Cushing's syndrome is associated with an advanced chronotype

Journal of Neuroendocrinology, Volume 38, Issue 10, October 2026.
Abstract Cushing's syndrome is characterised by chronic glucocorticoid excess that abolishes the physiological circadian cortisol rhythm. We investigated whether this circadian disruption alters chronotype. In a single‐centre case–control study, chronotype was assessed using the Munich ChronoType Questionnaire (MCTQ; n = 119) and wrist actigraphy (n ...

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).

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

Journal of Sleep Research, Volume 35, Issue 5, October 2026.
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)
