Filter by:The goal of this observational study is to investigate concussions and contact sports practices in REM sleep behaviour disorder (RBD). The main questions it aims to answer are: - What is the proportion of patients with RBD that have a history of concussions or exposure to contact sports? - Is this proportion higher to that in control patients without a diagnosis of RBD? Participants will undergo an interview with a sleep medicine specialist to answer questions about history of concussions and contact sports practices. Researchers will compare an RBD group and a control group (without RBD) to see if the proportion of concussions and exposure to contact sports differ.
There is a lot of research on how to treat people with sport-related concussion. There has not been a lot of research on the treatment of injured workers with concussion. An exercise program has been developed for people with sport-related concussion. It is suspected that this program may be helpful for injured workers with concussion too. This study will test the effect of this exercise in injured workers with concussion.
The goal of this clinical trial is to compare the effects of acute aerobic exercise at two different intensities on psychological measures, symptomology, and time to symptom free in collegiate student athletes with concussion. The main questions it aims to answer are: - Does prescribed, acute aerobic exercise influence measures of pain related fear, anxiety, depression, symptoms, and recovery time? - Does the intensity of the exercise prescription also influence the aforementioned outcomes? Participants will be randomly assigned into either a light intensity or moderate intensity aerobic exercise (treadmill walking) group. They will initiate the exercise protocol 48 hours following their concussion diagnosis, and complete exercise sessions 5 times per week until they report symptom-free. Researchers will compare the light intensity group to the moderate intensity group to see if intensity of exercise influences psychological measures of pain related fear, anxiety, depression, symptomology, and time to symptom-free.
The proposed study aims to compare concussion recovery in those supplementing creatine and those not supplementing creatine. Specific aim 1: To compare number of days until asymptomatic between those taking creatine vs. those not taking creatine following a concussion. Hypothesis: The investigators hypothesize that individuals taking creatine will become asymptomatic sooner than those not taking creatine.Specific aim 2: To compare typical concussion assessment scores (i.e., symptom score, mental status, neurocognition, balance, motor coordination, and visual performance) between those taking creatine vs those not taking creatine following a concussion once asymptomatic.Hypothesis: The investigators hypothesize that individuals taking creatine will have better symptom scores, balance, mental status, and neurocognition assessment scores than those not taking creatine once asymptomatic. The investigators will calculate descriptive statistics for all demographic, days to asymptomatic, and concussion assessments. For specific aim 1, The investigators will calculate a t-test to determine if days to asymptomatic differed in those taking creatine vs. those not taking creatine. For specific aim 2, the investigators will calculate t-tests with Bonferonni corrections to determine if concussion assessment scores (Sport Concussion Office Assessment Tool-6 assessments, CNS Vital Signs, visual assessment) differed in those taking creatine vs. those not taking creatine.
Concussions in sports are a major public health problem because of their frequency, and are often underdiagnosed because of an unspecific clinical picture or sometimes masked by the concussion itself. Support data has been constantly evolving in recent years, including the last publication of the Berlin Consensus in 2016 specifying support in the field. However, to date, there is no tool to predict the severity of a concussion or to predict when it will return to play objectively and reliably. Brain MRI done after the head injury is most often normal. However, previous studies agree that there is a persistent electrophysiologic disturbance several weeks after the injury, and the specific pathophysiology of white matter changes after a head injury remains controversial. Diffusion tensor imaging (DTI), in addition to morphological sequences, is capable of assessing white matter microstructure and fibrous tract integrity or not. Several parameters, such as the seemingly normal white matter fractional anisotropy (FA) coefficient, the mean diffusivity and the radial diffusivity, may be altered in the aftermath of a concussion, indicating axonal damage not visible on conventional MRI sequences. Previous studies have evaluated these parameters with sometimes contradictory results: some have found an increase in AF in specific regions such as the cortico-spinal tract and the corpus callosum, others have found a decrease in AF. So far, assessment of a player's condition on and off the field after a head injury has been based on clinical criteria alone, sometimes far too subjective. The player may choose to mask their symptoms to allow them to return to the game faster, or feign more than they have. Once pathologies such as bone fractures or intracranial hematomas are ruled out by conventional imaging, there is no longer any tool for a more accurate diagnosis of possible microstructural alterations of brain tissue and for monitoring of the patient. The advent of new MRI techniques such as diffusion imaging, and particularly diffusion tensor imaging (DTI), is a promising tool to better understand white matter involvement in diffuse axonal lesions.
To date, there is no validated pharmacotherapy for olfactory disorders. Interestingly, olfactory training - the intentional exposure to odorants for the purposes of retraining the sense of smell - has shown success with as many as 28% of subjects over the course of 12 weeks.
