TL;DR: The results suggest that the Montreal Cognitive Assessment may be susceptible to practice effects, particularly between the first and second administrations, and should be taken into consideration when repeatedly employing the MoCA to screen for cognitive status in healthy older adults.

TL;DR: Examination of white matter tract integrity and cognitive performance associated with BMI in 62 healthy older adults revealed that elevated BMI was associated with lower fractional anisotropy in the uncinate fasciculus, though there was no evidence of an age by BMI interaction relating to FA in this tract.

TL;DR: It is suggested that aging has a significant and differential impact on GM/WM diffusion in healthy older adults, which may explain a modest degree of cognitive variability at specific time points during older adulthood.

TL;DR: Diffusion tensor imaging results demonstrate that white matter abnormalities are evident among individuals with probable MCI in regions beyond those commonly associated with Alzheimer’s disease and anterior brain aging patterns.

TL;DR: Preliminary evidence is provided that CETP II homozygosity is a predisposing risk factor for gray matter abnormalities in posterior brain regions in healthy older adults, independent of an ApoE4 allele.
