SuperAgers, aged 80 and above — but with memories that are as sharp as those of healthy persons decades younger — have distinctly different looking brains than those of normal older people, according to new Northwestern Medicine research.
Understanding Superagers’ unique “brain signature” may enable scientists to decipher the genetic or molecular source and develop strategies to protect the memories of normal aging persons, as well as treat dementia.
Published Jan. 28 in the Journal of Neuroscience, the study is the first to quantify brain differences of SuperAgers and normal older people.
Cognitive SuperAgers were first identified in 2007 by scientists at Northwestern’s Cognitive Neurology and Alzheimer’s Disease Center at Northwestern UniversityFeinberg School of Medicine./.../
