Active clinical trials for "Brain Injuries, Traumatic"

Veterans with traumatic brain injury (TBI) frequently experience insomnia, which is linked with delayed TBI recovery, more severe functional impairment, and exacerbation of disabling TBI after-effects such as depression, chronic pain, and fatigue. Current research suggests that TBI can impact numerous systems involved in sleep, suggesting that insomnia can have various causes and that a "one-size-fits-all" approach to treatment is likely inadequate. As such, it is necessary to determine which Veterans may benefit from standard evidence-based treatments, such as Cognitive Behavior Therapy for Insomnia, and which may require enhanced treatments targeting specific underlying mechanisms. An emerging body of evidence has established a link between circadian rhythm disruption and post-TBI insomnia. A mismatch between circadian and desired sleep timing (i.e., "circadian misalignment") is common following TBI, as evidenced by disruptions of key circadian rhythms involved in sleep regulation (e.g., melatonin production), as well as the onset of circadian rhythm sleep-wake disorders. Importantly, circadian-driven sleep disturbances require specialized treatments that target circadian rhythms (i.e., "chronotherapies"), such as timed sleep windows or enhanced light exposure, as standard treatment approaches can fail to address or even exacerbate the underlying circadian misalignment. Thus, circadian misalignment represents a novel and modifiable treatment target and has the potential to improve functional outcomes in Veterans with TBI and insomnia. Detection of circadian misalignment and optimal use of chronotherapies require the ability to measure circadian phase (i.e., timing of the central circadian clock). However, current sleep medicine in TBI is hampered by a lack of pragmatic options for measuring circadian phase. This is because laboratory dim light melatonin onset (DLMO), the gold standard measure of circadian phase, is time and cost prohibitive, requiring specialized sample (e.g., saliva) collection facilities and placing substantial burden on the patient. Recently, novel methods of DLMO measurement have been developed that may enhance the accessibility and practicality of circadian phase assessment, although, as of yet, they have not been used in Veterans with TBI. The proposed single-arm, longitudinal study seeks to evaluate the feasibility of two methods of measuring DLMO in the home environment of Veterans with TBI and insomnia: 1) direct measurement of self-collected salivary melatonin; and 2) indirect estimation of DLMO using activity and light-exposure data collected through actigraphy. Additionally, this study seeks to explore the relationships between circadian misalignment, sleep disturbance, and functional impairment in Veterans with TBI. The specific aims of this study are to: Aim 1) evaluate the feasibility of two methods of home DLMO measurement (i.e., self-collected salivary melatonin and actigraphy data) in Veterans with TBI and insomnia; and Aim 2) examine associations between circadian misalignment (i.e., the difference in timing between DLMO and attempted sleep onset), sleep disturbance, and functional impairment. Veterans with TBI and insomnia will be asked to wear a wrist-based actigraphy device for one week, which will collect data on light exposure and sleep-wake states. They will then be asked to self-collect seven hourly saliva samples under dim light conditions in their own home and mail them to a testing facility using a provided pre-paid shipping label. Saliva samples will be used to directly measure DLMO and actigraphy data will be used to indirectly estimate DLMO using established mathematical models of the human circadian pacemaker. Evaluating the feasibility of home DLMO measurement is a crucial first step for enhancing precision sleep medicine for Veterans with TBI and insomnia. Findings will inform the development and testing of tailored sleep interventions for use with this patient population.

The aim of this study is elucidate genetic susceptibility of patients with traumatic brain injury (TBI) and symptoms of Brain Injury Associated Fatigue and Altered Cognition (BIAFAC) using genome-wide association study (GWAS).

A prospective cohort study (questionnaires), with an embedded case control study (neuropsychological assessments) in which the data is gathered within a timeframe of 3 years. A group of 700 patients and a group of 100 healthy volunteers will be participating.

The overarching goal of this study is to improve understanding of the long-range natural history of TBI by extending follow-up of a previously enrolled cohort (TRACK-TBI) beyond the first 12 months after injury.

Diagnosing and determining the severity of a sports-related concussion immediately on- or off-field is challenging, especially because clinical signs can evolve minutes to hours after the mechanism of injury. Hence, repeated follow-up and serial assessments of a player are recommended following such an injury. Current advice, when a player sustains a confirmed or suspected concussive injury, is to remove them from play immediately and not return to competition or unrestricted training until signs and symptoms have been managed as per relevant guidelines. To support this decision the International football Association Board has introduced a trial allowing an additional permanent concussion substitution in participating competitions. Follow-up assessment of concussion incidents is recommended to include the Sport Concussion Assessment Tool 5th Edition. For further assessment of neurocognitive deficits and to inform return to play decisions, it is recommended that a computerised assessment is also adopted, such as the Immediate Post-Concussion Assessment and Cognitive Testing tool. The aims of this study are: To determine the incidence of head trauma and use of concussion substitutions in football competitions that are participating in the IFAB's permanent concussion substitution trial. To evaluate the immediate severity of reported concussion signs and symptoms for football players with a confirmed or suspected concussion. To evaluate the ability of neurocognitive assessments completed post-incident to inform the clinical diagnosis of concussion.

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 test the drug apomorphine in subjects who are in a Vegetative State or a Minimally Conscious State.

Telerehabilitation is a service delivery method that has grown substantially in recent years. It has both advantages and disadvantages in comparison to clinic-based services. For example, telerehabilitation is advantageous for people residing in locations in which specialized rehabilitation services are scarce; however, it has the disadvantage of being dependent on reliable internet connections that are not available in all locations. Also, some people prefer the privacy afforded by receiving treatment in their home, but other people prefer the interaction with other clients with similar challenges afforded by attending sessions in clinic-based settings. Other questions about advantages and disadvantages of telerehabilitation remain unexplored. One such question is the focus of this research and concerns the effect of receiving post-acute telerehabilitation services versus clinic-based services on the general well-being and quality of life experienced by people with traumatic brain injury. The study purpose is to compare changes in wellness and quality of life occurring over a four-month period during which people with traumatic brain injury receive post-acute services either via telerehabilitation or at an outpatient facility.

The overall aim of the MAST trial is to define best practice in the use of anti-epileptic drugs (AEDs) for patients following a traumatic brain injury (TBI). The trial will consist of two parts. The first part aims to answer whether a shorter or a longer course of AEDs is better to prevent further seizures in patients who have started having seizures following TBI (MAST - duration). The second part aims to answer whether a 7-day course of either Phenytoin or Levetiracetam should be used for patients with a serious TBI to prevent seizures from starting (MAST- prophylaxis).

Head trauma is a frequent reason for consultation in the emergency room. The CT scan is the reference examination allowing rapid management of the patient. However, CT examinations are among the diagnostic examinations with the highest exposure to ionizing radiation. The study investigators have previously implemented "ultra-low dose" (ULD) acquisitions for several pathologies with an effective dose level similar to that of a standard radiographic examination. These ULD acquisitions are now routinely used in our clinical practice for explorations of the thorax, spine, pelvis and proximal femurs, extremities. This study expands these ULD acquisitions to skull CT for detecting traumatic intracranial lesions. The study investigators hypothesize that it would be possible to search for intracranial lesions in patients with head trauma using ULD protocols, thereby reducing the doses delivered to the patient while maintaining sufficient image quality for the diagnosis.
