The research community now has a new framework toward developing a biologically-based definition of Alzheimer’s disease. This proposed “biological construct” is based on measurable changes in the brain and is expected to facilitate better understanding of the disease process and the sequence of events that lead to cognitive impairment and dementia. With this construct, researchers can study Alzheimer’s, from its […]
