Filter by:In this study, the investigator plans a randomized trial of melatonin versus placebo post acute pediatric concussion. The investigator hypothesizes that patients with acute concussions managed with melatonin will have improved sleep, decreased depressive symptoms, decreased risk of prolonged concussion symptoms and faster resolution of concussion symptoms.
The study aims: - to observe a population particularly exposed by the past to brain trauma and concussion: Motorsport Pilots who are retired from a professional practice of motor sport; - to report results of their neuro-cognitive evaluations, - to determine if specific profiles emerge. - to evaluate potential consequences of these traumas' history at a cerebral, physical and psychological level. - to evaluate the contribution of the various examinations performed as part of a concussion assessment in routine care (eye-tracking, brain imaging, Neuropsychological Assessment).
Mental health problems frequently complicate recovery from mild traumatic brain injury (mTBI) but are under-recognized and under-treated. Our research program aims to identify evidence-based strategies for closing this knowledge-practice gap. Building on a successful pilot trial, the reseachers will evaluate the effectiveness of a clinical practice guideline implementation tool designed to support proactive management of mental health complications after mTBI in primary care.
Approximately 1.9 million youth sustain a concussion each year, and up to 30% experience persistent post-concussive symptoms (PPCS) such as headache, dizziness, and difficulty focusing that continue for weeks or months. PPCS results in greater utilization of sub-specialty care and can impact immediate and long-term social development, cognitive function and academic success. Previous recommendations for treating PPCS have focused on cognitive and physical rest, but more recently guidelines have shifted based on new research suggesting the benefit of rehabilitative exercise for PPCS. The rationale behind using exercise to treat youth with concussion is that gradually increasing physical activity facilitates return to full function. Rehabilitative exercise has since become one of the most common approaches to treating youth with PPCS, but access is challenging since most programs require weekly centralized visits with a concussion specialist. To bridge this gap, the investigators developed a telehealth-delivered approach to treat PPCS, utilizing physical activity trackers (Fitbits) and weekly video conferences with trained research staff. They then conducted a series of pilot studies with this approach, finding excellent feasibility, acceptability, and evidence for more rapid declines in concussive symptoms compared to controls. The investigators also found preliminary evidence that mechanisms behind this intervention may stem from both physiologic processes due to increased moderate-to-vigorous physical activity (MVPA) and psychologic processes such as reducing fear- avoidance of concussive symptoms. They now propose a fully-powered randomized controlled trial (RCT) to asses the efficacy of the "Mobile Subthreshold Exercise Program" (M-STEP) for treating youth with PPCS.
This study will evaluate the practicality (i.e. acceptability to stakeholders; outcome battery feasibility; recruitment, retention, and adherence rates) and the preliminary effect of a cognitive strategy training intervention in adults with post-concussive syndrome.
The purpose of this pilot study is to better understand the effects of chronic cannabis (THC) use on the neural responses to subconcussive head impacts, as a form of repetitive soccer headings. The study is designed to identify the physiological changes of cannabis using cohort (THC) and compare it to a nonusing cohort in order to see if the responses to 20 controlled bouts of soccer headings are exacerbated by the chronic cannabis use, diminished to less of a response, or unchanged, through an array of neurologic measures, including cognitive function, ocolar-motor function, autonomic function, and blood biomarkers. The hypothesis is that repetitive subconcussive head impacts will impair cognitive function in worse memory, attention span, and visual and verbal problem solving; this impairment will be greater in the chronic cannabis use groups than non-using group. The blood and salivary biomarkers neurofilament light (NFL) and glial fibrillary acidic protein (GFAP) will be measured in plasma, with the hypothesis that repetitive subconcussive head impacts will significantly increase plasma NFL and GFAP level at 24 hours-post heading and decrease by 72 hours-post heading, while remaining undetectable at 2 hours-post heading; the chronic cannabis use groups will see more severe effects on ocular-motor function than the non-using group. The study aims to determine the differences in acute effects of subconcussive head impacts on eye movement, attention, and language function between chronic cannabis use subjects and non-using subjects by evaluating ocular-motor function with near point of convergence and King-Devick tests. The hypothesis is that repetitive subconcussive head impacts will significantly increase impairments of eye movements, attention, and language function, as well as near point of convergence; the chronic cannabis use groups will see more severe effects on hampered ocular-motor function than the non-using group. Lastly, there is a cold pressor test to assess autonomic nerve function, with the hypothesis that repetitive subconcussive head impacts will decrease autonomic nerve function in chronic cannabis use patients to a greater degree than non-using subjects.
