Abstract Despite decades of research, defining insomnia remains challenging due to its complex and variable nature. Various diagnostic systems emphasize the chronic nature impact on daily functioning, relying heavily patient self-reporting limitations in objective measures such as polysomnography (PSG). Discrepancies between subjective experiences PSG results highlight need for more nuanced approaches, electroencephalogram (EEG) spectral analysis, which reveals distinct patterns high-frequency activity individuals with insomnia. This study explores EEG markers by integrating reports physiological markers, specifically ORP (Odds-Ratio-Product) features, address inconsistencies found previous research clinical settings. Qualitative quantitative definitions are contrasted differences sleep architecture characteristics. The aims determine whether groups defined weekly frequency duration symptoms have different distribution characteristics best distinguish patients from controls. Our findings suggest that ORP, a dependent variable, captures most significant independent variables across model. Elevated beta power indicates increased cortical arousal, supporting perspective hyperarousal disorder. Future should focus using enhance understanding disturbances Comprehensive evaluation requires qualitative, quantitative, neurophysiological data fully understand quality.

Background Increased mortality has been reported in people with insomnia and those obstructive sleep apnoea (OSA). However, these conditions commonly co-occur the combined effect of comorbid (COMISA) on risk is unknown. This study used Sleep Heart Health Study (SHHS) data to assess associations between COMISA all-cause risk. Methods Insomnia was defined as difficulties falling asleep, maintaining and/or early morning awakenings from ≥16 times per month, daytime impairments. OSA an apnoea–hypopnoea index ≥15 events·h −1 . if both were present. Multivariable adjusted Cox proportional hazards models determine association (n=1210) over 15 years follow-up. Results 5236 participants included. 2708 (52%) did not have insomnia/OSA (reference group), 170 (3%) had insomnia-alone, 2221 (42%) OSA-alone 137 COMISA. a higher prevalence hypertension (OR 2.00, 95% CI 1.39–2.90) cardiovascular disease (CVD) 1.70, 1.11–2.61) compared reference group. Insomnia-alone associated but CVD Compared group, 47% (hazard ratio 1.47, 1.06–2.07) increased mortality. The consistent across multiple definitions insomnia. Conclusions rates at baseline, no insomnia/OSA.

Obstructive sleep apnea (OSA) severity can vary markedly from night-to-night. However, the impact of night-to-night variability in OSA on key cardiovascular outcomes such as hypertension is unknown. Thus, primary aim this study to determine effects likelihood. This uses in-home monitoring 15,526 adults with ~180 nights per participant an under-mattress sensor device, plus ~30 repeat blood pressure measures. defined mean estimated apnea-hypopnoea index (AHI) over ~6-month recording period for each participant. Night-to-night determined standard deviation AHI across nights. Uncontrolled systolic ≥140 mmHg and/or diastolic ≥90 mmHg. Regression analyses are performed adjusted age, sex, and body mass index. A total 12,287 participants (12% female) included analyses. Participants highest quartile within category, have a 50-70% increase uncontrolled likelihood versus lowest quartile, independent severity. demonstrates that high predictor hypertension, These findings important implications identification which patients most at risk harm.

Insomnia symptoms and sleep apnea frequently co-occur are associated with worse sleep, daytime function, mental health quality of life, compared to either insomnia or obstructive (OSA) alone. This study aimed investigate the association co-morbid (COMISA) all-cause mortality.Wisconsin Sleep Cohort data were analysed assess potential associations between COMISA mortality. Nocturnal defined as difficulties initiating maintaining and/or early morning awakenings "often" "almost always", regular sedative-hypnotic medicine use. OSA was an apnea-hypopnea index ≥5/hr sleep. Participants classified having neither nor OSA, alone, symptoms. Associations four groups mortality over 20 years follow-up examined via multivariable adjusted Cox regression models.Among 1115 adult participants (mean ± SD age 55 8 years, 53% males), 19.1% had After controlling for sociodemographic behavioral factors, increased risk no (HR [95% CI]; 1.71 [1.00-2.93]). alone (0.91 [0.53, 1.57]) (1.04 [0.55, 1.97]) not risk.Co-morbid is risk. Future research should mechanisms underpinning effectiveness different treatment approaches reduce this common condition.

Sleep is characterized by an intricate variation of brain activity over time. Measuring these temporal sleep dynamics relevant for elucidating healthy and pathological mechanisms. The rapidly increasing possibilities obtaining processing registrations have led to abundance data, which can be challenging analyze interpret. This review provides a structured overview approaches represent dynamics, categorized based on the way source data compressed. For each category representations, we describe advantages disadvantages. Standard human-defined 30-s stages standardization interpretability. Alternative representations are less standardized but offer higher resolution (in case microstructural events such as spindles), or reflect non-categorical information (for example spectral power analysis). Machine-learned additional possibilities: automated useful handling large quantities while alternative obtained from clustering data-driven features could aid finding new patterns possible clinical interpretations. While newly developed may insights, they difficult interpret in context. Therefore, there should always balance between developing sophisticated analysis techniques maintaining explainability.
