SuperAger Brains Shrink More Slowly 

Summary: Typical agers lose brain volume twice as fast as SuperAgers, a new study reports.

Over the course of the 18-month study, normal agers lost volume in the cortex twice as fast as SuperAgers, a rare group of people aged 80 and above whose memories are as sharp as those of healthy persons decades younger./.../
