Hypoxic Load and Average Oxygen‐Saturation During Sleep and Wake Are Associated With Cognitive Function in Obstructive Sleep Apnea

Journal of Sleep Research, EarlyView.
ABSTRACT Cognitive processes commonly affected by obstructive sleep apnea (OSA) are more strongly associated with hypoxic load parameters than the apnea‐hypopnea index (AHI). Additionally, lower SpO2 during wake affects cognition, emphasising the need for concurrent assessment with sleep SpO2.

Predicting Sleep and Sleep Stage in Children Using Actigraphy and Heartrate via a Long Short‐Term Memory Deep Learning Algorithm: A Performance Evaluation

Journal of Sleep Research, EarlyView.
ABSTRACT Children's ambulatory sleep is commonly measured via actigraphy. However, traditional actigraphy measured sleep (e.g., Sadeh algorithm) struggles to predict wake (i.e., specificity, values typically < 70) and cannot predict sleep stages. Long short‐term memory (LSTM) is a machine learning algorithm that may address these deficiencies.

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

Hybrid System for Engagement Recognition During Cognitive Tasks Using a CFS + KNN Algorithm

Sensors, 2018
Engagement is described as a state in which an individual involved in an activity can ignore other influences. The engagement level is important to obtaining good performance especially under study conditions. Numerous methods using electroencephalograph

Human brain imaging with high‐density electroencephalography: Techniques and applications

The Journal of Physiology, EarlyView.
Abstract figure legend Recent technological advances have elevated high‐density electroencephalography (hdEEG) to the status of a reliable neuroimaging tool. This technique measures scalp potentials with high temporal resolution, which permits the non‐invasive detection and analysis of neural oscillations.

BMI, Sleep Architecture, and Glucose Metabolism: Insights From the Baependi Heart Study

Obesity, Volume 33, Issue 10, Page 1849-1854, October 2025.
ABSTRACT Objective To examine whether (1) sleep architecture is associated with BMI groups in the absence of sleep apnea and (2) BMI group modified associations between sleep architecture and markers of glucose metabolism. Methods The Baependi Heart Study (BHS) is a family‐based observational study of adults that assessed sleep using at‐home ...