The goal of this study is to investigate a new treatment for chronic symptoms after concussion or mild traumatic brain injury in people aged 18-65 years old. Chronic symptoms could include dizziness, headache, fatigue, brain fog, memory difficulty, sleep disruption, irritability, or anxiety that occurred or worsened after the injury. These symptoms can interfere with daily functioning, causing difficulty returning to physical activity, work, or school. Previous concussion therapies have not been personalized nor involved direct treatments to the brain itself. The treatment being tested in the present study is a noninvasive, personalized form of brain stimulation, called transcranial magnetic stimulation (TMS). The investigators intend to answer the questions: 1. Does personalized TMS improve brain connectivity after concussion? 2. Does personalized TMS improve avoidance behaviors and chronic concussive symptoms? 3. Do the improvements last up to 2 months post-treatment? 4. Are there predictors of treatment response, or who might respond the best? Participants will undergo 14 total visits to University of California Los Angeles (UCLA): 1. One for the baseline symptom assessments and magnetic resonance imaging (MRI) 2. Ten for TMS administration 3. Three for post-treatment symptom assessments and MRIs Participants will have a 66% chance of being assigned to an active TMS group and 33% chance of being assigned to a sham, or inactive, TMS group. The difference is that the active TMS is more likely to cause functional changes in the brain than the inactive TMS.
More than 1 million U.S. youth sustain a concussion each year, and up to 30% report persistent post-concussive symptoms (PPCS) lasting 1 month or more. PPCS can interfere with normal adolescent development, resulting in issues with socioemotional dysfunction and even school failure. However, few evidence based treatments are available for youth with PPCS. The investigators conducted extensive work adapting a collaborative care framework for youth with PPCS, combining concussion-focused cognitive behavioral therapy (cf-CBT), parent skills training (PST) and care management (CM) to create a wraparound treatment for youth with PPCS that can be delivered either in-person or virtually. They completed an R01-funded randomized controlled trial with this approach, finding effectiveness for youth with PPCS, with improvements in concussive symptoms and quality of life at one year, and 60% of participants completing the intervention entirely virtually. Of note, this intervention is unique in that two of the components are focused on parents or parents and youth together (PST, CM), and only one of the components (cf-CBT) is solely youth focused. The investigators now propose to optimize and refine this approach, conducting a high efficiency MOST (multiphase optimization strategy) trial to assess the contribution of each of the three components (cf-CBT, PST and CM) to effectiveness, thereby enabling streamlining of the intervention to only include active components. The analysis will be factorial, with three intervention components and two levels of each (present or absent), resulting in 8 treatment pathways. The benefit of the MOST approach is that it combines all youth who receive a component, allowing assessment of all treatment components with only a modest sample size. The study will recruit 374 youth with PPCS, randomizing them to one of 8 treatment groups. Youth and/or parents will attend treatment sessions via video conferencing software over three months, and complete surveys regarding primary outcomes (concussive symptoms and health-related quality of life) and secondary outcomes (sleep, pain, mood and parental distress) at 6 weeks, and 3, 6 and 12 months. Potential mediators and moderators will also be assessed to allow for future tailoring and refinement. At the completion of this study, the investigators will have generated a completely optimized and refined intervention for youth with PPCS ready for large scale implementation and dissemination.
Mild traumatic brain injury (mTBI), also referred to as concussions, affect millions of people around the world and can cause harmful long term effects. Unfortunately, concussions can be hard to diagnose and many people have lasting post-concussion symptoms such as headaches, difficulty concentrating, and light sensitivity. Recent studies have shown that advanced magnetic resonance imaging (MRI) techniques can identify subtle brain changes caused by a concussion. This study aims to track concussions over time measuring MRI brain scans and post-concussion symptoms to gain a better understand how the brain is affected in comparison to symptoms.
Upwards of 3.8 million concussions occur annually in the United States. Driving is a highly complicated activity that requires visual, motor, and cognitive skills, which are commonly impaired after concussion. Yet, the time course of post-concussion driving impairment has not been characterized. There is a critical need to 1) determine when concussed individuals should return to driving and 2) identify the key concussion assessment predictors of readiness to return to driving. In the absence of formal recommendations, impaired concussed drivers are at risk to themselves and others on the road. The first specific aim is to compare simulated driving between concussed individuals and non-concussed yoked matched controls across five longitudinal timepoints (pre-injury baseline, day 2, day 4, asymptomatic, and unrestricted medical clearance) and daily naturalistic driving from day 2 to day 9. Driving recommendations must be appropriate and necessitated by concussion impairments, since excessively strict recommendations wrongfully strip concussed patients of their independence and may dissuade individuals from seeking medical care. The second specific aim is to identify widely used concussion assessment outcomes that predict simulated driving performance among concussed individuals throughout concussion recovery. To address these aims, 100 concussed and 100 yoked matched control young adult college athletes will complete a simulated driving assessment and a robust concussion assessment battery at pre-injury baseline, day 2, day 4, asymptomatic, and unrestricted medical clearance. Naturalistic driving (measured with in-car global positioning systems) will be captured from day 2 to day 9 (7 days total). This study will determine the acute and subacute time course of post-concussion driving impairment and determine key predictors of post-concussion driving performance. Results from this innovative approach will have a broad and positive impact that will improve the safety of both concussed individuals and the general population, guide the practices of health professionals, inform the future work of researchers, and substantiate the work of policy-makers by providing evidence-based recommendations for managing post-concussion driving.
