Sleep Stage Classification by a Combination of Actigraphic and Heart Rate Signals

Journal of Low Power Electronics and Applications, 2017
Although heart rate variability and actigraphic data have been used for sleep-wake or sleep stage classifications, there are few studies on the combined use of them. Recent wearable sensors, however, equip both pulse wave and actigraphic sensors.

Mechanisms of parasite‐mediated disruption of brain vessels

FEBS Letters, EarlyView.
Parasites can affect the blood vessels of the brain, often causing serious neurological problems. This review explains how different parasites interact with and disrupt these vessels, what this means for brain health, and why these processes matter. Understanding these mechanisms may help us develop better ways to prevent or treat brain infections in ...

Assessment of continuous positive airway pressure effect on the circadian clock signaling pathway in obstructive sleep apnea patients

Scientific Reports
Obstructive sleep apnea (OSA) is associated with circadian rhythm dysregulation plausibly through affecting clock genes. The study’s purpose was to investigate the effect of one-night continuous positive airway pressure treatment (CPAP treatment) on ...

Time after time – circadian clocks through the lens of oscillator theory

FEBS Letters, EarlyView.
Oscillator theory bridges physics and circadian biology. Damped oscillators require external drivers, while limit cycles emerge from delayed feedback and nonlinearities. Coupling enables tissue‐level coherence, and entrainment aligns internal clocks with environmental cues.

Exploring differences in signaling pathways of the circadian clock and neuromodulators in obstructive sleep apnea

Scientific Reports
Obstructive sleep apnea (OSA) is a prevalent disorder characterized by recurring upper airway obstructions, leading to disrupted sleep and systemic complications. The complexity of OSA suggests intricate interactions between neuromodulators and circadian

Vestibular Evoked Myogenic Potentials Are Abnormal in Idiopathic REM Sleep Behavior Disorder

Frontiers in Neurology, 2018
Objectives: To investigate brainstem function in idiopathic REM sleep Behavior Disorder (iRBD), a condition occurring as a result of a derangement of connections within brainstem structures, with a battery of Vestibular Evoked Myogenic Potentials (VEMPs),

Prevalence of sleep disorder diagnoses and sleep medication prescriptions in individuals with ADHD across the lifespan: a Swedish nationwide register-based study

BMJ Mental Health, 2023
Background Consistent evidence suggests a strong association between attention-deficit/hyperactivity disorder (ADHD) and subjectively reported sleep problems. However, the prevalence of clinically ascertained sleep disorder diagnoses and sleep medication

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

Molecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

CHILDHOOD SLEEP DISORDERS [PDF]

Neurologic Clinics, 1996
Sleep problems in children may differ in various ways from analogous problems in the adult. This is less because of neurophysiologic differences between the two groups than it is because of the child's greater level of dependency. Young children make few decisions on their own and, as a result, parent-child interactions become connected intimately to ...
