Using at-home intracranial DBS recordings in PD participants, the authors found subcortical beta has an inverse effect on cortical slow-wave in NREM sleep, rises before awakenings and found >88% accuracy in NREM vs Wake classification in brief 5 s epochs.

Microneedle patches that can actively address individual needles are challenging to realize. Here, the authors introduce a spatiotemporal on-demand patch for precise and personalized drug delivery, utilizing electrically triggered control with drug-loaded microneedles and biocompatible metallic membranes.

The authors conducted a comprehensive exome-wide association analysis on eight sleep-related traits. The researchers identified 22 new genes associated with various aspects of sleep, such as chronotype, daytime sleepiness, daytime napping, snoring and sleep apnoea, highlighting the importance of large-scale genomic studies in unravelling the genetic basis of sleep-related traits.

A new study reveals that the disrupted sleep patterns that are frequently observed in patients with cardiac disease are driven by immune-mediated sympathetic denervation and dysfunction of the pineal gland, which leads to a decrease in the circulating levels of melatonin and subsequent sleep disruption.

A novel orexin receptor antagonist improved sleep quality in people with insomnia, without residual effects on daytime functioning.

Biomarkers that predict conversion from isolated REM sleep behaviour disorder to Parkinson disease are urgently needed. A new study finds that detection of misfolded α-synuclein in the cerebrospinal fluid is a good marker of conversion risk, but an inability to predict the timeline of progression might limit its utility.
