Depressive symptoms in patients with hypersomnia measured with Beck Depression Inventory.

BACKGROUND: Patients with central hypersomnia (HCO) often show symptoms of depression. Despite of many studies conducted in this field, the link between these two disorders remains unclear. In order to contribute data to this research, we examined the question of which depressive symptoms characterize these patients. Furthermore, we investigated the differences between HCO who were more or less depressed regarding insomnia, sleep quality and daytime tiredness. METHODS AND MATERIAL: The retrospective analysis assesses the presence and kind of depressive symptoms as measured by the Beck Depression Inventory (BDI) in 168 HCO including narcolepsy type I (NAR1), narcolepsy type II (NAR2) and idiopathic hypersomnia (HYP). Sleep parameters from one night of polysomnography, scores of questionnaires for insomnia and for daytime sleepiness, and data from sustained attention tests were compared between HCO with and without depression, as determined by BDI scores (cut off >12). RESULTS: According to BDI scores 52% exhibited no depression. The BDI items pertaining to tiredness and work inhibition exhibited elevated scores, whereas those pertaining to suicidality showed low scores. No difference was found between depressed and non-depressed HCO with regard to daytime vigilance performance or daytime sleepiness. However, depression was associated with older age, higher insomnia scores, and a shorter sleep time on polysomnography. CONCLUSION: A potential interpretation of our findings is that depressive symptoms in HCO may be a consequence of restricted life quality due to hypersomnia. Thus, therapeutical effort should focus more intensely on coping strategies.

The mediating roles of psychological resilience and psychological well-being of caregivers for the older adults.

Objective: This study aimed to investigate the mediating effects of psychological resilience and psychological well-being for caregivers at nursing homes on the relationship between insomnia and elder maltreatment. As the world is aging quickly and the number of older individuals cared for by formal caregivers has been increasing, this study's results could help create intervention programs to minimize the occurrence of older people's maltreatment. Materials and Methods: A total of 431 care workers who met all criteria, from 21 care service centers for older adults in Fukuoka, Japan, completed the Conditions of Maltreatment Scale, Caregivers' Belief in Ideal Care, Insomnia Severity Index, WHO-5 Well-Being Index, and Connor-Davidson Resilience Scale-10. Results: A multivariate analysis of variance revealed that participants with no insomnia had greater resilience, higher psychological well-being, and greater belief in ideal care and to treated older clients less roughly compared to participants with insomnia. Psychological resilience and well-being were significant mediators in the relationship between insomnia, rough care, and beliefs in ideal care. Conclusion: As formal caregivers are in urgent demand, society should take care of them. The most effective and successful intervention for improving their physical and psychological well-being should be initiated at the individual and organizational levels.

Sleepless in the Pursuit of perfection: A longitudinal investigation of bidirectional relationships between insomnia and perfectionism in Adolescent males and females.

STUDY OBJECTIVES: Perfectionism is a possible risk factor for insomnia, yet longitudinal evidence of this relationship in adolescence is lacking. Cross-sectional evidence suggests the nature of the relationship may differ based on biological sex, and the form of perfectionism, since socially prescribed and self-oriented critical perfectionism are conceptualised as maladaptive for wellbeing, while self-oriented striving may be adaptive or neutral. This study aimed to investigate longitudinal bidirectional relationships between total perfectionism, and sub-forms of perfectionism (i.e., socially prescribed, self-oriented critical, self-oriented striving perfectionism), and symptoms of insomnia, over the course of mid-adolescence. Longitudinal models were examined for males and females separately. METHODS: 434 adolescents (Mage = 14.25, SD = 0.56, range = 13-16, 52 % male) completed questionnaire measures of perfectionism (Child-Adolescent Perfectionism Scale) and insomnia (Insomnia Severity Index) on three annual occasions (at approximately 14, 15 & 16 years of age). Data were from the larger Risks to Adolescent Wellbeing (RAW) Project. RESULTS: Biological sex did not moderate the association between insomnia symptoms and any form of perfectionism. Cross-lagged panel models showed no longitudinal relationship between self-oriented striving, nor self-oriented critical perfectionism and insomnia symptoms for males or females. Higher total perfectionism predicted moderate increases in insomnia symptoms for males and females, but insomnia symptoms did not predict changes in total perfectionism. Socially prescribed perfectionism and insomnia symptoms predicted large and moderate increases in one another over time, respectively, forming a perpetuating cycle. CONCLUSIONS: Results suggest that perfectionism may be an important risk factor for insomnia symptoms in adolescents.

