0510 Hyperparameter-Tuned Machine Learning Prediction of Obstructive Sleep Apnea and Insomnia from Smartphone App-Derived Sleep Architecture
AbstractIntroductionObstructive sleep apnea (OSA) and insomnia remain widely underdiagnosed. Contactless smartphone applications now provide longitudinal, ecologically valid sleep data at scale. We tested whether machine learning (ML) models train...

0252 Light Exposure Patterns and Sleep/Circadian Timing in Preschool-Aged Children
AbstractIntroductionYoung children (for whom earlier bedtimes are developmentally appropriate) are increasingly exposed to less bright, natural light during the day, and more artificial light at night. This can impact their sleep and overall healt...

0089 Influence of REM Sleep on Working Memory Precision and Capacity
AbstractIntroductionThe rigidity or fluidity of working memory (WM) capacity has been debated, with some studies suggesting that capacity is strictly limited by the number of to-be-remembered objects. While others indicate that prioritizing certai...

1349 REM Predominance on Polysomnography (58.7%)
AbstractIntroductionRapid eye movement (REM) sleep constitutes 20 to 25 percent of total sleep time (TST) in healthy adults. An increase in REM sleep, termed REM rebound or predominance, is typically observed after sleep deprivation, withdrawal of...

0537 Understanding Factors That Influence the Short-Term Reliability of Obstructive Sleep Apnea Symptom Subtypes
AbstractIntroductionMultiple studies from clinical and population samples have established the existence of symptom-based subtypes of OSA. An important step towards clinical translation is understanding factors influencing the short-term reliabili...

0696 Lifestyle Factors in Narcolepsy and Idiopathic Hypersomnia
AbstractIntroductionNarcolepsy and idiopathic hypersomnia (IH) are characterized by excessive daytime sleepiness. They can be caused by deficiency of orexin/hypocretin, a neuropeptide that regulates sleep and wakefulness. It is estimated that 1 in...

0519 Association of Ventilatory and Hypoxic Burden with AI-Derived Obstructive Sleep Apnea Symptoms and Risk Factors
AbstractIntroductionVentilatory Burden (VB) and Hypoxic Burden (HB) have emerged as physiologic metrics that may improve obstructive sleep apnea (OSA) diagnosis and risk stratification beyond the apnea–hypopnea index (AHI). However, the relationsh...
