Reactivating a Relaxation Exercise During Sleep to Influence Cortical Hyperarousal in Individuals With Frequent Nightmares

Journal of Sleep Research, EarlyView.
ABSTRACT High‐frequency EEG activity during sleep, reflecting cortical hyperarousal, has recently been incorporated into aetiology models of nightmares. However, its precise role remains insufficiently understood because experimental approaches to manipulate hyperarousal during sleep are limited.

Motor Sequence Learning Under Sleep Deprivation

Journal of Sleep Research, EarlyView.
ABSTRACT Sleep deprivation (SD) compromises declarative memory encoding and subsequent consolidation, yet its consequences for the acquisition of new motor skill learning remain unknown. Forty‐eight healthy adults underwent either one night of total SD or normal sleep and were tested the next morning using a multimodal approach combining psychomotor ...

A Double‐Blind Randomised Controlled Crossover Trial of the Effect of Blue‐Enriched Ambient Light on Sleep in Older Adults With Sleep Disturbance: The CleverLights Study

Journal of Sleep Research, EarlyView.
ABSTRACT Light interventions have been investigated for treating sleep disturbances in older adults; however, findings are mixed. This proof‐of‐concept trial investigated the effect of blue‐enriched ambient light on electroencephalographic (EEG) sleep in older adults with self‐reported poor sleep.

Investigating the Link Between Objective Sleep Metrics and Cerebral Small Vessel Disease in a Population‐Based Cohort

Journal of Sleep Research, EarlyView.
ABSTRACT Cerebral small vessel disease (CSVD), a disorder that affects the cerebral microvasculature, is commonly associated with aging and may contribute to dementia and stroke. Increasing evidence suggests a link between CSVD and sleep disturbances, but the association remains poorly understood.