Protocol of a randomized controlled trial into guided internet-delivered cognitive behavioral therapy for insomnia in autistic adults (i-Sleep Autism).

BACKGROUND: Sleep problems, especially insomnia, are prevalent among autistic adults, affecting about 60 %, and significantly impact their quality of life. Internet-based cognitive behavioral therapy for insomnia (iCBT-I) could provide accessible and scalable treatment. Given the unique sensory- and information processing, and social challenges at play in autism, a tailored treatment approach may be essential to tackle sleep problems. Yet, interventions developed and tested specifically for autistic adults were scarce. Addressing this gap is crucial to meet the urgent need for effective insomnia treatments in this population. METHODS: With this two-arm, parallel, superiority randomized controlled trial, we will assess the effectiveness of a guided iCBT-I intervention for adults (N = 160) with autism and insomnia (i-Sleep Autism). In co-creation, i-Sleep Autism has been adjusted from an existing intervention (i-Sleep). Inclusion criteria are: age ≥ 18, an ASD diagnosis, and at least sub-threshold insomnia (Insomnia Severity Index ≥10). Participants are randomly assigned to either i-Sleep Autism or an information only waitlist control condition (online psychoeducation and sleep hygiene). After 6 weeks, the control group receives the intervention. Insomnia severity is the primary outcome. Secondary outcomes include pre-sleep arousal, general mental health, depression, anxiety, daily functioning, and quality of life. Assessments will occur at baseline, mid-intervention (3 weeks), post-intervention (6 weeks), and at 6-month follow-up (the intervention group). Linear mixed-effect regression models are employed to evaluate the effectiveness of i-Sleep Autism, alongside exploration of potential moderators and mediators. CONCLUSION: This trial can reveal whether autistic adults with insomnia benefit from a guided e-health intervention. TRIAL REGISTRATION: NL-OMON56692.

Promoting sustained access to cognitive behavioral therapy for insomnia in Australia: a system-level implementation program.

STUDY OBJECTIVES: Insomnia is a highly prevalent and debilitating disorder. Cognitive behavioral therapy for insomnia (CBTi) is the recommended 'fist line' treatment, but is accessed by a minority of people with insomnia. This paper describes a system-level implementation program to improve access to CBTi in Australia to inform CBTi implementation in other locations. METHODS: From 2019 to 2023, we conducted a program of work to promote sustained change in access to CBTi in Australia. Three distinct phases included 1) Scoping and mapping barriers to CBTi access, 2) Analysis and synthesis of barriers and facilitators to devise change goals, and 3) Structured promotion and coordination of change. We used a system-level approach, knowledge brokerage, and co-design, and drew on qualitative, quantitative, and implementation science methods. RESULTS: We identified barriers to CBTi access from the perspectives of people with insomnia, primary care clinicians, and the health system. A stakeholder advisory committee was convened to co-design change goals, identify modifiable barriers, devise program logic and drive change strategies. We commenced a program to promote system-level change in CBTi access via; improved awareness and education of insomnia among primary care clinicians, self-guided interventions, and advocating to Government for additional CBTi funding mechanisms. CONCLUSIONS: This implementation program made significant progress toward improving access to CBTi in Australia. Ongoing work is required to continue this program, as long-term system-level change requires significant and sustained time, effort and resources from multiple stakeholders. This program may be used to inform CBTi implementation activities in other locations.

Treatment of Depression-Related Circadian Rhythm Sleep-Wake Disorder (CRSWD) With Melatonin Receptor Agonist Ramelteon: A Case Report.

