Filter by:Mild traumatic brain injuries (mTBI) or "concussions" are an increasingly prevalent injury in our society. Patients with post-concussion syndrome have been shown to have deficits on tests of short term memory, divided attention, multi-tasking, information processing speed, and reaction time, as well as alteration in mood and emotional functioning. Many patients have other vague complaints including fatigue, dizziness, irritability, sleep disturbances, and chronic headaches. Furthermore, sleep disruption of one of the most common complaints in patients suffering from traumatic brain injuries, with as many as 40 to 65% of patients with mTBI complaining of insomnia. Sleep problems in these patients are associated with poorer outcome, while resolution of the sleep disturbance is associated with improvement in cognitive functioning. Despite recent evidence of the correlation between sleep quality and recovery from traumatic brain injury, and the well-established role of sleep in neural plasticity and neurogenesis, there have been virtually no direct studies of the causal effects of sleep on recovery following mTBI. However, it is quite likely that sleep plays a critical role in recovery following brain injury. A particularly promising non-pharmacologic approach that shows potential in improving/modifying abnormalities of the circadian rhythm and sleep-wake schedule is bright light therapy. For the proposed investigation, we hypothesize that bright light therapy may be helpful in improving the sleep of patients with a recent history of mTBI and may also have other mood elevating effects, both of which should promote positive treatment outcome in these individuals. Bright light therapy may increase the likelihood that they will recover more quickly, benefit more extensively from other forms of therapy, and build emotional and cognitive resilience.
The primary aim of the study is to test the effect of mindfulness training on sleep parameters among older adults with insomnia symptoms The secondary aims are to examine if changes in mindfulness meditation practice (daily log) and level of mindfulness (self-report) are associated with changes in sleep parameters, and to determine if mindfulness training is associated with in vitro biological markers of peripheral inflammation
Previous research has shown that sleep quality in hemodialysis patients is disturbed. One of the possible explanations is an insufficient or disturbed melatonin rhythm. Melatonin rhythm is regulated by exposure to light. In this feasibility study, the investigators examine the effects of light therapy during dialysis on sleep, melatonin rhythm and mood.
Night waking with crying can be a distressing and difficult experience for infants and their parents. The investigators want to reduce infant night waking and crying and improve parents' views of their infants' sleep. This study will help the investigators determine whether parents who receive group teaching about infant sleep and follow-up phone calls provided by Public Health Nurses will reduce numbers of infants' night wakes and parents' perceptions of infant sleep difficulties compared with parents who receive a group teaching about infant safety and follow-up phone calls provided by Public Health Nurses. Results from this study will help the investigators improve their practice when assisting parents and infants with sleep problems.
The investigators will examine whether sleep problems in children with autism spectrum disorder (ASD) are related to alterations in the production of melatonin (MT), a hormone that plays an important role in regulating sleep-wake cycle. Children with ASD experience high rates of sleep disturbances that potentially contribute to problems with thinking and behavior. It is unclear if changes in MT production cause sleep problems in children with ASD. MT is frequently used to treat these sleep problems; however, it has not been well established whether MT is an effective treatment. Our hypotheses concerning MT is children with ASD and sleep problems will have a delayed sleep-wake cycle and/or decreased MT production. This study will compare children diagnosed with ASD to "healthy" control children with no ASD diagnosis. All subjects will be recruited from one of three sites: Baylor College of Medicine, Oregon Health & Science University and Columbia University. The investigators will use a standardized questionnaire to determine whether the child has sleep problems. The investigators will measure MT levels in saliva in ASD children with sleep problems and in a group of control children without sleep problems. Total 24-hour MT production will be determined from urine samples in these same two groups.
Sleep problems can lead to a bad quality of life and a raise of morbidity, also in dialysis patients. Sleep problems can be caused by a disturbance of circadian rhythms in our body. For a good regulation of these circadian rhythms a uniform external synchronisation is necessary. This is the synchronisation of the biological clock of our body by light and other influences. In case of a disturbance of the external synchronisation, due to for example naps during the day or wake periods at night, internal rhythms can be unlinked. As a result a weakened melatonin rhythm and a problematic sleep-wake cycle can be observed. Most dialysis patients have sleep problems. Their sleep latency is prolonged. They often take a nap during the day and their sleep efficiency is poor. There has only been one study on the melatonin rhythm of dialysis patients. The conclusion of this study was that the melatonin rhythm of dialysis patients is weakened and disturbed, probably caused by renal insufficiency. In this study no link was made between melatonin rhythm and the nature and severity of possible sleep problems. In different studies with non-dialysis patients and a disturbed melatonin rhythm, exogenous melatonin at the right time leads to a recovery of the normal rhythm and the normal biological clock and a better quality of life. The aim is to research the endogenous melatonin rhythm and to improve sleep problems of hemodialysis patients with a placebo-controlled study with exogenous melatonin. Next to this a substudy is performed, in which the effect of the change of daytime to nocturnal in hospital hemodialysis on sleep and melatonin is researched.

Sleep and discipline problems are the most common problems for parents of young children (ages 2 to 5 years old) and are the two concerns with the strongest relations to future child behavior problems. The Parenting Matters program combines treatment booklets and telephone support to help parents deal with sleep or discipline problems. Parents with concerns and who are interested in the study are identified during a visit to their family physician. We, the investigators at the University of Western Ontario, expect that parents receiving treatment booklets, along with usual care by their family physician, will have greater reductions in their child's sleep or discipline problems, improved parenting practices, and greater reductions in child behaviour problems after receiving the Parenting Matters intervention, compared to parents receiving usual medical care.
