The aim of our study is the analysis of sleep phases and quality as well as the detection of respiratory pauses in subjects with cognitive disorder. To assess whether sleep quality is associated with the blood-brain barrier and Alzheimer's disease, which may be indicative of an early, non-invasively measurable change in brain activity in the early stages of Alzheimer's disease.
This study attempts to replicate the findings published in Nature Medicine by Nation and colleagues (2019). By using a large observational cohort (DZNE - Longitudinal Cognitive Impairment and Dementia Study; DELCODE) consisting of cognitively healthy individuals, individuals with subjective cognitive decline, mild cognitive impairment, and dementia due to Alzheimer's disease, an association between the blood-brain barrier and cognitive dysfunction is investigated. The integrity...
Sleep is critical to human health, but insufficient and disrupted sleep caused by sleep apnea are common and have a major impact on brain health. However, there is still much that is not known about how sleep apnea damages the brain and what can be done to fix this. The Brain Changes in Sleep Apnea Study will look at the brain health of people with severe sleep apnea both before and after 4 months of treatment with a CPAP machine. Pre- and post-CPAP treatment, 80 participants w...
To further understanding of the relationship between sleep and memory the investigators will address and attempt to answer three questions, (1) how memories evolve across wake and sleep, (2) how different aspects of this memory evolution are reflected both behaviorally and in the EEG signal, and (3) what stages and features of sleep affect memory evolution. Together, these studies will provide a greater breadth and depth of knowledge concerning sleep's role in memory consolidat...
Adolescence is characterized by major transitions in sleep and circadian rhythm. This rapid pivotal period increases the risks of sleep debt and poor sleep quality, leading to pronounced diurnal fatigue and drowsiness . Some adolescent's populations are more vulnerable than others to poor sleep. Obesity and elite sports involvement are two factors that have been distinctly associated with disturbed sleep. Several studies show that obesity was associated with a decrease in sleep...
Sleep problems are common in the United States (US) adult population (>50 million), and have a negative impact on quality of life, productivity, and healthcare. A major obstacle to understanding how the brain is involved in human sleep disorders has been the lack of recordings of human brain function, from inside the brain, during the known sleep states.
Quality of sleep is profoundly affected in patients with hypercapnic respiratory failure and restrictive disorders, with a decrease in rapid eye movement (REM) and slow wave sleep, and an increase in sleep fragmentation. Assisted ventilation aims at improving blood gases, but may also have a favorable impact on sleep structure. The investigators reviewed polysomnographic and blood gas data obtained between 1987 and 2008 in 95 patients with restrictive pulmonary disorders, befor...
The purpose of this study is to evaluate the blood brain barrier in the striatum of patients that have other types of movement disorders compared to patients with Parkinson's Disease that are receiving similar treatment, to determine if a there is a disruption of the blood brain barrier in patients with Parkinson's Disease.
Sleep exerts a dual effect on learning: on the one hand, good sleep quality allows good daytime aptitudes leading to knowledge acquisition. On the other hand, sleep after learning is necessary for knowledge consolidation. A key role of sleep has clearly been demonstrated in memory consolidation in adults. Sleep leads to strengthen memory by promoting brain plasticity. Surprisingly, sleep influence on learning stabilization has scarcely been studied during childhood and in child...
This is a study to determine if Magnetic Resonance Imaging (MRI) techniques can detect early changes in white matter (in the brain) and the blood-brain barrier resulting from radiation therapy.
Several studies have demonstrated an association between sleep disorders such as insomnia and nightmares to suicidal ideations and behaviors. Nevertheless, some of these studies are methodologically questionable especially in the exploration of sleep disorders. Furthermore, confounding factors such as depressive symptomatology are not controlled and the measurement of suicidal behavior has often been taken into account as a historical measure, not as a current event, which int...
The purpose of this study is to evaluate the safety and efficacy of the ExAblate® Model 4000 Type 2.0 system as a tool to open the blood-brain barrier (BBB) in patients with probable Alzheimer's Disease (AD).
Sleep disorders and disturbances are mostly underestimated in clinical practice. Moreover, this problem is generally neglected by the pregnant themselves. Today, it is important to underline any problem that may have an affect to improve the quality of life during pregnancy. This study assesses the sleep quality, insomnia patterns and obstructive sleep apnea in the second and third trimesters of pregnancy.
Sleep disturbance is prevalent in chronic dialysis patients and there is a negative correlation between the quality of life and overall survival and sleep disturbance in them. Cognitive-behavioral therapy is an effective behavioral therapy for insomnia clinically. In previous studies, cognitive-behavioral therapy can redress anxiety in chronic hemodialysis patients. This study tries to elucidate its therapeutic effect on the sleep disturbance in chronic peritoneal dialysis pati...
Brain health and cognitive functioning can be affected by aging. Exercise is a potentially effective method for promoting "successful brain aging" by improving cardiovascular fitness, brain function and possibly sleep quality. This project will measure the effects of exercise on brain health and attempt to develop a better way to track brain health, by measuring brain activity during sleep.
This study will explore the relationship between sleep, learning, cognition, mood and behaviour in children with Tic Disorders (Tourette Syndrome and Chronic Tic Disorder) compared to typically developing peers.
The purpose of this study is to evaluate the safety and efficacy of the ExAblate Model 4000 Type 2.0 System as a tool to disrupt the blood-brain barrier (BBB) in patients with probable Alzheimer's Disease (AD).
This pilot research trial studies blood brain barrier differences in patients with brain tumors undergoing surgery. Studying samples of tissue and blood from patients with brain tumors in the laboratory may help doctors to understand how well drugs get into different parts of a brain tumor. This may help them to determine which types of drugs may be best for treating brain tumors.
The purpose of this prospective, participant-blinded trial is to determine the changes in sleep architecture in a cohort of subjects who have undergone deep brain stimulation (DBS) surgery for treatment of movement disorders such as moderate to advanced Parkinson's disease (PD), tremor, or dystonia. Our preliminary observational data suggest that unilateral subthalamic nucleus (STN) DBS improves subjective sleep quality in PD patients 6 months after the procedure. The cause o...
A 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 com...
The purpose of this study is to find out a serum marker for the evaluation of blood brain barrier damage based on animal experiments and investigate the effect of NBO（Normobaric hyperoxia）on blood brain barrier in the acute ischemic stroke patients who received r-tPA thrombolytic therapy.
Loss of slow wave sleep is common in mild cognitive impairment (MCI) and Alzheimer's disease, and is thought to worsen thinking, memory and brain degeneration. Initial studies suggest that correction of sleep deterioration may slow the progression of brain damage in mild cognitive impairment, and might be able to stop the development of Alzheimer's disease. Transcranial alternating current stimulation (tACS) uses electrodes to deliver very small amounts of electricity through t...
AVI-4020 Injection, a phosphorodiamidate Morpholino oligomer (PMO), was found to cross the blood-brain barrier during a study of patients with presumptive West Nile virus disease. AVI-4065, which was designed to target HCV, is also a PMO; its ability to cross the blood-brain barrier is unknown. In this study, a single dose of AVI-4065 will be subcutaneously injected, and samples collected to determine if this drug crosses the blood-brain barrier. If it does, then additional ...
Age-related sleep changes and common sleep disorders like obstructive sleep apnea (OSA) may increase amyloid burden and represent risk factors for cognitive decline in the elderly. We will directly interrogate the brain using a 2-night nocturnal polysomnography (NPSG) and amyloid deposition using C-PiB PET/MR both at baseline and at the 24-month follow-up. This study has the potential to identify the mechanisms by which age-related sleep changes contribute to AD neurodegenerati...
About 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 syst...