Insomnia, also called sleeplessness, is a sleep disorder with very diverse sleep problems and is classified into seven categories. Circadian rhythm sleep-wake disorder (CRSWD) is a type of insomnia characterized by the misalignment of the body's circadian clock with the external 24-hour environmental cycle. CRSWD encompasses seven subtypes, among which delayed sleep-wake phase disorder (DSWPD) is prominently recognized for its impact on sleep patterns. Sleep disturbances, particularly insomnia, are prevalent in depressed patients, often serving as a primary symptom that prompts clinical consultation. CRSWD frequently leads to significant social dysfunction, often making it impossible for students to attend school and difficult for working adults to find employment. Effective treatments for CRSWD include bright light therapy, cognitive-behavioral therapy for insomnia (CBT-I), and melatonin receptor agonists, particularly for certain CRSWD subtypes. In this case report, the melatonin receptor agonist ramelteon was administered to a high school student with DSWPD and comorbid depression, resulting in the successful management of symptoms. Following treatment, the patient resumed high school, pursued a university education, and secured employment post-graduation. These findings indicate that ramelteon may be a promising treatment option for CRSWD in patients with comorbid depression, warranting further clinical investigation.

Screening for Psychiatric Disorders in Chronic Rhinosinusitis Patients Waiting for Surgery: A Prospective Cross-Sectional Study.

OBJECTIVE: To assess the prevalence of depression, anxiety, insomnia and somatic symptom disorder (SSD) in chronic rhinosinusitis (CRS) patients who were waiting for surgery and to predict these psychiatric disorders using the 22-item Sinonasal Outcome Test (SNOT-22). DESIGN: A prospective cross-sectional study. SETTING: The rhinology ward at our institution, a tertiary hospital. PARTICIPANTS: Adult patients (> 18 years) diagnosed with CRS who were admitted to the rhinology ward for endoscopic sinus surgery and were able to understand and complete the study questionnaires. MAIN OUTCOME MEASURES: Patient Health Questionnaire-9 (PHQ-9), Generalised Anxiety Disorder-7 (GAD-7), Insomnia Severity Index (ISI), Patient Health Questionnaire-15 (PHQ-15) and SNOT-22. RESULTS: Of the 159 participants recruited, 58 were at risk of depression (defined by PHQ-9 > 4, while 25 with PHQ-9 > 9), 49 were at risk of anxiety (defined by GAD-7 > 4, while 25 with GAD-7 > 9), 81 were at risk of insomnia (defined by ISI > 7, while 51 with ISI > 14) and 69 were at risk of SSD (defined by PHQ-15 > 4, while 24 with PHQ-15 > 9). The SNOT-22 score was closely correlated with the scores of psychometric tests and was an independent predictor of these psychiatric disorders. Patients with a high SNOT-22 score (> 30) are likely to be affected by comorbid psychiatric disorders and should be further evaluated by otolaryngologists. CONCLUSION: Depression, anxiety, insomnia and SSD are prevalent in CRS patients. Otolaryngologists should have a low threshold to ask the patient about psychiatric symptoms, especially for patients with an SNOT-22 score > 30.

The Relationship Between Epidemic Perception and Cyberbullying Behaviors of Chinese Adolescents During the COVID-19 Pandemic: Cross-Sectional Study.

