Active clinical trials for "Brain Concussion"

The main purpose of this study is to prospectively examine changes in Brain Network Activation(BNA)following concussion in high school athletes. In addition, the study will examine the relationship between changes in BNA to symptoms, cognitive performance and vestibular function from baseline to 1-7, 8-14 and 15-21 day post injury intervals in high school athletes with concussion.

There will be 200 participants, who aged 30 years or older with TBI in 1,5,10,15 years ago and GCS=13-15 will be recruited. Another group of 200 participants with the same age and gender and without TBI will be recruited as the controls. All of them will undergo AD8 questionnaire for dementia screening and APOE4 genotyping. Further CASI and CDR will be tested for the confirmation of dementia diagnosis for the individuals with AD8 scaore >/=2. 10 TBI with dementia, 20 TBI without dementia and 10 controls will be selected randomly for AV45 amylid PET study. There will also be 10 participants without traumatic brain injury and interested in this study, aged 55 years or older better.

This study utilizes multimodal brain imaging to obtain quantitative biomarkers of brain injury and to improve understanding of the biological basis of brain pathology in adolescents with concussion. Adolescents with a concussion will undergo neuroimaging and neuropsychology assessments acutely and four months after injury.

The HS-1000 is an innovative non-invasive monitoring device that employs advanced acoustic signal analysis to calculate ICP on a continuous basis. Initial HS-1000 clinical data also shows promise in assessing a variety of cerebral hemodynamic parameters such as cerebral blood-flow, auto regulation monitoring, and cerebrovascular vessels compliance. In the absence of a non-invasive monitor of intracranial pressure (ICP), the relationships, if any, that may exist between concussion, timing of the concussion (e.g. acute, resolving, resolved) and ICP is unknown. The new HS-1000 non-invasive device may provide insight into assessment of possible ICP changes following concussion in children.

Background: Patients with mild traumatic brain injury can to some extend experience long-term physical, cognitive, social and behavioral deficits, which have serious implications for employment trajectories and financial independence. These deficits have shown to be more pronounced in women. High socio-economic position such as income, level of education and employment status before the accident have shown to affect return to work. But also cohabitation status, ethnicity and health are important factors. Previously studies are typically self-report studies, and are often small and may suffer from selection bias due to patient nonresponse. Aim: The aim of this study is to describe no return to work among patients with mild traumatic brain injury in Denmark and to examine how factors such as age, gender, cohabitation status, socio-economic and pre-injury health factors affect no return to work up to 5 years post-injury. Hypothesis: We hypothesize that most patients with mild traumatic brain injury return to work within work 6 months post-injury, and that patients with mild traumatic brain injury injury receive more social transfer payments compared to the general population. Additionally, we hypothesize that low socio economic position, comorbidities and being single are associated with prolonged no return to work. Methods: The present study is an observational national register-based cohort study with long-term follow up of patients with mild traumatic brain injury from 1st of January 2008 - 31st of December 2012 in Denmark. Patients aged 18-60 years diagnosed with concussion from 1st of January 2003-31st of December 2007 in the national patient register will be included in the study. Data will be retrieved from several national databases, including the DREAM database containing data on social benefits and reimbursements. Primary outcome is no-return to work (nRTW) due to any cause and the following four secondary outcomes are graded and should be regarded as a continuum ranging from health related nRTW, limited nRTW, permanently nRTW and mortality. The results will be published as two separate scientific articles.

This study was conducted to develop and validate integrated eye tracking and EEG measures for assessment of mild traumatic brain injury.

The purpose of this study is to determine the sensitivity and specificity of an aid in assessment of concussion based on eye-tracking, in comparison to a clinical reference standard appropriate for sport-related concussion evaluation.

This is a prospective, non-blinded, matched control study of young athletes (ages 10-28 years old) in collegiate sports. The cohorts are defined in accordance to the athlete's exposure of injury. All subjects will complete a minimum of one recording based on their assigned cohort. Concussed athletes will complete an additional 3 weeks of follow-up recordings post injury. The symptomatic evaluation, physical examination, neurological baseline testing, and BrainPulse recordings will be entered in a database to determine clinical outcome and assess device utilization.

This study is Part 1 of data collection from 18-25 years old subject population for validation of previously derived algorithms. This data will be combined with that collected under NCT03671083 (Part 2 with subject age range 13-25 years) for the final analyses of validation of the algorithms.
