Mild Traumatic Brain Injury

The goal of this pilot clinical trial is to learn whether memantine can be given safely and successfully to adults in hospital with a mild or moderate traumatic brain injury (TBI). Memantine is approved to treat Alzheimer's disease, but it is not approved to treat TBI. The study will also test whether brain scans and other assessments are suitable for a larger trial. TBI can damage the blood-brain barrier. This protective lining controls what can pass from the bloodstream into the brain. Researchers can measure this damage with a specialized magnetic resonance imaging (MRI) scan using contrast dye. The main questions are: * Can participants start memantine soon after their injury and take it for three months? * How safe and tolerable are daily memantine doses of 20 mg and 30 mg? * Can MRI scans measure changes in the blood-brain barrier from the start of the study to three months? * Can researchers complete the study visits and collect enough information to plan a larger trial? The study will include 45 adults admitted to the Halifax Infirmary in Nova Scotia, Canada, with a non-penetrating mild or moderate TBI. A computer will assign each participant by chance to one of three groups. One group will receive 20 mg of memantine per day. Another group will receive 30 mg per day. The third group will receive usual care without memantine. The memantine dose will increase gradually based on how well each participant tolerates it. Participants will: * Receive usual care, with or without memantine for three months; * Have specialized MRI scans near the start of the study and at three months; * Have recordings of brain activity near the start, at three months, and at six months; and * Complete tests and questionnaires about symptoms, memory, attention, mood, daily function, disability, and quality of life. Researchers will compare the groups to look for differences in blood-brain barrier changes, side effects, and recovery measures. Because this is a small pilot study, it is not designed to prove that memantine improves recovery. Its results will instead help researchers choose a dose, assess safety of drug delivery, and design a larger trial.

The goal of this clinical trial is to compare outcomes for standard vestibular rehabilitation home program to a digital vestibular rehabilitation home program in adults with dizziness related to mild traumatic brain injury (mTBI). The main question is whether participants who use the digital format of vestibular rehabilitation improve to a greater extent at discharge than those who use the standard format. Participants will undergo a customized vestibular rehabilitation home exercise program per standard of care, consisting of gaze stabilization, habituation, balance and gait exercises, and endurance training under the supervision of a physical therapist. Participants will complete the gaze stabilization and habituation exercises 2-3 times per day and the balance and gait exercises 1 time per day for 4 weeks. Participants will be tested before and after the 4-week intervention. At the initial session, the researcher will perform standard clinical tests of the inner ear balance system. Also at the initial session, the researcher will perform standard clinical tests of balance and walking and questionnaires about the impact of dizziness on daily activities. At the final session, the researcher will repeat the tests of balance and walking and questionnaires. Three months after completing the intervention participants will complete an online questionnaire about the impact of dizziness on daily activities.

The goal of this clinical study is to evaluate how accurately and safely the TES HT100 device can identify intracranial abnormalities in adult emergency department patients with mild head trauma or neurological symptoms that are not related to trauma and are not immediately life-threatening. The main questions it aims to answer are: * How well does TES HT100 identify patients with intracranial abnormalities compared with head CT, the reference standard? * Is TES HT100 safe to use in this patient population? * Could TES HT100 help improve patient triage and use of hospital resources in the emergency setting? Researchers will compare the result of TES HT100 with the head CT report. Participants will: * Be enrolled if they are adults presenting to the emergency department with mild head trauma or selected neurological symptoms * Undergo standard clinical assessment and head CT according to usual care * Have an additional TES HT100 examination lasting about 5 minutes, performed by trained personnel * Be assessed for device performance and any adverse events related to use of the device

KIDS-STAT is a prospective study evaluating whether a rapid blood test measuring the brain injury biomarkers GFAP and UCH-L1 using the i-STAT Alinity system can help identify children with mild traumatic brain injury who do not have acute traumatic findings on head CT. The study will include children younger than 18 years who present within 24 hours of a suspected mild traumatic brain injury. Blood will be collected during the emergency department visit and tested using the i-STAT TBI cartridge. The test results will be used for research purposes only and will not be used to make clinical care decisions. The primary objective is to determine how reliably a negative i-STAT TBI result identifies children without traumatic findings on head CT. Secondary analyses will evaluate test performance across age groups and in relation to clinical characteristics and outcomes.

