Photobiomodulation for Reducing Sedative-Hypnotic Use:Clinical Trial of a Light-Therapy Device

Background: Insomnia is a prevalent and growing public health issue, with one in three adults affected globally and one in five Taiwanese adults reporting significant sleep disturbances. Long-term use of sedative-hypnotic medications remains common in Taiwan despite clinical guidelines recommending short-term use only, contributing to adverse outcomes such as impaired sleep architecture, cognitive deficits, and elevated dementia risk. Non-pharmacological interventions-particularly light-based therapies-offer promising alternatives but existing bright-light therapy is limited by melatonin suppression and the need for precise daytime timing. Recent advances in photobiomodulation (PBM) suggest that red and near-infrared light, which do not suppress melatonin, may enhance sleep quality and support glymphatic clearance when applied during sleep. Preliminary findings from our prior NSTC-funded industry-academia project demonstrated that 850-nm PBM applied during sleep improved subjective sleep quality and sleep duration among older adults with insomnia who were not using hypnotics. Building on these results, the present study aims to evaluate whether sleep-period PBM can improve sleep quality, enhance daytime alertness and cognitive function, and reduce sedative-hypnotic medication use among adults with chronic insomnia who regularly use these medications. Methods: The study will employ an 8-week, single-blind, randomized controlled trial with two parallel arms: (1) PBM intervention and (2) inactive sham control. We will develop an engineer-certified wearable PBM prototype integrating near-infrared LEDs. Sixty adults who use sedative-hypnotics ≥4 days per week will be recruited. Participants will be randomized in a 1:1 ratio and instructed to use the assigned device applied at acupoints Ex-HN 22 continuously during the sleep period. Outcomes will be assessed at baseline, week 4, and week 8. Primary outcomes include changes in subjective sleep quality (PSQI), hypnotic use frequency, and objective sleep parameters measured by wrist actigraphy. Secondary outcomes include daytime sleepiness (KSS), emotional symptoms (BDI and BAI), and psychomotor vigilance task performance. Expected contributions: This study is expected to generate clinical evidence in Taiwan evaluating nighttime PBM for insomnia in hypnotic-using populations, address the unmet need for portable, home-based, non-pharmacological sleep interventions, and support future commercialization of a sleep-compatible light therapy device. Results will inform device optimization, regulatory approval strategies, and market expansion efforts in the growing global sleep-health industry.

Group-Based Brief Behavioral Therapy for Insomnia for Patients With Chronic Mental Illness

The goal of this clinical trial is to evaluate the effectiveness of a short-term, group-based Brief Behavioral Therapy for Insomnia (BBTI) intervention in chronic psychiatric patients at a hospital day ward.The main questions it aims to answer are: 1. Does the BBTI-based group intervention improve subjective sleep quality and reduce the severity of insomnia? 2. Does the intervention have a positive effect on psychological well-being and cardiometabolic/physical functions? Researchers will compare an experimental group to a waitlist control group to see if the intervention improves sleep quality, reduces insomnia-perpetuating behaviors, and enhances overall health status across various timeframes. Participants will: 1. Attend four sessions that cover sleep structure education, relaxation techniques (including acupressure), sleep-promoting diet principles, and the proper use of sedative-hypnotic medications. 2. Write a daily sleep diary. 3. Complete three times of structured self-report questionnaires. 4. Undergo physiological and physical function assessments.

Clinical Trial for Acupuncture in Adolescents With Psychological Distress and Insomnia

This is an assessor-blinded, randomized, MAS-controlled trial. A total of 148 adolescents aged 15-22 years experiencing mild to moderate anxiety or depressive symptoms will be recruited. They will be randomly assigned to DCEAS+BA (n = 74) and MAS (n = 74) for 2 sessions per week for 8 weeks, followed by a 4-week post-treatment observation period. A post-intervention visit will be held at week 12. The primary outcome will be assessed using the Chinese version of the Beck Anxiety Inventory (BAI-C). The secondary outcomes include the Beck Depression Inventory II (C-BDI-II) for depression, the Zung Self-Rating Anxiety Scale (SAS) and the Zung Self-Rating Depression Scale (SDS) as additional assessments for anxiety and depression, the Pittsburgh Sleep Quality Index (PSQI) for sleep quality, and the World Health Organization Quality of Life-Brief (WHOQOL-BREF) (HK version) for the general quality of life. Assessment will be carried out every 4 weeks till week 12, while saliva will be collected at baseline and at the end of the 8 weeks. Salivary oxytocin and cortisol will be analyzed. A generalized linear mixed-effect model will be applied to compare treatment outcomes over time in the two groups and linear regression will be conducted to examine intercorrelations among clinical improvement and changes in biomarker levels. Subgroup analysis will be conducted to identify specific effects of DCEAS+BA.

