Active clinical trials for "Brain Concussion"

The objective of this study is to investigate the treatment effect of repetitive transcranial magnetic stimulation in patients with a history of both persistent post-traumatic headache and post-concussion symptoms. In this double-blind, sham-controlled, concealed allocation, randomized clinical trial, 20 patients aged 18-65 yrs will be recruited from the Calgary Brain Injury Program (CBIP) and the Calgary Headache Assessment and Management Program (CHAMP) / Calgary Chronic Pain Centre, Calgary, Alberta, Canada. Patients will engage in a two-week rTMS treatment protocol (10 treatments) and will be followed for 6 months after therapy.

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 complaints, mood disturbance, and lower quality of life. Despite the identification of sleep disturbance as a problem associated with slow recovery, there are very few treatment options. Cognitive-behavioural therapy for insomnia (CBT-I) has shown promise in children and adolescents as an effective treatment for sleep disturbance, although it has yet to be applied to the adolescent mTBI population who also present with sleep problems. The objective of this study is to examine the treatment of sleep disturbance using cognitive-behavioural therapy for insomnia (CBT-I) in those adolescents who have a protracted recovery from their mTBI. This represents a novel treatment option for this patient population and is anticipated to improve outcomes and quality of life.

Mild traumatic brain injury (mTBI) is among the most common injuries sustained by Veterans of Operations Enduring and Iraqi Freedom. It is also highly co-morbid with mental health conditions, such as post-traumatic stress disorder and depression. While mTBI alone is not typically thought to cause lasting deficits in personal functioning or cognitive abilities, Veterans with a history of mTBI nonetheless report chronic psychological distress, as well as subjective difficulties with attention, concentration, poor frustration tolerance, and decision-making. Although current clinical practice guidelines for mTBI emphasize primary care-based symptom management, there are presently no evidence-based interventions to treat mental health symptoms in this setting. This research proposal therefore seeks to adapt and pilot test a brief, primary care-based intervention (E-PST) to reduce psychological distress in Veterans with mTBI by augmenting problem-solving skills, and helping them to develop specific cognitive and behavioral skills to improve upon their self-reported cognitive inefficiencies. The investigators hypothesize that Veterans who complete E-PST will report improvements in psychological distress compared to participants in the control condition.

Mild traumatic brain injury (mTBI), also known as concussion, is of great concern in the youth population, with incidences of injury steadily increasing within the past few years. Current Canadian estimates have indicated that the total rate of concussions per 100,000 increased from 467 to 754 for boys and from 209 to 441 for girls from 2003-2010. As defined by the recent Zurich Consensus statement, concussion is a pathophysiological injury induced by biomechanical forces, which can be caused by impact to the head, neck or body. In 10-20% of youth, concussion symptoms persist in the weeks, months or even years following the injury. Consequently, youth with persistent concussion symptoms are unable to fully participate in the meaningful activities (e.g. attending school, engaging with friends and community) they did prior to the injury and experience a reduced quality of life. Persistent concussion symptoms in youth requires an approach that directly addresses the rumination and attention to distressful thoughts about their functional performance, while still promoting appropriate levels of physical and cognitive demands. Targeting these constructs may shift the focus away from symptoms, while building self-efficacy and enhancing participation in daily activities. Mindfulness-based yoga (MBY) is a mind-body intervention that uses physical yoga poses, purposeful breathing techniques and a focus on being in the present moment. MBY encourages participants to develop moment-to-moment awareness of physical sensations, emotions, and thoughts, and promotes the cultivation of non-judgemental and accepting relationships to personal experiences. In chronic pain, fibromyalgia, mental health and now TBI populations, MBY has demonstrated benefits in physical (i.e. increased muscle strength, endurance), psychological (i.e. decreased stress, increased self-efficacy), cognitive (i.e. increased concentration) and social (i.e. emotional regulation, improved mood) domains. Although mindfulness based yoga has been validated as a form of rehabilitation in the adult population, its applicability for youth with persistent concussion symptoms has yet to be explored. Understanding the impact of a MBY intervention on this population may enhance management of persistent symptoms and ultimately, participation in meaningful activities. In addition to the functional sequelae that ensue following this injury, concussion in both the acute and persistent phases is being recognized as a neurophysiological injury. Traditional methods of assessment following concussion place emphasis on subjective self-report and administration of neuropsychological batteries. These assessments are used in an effort to return the youth to activity (i.e school, sport). However, these methods can be unreliable as youth have a high incentive to return to play and neurocognitive resolution does not necessarily equate to pre-injury function. To augment these measures, an objective indicator of neurophysiological stress is needed. Heart rate variability (HRV) is an objective, neurophysiological indicator of autonomic nervous system functioning. HRV is quantified by measuring the time intervals between heartbeats. Increased variability in heart rate (i.e. increased HRV) is seen as healthy neurophysiological function, demonstrating an individual's ability to adapt and be flexible to the demands of the environment. Conversely, decreased HRV is demonstrative of an individual's reduced ability to respond flexibly to their environment. Investigating the impact of persistent concussion symptoms on HRV has the potential to enhance our understanding of autonomic nervous system functioning in the chronic phases of this injury for an understudied population. The specific objectives are to: (1) adapt the MBY intervention protocol to suit the unique needs of youth with mTBI (i.e. safety, fatigue), (2) collect data on the impact of MBY on HRV, self-efficacy and participation, (3) describe changes in HRV, self-efficacy and participation associated with MBY across pre-intervention, post-intervention and 3 months following intervention, (4) identify if post concussion symptoms change (i.e. increase or decrease) following MBY and (5) identify if changes in post concussion symptoms occur with changes in HRV, self-efficacy and participation.

