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.

Comparison of Actigraphy and Polysomnography in a Sleep Centre Cohort

Journal of Sleep Research, EarlyView.
MotionWatch 8 actigraphy correlated most strongly with PSG for total sleep time and showed modest group‐level bias, but wide individual limits of agreement precluded interchangeability. PLMS modified actigraphy‐PSG differences, while recording setting influenced actigraphy‐derived sleep continuity across home and inpatient recordings.

Topographical Patterns of Slow Wave Activity in Sleep Talking: An Exploratory Polysomnographic Investigation

Journal of Sleep Research, EarlyView.
ABSTRACT Sleep talking (ST) is a parasomnia characterized by the utterance of unaware linguistic activations during sleep. Electrophysiological evidence is scarce, and it remains unclear whether local electroencephalographic (EEG) alterations characterize the sleep of STs outside of parasomnia episodes. Findings from NREM parasomnias suggest that local

Cerebral blood flow in conscious rats and implications for therapeutic interventions

Experimental Physiology, EarlyView.
Abstract Cerebral blood flow (CBF) often becomes compromised in patients suffering from cardiovascular diseases, increasing the risk of neurodegenerative disease and vascular dementia. There is an urgent need for treatments to address cardiovascular risk without compromising brain perfusion, yet the impact of many existing treatments on CBF are not ...

Longitudinal associations of rapid eye movement (REM) sleep and slow‐wave sleep with plasma Alzheimer's disease biomarkers

Alzheimer's &Dementia, Volume 22, Issue 10, October 2026.
Abstract INTRODUCTION Data on how sleep architecture relates to progression of plasma Alzheimer's disease biomarkers remains limited. METHODS Sixty‐four cognitively unimpaired older adults (ages 55–90) underwent plasma collection twice 2.6 years apart and polysomnography proximate to the first plasma collection.

Identifying High‐Risk Children Safe for Same‐Day Discharge After Tonsillectomy

The Laryngoscope, Volume 136, Issue 10, Page 4497-4504, October 2026.
ABSTRACT Objective Current guidelines recommend overnight admission for children with severe obstructive sleep apnea (OSA) and obesity undergoing tonsillectomy, although most have uneventful postoperative courses. We aimed to identify low‐risk subgroups within this high‐risk population who may be candidates for same‐day discharge. Methods Retrospective

An electroencephalographic fingerprint of NREM sleep

, 2004
The existence of homeostatic and circadian processes regulating human sleep seems to challenge the common notion of individual variations in sleep need or differences in circadian types.

Critically Ill Children Show Disrupted Sleep Patterns and Atypical Electroencephalograms: An Observational Cohort Study

Acta Paediatrica, Volume 115, Issue 10, Page 2323-2331, October 2026.
ABSTRACT Aim Sleep disruptions are common in hospitalised children. This study described sleep in critically ill and non‐critically ill hospitalised children, including young infants and patients with central nervous system injuries. Methods This observational cohort study included two groups: critically ill children admitted to a paediatric intensive ...

Continuous Versus Routine EEG in Critically Ill Patients Without Primary Neurologic Condition: Analysis of a Randomized Controlled Trial

European Journal of Neurology, Volume 33, Issue 10, October 2026.
ABSTRACTIntroductionContinuous EEG (cEEG) is increasingly used in critically ill patients, driven by its superior seizure detection sensitivity over routine EEG (rEEG). However, cEEG is resource‐demanding, and whether its use translates into improved clinical outcomes in patients without primary neurologic conditions remains unknown.MethodsThis is a ...

Phenotypic Variability in Slow‐Wave Sleep in Depression: Associations With Clinical Profiles and Disorder Severity

Journal of Sleep Research, Volume 35, Issue 5, October 2026.
ABSTRACT Slow‐wave sleep (SWS; stage N3) is often reported as reduced in depression, yet variability across depressive phenotypes remains poorly characterised. This study aimed to determine whether N3 architecture—proportion, duration, and latency—identifies clinically distinct profiles in major depressive episode (MDE).