Assessment of Light Therapy in Insomnia Disorder

Sleep disorders represent a major public health issue and the leader in these disorders is insomnia with 10 to 15% of subjects in the general population reporting symptoms of insomnia with a daytime impact. In addition to being very common, insomnia leads to an increase in morbidity and mortality and weighs on healthcare systems worldwide. Despite this public health context, insomnia is underdiagnosed and rarely treated. Hypnotics have proven efficacy but with a risk of dependence and pharmacotolerance which appears within a few weeks. Cognitive behavioral therapy (CBT) has a good level of evidence and is now a benchmark treatment for the management of insomnia. Unfortunately, not all patients adhere to or respond to these procedures, which cannot be implemented for many of them either. There is therefore a need to identify other alternative therapeutic strategies, and we believe that exposure to light is a promising treatment. In this perspective, it seems interesting to assess the effect of the propensity to fall asleep with an exposure to light therapy in patients suffering from insomnia. In order to be in optimal ecological conditions, we want to use a portable light therapy device which allows easy, acceptable and ambulatory exposure. If the lighttherapy is confirmed in insomnia under ecological conditions, this would make it possible to propose a new non-drug treatment, easy to access and on a large scale

Efficacy of Cognitive Behavioural Therapy for Insomnia and Bright Light Therapy in Adolescents With ADHD, Insomnia, and Evening Chronotype

Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterised by persistent inattention, hyperactivity, and impulsivity. In adolescents and young people, ADHD is commonly accompanied by insomnia and circadian delay. These co-occurring sleep and circadian disturbances may negatively affect daytime functioning and overall clinical outcomes. Although cognitive behavioural therapy for insomnia (CBT-I) is considered the first-line treatment for insomnia, and bright light therapy may help address circadian issues, their efficacy in adolescents with ADHD and comorbid insomnia and eveningness remains unexplored. This study aims to evaluate whether CBT-I, with or without bright light therapy, improves insomnia, sleep, and circadian as well as other clinical outcomes, and cognitive functioning in youths with ADHD and whether these interventions can also lead to improvements in mood and other clinical symptoms, as well as cognitive functioning.

Addressing Nocturia in Older Women Utilizing Behavioral Sleep Intervention and Brief Mindfulness

The goal of this clinical trial is to examine and compare the effect of behavioral sleep treatment: BBTI (brief behavioral treatment of insomnia) and brief mindfulness (MI), independently and combined vs control on frequency of nighttime awakenings to void (nocturia) and on nighttime urine production in older women over the age 65 years with nocturia. To study the effect of these treatments, participants will be randomly assigned to one of the following groups 1) BBTI alone, 2) MI alone, 3) BBTI+MI, or 4) control: sleep information only without any structured sleep or mindfulness therapy. The study aims to examine the effect of these therapies at end-of-treatment (week 4), as well sustained effects at 3- and 6-months. The main questions the study aims to answer are: 1. do these treatments reduce the frequency of nighttime awakenings to void 2. do these treatments reduce the volume of nighttime urine production 3. do these treatments improve sleep quality Frequency of nocturia and sleep quality will be assessed via questionnaires and nighttime urine volume using bladder-sleep diaries which is 3-day record participants will complete at home documenting every time they go to the bathroom and volume they voided. In addition, sleep and sleep interruptions will also be assessed using an FDA-cleared home sleep testing device called Zmachine®.

The WISE Study (WhatsApp Intervention for Sleep in the Elderly)

Sleep hygiene education is an educational effort to teach healthy sleep habits and behaviors to improve sleep quality, duration, and regularity naturally without the use of medication; however, this approach has not been established in Indonesia. This study aims to establish a sleep hygiene education care model among lonely older adults with insomnia in Indonesia and to examine the immediate effects of the WISE Study (WhatsApp Intervention for Sleep in the Elderly) led by nurses to older adults loneliness with insomnia using a Digital Booklet. In this assessor-blinded, randomized controlled trial, participants will be randomly allocated to either the nurse-led WISE experimental group or the control group provided with usual care. The outcomes will include sleep parameters measured using the Indonesian version of the Insomnia Severity Index (ISI), Generalized Anxiety Disorder-7 (GAD-7), Geriatric Depression Scale-Short Form (GDS-SF), Brief Fatigue Inventory (BFI), Epworth Sleepiness Scale (ESS), and sleep diaries. The questionnaires will be assessed at pre-treatment, post-treatment, and one-month follow-up. Generalized estimating equations will be used to test the research hypotheses. Questionnaires will be assessed at pre-treatment, post-treatment, and one-month follow-up. We hypothesized that older adults who were loneliness with insomnia who underwent nurse-led WISE would experience greater improvements in sleep quality compared to participants in a control group who received usual care.