Background: In response to the COVID-19 outbreak, the government initiated measures for social distancing, leading to a gradual transition of adolescents' social interactions toward web-based platforms. Consequently, web-based behaviors, particularly cyberbullying, have become a prominent concern. Considering that adolescents experience more intense feelings, the widely increased negative emotions and strains perceived from the COVID-19 pandemic may end up engaging in cyberbullying behaviors. In addition, during the COVID-19 pandemic, adolescents experiencing insomnia and negative affect are more prone to diminished self-control, which is associated with cyberbullying behaviors. Objective: This study aims to investigate the relationship between epidemic perception and cyberbullying behaviors, while also examining the serial mediating roles of insomnia and negative affect on the relationship between epidemic perception and cyberbullying behaviors. Methods: This study presents a large-scale web-based survey conducted during the period of concentrated COVID-19 outbreaks, encompassing 20,000 Chinese adolescents. A total of 274 submitted questionnaires were discarded because of high levels of missing data or their answers were clearly fictitious or inconsistent. The final count of valid participants amounted to 19,726 (10,371 boys, age range: 12-18 years; mean 14.80, SD 1.63 years). The Perceptions of COVID-19 Scale, Negative Affect Scale, Insomnia Scale, and Cyberbullying Behavior Scale were used to assess participants' responses on the Questionnaire Star platform. Results: The results show that epidemic perception is positively correlated with cyberbullying behaviors (r=0.13; P<.001), insomnia (r=0.19; P<.001), and negative affect (r=0.25; P<.001). Insomnia is positively correlated with negative affect (r=0.44; P<.001) and cyberbullying behaviors (r=0.30; P<.001). Negative affect is positively correlated with cyberbullying behaviors (r=0.25; P<.001). And insomnia and negative affect play independent mediating and serial mediating roles in epidemic perception and cyberbullying behaviors. Conclusions: This study provides additional empirical evidence on the relationship between the perception of COVID-19 pandemic and cyberbullying in adolescents. In addition, the study offers recommendations for implementing interventions targeted at mitigating cyberbullying in adolescents during the COVID-19 pandemic.

Can Neuromodulation Improve Sleep and Psychiatric Symptoms?

PURPOSE OF REVIEW: In this review, we evaluate recent studies that employ neuromodulation, in the form of non-invasive brain stimulation, to improve sleep in both healthy participants, and patients with psychiatric disorders. We review studies using transcranial electrical stimulation, transcranial magnetic stimulation, and closed-loop auditory stimulation, and consider both subjective and objective measures of sleep improvement. RECENT FINDINGS: Neuromodulation can alter neuronal activity underlying sleep. However, few studies utilizing neuromodulation report improvements in objective measures of sleep. Enhancements in subjective measures of sleep quality are replicable, however, many studies conducted in this field suffer from methodological limitations, and the placebo effect is robust. Currently, evidence that neuromodulation can effectively enhance sleep is lacking. For the field to advance, methodological issues must be resolved, and the full range of objective measures of sleep architecture, alongside subjective measures of sleep quality, must be reported. Additionally, validation of effective modulation of neuronal activity should be done with neuroimaging.

Exploring the pathogenesis of insomnia and acupuncture intervention strategies based on the microbiota-gut-brain axis.

Insomnia is a common sleep disorder observed in clinical settings, with a globally rising prevalence rate. It not only impairs sleep quality and daytime functioning but also contributes to a range of physiological and psychological conditions, often co-occurring with somatic and mental disorders. Currently, the pathophysiology of this condition is not fully understood. Treatment primarily involves symptomatic management with benzodiazepine receptor agonists, melatonin and its receptor agonists, sedative antidepressants, atypical antipsychotics, and orexin receptor antagonists. However, due to the adverse side effects of these drugs, including dependency, addiction, and tolerance, there is an urgent need for safer, more effective, and environmentally friendly treatment methods. In recent years, research on the microbiota-gut-brain axis has received significant attention and is expected to be key in uncovering the pathogenesis of insomnia. Acupuncture stimulates acupoints, activating the body's intrinsic regulatory abilities and exerting multi-pathway, multi-target regulatory effects. A substantial body of evidence-based research indicates that acupuncture is effective in treating insomnia. However, the unclear mechanisms of its action have limited its further clinical application in insomnia treatment. Therefore, this study aims to elucidate the pathogenesis of insomnia from the perspective of the microbiota-gut-brain axis by examining metabolic, neuro-endocrine, autonomic nervous, and immune pathways. Additionally, this study discusses the comprehensive application of acupuncture in treating insomnia, aiming to provide new strategies for its treatment.

Sex differences in insomnia and hypersomnia complaints during major depressive episode: Results from a national sample.

