Age-dependent associations of sleep duration and insomnia symptoms with cognitive decline across five decades of adult life: a multi-cohort longitudinal study

Quote: Interpretation The cognitive implications of sleep disturbances vary by life stage. In midlife, difficulty falling asleep was associated with faster cognitive decline, supporting its role as a modifiable risk factor. In advanced age, the reversal is consistent with diminished arousal capacity accompanying prodromal dementia.

Exploring multifaceted mental resilience from the perspectives of sleep and circadian rhythm in healthy adults

Quote: Conclusions Sleep and circadian metrics, specifically frontal slow waves and REM theta activity, attenuated overall occipital spectral power during sleep, and earlier dim light melatonin onset time, represent quantifiable targets that may serve to improve resilience and stress-related mental health in adults. Longitudinal and interventional studies are needed to establish whether sleep interventions can be endorsed as evidence-based approaches for resilience enhancement.
