EEG Brain Rhythms During Resting‐State Wakefulness and Sleep in Elderly Expert Meditators

Journal of Sleep Research, EarlyView.
Compared to controls, elderly expert meditators exhibited (1) more preserved resting‐state brain activity, (2) less altered sleep architecture, and (3) EEG features indicative of heightened cognitive states during NREM sleep. Importantly, several of the metrics that differed between groups also showed consistent correlations with meditation expertise ...

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

Journal of Sleep Research, EarlyView.
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, EarlyView.
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.

Cerebral and Peripheral Hemodynamics Across Wakefulness and NREM Sleep

Journal of Sleep Research, EarlyView.
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‐
