This study investigates the relationship between brain atrophy and memory decline in aging using longitudinal data, finding a nonlinear association that intensifies with age and is influenced by APOE ε4 carriership.

This study assesses the reliability of structural brain change in cognitively healthy adults over time, finding that longer follow-up periods significantly improve reliability compared to increasing observation frequency.

The paper shows that higher genetic risk for Alzheimer's disease is linked to faster brain volume loss and memory decline in healthy adults.

The paper investigates the effects of short sleep on brain structure and cognitive function, finding that short sleepers without daytime tiredness have larger brain volumes but slightly lower cognitive scores.

The paper investigates how general cognitive ability relates to cortical brain volume changes over time, finding associations with both brain reserve and maintenance mechanisms.

This study examines the relationship between sleep duration and brain structure using MRI data, finding that 6.8 hours of sleep is associated with the most favorable brain outcomes, with genetic analyses suggesting homeostatic regulation of sleep duration.

The paper examines how education and income relate to brain and cognitive differences across European and US cohorts, finding heterogeneous effects and stronger associations in US samples.

The paper examines the relationship between self-reported sleep parameters and cortical thinning in aging, finding associations with specific brain regions but not with memory decline or amyloid-β accumulation.

A study shows that limiting screen device use after 9 pm improves sleep onset, duration, and daytime vigilance in adolescents, with genetic factors influencing the effect.