Traumatic brain injury (TBI) is defined as a structural alteration of brain function caused by external causes, where mild traumatic brain injury (mTBI) represents approximately 80% of all TBI, and although its prognosis is relatively good, it represents a significant cost to the system due to the need to perform a cranial computed tomography (CT) scan, a test of high economic value and not without risks such as irradiation, especially important and dangerous in the pediatric age. The investigators aim to set-up a point of-care (POC) device to validate a biomarker (H-FABP) able to diagnose the presence of brain damage in children and adults with mTBI at trauma and paediatric Emergency Departments using a blood sample, in order to save resources and avoid subjecting patients to a potentially damaging imaging test. But also, to assess whether the incorporation of new biomarkers improves the prediction of brain damage that can be done with H-FABP. For that, the investigators will recruit a 400 patients' cohort with blood samples using the available POC device for H-FABP biomarker.
Using the Consolidated Framework for Implementation Research, as our overarching conceptual framework, this translational 2 ½ year pragmatic RCT uses a clustered, stepped wedge design to test the effectiveness of a school-based (unit of analysis) implementation strategy (project intervention) called RISE (Return to Learn Implementation bundle for schools) on evidence-based practice (RTL protocol implementation; main outcome) and student outcomes (i.e., days to RTL start after diagnosis) after youth concussion. The central hypothesis is that schools in the intervention condition receiving the RISE implementation bundle (toolkit plus school support) will have more complete and sustainable RTL protocols, and better student outcomes compared to schools in control condition who receive only written RTL protocol information. As rural and low SES schools are particularly likely to struggle to implement RTL protocols,19,25 we specifically examine RISE implementation and barriers to implementation related to school demographic characteristics related to health equity. The school characteristics we examine are rurality, primary language, racial and ethnic mix, and free/reduced-cost lunch.
Up to 28% of undergraduate college students report a suspected history of traumatic brain injury. Following traumatic brain injury, college students fail and repeat more courses and have lower grade point averages. Further complicating this problem may be the fact that college students lack knowledge of traumatic brain injury definition, its associated symptoms, and individuals involved in post-injury management. In this project, the investigators propose to compare the use of an established treatment model (i.e., the Dynamic Coaching Model) to a novel protocol (i.e., the Apprenticeship Approach) that includes explicit instruction about traumatic brain injury in college students with this population. The investigators will use a group comparison design to examine the efficacy of this instructional component. This work incorporates findings from educational psychology and speech-language pathology (e.g., the included instructional materials adhere to the principles of adult learning). As such, this work will advance the field's basic understanding of currently recommended treatment components and will systematically examine the effects of incorporating explicit instruction into an existing treatment model.
Primary Aim: Compare physiological (e.g., heart rate) and clinical responses (e.g., symptom provocation) of adolescent and adult athletes (14-35 years of age) completing either a structured treadmill running or a dynamic aerobic exertion protocol during the subacute phase of sport-related concussion recovery (3-30 days after injury). Secondary Aim: Examine potential effects of clinically-relevant factors that influence symptom responses to controlled aerobic exertion, such as age, physical activity patterns, motion sensitivities, psychological responses to injury, and sleep quality, among subjects completing controlled aerobic and dynamic exertion following sport-related concussion
