Active clinical trials for "Brain Concussion"

Concussions occur most frequently in adolescents and often result in significant disruption to daily living for prolonged periods of time. Concussions are an epidemic, with the incidence rates for sports related concussions (SRC) in adolescents up to 0.47 per 1000 athlete exposures. Research would suggest that multi-planar neck strength is a protective factor of SRC risk in adolescents as greater neck strength is associated with a lower SRC risk.(Collins et al) Neck pain is a common symptom associated with SRC that is also associated with prolonged recovery from SRC. (King et al, Van der Naalt et al) Neck pain is also associated with decreased neck muscle strength (DeKoning et al). Our study will address a critical gap in concussion management - multi-planar cervical spine strengthening to specifically rehabilitate the cervicogenic component of prolonged post-concussion symptoms with a cervicogenic component and determine if this approach restores normal neck strength, decreases neck pain and headaches, improves daily global function and allow patients to return to sport and school. work more quickly than those without specific multi-planar neck strengthening.

EEG signals have been collected and studied since the early 1990's as a way of assessing brain function at a gross level. As early as the 1930's a derivative of the raw EEG signal - event-related potentials (ERPs) - have been computed. The current research is primarily focused on three ERP components: the N100, P300 and N400. Each of the three ERPs have been studied in the academic laboratory for multiple decades. Through this research, a strong understanding has been developed regarding what can affect these components (e.g. task set, emotional state, etc.). However, these signals within various pediatric populations (e.g., those with persistent mTBI symptoms or multiple concussions) are not well characterized. Being able to safely and effectively employ the NeuroCatch™ Platform in a post-concussive pediatric cohort could provide researchers with the potential to elucidate the persistence of objective measures of impairment, patterns of recovery, and chronicity of problems due to mTBI in children. Secondly, understanding the degree to which these neurophysiological components fluctuate over time is crucial to the understanding of brain functioning. However, for this type of technology to be useful in quantifying brain health in this population,the degree to which a post-concussive pediatric brain naturally fluctuates in its processing capability must be quantified. NeuroCatch™ Platform has the ability to measure changes in several domains of brain function. These cognitive processes are foundational blocks for some of the highest cognitive processes: information integration and executive functioning.

Background: - Some people who have a traumatic brain injury (TBI) recover completely. Others, however, develop post-traumatic stress disorder (PTSD), with anxiety and depression. Research suggests that levels of a brain chemical called GABA may differ in people with PTSD compared to those without PTSD. Researchers want to see if TBI can affect GABA in the brain and help develop PTSD. To look at the brain, researchers will use imaging studies with the chemical 11C-Flumazenil, which will help the scan show GABA levels in the brain. Objectives: - To study the relationship between PTSD and TBI. Eligibility: The subjects will be recruited from the Walter Reed National Military Medical Center (WRNMMC). Individuals between 18 and 50 years of age who have PTSD and/or had a mild TBI. Healthy individuals between 18 and 50 years of age who have no history TBI and no history of PTSD. Design: Participants will be screened with a physical exam and medical history. Urine and breath samples will also be collected. Participants will have two imaging studies, on the same day if possible. The first will be a magnetic resonance imaging scan to look at the brain. The second will be a positron emission tomography scan with the study chemical to look at GABA pathways in the brain....

Sport-related concussions occur during different types of sport and are still an underestimated brain injury. Especially children are affected due to their lacking movement control and thereby at higher risk of situations leading to concussion. However, research about the rehabilitation of balance and coordination in children after sustaining a concussion is lacking. Therefore, the return-to-sport question cannot be answered reliable due to the missing understanding of the underlying mechanisms disturbing coordination, yet. Analyzing postural control, meaning the ability of the body controlled by the brain to maintain balanced, is suggested to be a valid method to investigate movement coordination. A newer method to analyze postural control using reflective marker data will be used to study the rehabilitation process. The findings may help to improve concussion treatment and give implication to the return-to-sport decision. The investigators expect to see an altered postural control after sustaining a concussion visible in the movement amplitude especially short after the injury. Moreover, the researchers assume coordination patterns which are not visible to be altered for an extended time period of up to 30 days as well. Participants will be children aged 10 to 16 years and the aim is to recruit 30 children and adolescents who suffer from a concussion. The data of the concussed participants will be compared with data of healthy volunteers.

Management of traumatic brain injuries causes significant efforts on emergency departments (ED) and overall health care. Patients on antithrombotic treatment with even minor trauma to the head, although without significant clinical findings, represent special challenges because the risk of traumatic intracranial hemorrhage (tICH) with these agents. The aim of this study was to compare the prevalence of tICH in patients on various pre-injury antithrombotic treatment exposed to minor Traumatic Brain injuries (mTBI) in Sundsvall with untreated patients. Secondary aim was to explore different risk factors for tICH. Data from medical records and radiology registry with mTBI in Sundsvall hospital between 2018-2020 in Sundsvall identified 2044 patients. Demographic data, pre-injury medications with antithrombotic treatment, state of consciousness at admission and the results of CT-scans of brain was investigated.

The investigational device used in this clinical investigation, the Nurochek Headset, is a portable electroencephalogram (EEG) headset which delivers a visual stimulus and measures a VEP. The visual stimulus is delivered to the subjects' eyes via light-emitting diodes, and the EEG measures the user's visual-evoked potential. This headset communicates with an application on a smartphone which processes the signals and transmits them to a secure cloud server for analysis and storage of the data. The primary objective of this clinical investigation was to evaluate the performance of the investigation device (NCII) against clinical diagnosis and SCAT 5, in the accurate detection of mild traumatic brain injury (mTBI). The primary endpoint outlined for this study was set at the collection of 100 valid investigational device readings from individuals with concussion The aim of this study was to collect data from 100 readings from individuals with concussion. It was estimate that approximately 10-20% of baselined players would suffer a concussion during the season. There it was estimated there would be a need to baseline 500-1000 individuals in order to achieve the number of concussions required. The initial assumption was that sites would provide players pre-season and make players available for testing post-concussion. In practice, some sites provided player data only post-concussion event (such as medical clinics). Participants were required from sporting clubs, medical clinicals and schools.

This study (Part 2) is designed to build a database including EEG, neurocognitive performance, clinical symptoms, history and other relevant data, which will be used to derive a multimodal EEG based algorithm for the identification of concussion and tracking of recovery. In addition, neuroimaging will be conducted at time of injury and following Return to Play (RTP).

To use the Nautilus BrainPulse to compare and contrast the signal patterns from this cohort's signal patterns with those of concussed high school athletes.

Using the Blink Reflexometer, athletes are scanned if they are potentially thought to have a concussion during a game or practice.

This study is Part 2 of data collection from 13-25 years old subject population for validation of previously derived algorithms. This data will be combined with that collected under NCT02957461 (Part 1 with subject age range 18-25 years) for the final analyses of validation of the algorithms.
