Bidirectional temporal associations between sleep and affect and cognitive symptoms among community-dwelling stroke survivors: An ecological momentary assessment study.

Introduction: Sleep plays a critical role in daily functioning and stroke recovery but receives little attention in stroke rehabilitation. Sleep disturbances are linked to affective and cognitive impairments, but temporal associations between sleep and affect and cognitive symptoms are less clear. Understanding these temporal associations may inform new directions in intervention and prevention to support continued stroke recovery.

Relationships between the Pittsburgh Sleep Quality Index (PSQI), Epworth Sleepiness Scale (ESS), and clinical/polysomnographic measures in a community sample.

Study Objectives: 1) To characterize PSQI and ESS scores, and their relationship to each other, in an adult community sample; 2) To determine whether PSQI and ESS scores, in combination with each other, were associated with distinct demographic, clinical, and sleep characteristics.

Methods: The PSQI, ESS, clinical rating scales, sleep diaries, actigraphy, and home polysomnography were collected from 187 community-dwelling adults (mean age 59.5 years, 47.

EEG spectral analysis in primary insomnia: NREM period effects and sex differences.

Study Objectives: To compare NREM EEG power in primary insomnia (PI) and good sleeper controls (GSC), examining both sex and NREM period effects; to examine relationships between EEG power, clinical characteristics, and self-reports of sleep.

Design: Overnight polysomnographic study.

Setting: Sleep laboratory.
