Abstract Study Objectives: To investigate the contribution of sleep duration and quality to
age-related changes in brain structure and cognitive performance in relatively healthy older …

Abstract Study Objectives: To determine the association between self-reported sleep
duration and cortical thinning among older adults. Methods: We studied 122 cognitively …

Context: Increasing evidence suggests that circadian and sleep parameters influence
cognitive function with aging. Objective: To evaluate observational studies of sleep duration …

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 …

Objective Sleep is important for brain health. We analysed associations between usual
sleep habits and magnetic resonance imaging (MRI) markers of neurodegeneration (brain …

Alterations in sleep patterns are common among older adults; further, short and long sleep
durations have been linked with impaired cognitive performance in older individuals. Yet …

Background: Alterations in sleep architecture are common among older adults. Previous
studies have documented associations between sleep duration, sleep quality, and cognitive …

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 …

Abstract Study Objectives: To investigate the association between sleep-related
characteristics and cognitive change over 3 years of follow up in an aged population …

Abstract Study Objectives This study aims to evaluate the extent to which sleep quality
impacts amnestic mild cognitive impairment (aMCI)-related brain regions in a cognitively …
