Sleep is implicated in cognitive functioning in young adults. With increasing age, there are
substantial changes to sleep quantity and quality, including changes to slow-wave sleep …

A common but significant change associated with aging is a profound disruption to the daily
sleep-wake cycle. It has been estimated that as many as 50% of older adults complain about …

Multiple studies have examined associations between sleep and cognition in older adults,
but a majority of these depend on self-reports on sleep and utilize cognitive tests that assess …

Here we review the impact of obstructive sleep apnea (OSA) on biomarkers of Alzheimer's
disease (AD) pathogenesis, neuroanatomy, cognition and neurophysiology, and present the …

The investigation of time-of-day effects on cognitive performance began in the early days of
psychophysiological performance assessments. Since then, standardised, highly controlled …

Background Alzheimer's disease (AD) pathology impairs cognitive function. Yet some
individuals with high amounts of AD pathology suffer marked memory impairment, while …

Healthy aging is characterized by a diminished quality of sleep with decreased sleep

The usual assessment of general mental ability (or intelligence) is based on performance
attained in reasoning and problem‐solving tasks. Differences in general mental ability have …

Slow-wave activity (SWA), and its coupling with other sleep features, reorganizes cortical
circuitry, supporting cognition. This raises the question: can cognition be improved through …
