No doubt you’ve heard that it’s ‘‘normal’’ for old age to be associated with ga radual decline in both memory and brain mass. Maybe not so much. A study printed in the Journal of the International Neuropsychological Society reported the identification of some cognitive SuperAgers; individuals whose brains appeared immune to age-related memory impairment and cortical volume. SuperAgers were defined as individuals over age 80 with episodic memory performance at least as good as normative values for 50- to 65-year-olds. What did the SuperAgers brains look like? cerebral cortex was significantly thicker than their healthy age-matched peers and displayed no atrophy compared to the 50- to 65-year-old healthy group. Unexpectedly, a region of left anterior cingulate cortex was significantly thicker in the SuperAgers than in both elderly and middle-aged controls. The question now is how to identify specific factors that resulted in this.
