Sleep Homeostasis in Primary Insomnia
Primary InsomniaAbout 10% of the population is believed to suffer from Primary Insomnia. It is also believed that people with chronic insomnia have a sleep system that is essentially out of alignment (we call this "homeostatic dysregulation"). We also know that a certain form of non-medication therapy called cognitive-behavioral therapy is a very effective treatment for insomnia. It is not known, however, whether cognitive-behavioral therapy actually works by bringing the brain's sleep system back into alignment ("sleep homeostasis"). One of the methods used to measure sleep homeostasis is to observe a person's brain waves during sleep and particularly during sleep that follows a period of sleep loss. The purposes of this study are to first learn whether persons with insomnia do have a misaligned sleep system compared to persons who do not have insomnia by assessing the sleep of people before and after a period of extended sleep loss. Second, the study will determine whether cognitive-behavioral therapy can re-regulate the sleep system and its response to sleep loss. Third, the final purpose is to examine whether the immune system of people with insomnia is more altered following sleep loss than in the comparison group and whether cognitive-behavioral therapy can alter immune function.
Paroxetine in the Treatment of Chronic Primary Insomnia
Primary InsomniaDepressionThe goal of the study is to examine the role of paroxetine, an antidepressant medication, in the acute and continuation treatment of insomnia. Primary insomnia is a type of insomnia not directly resulting from general medical, chemical, or psychiatric conditions.

Group Cognitive Behavioral Therapy and Acupressure for Insomnia
InsomniaThis study will examine the use of cognitive behavioural therapy (CBT) and acupressure in treating insomnia in Chinese adults. The main components of CBT for insomnia (CBT-I) includes psychoeducation, sleep restriction, stimulus control, cognitive restructuring, and relaxation. CBT-I is widely used in western countries but it fails to address patient preference among Chinese adults with insomnia, as demonstrated in a previous study examining the subjective experience of chronic insomnia in Hong Kong Chinese adults. The study revealed that Chinese adults showed distrust in hypnotics and preferred traditional Chinese medicine (TCM) which was believed to be more natural. In order to maximize the therapeutic effects of psychological interventions for insomnia, integrative medicine with a combination of CBT-I and TCM could be an alternative to address insomnia in the Chinese population. Acupressure, a non-invasive therapy, is commonly used in TCM. It is suggested that acupressure can induce relaxation and improve sleep quality. Some studies have demonstrated the separate efficacy of CBT-I and acupressure in treating insomnia. However, few studies have examined the effect of their combination.
E-aid Cognitive Behavior Therapy for Insomnia to Prevent Transition From Acute Insomnia to Chronic...
InsomniaAcute insomnia is one of the most common sleep disorders. Online cognitive behavioral therapy for insomnia (e-aid Cognitive Behavioral Therapy for Insomnia, eCBTI) has received wide attention in recent years. Foreign countries already have some eCBTI treatment tool, shown similar efficacy as standard CBTI, but how eCBTI can help in acute insomnia require further exploration and examination. In this study, Investigators will establish eCBTI treatment tool to test whether eCBTI can reduce the conversion of acute insomnia to chronic insomnia disorder; and whether they can improve insomnia symptoms, sleep-related symptoms, anxiety and depressive symptoms, and quality of life
Treatment of Insomnia for Adolescents With Mild Traumatic Brain Injury
Mild Traumatic Brain InjuryPost-Concussion Syndrome1 moreA substantial number of children and adolescents sustain a mild traumatic brain injury (mTBI) each year. Although research supports that the vast majority of youth will recover quickly and return to normal functioning, some adolescents continue to report problems long after the injury. Disturbed sleep, notably trouble with sleep onset and sleep maintenance, is a frequently reported problem in those with slow recovery from a mTBI. Poor sleep is also associated with cognitive complaints, mood disturbance, and lower quality of life. Despite the identification of sleep disturbance as a problem associated with slow recovery, there are very few treatment options. Cognitive-behavioural therapy for insomnia (CBT-I) has shown promise in children and adolescents as an effective treatment for sleep disturbance, although it has yet to be applied to the adolescent mTBI population who also present with sleep problems. The objective of this study is to examine the treatment of sleep disturbance using cognitive-behavioural therapy for insomnia (CBT-I) in those adolescents who have a protracted recovery from their mTBI. This represents a novel treatment option for this patient population and is anticipated to improve outcomes and quality of life.
Controlled Study of Chain Blanket for Insomnia
InsomniaThe aim of the study is to compare an intervention with a weighted metal chain blanket of 8 kg with a control plastic chain blanket of 1,5 kg for patients with Major depressive disorder, bipolar disorder, Generalized Anxiety Disorder (GAD) and/or attention deficit hyperactivity disorder (ADHD) and co-occurring insomnia. Patients are evaluated by a rater blind to treatment allocation with Insomnia Severity Index (ISI), Fatigue Symptom Inventory (FSI), Hospital Anxiety and Depression Scale (HAD) and actigraphy before, during and at primary end-point after 4 weeks use of the blanket.
