“…These contrast to other studies where self-reported sleep was evaluated in older adults with measures of global cognition (i.e., mini-mental score), which may be insensitive to cognitive variability. 2,6 We observed an interaction between sleep duration and sex. Stratified analysis indicated that the association between sleep duration and cognitive function differed between males and females.…”

“…25 In contrast, HCHS/ SOL participants with longer sleep durations had markedly lower neurocognitive scores, consistent with evidence from cross-sectional and longitudinal studies suggesting that long sleep predicts impaired neurocognitive function and dementia in older adults. 4,[6][7][8] In our study, the association between sleep duration and neurocognitive function was seen across all cognitive tests, except for delayed memory. In a cohort of older men, disturbed sleep was associated primarily with decline in executive function, but not with global cognition.…”

“…2,3 Existing research on sleep duration and neurocognitive function mainly involved older or non-Hispanic white cohorts, which limits generalizability to middle-aged and non-white populations. [4][5][6] A few studies have observed associations between long sleep duration and cognitive function, but these studies are mostly from older cohorts that contain relatively small samples of Hispanic/Latinos and only included measures of global cognition such as the mini-mental examination. [4][5][6] In addition, most studies have not accounted for daytime sleepiness, use of sleep medication, and sleep apnea, which are possible confounders between sleep duration and neurocognitive function.…”

Study Objectives: To evaluate the association between sleep duration and neurocognitive function in a representative sample of middle-aged to older Hispanic/Latino adults in the US. We tested the hypothesis that sleep duration has a nonlinear, inverted U-shaped association with neurocognitive function. Methods: We performed a cross-sectional analysis from the Hispanic Community Health Study/Study of Latinos (HCHS/SOL) participants ages 45-74 years (n = 8,676). HCHS/SOL is a community-based cohort from four US urban areas sampled using a probability design from 2008-2011. Self-reported sleep duration was calculated as a weighted average of the difference between habitual wake and bedtimes assessed by separate questions for weekdays and weekends. Neurocognitive function was measured with standardized scores for Word (Phonemic) Fluency (WF), Brief-Spanish English Verbal learning test (B-SEVLT), and Digit Symbol Substitution (DSS) tests. Results: The mean age was 56.5 years; 55% were women; and 40.4% had less than high school education. Average sleep duration was 7.8 ± 1.7 hours. There was an inverted U-shaped association with sleep duration and WF, B-SEVLT sum, and the DSS, with no association with B-SEVLT delayed-recall. Participants with intermediate sleep duration had the best neurocognitive function, while long sleepers had worse neurocognitive function adjusting for demographic, behavioral, and medical factors, daytime sleepiness, and use of sleep medications. Conclusions: Sleep duration had curvilinear inverted U-shaped associations with neurocognitive function, with worse scores among participants with longer sleep duration. These findings may provide a framework to further examine sleep duration in the prevention and treatment of neurocognitive disorders.

“…[5][6][7][8] However, data are sparse on sleep and cognitive function in multiethnic populations. In the Northern Manhattan Study (NOMAS), sleep disturbances are associated with worse cognitive performance in the Mini-Mental State Examination score and subclinical markers of vascular disease, [9][10][11] known contributors to cognitive decline and dementia. 12 It is unclear if specific cognitive domains are specifically affected by these sleep disturbances, accounting for confounders such as vascular risk factors, which have strong associations with poor sleep.…”

Objective: To examine frequent snoring, sleepiness, and sleep duration with baseline and longitudinal performance on neuropsychological (NP) battery. Methods:The analysis consists of 711 participants of the Northern Manhattan Study (NOMAS) with sleep data and NP assessment (age 63 6 8 years, 62% women, 18% white, 17% black, 67% Hispanic) and 687 with repeat NP testing (at a mean of 6 6 2 years). The main exposures were snoring, sleepiness, and sleep duration obtained during annual follow-up. Using factor analysis-derived domain-specific Z scores for episodic memory, language, executive function, and processing speed, we constructed multivariable regression models to evaluate sleep symptoms with baseline NP performance and change in performance in each NP domain.

Objective This study aimed to examine the association between self-reported sleep problems and cognitive decline in community-dwelling older people. We hypothesized that daytime somnolence predicts subsequent cognitive decline. Methods This is a longitudinal study in a 3.2-year follow-up, with 18-month intervals. The setting is the Washington Heights-Inwood Community Aging Project. There were 1098 participants, who were over 65 years old and recruited from the community. Sleep problems were estimated using five sleep categories derived from the RAND Medical Outcome Study Sleep Scale: sleep disturbance, snoring, awaken short of breath/with a headache, sleep adequacy, and daytime somnolence. Four distinct cognitive composite scores were calculated: memory, language, speed of processing, and executive functioning. We used generalized estimating equations analyses with cognitive scores as the outcome, and time, sleep categories and their interactions as the main predictors. Models were initially unadjusted and then adjusted for age, gender, education, ethnicity, depression, and apolipoprotein E-ε4 genotype. Results Increased daytime somnolence (including feeling drowsy/sleepy, having trouble staying awake, and taking naps during the day) was linked to slower speed of processing both cross-sectionally (B = −0.143, p = 0.047) and longitudinally (B = −0.003, p = 0.027). After excluding the demented participants at baseline, the results remained significant (B = −0.003, p = 0.021). Conclusions Our findings suggest that daytime somnolence may be an early sign of cognitive decline in the older population. Copyright # 2015 John Wiley & Sons, Ltd.