BACKGROUND: Sex differences in sleep disturbances during major depressive episodes (MDE) have been suggested. This study compares the prevalence, sociodemographic characteristics, and psychiatric comorbidity associated with sleep complaints specific to each sex among adults with MDE. These findings are crucial for precise diagnosis, personalized treatment, and improved clinical outcomes. METHODS: In a large nationally representative prospective survey, we used multi-adjusted logistic regression models including sociodemographic characteristics, psychiatric comorbidity, and depression severity to examine whether associations differ between men and women. RESULTS: Among women, 93.3 % reported at least one type of sleep complaints (i.e., trouble falling asleep, early morning awakening or hypersomnia) while 91.0 % of men did, with respectively 78.3 % and 77.2 % of insomnia complaints, and 46.2 % and 41.3 % of hypersomnia complaints. Women with sleep complaints were more likely to be black, with lower individual incomes, have histrionic personality disorder or a specific phobia. Conversely, men with sleep complaints were more likely to have a lifetime diagnosis of mania spectrum disorder, generalized anxiety disorder, drug use disorder, as well as dependent and schizotypal personality disorders. Surprisingly, being "never married" has emerged as a protective factor against sleep complaints in women, while posing as a risk factor in men compared to other marital statuses. Differences and specificities were also noted concerning subtypes of insomnia and hypersomnia complaints. LIMITATIONS: The cross-sectional design means the associations found do not imply causality. CONCLUSIONS: These findings provide insights into the complex relationship between sleep and depression in men and women, highlighting the need for personalized interventions.

Causal relationship between insomnia and thyroid disease: A bidirectional Mendelian randomization study.

OBJECTIVE: Some correlations between thyroid disorders and insomnia have been found in previous studies; however, the causal relationship between them is unclear. The aim of this study was to investigate the causal relationship between insomnia and five thyroid disorders (hyperthyroidism, hypothyroidism, thyroiditis, thyroid nodules, and thyroid cancer). METHODS: We assessed the causal relationship between insomnia and thyroid disorders using inverse variance weighted, weighted median, and Mendelian randomization (MR)-Egger analyses in MR analyses and then used inverse MR analyses to assess the causal relationship between thyroid disorders and insomnia. RESULTS: MR analysis showed that insomnia did not increase the risk of hyperthyroidism, hypothyroidism, thyroiditis, thyroid nodules, and thyroid cancer. However, reverse MR analysis showed that thyroid cancer increased the risk of insomnia (OR = 1.01, 95%CI: 1.00-1.02, p = .01), and the other four thyroid disorders had no direct causal relationship with insomnia. Sensitivity analyses indicated that the results were robust and no pleiotropy or heterogeneity was detected. CONCLUSION: This study did not find evidence of a bidirectional causal relationship between genetically predicted insomnia and hyperthyroidism, hypothyroidism, thyroiditis, and thyroid nodules. However, we found that although insomnia does not increase the risk of thyroid cancer, thyroid cancer does increase the risk of insomnia.

Efficacy and safety of acupuncture for the treatment of insomnia in breast cancer patients: A systematic review and meta-analysis.

