Alzheimer's disease can be reversed in animal models to achieve full neurological recovery

For over a century, Alzheimer's disease (AD) has been considered irreversible. Consequently, research has focused on disease prevention or slowing, rather than recovery. Despite billions of dollars spent on decades of research, ...

Brain's 'pulse generators' grow and shrink as memories are formed, study finds

Memories and learning processes are based on changes in the brain's neuronal connections, and as a result, in signal transmission between neurons.

Cell defect in exosomes linked to development of Alzheimer's

They're tiny particles—with potentially huge human consequences. Researchers from Aarhus University have identified a defect in the production of so-called exosomes in cells, associated with a mutation seen in dementia ...

Study of identical twins links faster aging to memory decline

New research from University of Virginia psychologists has found that "epigenetic clocks"—tools scientists use to estimate a person's biological age—can predict cognitive decline. The study, which focused on middle-aged ...
