iSPHYNCS: Unsupervised Clustering in Questionnaires and Metadata Reveals Distinct Subtypes in the Narcolepsy Borderland

open access: yesJournal of Sleep Research, EarlyView.
Study overview and clustering results in the iSPHYNCS cohort. Participant demographics are summarized in a baseline table. Questionnaire data and metadata were processed through an unsupervised clustering pipeline. A Sankey plot illustrates individual assignment across clusters by diagnostic group.

Quantifying Cortical Maturational Aspects During Different Vigilance States in Preterm Infants by Advanced EEG Analysis

open access: yesJournal of Sleep Research, EarlyView.
ABSTRACT Preterm birth is a significant risk factor for atypical neurodevelopment, yet early electrophysiological markers of brain maturation are still lacking. Non‐invasive electroencephalographic (EEG) monitoring of cortical maturation in these patients holds promise as a tool for neurodevelopmental prediction.

No Evidence for Seasonal Variations in Fatigue, Sleepiness and Insomnia Symptoms: Spring Fatigue Is a Cultural Phenomenon Rather Than a Seasonal Syndrome

open access: yesJournal of Sleep Research, EarlyView.
ABSTRACT Although not as prominent as in other animals, humans also experience seasonal variations in sleep duration and circadian processes. These variations are likely primarily driven by changes in photoperiod length. Anecdotally, many people report experiencing fatigue and low energy levels, particularly during spring in Germany, Switzerland and ...

Nocturnal Sleep Breathing Patterns in Healthy Adolescents Residing at Very High Altitudes in Bolivia

open access: yesJournal of Sleep Research, EarlyView.
ABSTRACT Data on sleep and respiratory patterns among adolescents residing at very high altitude (> 3500 m) remain scarce, and altitude‐related physiological differences may influence these parameters. Studying adolescents at different very high altitudes is crucial, as subtle environmental variations could affect sleep‐related oxygenation and ...

Investigation of the “Not Better Explained” Diagnosis Criteria in Sleep Disorder Classifications: A Systematic Content Analysis and Critical Review

open access: yesJournal of Sleep Research, EarlyView.
The “Not Better Explained” (NBE) criterion plays a key role in preventing diagnostic misclassification by structuring causal reasoning in sleep medicine. This systematic content analysis compares the use, wording, and excluded conditions of NBE criteria across the ICSD‐3‐TR and DSM‐5‐TR for ten major sleep disorders.

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

open access: yesJournal of Sleep Research, EarlyView.
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).

Peripheral Inflammation and Sleep Loss Induce Coordinated Motivational Changes: An Experimental Two‐Hit Stress Model

open access: yesJournal of Sleep Research, EarlyView.
ABSTRACT Sleep loss and low‐grade inflammation are common stressors that affect behaviour and recovery needs. To examine their separate and combined effects on motivation for everyday behaviours, we developed a two‐hit experimental model. Participants (N = 56, 31 women) completed three experimental visits: sleep saturation (two nights, 9 h in bed/night)

The Pharyngeal Resistance Index—A Promising Diagnostic Tool in OSA

open access: yesJournal of Sleep Research, EarlyView.
ABSTRACT This study investigates the newly developed pharyngeal resistance index derived from computational fluid dynamics analysis of the upper airway in patients with obstructive sleep apnea. The aim was to evaluate this index as a diagnostic and severity assessment tool by comparing it with the apnea‐hypopnea index before and after maxillomandibular

Persistent Sleep Disturbance Following Pandemic Lockdowns: Longitudinal Findings From the UK COVID‐19 Symptom Study Biobank

open access: yesJournal of Sleep Research, EarlyView.
ABSTRACT Sleep disturbance and fatigue were highly prevalent during the COVID‐19 pandemic, in both infected and non‐infected individuals, though mostly assessed cross‐sectionally. To assess these symptoms after lockdown cessation, we conducted a prospective longitudinal study in a large UK cohort.
