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.

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.

This study examines the association between hematocrit levels and dementia risk in a multiethnic cohort, finding that lower hematocrit is linked to increased dementia risk, with no mediation by cerebral small vessel disease.

The paper examines the relationship between hippocampal structure and episodic memory in oldest-old adults, finding a significant correlation between hippocampal morphology and memory performance.
