Your Brain Doesn't Look a Day Past 70! Cross-Sectional Associations with Brain-Predicted Age in the Cognitively-Intact Oldest-Old

Mark K. Britton, Hannah Hoogerwoerd, Joshua Juhasz…·Joseph M. Gullett

The paper assesses brain-predicted age differences in cognitively-intact oldest-old adults and finds no association between brain aging and cognitive performance or health history, suggesting high cognitive reserve and survivorship effects.

"Surviving and Thriving": Evidence for Cortical GABA Stabilization in Cognitively-Intact Oldest-Old Adults

Mark K. Britton, Greg Jensen, Richard A.E. Edden…·Eric C. Porges

The paper examines age-related GABA level changes in cognitively-intact oldest-old adults, finding that GABA decline flattens after age 80, suggesting a link between GABAergic function and successful cognitive aging.
