolism and gray matter volume. This has been categorized as three distinct stages of amyloid, tau, and neurodegeneration. Past studies have shown asymmetric Abeta accumulation and its association with asymmetric cerebral metabolism in preclinical AD. We analyzed data to replicate these findings and extend them to associations with gray matter … Show more
