Despite global efforts to understand and ultimately assess, diagnose, and treat Alzheimer's disease (AD) more effectively, a consensus definition of AD still does not exist.  In 2018, the National Institute of Aging – Alzheimer’s Association (NIA-AA) Research Framework recommended that we should shift the definition of AD from a syndrome (i.e., the cognitive/behavioral symptoms that individuals present with) to a purely biological construct, specifically the presence of βamyloid deposition, pathologic tau, and neurodegeneration (the "A/T/N" model).  In this episode, we talk to Dr. Adam Brickman about the NIA-AA Research Framework biological definition of AD, the role of vascular contributions, assumptions about the amyloid hypothesis, and implications of not including the clinical syndrome in the diagnosis of AD.