Many combat veterans (c-Vs), service members (SMs) and civilians with mild traumatic brain injury (mTBI, also termed concussion) suffer from persistent post-concussion symptoms (PPCS) that degrade physical and cognitive well-being and have been linked with early neurodegeneration. PPCS include somatosensory (e.g., headache, disturbed vision), vestibular (e.g., dizzy, clumsy), cognitive (e.g., executive function, memory) and affective symptoms (e.g., sleep disturbance, irritability, depression). A key pathological process that provokes and perpetuates PPCS is autonomic nervous system (ANS) dysfunction such as unremitting sympathetic nervous system activation that also exacerbates other pathology such as inflammation. ANS activity can be readily quantified by measuring heart rate variability (HRV), or the variation in heart rate over time, which serves as a valid index of both physiological and psychological health

Approximately 5.3 million people live with a long-term disability resulting from a traumatic brain injury (TBI) and between 5-8% of those older than 60 suffer from Alzheimer's disease or other forms of dementia (ADRD). Consequences of these conditions can result in dramatic and persistent changes in functioning, impacting not only the patients, but also loved ones who become informal support persons. Many existing services help the family in the moment, but do not address long-term wellness. Thus, the purpose of this research study is to compare the effect of two different types of group wellness treatments for individuals with chronic mild TBI, moderate to severe TBI, and ADRD and their support persons.

This project investigates an innovative combination of non-invasive neuromodulation (transcranial direct current stimulation - tDCS) and cognitive training as a novel treatment approach aimed at improving function in individuals suffering from persistent post-concussive syndrome (PPCS) following mild traumatic brain injury (mTBI).

This is a research study that aims to examine whether Veterans with mild Traumatic Brain Injuries are at risk for dementia by studying their memory, brain wave activity, brain structure and proteins that can be elevated after brain injury and in dementia.

This study will probe if the biological changes in amnestic mild cognitive impairment (aMCI) are related to a history of mild traumatic brain injury (mTBI) using high definition transcranial direct current stimulation (HD-tDCS) and blood-derived biomarker tools. Participants who Do as well as those who Do Not have a history of mTBI will be enrolled in the study.

This project will measure concussion symptoms, biological markers, and academic and social factors across the first year postconcussion to develop a model that enables early identification of and symptom management for children at higher risk for persistent postconcussive symptoms. Findings will provide novel insights into the longer-term effects of concussion on children's physical, psychological, and social well-being and support the development of personalized healthcare and school-based plans to reduce disparities in children's ability to return-to-learn and -play and improve postconcussion quality of life.

The purpose of this study is to determine whether growth hormone replacement therapy (GHRT) is effective versus placebo in the improvement of Quality of Life in patients with adult growth hormone deficiency (AGHD) and mild traumatic brain injury (mTBI).

Concussion or mild traumatic brain injury (mTBI) is a major public health concern. Most adolescents will recover from mTBI without complication; however, a sizeable minority experience symptoms that last more than one most post-injury (i.e., persisting symptoms after concussion). Few evidence-based treatments exist for adolescents with persisting symptoms after concussion. Mindfulness-based interventions (MBIs) are effective for treating a wide range of mental and physical health conditions that overlap with post-concussion symptoms. Participants will participate in an 8-week smartphone app-based MBI or a health education program as a control. The study will determine the practicality of doing a larger study to evaluate the effectiveness of the MBI by assessing participants' level of interest, view of intervention helpfulness, and their completion of all the components of the study.

