Sleep research has evolved considerably since the first sleep electroencephalography recordings in the 1930s and the discovery of well-distinguishable sleep stages in the 1950s. While electrophysiological recordings have been used to describe the sleeping brain in much detail, since the 1990s neu ...

Introduction: Changes in sleep physiology can predate cognitive symptoms by decades in persons with Alzheimer's disease (AD), but it remains unclear which sleep characteristics predict cognitive and neurodegenerative changes after AD onset. Methods: Using data from a prospective cohort of mild to moderate AD (n = 60), we analyzed non-rapid eye moveme ...

Investigating the mechanisms of action of cognitive-behavioural therapy for insomnia (CBT-I), the first-line treatment for chronic insomnia disorder (ID), can contribute to the overall understanding of insomnia and its treatment. To date, no study has examined the relationship between K-complexes ...

Objective: This systematic review and meta-analysis evaluates the efficacy in improving sleep quality and safety of hypnotics in individuals aged 65 years or older compared to those under 65 years. Methods: MEDLINE, EMBASE, Web of Science, and EBM Reviews were searched for randomized clinical trials comparing hypnotics to the placebo in adults with chron ...

Sleep spindles are transient 11-16 Hz brain oscillations generated by thalamocortical circuits. Their role in memory consolidation is well established, but how they play a role in sleep continuity and protection of memory consolidation against interference is unclear. One theory posits that spindles or a neural refractory period following their offset act ...

Objective: National estimates and trends in insomnia symptoms in Canada are outdated. Updates are needed to inform the development of targeted prevention and intervention strategies. This study aimed to examine the prevalence and trends in nighttime insomnia symptoms among Canadians aged 12 years ...

Decrease in cognitive performance after sleep deprivation followed by recovery after sleep suggests its key role, and especially non-rapid eye movement (NREM) sleep, in the maintenance of cognition. It remains unknown whether brain network reorganization in NREM sleep stages N2 and N3 can uniquel ...

Background and aim: Predisposing factors place certain individuals at higher risk for insomnia, especially in the presence of precipitating conditions such as stressful life events. Sleep spindles have been shown to play an important role in the preservation of sleep continuity. Lower spindle den ...

Recent evidence suggests that poor sleep is a potential pathway underlying the association between stressful experiences and the diurnal cortisol profile. However, existing findings are largely limited to adults. The present study examines whether poor sleep (duration, quality) mediates the relation between stressful experiences and the diurnal cortisol p ...