BACKGROUND: Breast cancer-related insomnia is one of the most common symptoms in patients with breast cancer, and acupuncture has been increasingly used in the treatment. However, there has been no meta-analysis that specifically explores the efficacy and safety of acupuncture in treating insomnia related to breast cancer. OBJECTIVE: The aim of this review was to systematically analyze the existing literature through a meta-analysis to evaluate the effectiveness and safety of acupuncture for breast cancer-related insomnia. METHODS: Six medical databases were comprehensively searched for previous randomized controlled trials (RCTs) up to April 2024. The Pittsburgh Sleep Quality Index (PSQI) score was the primary outcome. The secondary outcomes include the Insomnia Severity Index (ISI), Sleep Onset Latency (SOL), Wake After Sleep Onset (WASO), Total Sleep Time (TST), and Sleep Efficiency (SE), and the later four outcomes were measured by Actiwatch and sleep diary, respectively. RESULTS: A total of seven articles with 434 participants were included. The meta-analysis revealed that acupuncture produced a significant improvement in the total PSQI score (MD 95 %CI = -2.16[-2.88, - 1.45], P < 0.001), but had no statistical significance on ISI scores compared with controls (MD 95 %CI = -1.53[-3.97, 0.91], P = 0.22). From the Actiwatch, there was no substantial disparity observed in the enhancement of Sleep Onset Latency (SOL) (MD 95 %CI = -6.40[-13.19, 0.39], P = 0.06), Wake After Sleep Onset (WASO) (MD 95 %CI = -1.45[-7.09, 4.20], P = 0.62), or Total Sleep Time (TST) (MD 95 %CI = 3.54 [-4.71, 11.79], P = 0.40) between the experimental group and the control group. However, a significant distinction was observed in Sleep Efficiency (SE) improvement (MD 95 %CI = 2.43 [0.14, 4.72], P = 0.04). From the sleep diary, there was a significant difference in the amelioration of SOL (MD 95 %CI = -9.15[-16.48, - 1.81], P = 0.01), TST (MD 95 %CI = 29.92 [16.74, 43.10], P < 0.001), and SE (MD 95 %CI = 4.57 [1.92, 7.23], P = 0.0007) between the experimental group and the control group. However, no significant divergence was observed in the improvement of WASO (MD 95 %CI = 4.53[-4.81, 13.87], P = 0.34). All reported acupuncture-related adverse events were mild in severity. CONCLUSIONS: Acupuncture can partially alleviate insomnia symptoms in breast cancer patients. Moreover, acupuncture is safe and may serve as a dependable alternative therapy in clinical settings. Owing to the limited number of studies included, potential biases of heterogeneous interventions, and methodological weaknesses of long-term follow-up, more high-quality RCTs with large sample sizes should be conducted to evaluate acupuncture treatment.

Validation of the Athens Insomnia Scale Among Young Chinese Male Population in a High-Altitude Situation.

Purpose: The Athens Insomnia Scale (AIS) is a widely used and authorized questionnaire for evaluating insomnia symptoms. However, its reliability and validity at high altitudes are uncertain. Therefore, this study aimed to confirm the validity and reliability of AIS during a 3658 m altitude exposure. Patients and Methods: A total of 387 young Chinese males were enlisted in the acute high-altitude exposure group. They flew for about two hours, climbing from 400 m to 3658 m. The high-altitude-acclimated group consisted of 86 young Chinese men who had lived at least six months at 3658 m altitude. The sleep quality of the acute high-altitude exposure group was evaluated using the AIS before the ascent and after exposure to 3658 m for 24 hours, and one week. The sleep quality of the high-altitude-acclimated group was also assessed. The AIS's internal consistency, reliability, and validity were evaluated. Results: The respondents' quality of sleep significantly decreased after being exposed to 3658 m as opposed to 400 m. Two factors comprised the AIS, according to an exploratory factor analysis: "sleep problem" (items 1-5) and "daytime dysfunction" (items 6-8). The Cronbach's α internal consistency coefficients exceeded 0.8, and the corrected item-total correlations were all greater than 0.5 when the subjects were exposed to 3658 m. The model fit index was well within the criterion. The average variance extracted and composite reliability were all higher than 0.5 and 0.7, respectively. The interclass correlation coefficient was deemed "fair to good" at 0.482, which is greater than the 0.4 threshold. The AIS has satisfactory discriminant validity, as shown by the Fornell-Larcker criterion and cross-loading results. The daytime dysfunction R-square values (>0.33) show that the frameworks have considerable predictive accuracy. Conclusion: The AIS exhibits strong consistency, reliability, and validity. The AIS's features and simplicity make it an essential psychometric tool for high-altitude sleep research.

Factors Associated With the Use of Over-the-Counter Sleep Aids Among Jazan University Students.