Rationale: In the Netherlands, traumatic brain injury (TBI) is one of the most frequent neurological diseases and one of the leading causes of disability. Presumably, about half of the total Dutch population will get a TBI during their lifetime. The majority, about 85%, of patients suffers from a mild TBI (mTBI). The incidence of mTBI is estimated at 68,000 patients each year, but this is an underestimation as patients seen at the general practitioner's offices are not taken into account. In general, the prognosis of mTBI is relatively good, however more than 70% of patient still have one or more post-traumatic complaints at six months post-injury influencing resumption of daily (social) activities and return to work/study. Considering the high annual incidence of mTBI the number of patients with incomplete recovery has high social impact accompanied with excessive health care related costs. Post-traumatic complaints in the chronic phase postinjury are considered therapy resistant and so far no evidence based treatment is available. Hence, the most appropriate strategy is to prevent complaints present in the (sub)acute phase after injury to become persistent to improve functional outcome and quality of life. Objective: The main aim of this study is to improve early care for patients suffering from post-traumatic complaints after mTBI through the development of effective symptom-guided tailored interventions. Nowadays, no effective therapy is available and care-as-usual consists of a wait-and-see policy. Early therapy will reduce posttraumatic complaints and facilitate earlier return to daily activities and work or study, consequently quality of life will be improved as well. This in turn will result in less healthcare consumption and lower societal costs. Study design: The investigators propose a prospective three-arm multicenter open randomized controlled trial (RCT), randomizing participants between two interventions and care as usual. The end-point assessment is blinded. Study population: Adults, aged 18-70 years, diagnosed with a mTBI at the Emergency Department (ED) of the participating hospitals within 24 hours after injury are eligible for inclusion. Intervention: At two weeks post-injury the presence, severity, and type of post-traumatic complaints are assessed using the Rivermead Postconcussive complaints Questionnaire (RPQ). If a predefined minimum of complaints is present, a participant is randomised for one of the two interventions or the control group. The first intervention arm consists of symptom-targeted treatment with assignment to physical and/or occupational therapy. The second intervention arm involves psychoeducation about the complaints through telephonic counselling. The interventions are offered during three weeks from week 3-6 week post-injury. Main study parameters/endpoints: The primary outcome measure is the total RPQ sum score at three months postinjury. The secondary outcome measures are functional outcome and quality of life. Nature and extent of the burden and risks associated with participation, benefit and group relatedness: Participants included in treatment arm 1 will undergo three to six therapy sessions with a physiotherapist and/or occupational therapist over a period of three weeks. This regimen may be potentially burdensome by its frequency but the risks associated with these treatments are low. Participants randomised to treatment arm 2 will receive three telephone calls over the course of three weeks, during which psychoeducation will be provided. This intervention is minimally burdensome and risk-free. All participants included in the interventional part of the study will complete questionnaires at three time points after injury and will receive two follow-up telephone calls three and six months post-injury for outcome assessment. This process is minimally burdensome and poses no risk. Finally, participants included in the registry will complete a limited set of questionnaires at three time points, which is also minimally burdensome and riskfree.

The purpose of the study is to test two different training programs to find out which is better at helping people with a concussion or mild TBI (mTBI) improve their emotional health and well-being. Study participation is completely remote and will last approximately 8 months total, involving 4 assessment visits and 8 sessions of brain training via a secure video-conferencing platform. The 4 assessment visits (about 30-90 minutes each) include surveys and questionnaires about participant's emotional health. These assessment visits will take place before the training, immediately after the training, 3 months after training and 6 months after training. The 8 sessions of 1-on-1 training (about 60-90 minutes each) will be completed over the course of approximately 1 month.

Persistent memory symptoms after concussion are common, and likely perpetuated by unhelpful illness beliefs and coping behaviors. Results from a pilot study suggested that traditional cognitive rehabilitation and a novel cognitive-behavioral therapy (CBT) protocol were both associated with improvements in subjective memory functioning. The present study will more definitively compare the effectiveness of these interventions for improving subjective memory functioning after concussion.

The goal of this hybrid implementation-effectiveness study is to evaluate the effectiveness (hastened recovery times) and feasibility (fidelity in connecting to concussion specialty care) of a novel mobile health intervention, designed to reduce disparities in access to specialty care through the use of remote patient monitoring (RPM) to facilitate care hand-off from the emergency department (ED) to concussion specialty care. Participants will report their symptoms and activity once daily through RPM chat technology that is linked to their electronic health record and prompts referral to specialty care.

The purpose of this research is to demonstrate that mild stimulation of a nerve (trigeminal nerve) in the head can modulate blood flow in the brain. The modulated blood flow will restore the flow of cerebrospinal fluid (CSF) and this in turn can help improve waste clearance in the brain and prevent build up that may lead to disease.

