Short sleep is held to cause poorer brain health, but is short sleep associated with higher
rates of brain structural decline? Analysing 8,153 longitudinal MRIs from 3,893 healthy …

Background Short and long sleep duration have been linked with poorer cognitive
outcomes, but it remains unclear whether these associations are causal. Methods We …

Sleep is essential for life, including daily cognitive processes, yet the amount of sleep
required for optimal brain health as we grow older is unclear. Poor memory and increased …

Sleep duration, psychiatric disorders and dementias are closely interconnected in older
adults. However, the underlying genetic mechanisms and brain structural changes are …

Given that sleep deprivation studies consistently show that short sleep causes
neurocognitive deficits, the effects of insufficient sleep on brain health and cognition are of …

Importance An association between sleep duration and the trajectory of cognitive decline
has not been conclusively demonstrated. Objective To investigate the association between …

Many sleep less than recommended without experiencing daytime sleepiness. According to
prevailing views, short sleep increases risk of lower brain health and cognitive function …

Epidemiological studies show a positive association between adequate sleep and good
health. Further, disrupted sleep may increase the risk for CNS diseases, such as stroke and …

We examined whether sleep quality and quantity are associated with cortical and memory
changes in cognitively healthy participants across the adult lifespan. Associations between …

Objectives Daytime napping has been associated with cognitive function and brain health in
observational studies. However, it remains elusive whether these associations are causal …