Self-Help Booklets for Sleep in Adults With Pulmonary Hypertension

The researchers have developed a set of self-help booklets for adults with pulmonary hypertension (PH) who are experiencing sleep problems. The booklets include sleep hygiene advice and are based on a psychological treatment called Cognitive Behavioural Therapy for Insomnia (CBT-I). CBT-I is a structured, evidence-based treatment for ongoing sleep problems. It helps people understand how their thoughts, behaviours, and daily routines can affect their sleep. It aims to improve sleep quality and help people fall asleep more easily and get back to sleep if they wake during the night. CBT-I is one of the most effective treatments for ongoing sleep problems. The self-help programme consists of four booklets, which participants will work through at home over four weeks, completing one booklet each week in their own time. The aim of the study is to find out whether the self-help booklets improve sleep quality in people with pulmonary hypertension. Participants will be asked to complete questionnaires about their sleep and mental wellbeing, including symptoms of anxiety and depression. Participants will then be randomly allocated to one of two groups. The intervention group will receive the self-help booklets during the study. The wait-list group will receive the booklets at a later date if they are found to be helpful. Having two groups allows the researchers to compare the results and determine whether any improvements in sleep are due to the self-help booklets. Participants in the intervention group will also be contacted during the programme to ask about their experiences of using the booklets. Both groups will complete the questionnaires again after four weeks and then again one month later. Participants in the intervention group will also be contacted at the end of the study to discuss their experiences of taking part.

Study on the Management of COMISA

COMISA, the combination of obstructive sleep apnea (OSA) and insomnia, is a frequent and burdensome condition. Many patients with OSA experience clinically significant insomnia symptoms, and a substantial proportion of individuals with chronic insomnia also meet criteria for OSA. This comorbidity is associated with more severe symptoms, more complex diagnostic pathways, and reduced adherence to continuous positive airway pressure (CPAP) therapy. This study aims to better understand COMISA and evaluate whether adding daridorexant to CPAP treatment can improve treatment adherence and overall patient outcomes.

Evolution of Insomnia During the First Year in Patients Newly Diagnosed With Cancer

The diagnosis of cancer can be a major trigger for new sleep problems, especially insomnia, in people who did not have sleep issues before. Insomnia may appear early in the care pathway and can continue over time, often interacting with other physical or emotional symptoms. The main goal of this preliminary study is to describe how insomnia develops during the first months after a cancer diagnosis in patients who had no sleep problems at the time of diagnosis. This will be done through regular follow-up over time. A secondary aim is to identify the factors that may contribute to the onset or persistence of insomnia, such as the cancer treatments patients receive, as well as any medical or non-medical therapies used to manage sleep difficulties. The study will also look at whether patients who develop sleep problems are referred to psychologists trained in specific therapies for insomnia, and how well they follow and adhere to these treatments.

Cognitive Behavioural Therapy for Insomnia Among Young People With Moderate Level of Mental Distress in Hong Kong

This randomized controlled trial (RCT) aims to evaluate the effectiveness of a Cognitive Behavioral Therapy for Insomnia (CBTi) intervention in enhancing sleep quality, overall quality of life, functional ability, and reducing mental distress among at-risk youths in Hong Kong. Participants are youths with moderate mental health concerns, indicated by K6 scores ranging from 11 to 14. The study involves 160 participants who will be randomly assigned to either the intervention group or a wait-list control group. Participants assigned to the intervention group will receive six weekly face-to-face sessions led by trained youth workers, while those in the control group will receive the same intervention after the initial follow-up period. Participants will be evaluated at baseline, post-intervention, and one-month follow-up. An interim analysis is built for the sake of evaluation of the collected data from the ongoing trial, in which the primary research question is addressed, and which has the potential for modifying the conduct of the study. Furthermore, a qualitative follow-up will be conducted after the trial, involving both participants and the workers delivering the CBTi intervention. This qualitative component aims to gather feedback on participants' experiences, and inform potential revisions to enhance future implementation. It is hypothesized that youths receiving the CBTi intervention will show significantly greater improvements in sleep quality, quality of life, and functioning, along with reductions in mental distress, as well as depressive and anxiety symptoms, compared to those in the wait-list control group.
