Sleep duration and brain structure - phenotypic associations and genotypic covariance

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.

Self-Reported Sleep Relates to Microstructural Hippocampal Decline in β-Amyloid Positive Adults Beyond Genetic Risk

This study finds that worse self-reported sleep relates to faster hippocampal microstructural decline in β-amyloid positive adults, independent of genetic risk.

Self-reported sleep problems are related to cortical thinning in aging but not memory decline and amyloid-β accumulation - results from the Lifebrain consortium

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.

Mid-life and late life activities and their relationship with MRI measures of brain structure and functional connectivity in the UK Biobank cohort

This study examines the relationship between mid-life and late life leisure activities and MRI measures of brain structure and functional connectivity in older adults from the UK Biobank.

Self-reported sleep relates to hippocampal atrophy across the adult lifespan - results from the Lifebrain consortium

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.