This study will determine (i) the magnitude of immediate and sustained effects of a current clinical standard interactive computer attention processing training (APT) when combined with intermittent theta burst stimulation (iTBS), a type of repetitive transcranial magnetic stimulation and (ii) determine how APT + iTBS changes the neurocognitive system of attention in individuals with persistent attention deficits related to mTBI +/- PTSD.

Among fall related injuries in older adults, head injuries are the most common, yet almost nothing is known about recovery from head injury, also known as traumatic brain injury or TBI, in this population. The RETRO-TBI study is a prospective cohort study of 250 adults aged 65 and older with mild TBI to evaluate recovery in cognitive, physical and psychological function and sleep quality at four timepoints (2 weeks and 3, 6, and 12 months) over the year following injury and identify factors associated with recovery trajectories. The potential impact of this work is that it will generate new knowledge that will guide targeted treatment efforts and inform future development of strategies to optimize recovery following this common fall-related injury among older adults.

This study will employ cognitive behavioral therapy for insomnia (CBT-I) among individuals with mild traumatic brain injury (mTBI) who experience sleep disturbances. The research aims to evaluate the effects of CBT-I on sleep, mTBI symptoms, and, in particular, the ability of individuals with mTBI to engage in their desired daily life activities. The main questions this study aims to answer are: 1. Does CBT-I positively impact symptoms of mTBI? 2. Does CBT-I improve functional performance in individuals with mTBI?

The primary goal of this clinical trial is to evaluate whether Personalized Augmented Cognitive Training (PACT) plus intermittent theta burst stimulation (iTBS) is effective for treating depression in Service Members, Veterans, and civilians who have sustained a mild TBI. Participants will receive PACT plus 20 sessions of iTBS or sham iTBS over 4 weeks. Assessments will occur at baseline, 2 weeks, 4 weeks, and 8 weeks. Researchers will compare the PACT+iTBS group to the PACT+sham iTBS group to see if PACT+iTBS is associated with more depression improvement.

The purpose of this study is to investigate the efficacy, safety, and tolerability of two dorsolateral prefrontal cortex (DLPFC) repetitive transcranial magnetic stimulation (rTMS) protocols to alleviate symptoms of depression in United States (U.S.) military service members and veterans with a history of concussion/mild traumatic brain injury (TBI).

Posttraumatic stress disorder (PTSD) and mild TBI (mTBI) frequently co-occur in post-9/11 Veterans, and together are associated with worse cognitive performance, mental health, everyday functioning, community integration, quality of life, and treatment response than either condition alone. Additional comorbidities, such as depression and sleep disturbance, are common and further exacerbate these problems. The investigators will investigate Compensatory Cognitive Training (CCT) and Morning Bright Light Therapy (MBLT) vs Negative Ion Generator (ION), to directly target cognition, depression, and sleep disturbance and to improve CCT-associated rehabilitation outcomes. The investigator's randomized controlled trial in 144 Veterans with mTBI+PTSD across two VA sites will compare cognition, functioning, and other secondary outcomes following CCT+MBLT vs. CCT+ION. This study addresses the significant gap in services and evidence-based treatments for Veterans with mTBI+PTSD.

The investigators hope to develop a treatment for suicidal ideation (SI), impulsivity and functional impairments (such as difficulties in social and work settings) that occur after a mild traumatic brain injury (mTBI). These conditions have been shown to be linked. The investigators are using a high-powered magnetic pulse, called intermittent theta burst stimulation (iTBS) applied to the head to see if it can improve these symptoms. The high-powered magnetic pulse causes certain cells in the brain to activate, which seems to strengthen connections between parts of the brain. The purpose of this research is to gather early information on the safety and effectiveness of iTBS provided to the front of the head for impulsivity, SI and functional deficits after mTBI. The investigators plan to use the data collected in this study to develop larger studies in the future. iTBS is FDA approved, but not for these specific symptoms, or in the specific location the investigators are placing it. The investigators are testing to see if its effective for the above conditions when applied to the front of the head.

Investigators will conduct a randomized controlled trial assessing the effectiveness and implementations of Pre-Game Safety Huddles (Huddles) in youth soccer.
