Filter by:Mania is a serious condition. Symptoms of mania include decreased sleep, increased energy, changes in mood, thinking, and behavior. Dark therapy, which involves placing patients in a dark room for 14 hours overnight, can effectively treat mania, but is not practical. Dark therapy is also unpleasant. However, similar effects on the brain can be created from blocking only blue light with glasses. This preserves the wearer's ability to see and move safely. A trial of blue-blocking glasses for mania in Norway produced dramatic improvements in manic symptoms within three days of hospitalization. Mania both disrupts the sleep-wake cycle and is triggered by short and interrupted sleep. Examples of triggers include shift work and travel across time zones. Therefore, mania involves the "day-night" clock in the brain. The rhythm of the brain's clock is set by special sensors in the eye that identify daytime from blue light. If light does not include this blue spectrum, this informs the brain it is nighttime. In spite of the obvious potential of blue blocking glasses for mania, there has been no confirmatory study of this simple treatment in the five years since the initial Norwegian trial. Without a second study, this treatment will not find its way into routine clinical care. The investigators will conduct a randomized controlled trial of blue-blocking glasses for mania in hospitalized patients. The investigators will also assess activity, sleep, and saliva melatonin (a hormone secreted in the brain at night) to see how this treatment works. If our trial confirms that blue-blocking glasses are effective, this treatment could help those suffering with mania return to their life more quickly. Medications for mania can also cause serious side-effects and having glasses as a treatment option might also reduce the amount of medicine needed to get well. Blue-blocking glasses could be a low-cost non-medication treatment. The investigators will look at how they could put this treatment into practice as part of everyday care.
This study is a mechanistic clinical trial designed to investigate the effects of the circadian system and sleep on non-dipping blood pressure (BP) in people with hypertension (HTN).
This Minimal Risk study is designed to evaluate the ability of the Celero ingestible Vitals Monitoring Pill (i.e., VM Pill) to measure respiration from within the gastrointestinal tract, in addition to performing an exploratory comparative analysis of data collected by the VM Pill and data collected from clinical monitoring sensors as part of polysomnography.
The aim of this study is to determine the effect of exercise on quality of life, sleep quality and anxiety in patients with prediabetes.
Dementia caused by Alzheimer's disease affects approximately 5.6 million adults over age 65, with costs expected to rise from $307 billion to $1.5 trillion over the next 30 years. Behavioral interventions have shown promise for mitigating neurodegeneration and cognitive impairments. Sleep is a modifiable health behavior that is critical for cognition and deteriorates with advancing age and Alzheimer's disease. Thus, it is a priority to examine whether improving sleep modifies Alzheimer's disease pathophysiology and cognitive function. Extant research suggests that deeper, more consolidated sleep is positively associated with memory and executive functions and networks that underlie these processes. Preliminary studies confirm that time-in-bed restriction interventions increase sleep efficiency and non-rapid eye movement slow-wave activity (SWA) and suggest that increases in SWA are associated with improved cognitive function. SWA reflects synaptic downscaling predominantly among prefrontal connections. Downscaling of prefrontal connections with the hippocampus during sleep may help to preserve the long-range connections that support memory and cognitive function. In pre-clinical Alzheimer's disease, hyperactivation of the hippocampus is thought to be excitotoxic and is shown to leave neurons vulnerable to further amyloid deposition. Synaptic downscaling through SWA may mitigate the progression of Alzheimer's disease through these pathways. The proposed study will behaviorally increase sleep depth (SWA) through four weeks of time-in-bed restriction in older adults characterized on amyloid deposition and multiple factors associated with Alzheimer's disease risk. This study will examine whether behaviorally enhanced SWA reduces hippocampal hyperactivation, leading to improved task-related prefrontal-hippocampal connectivity, plasma amyloid levels, and cognitive function. This research addresses whether a simple, feasible, and scalable behavioral sleep intervention improves functional neuroimaging indices of excitotoxicity, Alzheimer's pathophysiology, and cognitive performance.
The aim of this study is to advance understanding of behavioural risk factors for cardiovascular disease and type 2 diabetes in Singapore.
There are few devices currently on the market claiming to improve sleep. This study will investigate the efficacy of phototherapy on improving sleep, in the form of a wearable neck device used at night.
The goal of this study is to determine the feasibility in continuing to explore NextSense's ear-EEG device (EEGBud) and Ellcie Healthy glasses as wireless, wearable alternatives to the expense, discomfort, and burden in conventional surface electrodes and hardwired signal amplification for assessing consciousness states such as wake from sleep.
Pain of the sacrococcygeal region is called coccygodynia This painful clinical picture, which causes a decrease in the quality of life, also causes disability. Coccycodynia has been associated with hysteria, neurosis, and depression. In some studies, it has been reported that it should be evaluated in somatization in coccygodynia. There are a few studies examining the relationship between coccygodynia and psychiatric disorders.There is no study in the literature examining coccygodynia and sleep. There may be a relationship between pelvic floor muscle spasm in the etiology of coccygodynia and sleep quality. In this study, it is aimed to investigate the relationship between disability severity and anxiety, depression and sleep quality in patients with coccygodynia.
This study aims to investigate the effect of a 15-minute meditation practice on sleep architecture and high-frequency Heart Rate Variability (HF-HRV), as well as cognitive performance after both a well-rested and sleep-deprived night.
