Postmortem Evidence of CRH Neuron Reduction in Narcolepsy Without Cataplexy With Borderline Hypocretin‐1 Levels

Journal of Sleep Research, Volume 35, Issue 5, October 2026.
ABSTRACT Narcolepsy is classified as type 1 (NT1) or type 2 (NT2) mainly according to hypocretin deficiency rather than cataplexy. While CRH neuron loss in the PVN has been described in NT1, it remains unclear whether similar changes occur in narcolepsy without cataplexy.

Differences in Sleep Spindle Characteristics Between Children With Narcolepsy and Those With Other Causes of Subjective Sleepiness

Journal of Sleep Research, Volume 35, Issue 5, October 2026.
ABSTRACT Central disorders of hypersomnolence are characterised by excessive daytime sleepiness. There has been growing interest in analysing sleep micro‐architecture, to further understand how sleep is affected by these conditions. We investigated if sleep spindle activity differed between children with narcolepsy, idiopathic hypersomnolence (IH) and ...

Distinct EEG Features and Sleep/Wake Behaviour Predict Anxiety Phenotypes in Mice

Journal of Sleep Research, Volume 35, Issue 5, October 2026.
ABSTRACT Preoperative anxiety is a prevalent clinical problem linked to adverse surgical outcomes, including elevated pain, prolonged hospital stays and increased risk of postoperative delirium. Current assessments rely heavily on subjective measures, necessitating objective biomarkers.

Time–frequency characteristics of scalp high‐frequency oscillations provide complementary biomarkers in infantile epileptic spasms syndrome

Experimental Physiology, Volume 111, Issue 10, Page 4852-4875, 1 October 2026.
Abstract Infantile epileptic spasms syndrome (IESS) is characterized by epileptic spasms (ES) in infants and hypsarrhythmia on EEG. High‐frequency oscillations (HFOs), defined as oscillatory events at >80 Hz, reflect rapid spatiotemporal dynamics of cortical activity and might serve as novel biomarkers for epilepsy.
