The paper examines sex-specific gene expression associations with Alzheimer's disease neuropathology and cognitive performance using bulk transcriptomic data from 767 individuals.

The paper identifies sex-specific genetic loci associated with memory, executive functioning, and language performance in older adults through genome-wide meta-analyses.

This study examines the association between APOE genotype and cognitive resilience in SuperAgers, finding lower APOE-ε4 and higher APOE-ε2 frequencies in non-Hispanic White SuperAgers compared to controls and Alzheimer's cases.

The paper examines how sex, race, and APOE-ε4 allele status affect white matter microstructure across multiple aging and Alzheimer's disease cohorts.

This paper uses deep learning to predict brain age from MRI data and finds it correlates with cognitive impairment and decline.

This study analyzes diffusion MRI data from 1184 participants to quantify age-related changes in white matter microstructure and macrostructure, finding that macrostructural features show more heterogeneous age-related decline.

This study identifies genetic variants and pathways associated with cognitive resilience to Alzheimer's disease, finding a novel locus linked to bile acid metabolism and methylation changes.

The paper investigates how free-water metrics in medial temporal lobe white matter tracts relate to cognitive decline, finding they add unique predictive value beyond hippocampal volume.
