The influence of sleep disruption on learning and memory in fish

Journal of Sleep Research, EarlyView.
Summary Sleep is a ubiquitous process that has been conserved in animals. Yet, our understanding of the functions of sleep largely derives from a few species. Sleep is considered to play an important role in mental processes, including learning and memory consolidation, but how widespread this relationship is across taxa remains unclear.

Actigraphy against 32‐hour polysomnography in patients with suspected idiopathic hypersomnia

Journal of Sleep Research, EarlyView.
Summary Actigraphy, a tool known for investigating sleep–wake patterns at home, lacks scientific validation in hypersomnolent subjects. We aim to validate an actigraphy‐based sleep–wake prediction algorithm against 32‐h continuous polysomnography in patients with suspected idiopathic hypersomnia, and to compare its performance to predict sleep–wake ...

Topological Data Analysis Based Characteristics of Electroencephalogram Signals in Children With Sleep Apnea

Journal of Sleep Research, EarlyView.
ABSTRACT This study aims to identify differences in the functional neural connectivity of the brain of paediatric patients with obstructive sleep apnea. Using EEG signals from 3673 paediatric patients, we grouped subjects into OSA or control groups based on sleep oxygen desaturation levels and apnea‐hypopnea index (AHI), and applied topological data ...

Ikelos‐Rating Scale: Validation of a Behavioural Severity Marker in REM Sleep Behaviour Disorder

Journal of Sleep Research, EarlyView.
ABSTRACT The Ikelos‐Rating Scale (Ikelos‐RS) is a new, expert‐interviewed and bedpartner‐reported severity marker assessing frequency and expression of isolated REM sleep behaviour disorder (iRBD), a precursor of clinical α‐synucleinopathies. This study aimed to validate the Ikelos‐RS in 180 patients with three‐night PSG‐confirmed iRBD (68.4 ± 8.3 ...

Refuting a Temporal Correlation: Interictal Epileptic Discharges Do Not Preferentially Occur During Respiratory Events in Patients With Sleep‐Related Breathing Disorder and Epilepsy

Journal of Sleep Research, EarlyView.
ABSTRACT The bidirectional interaction between sleep and epilepsy is well known. In particular, it has been established that sleep apnea can worsen epilepsy, whereas sleep apnea (SA) treatment has a beneficial effect on seizure control. However, the exact mechanisms whereby SA promotes epileptic seizures are unknown.
