• 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.
  • Their unusual brain signature has three common components when compared with normal persons of similar ages: a thicker region of the cortex; significantly fewer tangles (a primary marker of Alzheimer’s disease), and a whopping supply of a specific neuron — von Economo — linked to higher social intelligence.
  • "Von Economo neurons play a critical role in the rapid transmission of behaviorally relevant information related to social interactions,” Geula said, “which is how they may relate to better memory capacity.” These cells are present in such species as whales, elephants, dolphins and higher apes.