BACKGROUND: Sleep aids, classified by their mechanisms of action, can promote sleep but may be misused, leading to harm. Exercise and pharmacological interventions like antihistamines, melatonin, and benzodiazepines also help manage sleep disorders. In Saudi Arabia, sleep disorders are prevalent, especially among university students. OBJECTIVES: Our study examines the prevalence and usage of the medication containing diphenhydramine hydrochloride, among Jazan University students, aiming to inform better practices and highlight related risks and benefits. METHODS: A cross-sectional design study was conducted among Jazan University students in Saudi Arabia. The sampling of data utilized random selection. Data was cleaned in Excel and analyzed using IBM SPSS Statistics for Windows, Version 29 (Released 2023; IBM Corp., Armonk, New York, United States). RESULTS: Our study comprised 437 participants from Jazan University aged 18-25 years. The majority reported earning less than 5000 SAR monthly and were unmarried (91.8%). Remarkably, 13.7% of participants were diagnosed with insomnia. Sleep aid containing diphenhydramine hydrochloride, utilized for mild to moderate pain relief and sleep induction, was the most prevalent medication, with 56.3% of participants having used it and 9.4% using it continuously for over 10 nights. Significant predictors for usage of sleep aids containing diphenhydramine hydrochloride included gender (p=0.041), with male students exhibiting higher usage rates, and college type (p<0.001), particularly medical students. Multivariate analysis confirmed male gender and enrollment in medical colleges as robust predictors. Age, income, marital status, and employment variables showed no significant associations. CONCLUSIONS: Our study highlights a considerable prevalence of sleep aids containing diphenhydramine hydrochloride usage among Jazan University students, notably influenced by gender and college type. Male gender and enrollment in medical colleges emerged as significant predictors of their usage.

Efficacy of digital brief behavioural treatment for insomnia using a smartphone application in conjunction with light therapy in university students with insomnia symptoms with late chronotypes: A pilot randomized-controlled trial.

The efficacy of digital brief behavioural treatment for insomnia using a smartphone application in conjunction with light therapy was investigated in university students who had insomnia symptoms with late chronotypes. In this two-arm parallel randomized-controlled trial, participants with insomnia symptoms and late chronotypes were recruited between October and November 2023. The duration of the intervention program was 4 weeks. The smartphone application provides digital brief behavioural treatment for insomnia, including programs for advanced phases. The intervention group used blue-light-emitting diode glasses in the morning after waking up for 2-4 weeks. The primary outcome was a change in the Insomnia Severity Index during the study period. The Insomnia Severity Index was obtained weekly using a web questionnaire. Of the 28 students, 14 each were assigned to the intervention and control groups. The mean Insomnia Severity Index scores at baseline were 12.2 and 12.5; after 4 weeks, they declined to 7.2 and 10.6 in the intervention and control groups, respectively. Primary analysis using a linear mixed model showed a significant improvement in the temporal trends of the Insomnia Severity Index in the intervention group (p < 0.001). The scores on the Morningness-Eveningness Questionnaire (p = 0.008) and RU-SATED (p = 0.005) significantly improved in the intervention group relative to the control group following the intervention. This study demonstrated the effectiveness of the digital brief behavioural treatment for insomnia with light therapy in participants with both insomnia symptoms and late chronotypes.

Effect of a prescription digital therapeutic for chronic insomnia on post-treatment insomnia severity, depression, and anxiety symptoms: results from the real-world DREAM study.

Introduction: Chronic insomnia is a substantial public health burden that often presents with co-occurring depression and anxiety. Randomized clinical trials and preliminary real-world evidence have shown that digitally delivered cognitive-behavioral therapy for insomnia (dCBT-I) is associated with improvements in insomnia, but real-world evidence is needed to determine the true impact of digital CBT-I. This pragmatic study aimed to evaluate the benefits of treating chronic insomnia with a tailored prescription digital therapeutic in a real-world population. Methods: This prospective, single-arm clinical study involved adults aged 22-75 with chronic insomnia living in the US who had access to a mobile device. Participants accessed the FDA-cleared prescription digital therapeutic (PDT; Somryst®) over a 9-week intervention period. The PDT delivers cognitive-behavioral therapy for insomnia via six interactive treatment cores and daily sleep diaries used for tailoring treatment. Participants completed validated patient-reported instruments at baseline, before completing treatment cores, immediately post-intervention, and at 6-month and 1-year follow-ups. The Insomnia Severity Index [ISI], the 8-item Patient Health Questionnaire [PHQ-8], and the Generalized Anxiety Disorder-7 scale [GAD-7] were used to determine the effect of the PDT on insomnia, depression, and anxiety. Results: After screening, 1565 adults accessed the PDT. 58% of those who began the program completed Core 4, established as exposure to all mechanisms of action in the digital therapeutic. For those who completed assessments for all 6 cores (48.4%), the ISI was lowered from 18.8 to a mean of 9.9 (P <.001). These scores continued to be lower than baseline at immediate post (11.0), 6-month (11.6), and 1-year follow-ups (12.2) (P <.001). The results of the PHQ-8 and GAD-7 also show significant decreases at all measured timepoints from baseline (P <.001). Of the patients that began the program, 908 (58.0%) were considered adherent and 733 (46.8%) completed all 6 cores. Conclusion: Data from the DREAM study contributes to the growing body of clinical evidence of how patients are utilizing a PDT in the real world, outside of controlled settings, offering insights for clinicians who use these therapeutics in practice. Clinical trial registration: ClinicalTrials.gov, identifier NCT04325464.

