Memory and executive function in older adults: relationships with temporal and prefrontal gray matter volumes and white matter hyperintensities.


Forty-eight healthy adults aged 65-85 were recruited for structural magnetic resonance scans after an extensive neuropsychological battery that ensured a high degree of variability across the sample in performance on long-term memory tests, and on tests traditionally thought to rely on prefrontal cortex. Gray matter volumes were measured for three gyri in… (More)
