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.

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.

This study finds that adult brain age is more influenced by early life factors like birth weight and polygenic scores than by longitudinal brain decline.

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.

The paper examines how self-reported sleep relates to hippocampal atrophy across adulthood using data from the Lifebrain consortium and UK Biobank, finding that worse sleep is linked to faster hippocampal volume loss over time.