Restoration of abnormal sleep EEG power in patients with insomnia disorder after 1Hz rTMS over left DLPFC.

Introduction: Hyperarousal has been a significant pathophysiological theory related to insomnia disorder (ID), characterized by excessive cortical activation and abnormal electroencephalogram (EEG) power during daytime or sleep. However, there is currently insufficient attention to the EEG power during rapid eye movement (REM) sleep and different stages of non-rapid eye movement (NREM) sleep. Additionally, whether the abnormal sleep EEG power in ID patients can be restored by repetitive transcranial magnetic stimulation (rTMS) remains unclear. Methods>: Data of 26 ID patients and 26 healthy controls (HCs) were included in the current observational study. The comparisons of relative power between patients and HCs at baseline in each band of each sleep stage and the changes in patients before and after rTMS treatment were performed. The correlations between relative power and behavioral measures of the patients were also investigated. Results: Abnormalities in sleep EEG relative power in the delta, beta and gamma bands of the patients were observed in NREM2, NREM3 and REM sleep. Correlations were identified between relative power and behavioral measures in ID group, primarily encompassing sleep efficiency, sleep onset latency and depression scores. Post-treatment improvements in relative power of the delta and beta band were observed in NREM2 sleep. Discussion: The relative power of sleep EEG exhibited a significant correlation with sleep measures in ID patients, and demonstrated notable differences from HCs across the delta, beta, and gamma frequency bands. Furthermore, our findings suggest that rTMS treatment may partially ameliorate relative power abnormalities in patients with ID.

Expanded gray matter atrophy with severity stages of adult comorbid insomnia and sleep apnea.

OBJECTIVE: To investigate gray matter volume (GMV) changes in patients with comorbid insomnia and sleep apnea (COMISA) of differing severity and relationships between GMV alterations and clinical measures. METHODS: Thirty-four COMISA patients and 24 healthy controls (HC) were recruited. All patients underwent structural MRI and completed measures related to respiration, sleep, mood, and cognition. COMISA patients were further divided into a mild and moderate COMISA (MC) and a severe COMISA (SC) group. Changes in GMV of COMISA patients were investigated via VBM. The voxel-wise differences in GMV were compared between HC group and COMISA group. Analysis of covariance (ANCOVA) was performed on individual GMV maps in MC, SC, and HC groups to further investigate effects of different stages of COMISA severity on GMV. Partial correlation analysis was then performed to analyze relationships between altered GMV and clinical measures. RESULTS: GMV atrophy was mainly located in the temporal lobes and fusiform gyrus in COMISA group. The post-hoc analysis of the ANCOVA revealed temporal lobes and fusiform gyrus atrophy in MC and SC groups compared to HC and the temporal lobe atrophy was expanded in SC group based on cluster size. Moreover, the SC group showed GMV atrophy of the right amygdala compared to both MC and HC groups. Partial correlation analysis revealed positive relationships between the GMV and mood-and cognitive-related measures and negative correlation between GMV and respiration measure. CONCLUSIONS: Our findings showed GMV atrophy expansion from temporal lobe to limbic system (right amygdala) as severity stages increase in COMISA patients. These findings contribute to our understanding of neurobiological mechanisms underlying different stages of severity in COMISA patients.