The goal of this observational study is to test if a biosensor can accurately measure a blood biomarker in adult patients presenting to the emergency department with concussion. The main questions it aims to answer are: Does the biosensor measure the blood biomarker of interest with the same accuracy as the current gold-standard assay technique? Do relationships exist between blood biomarker measurements from the biosensor and any psychological or physical symptoms of concussion? Participants will be asked to provide blood samples at initial visit and 2-, 6-, and 12-weeks after injury while completing questionnaires at each visit, along with a brief (2 min) daily symptom inventory. Researchers will compare the concussion group to a muscle/skeletal injury group to see if measurements from the biosensor are exclusive to concussion.

This research study will evaluate a standalone software application and is designed to standardize and validate new neurocognitive screening testing for children aged 6 through 11, and adolescents and adults ages 12 through 75. The purpose of this study is to evaluate recently developed computerized tasks sensitive to changes in neurocognitive performance after a concussion. These tests were designed to help measure the effects of concussion on cognitive processes (e.g., memory, attention, brain speed) and visual functioning.

Concussions are defined as a complex pathophysiological process affecting the brain, induced by traumatic biomechanical forces. Currently the standard of care in the treatment for concussions is cognitive and physical rest until symptoms resolve with a graduated return to activity. High dose omega-3 fatty acids have shown to have anti-inflammatory, anti-oxidant, and membrane stabilizing properties. They have also been used in treatment of severe traumatic brain injury. The purpose of this study is to determine if early high dose omega-3 fatty acid supplementation in Division I National Collegiate Athletic Association (NCAA) athletes that have sustained a concussion will decrease the number of days out of competitive sports with a quicker symptom resolution, return to baseline neurocognitive functioning and postural stability using a randomized double blind placebo controlled study design. Once an athlete is identified as having sustained a concussion by the East Carolina University Sports Medicine staff and qualifies for the study, he/she will randomly be assigned to either high dose omega-3 fatty acid or placebo. Both groups will undergo standard and usual care for concussed athletes at East Carolina University. The number of days it takes the athlete to return to competitive athletics will be recorded, along with time to symptom resolution, normalization of their computerized neurocognitive testing (ImPact) and computerized postural stability testing (Biodex BioSway).

The goal of this study is to learn more about how Inner Resources for Veterans (IRV), a mindfulness and mantra therapy, helps Veterans with Post Traumatic Stress Disorder (PTSD) and mild traumatic brain injury (mTBI). PTSD is a disorder that occurs after exposure to one or more emotionally traumatic experiences. People with PTSD may experience anxiety, pay extra attention to their surroundings, involuntarily remember their traumatic experiences, and/or want to avoid situations where these symptoms are increased. MTBI may result from being in a blast explosion, with pressure from the blast potentially disrupting the brain's structure and function. At this time, it is not well known how PTSD and mTBI may affect each other. In this study, the investigators will be looking at the behavioral and neurological changes (changes in the brain) and the reductions in PTSD symptoms that may come from participating in this treatment. The investigators are interested in determining if treatment does reverse changes in the brain caused by PTSD and mTBI. To help the investigators understand changes in how the brain functions, the participants will complete a functional magnetic resonance imaging (fMRI) scan before and after either IRV or an active control group. Both conditions are 9-session, 12-week interventions. Participation will help the investigators understand how therapy for PTSD and mTBI impacts the brain's response to emotions and therapeutic processes.

In recent years, media attention has focused on the long-term sequelae of repeated concussive episodes in professional athletes. The growing understanding of the damage done by what was once considered a "ding" during a game or match, and the neurologic consequences of "playing through" or returning to play too soon has led to additional interest in and concern for pediatric athletes (18 or under) who experience sports-related concussions during game or practice play. Because it has only been in recent years that the full scope of damage done by repeated concussive episodes has come to light, very little research has been done on treatment of concussion in either adults or children. Brain injuries in children can be especially problematic, as the brain may continue to develop until the child reaches the age of 24 or older, so concussion during this time of development may be particularly damaging. Docosahexaenoic acid (DHA) is an omega-3 fatty acid commonly found in both fish oils and algae. DHA is known to improve development of the eyes and brain in young children. It is thought to be an effective anti-inflammatory and anti-oxidant, and since it occurs naturally and causes very few harmful side effects, it may be a useful compound in the treatment of pediatric concussion. This is a feasibility trial of DHA for the treatment of sports concussion in a pediatric population. The investigators' primary aim is to determine acceptability of randomization for this compound as well as rate of enrollment given our clinical population. The investigators' secondary aim is to examine preliminary outcomes. The investigators hypothesize that subjects who take 2 g of DHA daily for 3 months will see a shorter time to full recovery and return to play and a shorter time to resolve balance disturbance. These are good, albeit unvalidated, clinical indicators of concussive recovery.

This study is a randomized, placebo-controlled, double-blinded, therapeutic exploratory clinical trial of branched chain amino acids (BCAA's) in the treatment of concussion. The aim of the study is to determine whether, compared to placebo treatment, administration of BCAA's, at one or more doses, after a concussion improves neurocognitive recovery at one or more time-periods post concussion.
