Active clinical trials for "Sleep Initiation and Maintenance Disorders"

Insomnia and OSA coexist in clinical populations, but the prevalence of comorbid insomnia among OSA patients in the community and risk factors remain poorly known. Little is known about the impact of sleep apnea and insomnia on the quality of life and quality of sleep compared to the presence of one of the sleep disorders alone. Our hypothesis is that the co-existence of OSA and insomnia is high in our community. We also hypothesized that the co-existence of OSA and insomnia promotes greater impairment of quality of life and quality of sleep when compared to the presence of OSA or insomnia alone. Patients referred to polysomnography will be submitted to 6 questionnaires to assess daytime sleepiness (EPWORTH), insomnia severity index (ISI), anxiety and depression assessment (Beck's anxiety and depression inventory), quality of life assessment(WHOQOL- BREF) and sleep quality assessment (Pittsburgh questionnaire) and they will also be submitted to a polysomnography type III. It will be calculated the frequency of insomnia, OSA and the comorbidity between insomnia and OSA in the sample. It will be analysed correlations between the insomnia severity index, apnea and hypopnea index, Epworth sleepiness scale, quality of life scale (WHOQOL-BREF), anxiety and depression scale (Beck's anxiety and depression inventory) and Pittsburgh sleep quality scale. Insomnia severity index scores, Epworth sleepiness scale, quality of life scale (WHOQOL-BREF), anxiety and depression scale (Beck anxiety and depression inventory) and Pittsburgh sleep quality scale will be compared according to the presence and absence of OSA and the presence and absence of insomnia and the presence of the comorbidity insomnia and OSA.

Behavioral insomnia of childhood (BIC) is a common problem in early infancy. The whole family is affected by the problem, but research usually relies only on maternal perception and report. This mixed-method study aimed to explore maternal and paternal perspectives about their child's sleep and sleep problems in early childhood. Secondly, infants' sleep will be measured objectively with actigraphy. Parental mental health, marital relationship and sleep will be evaluated in order to explore the effects on the perception of their infant's sleep.

The investigators hypothesized that depression is associated with home sleep EEG, subjective sleepiness and insomnia symptoms. To test this, the investigators plan to perform sleep examination with single channel EEG, in combination with questionnaire survey for insomnia, sleepiness, depression and job stress to Koka city government employees.

The aim of this study is to investigate the levels of insomnia 3 months after (T2) the strict physical distancing government initiated physical distancing protocols related to the COVID-19 pandemic (T1). The study also aims to investigate how predictors measured after and before the COVID-19 pandemic are associated with sleep problems at T2.

This study combined the insomnia syndrome with PSG, fMRI, neuroactive substance detection, and infrared heat map, observing the electrophysiological changes of insomnia patients with different syndromes,localizing brain function excitation zone and changes in neuroactive substances,and the response of the visceral function to the infrared Image，which reveal the biological material basis of insomnia syndrome, and analyze it's correlation with infrared Image, providing a scientific, objective and visual technical method for TCM diagnosis and treatment of insomnia.

The investigators will conduct a single-center case series study. A total of 40 participants with insomnia will be enrolled. The aim of the study is to assess the therapeutic effect of head-point acupuncture for the treatment of insomnia.

To analyze the relationship of nocturnal concentrations of melatonin, γ-aminobutyric acid and total antioxidants with insomnia after stroke.

Mindfulness training has been gaining popularity in the past decade as a means of improving general well-being. This trend appears in response to the new stressors that have arisen with the increased stress of the 21st century. Studies have shown that the psychological state of metacognitive awareness encapsulated in mindfulness can promote the decreasing of stress as well as the secondary effect of improving sleep quality; both outcome measures of this study. While the body of research evaluating these benefits is growing, there is limited emphasis placed on the individual differences that can affect the overall efficacy of mindfulness training. Our aim in this study is to observe the effects of mindfulness training on perceived stress levels as well as on sleep using subjective measures in a large sample of trainees. To achieve this, participants will be recruited from a pool of people who have signed up for a 4-week foundational mindfulness or 8-week mindfulness based stress reduction course at Brahm Centre. Questionnaires will be administered both before and after these courses to evaluate both stress levels and sleep habits as well as other factors which could contribute to the efficacy of mindfulness training. These inventories will probe the different facets of interpersonal differences that could serve to influence the effectiveness of the mindfulness intervention. In addition, the investigators will also test the effect of conducting the course online during a situation of emergency, like it is the partial lockdown that was implemented in Singapore due to the spread of Covid-19. The proposed study has the potential to provide new insights into the factors that affect the efficacy of mindfulness on stress and sleep, in a situation of non-emergency (until February the 6th 2020) as well as during a period of heightened restrictions (DORSCON Orange, from 7th of February to 6th of April 2020) and a partial lockdown (from 7th of April to 1st of June 2020, or until resume of normal activity). Further, the investigators hope to build an algorithm that can predict the potential effectiveness of mindfulness on a person by person basis. This could serve as a foundation for future recommendations for mindfulness training as well as open the door for future studies that could serve to further customize the mindfulness training framework to accommodate individual differences

Insomnia is one of the most main diseases of civilization in the world, which chronic insomnia is up to 30% in Taiwan under the latest statistics and a common disease which appears to sleep difficultly, sleep interrupted, wake up early or wake up still tired. Long-term persistence of these symptoms will lead to the occurrence of mental illness and then affect people's emotional behavior and cognitive memory, showing that insomnia is an important modern health issues. Recently, "individual response patterns" was proposed by modern medicine. This thinking process and spirit seems to be compatible with the traditional Chinese medicine (TCM) therapy of "Differential Treatment". The purpose of this study, the Athens Insomnia Scale (AIS), commonly used to quickly screen for insomnia patients and the evaluation of Western medicine efficacy in Western medicine clinic, and investigation of Syndrome Type of TCM to find out whether with Syndrome Type of TCM and AIS in the associated factors, and confirm the necessity and importance of Syndrome Type of TCM, for future reference and basis for the development of integrated medicine. In the cross-section study with an interview on survey, sampling Miaoli County an Chinese medicine clinic, in line with standard sampling of 200 patients with insomnia were recruited. The questionnaires contained two instruments including Athens Insomnia Scale (AIS), and Syndrome Type of TCM questionnaire. Cross-table, chi-square test, variance analysis and Pearson product-moment correlation was used to find the relation.

The primary purpose of this study is to discover, establish and refine the individual treatment protocol of each TCM expert for insomnia, and to explore what characteristics of the patients are considered with the corresponding treatment in clinical practices. The secondary purpose is to determine the effectiveness of TCM pattern differentiation treatment for the patients with insomnia.
