Exploring the Relationship Between General Motor Activity and Optimal Actigraphy Sleep Configurations: A Systematic Review

Journal of Sleep Research, Volume 35, Issue 2, April 2026.
ABSTRACT This study aimed to determine the optimal configuration of wrist actigraphy for detecting sleep–wake patterns in adults with varying categories of general motor activity (Aim 1), and to assess its validity in relation to polysomnography (Aim 2).

Sleep in Functional Motor Disorders: A Case–Control Polysomnographic Study

Journal of Sleep Research, Volume 35, Issue 2, April 2026.
ABSTRACT Sleep problems are frequent in functional motor disorders (FMDs). Surprisingly, objective correlates of impaired sleep and its relationship to other comorbidities have been understudied, and no polysomnographic study is available. We aimed to map the polysomnographic parameters in the context of self‐reported sleep and mood symptoms and search

Age at Onset and Delays in Diagnosis of Central Disorders of Hypersomnolence Over the Past 30 Years

Journal of Sleep Research, Volume 35, Issue 2, April 2026.
ABSTRACT Patients with narcolepsy type 1 (NT1), type 2 (NT2), idiopathic hypersomnia (IH) usually suffer from symptoms for years, even decades, before being diagnosed. We aimed to assess age at onset, age at diagnosis and changes in the diagnostic delays of these patients from 1990 to 2020 in a single centre.

Sleep and Rhythmic Profile After Pineal Gland Removal in Humans

Journal of Sleep Research, Volume 35, Issue 2, April 2026.
ABSTRACT Melatonin, a hormone produced by the pineal gland, is classically described as a central circadian modulator. However, the impact of its absence on circadian rhythmicity in humans remains poorly understood. Pinealectomised patients, in whom melatonin secretion is chronically suppressed, represent a valuable clinical model to investigate the ...

Evaluating the Effect of a Sleep Prehabilitation Intervention in Patients Awaiting Elective Surgery: Protocol for a Single‐Blind Randomised Trial

Journal of Sleep Research, Volume 35, Issue 2, April 2026.
ABSTRACT Adequate sleep health is critical for surgical recovery. Disrupted sleep can impede wound healing and cognitive performance and contribute to poor surgical outcomes. Preoperative intervention aimed at improving surgical outcomes is often referred to as prehabilitation and commonly uses exercise, nutrition or psychological intervention.

Rest‐Activity Rhythms and Cognition in Older Adults With and Without Insomnia

Journal of Sleep Research, Volume 35, Issue 2, April 2026.
ABSTRACT Insomnia is associated with risk for cognitive deficits. However, the literature assessing cognitive impairments in insomnia is replete with conflicting findings; it is unclear whether individuals with insomnia exhibit impaired cognition or whether specific sleep features consistently predict cognitive performance in insomnia.

Cerebral and Peripheral Hemodynamics Across Wakefulness and NREM Sleep

Journal of Sleep Research, Volume 35, Issue 2, April 2026.
ABSTRACT Wake/sleep‐related changes in cerebral hemodynamic oscillations are well established, but similar changes in peripheral hemodynamics remain largely understudied. Moreover, how the relationship between cerebral and peripheral hemodynamics varies across sleep–wake states is not well understood, despite evidence that these oscillations in the low‐

Health Related Quality of Life and Sleep Regularity Among Middle‐Aged to Older Adults From the Community

Journal of Sleep Research, Volume 35, Issue 2, April 2026.
ABSTRACT Irregular sleep is increasingly related to poorer health, with stronger links to cardiovascular disease and mortality than sleep duration. Its impact on health‐related quality of life, however, remains unclear, particularly in community‐based populations.
