Risk Stratification in Children With Concussion
ConcussionBrain1 moreThis 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.
Non-invasive Brain Stimulation and Injury Risk Biomechanics
ConcussionMildThe goal of this clinical trial is to test the effects of repetitive transcranial magnetic stimulation (theta burst stimulation) on movement biomechanics (jump landing) among individuals with and without a concussion history. The main question it aims to answer is if theta burst stimulation to the left dorsolateral prefrontal cortex improves single- and dual-task jump landing reaction time and jump landing biomechanics compared to a control site (vertex) for individuals with and without a concussion history. Participants will be asked to perform a jump landing before and after the experimental (left dorsolateral prefrontal cortex) and control (vertex) theta burst stimulation protocol. The researchers will compare individuals with and without a concussion history to see if the effects differ between groups.
Establishing Early Exercise Interventions in Concussion Recovery
Brain ConcussionThis is a Phase 1 study to determine (1) the safety of an exercise protocol in adolescents and young adults with concussion in the first week post-injury and (2) to evaluate the effects of mild symptoms on brain function using EEG. This pilot study will inform subsequent grant applications, and a Phase II randomized control trial that will explore the influence of age on an early re-introduction to exercise, as well as the influence of varying intensity levels of exercise.
The Effects of Environmental Distractions on SCAT5 Outcomes
ConcussionBrain1 moreThe purpose of this study is to assess the effects of visual and auditory distractions on SCAT5 scores. The study is designed to identify the effects of about 80 participants completing the SCAT5 in college-aged athletes. All participants will perform the same tasks in two settings (distracted and non-distracted). The central hypothesis is that there will be a significant association between distractions and a lower score on the SCAT5. The cognitive screening, neurological screen, and mBESS should showcase a decrease scores during the distracted environment.
Screening Instruments for Measuring Visual Symptoms in Victims of Concussion
Brain ConcussionmTBI - Mild Traumatic Brain InjuryVisual dysfunction after mild traumatic brain injury (mTBI) is common but often remain undiscovered during longer periods of time. No valid, reliable and easy-to-use screening instrument for uncovering visual dysfunction exists. Furthermore, it is unknown whether optometric measurements currently used in assessing vision problems are consistent with patients' subjective complaints experienced in everyday life. A better understanding of patients' visual challenges combined with objective measurements, will contribute to a better and more efficient diagnostic investigation and treatment. The aim of this study is to get a better understanding of patients who are suffering from visual dysfunction after mTBI. This understanding will be gained by: developing and validating a questionnaire for uncovering subjective visual complaints in subjects with mTBI. developing eye tracking based screening tools applicable both in- and outside of optometry clinics examining relationships between self-reported data, eye tracking measurements and optometric measurements. The study will consist of N = 200 subjects. N = 100 of the subjects are suffering from mTBI (commotio group). The second group N = 100 is the non-injured group that preferably will consist of relatives to the subjects in the commotio group. The subjects in both groups have to answer the questionnaires regarding subjective visual complains, undergo optometric tests and undergo eye tracking measurements.
The Role of Mechanical Diagnosis and Therapy in the Management of Concussion
Brain ConcussionMild Traumatic Brain InjuryThe purpose of this study is to examine the role of a Mechanical Diagnosis and Therapy (MDT) examination in identifying participants diagnosed with concussion who display a directional preference compared to who don't display a directional preference.
Dynamic Vision Testing and Concussion Management Dream Team 65
Head InjurySport Injury2 moreThe purpose of this study is to determine the value of including dynamic vision testing into California State University, Northridge (CSUN) Athletics' established concussion protocol. The study's hypotheses are 1) dynamic vision testing will reveal vision impairments right after a person sustains a concussion, 2) these impairments may still be present upon clearance to return to play.
Score Predicting Lesion Development on CT Following Mild TBI
Traumatic Brain InjuryMild Traumatic Brain InjuryMild traumatic brain injury (mTBI) is one of the most common reasons behind emergency department (ED) visits. A small portion of mTBI patients will develop an intracranial lesion that might require neurosurgical intervention. Several guidelines have been developed to help direct these patients for head Computerized Tomography (CT) scanning, but they lack specificity, mainly focus on ruling out lesions, and do not estimate the risk of lesion development. The aim of this retrospective observational study is to create a risk stratification score that predicts the likelihood of intracranial lesion development, lesion progression, and need for neurosurgical management in patients with mTBI presenting to the ED. Eligible patients are adults (≥ 15 years) with mTBI (defined as admission Glasgow Coma Scale (GCS) 13-15) who presented to the ED within 24 hours of injury to any ED in Stockholm, Sweden between 2010-2020. Reasons for ED visit and Internal Classification of Disease (ICD) codes will be used to screen for patients. Machine-learning models will be applied. The primary outcome will be a traumatic lesion on head CT, defined as a cerebral contusion, subdural haematoma, epidural haematoma, subarachnoid haemorrhage, intraventricular haemorrhage, diffuse axonal injury, skull fracture, traumatic infarction or sinus thrombosis. The secondary outcomes will be any clinically significant lesion, defined as an intracranial finding that led to neurosurgical intervention, discontinuation or reversal of anticoagulant or antiplatelet medication, hospital admission > 48 hours due to the TBI, or death.

MTBI - Mild Traumatic Brain InjuryModerate Traumatic Brain InjuryThe investigators will carry out multi-center and large sample research based on the Chinese population, screen the optimal diagnostic and prognosis recognition biomarkers and analyze the diagnostic critical cutoff values in patients with mild to moderate traumatic brain injury, so as to provide a substantial basis for clinical diagnosis and prognosis recognition.
Imaging of Injury Mechanism and Interaction of Intestinal Bacteria in Children With Mild Traumatic...
MTBI - Mild Traumatic Brain InjuryTraumatic brain injury (TBI) is the leading cause of disability in children and young adults. Children with moderate to severe TBI are typically at risk of poor functional outcome in terms of neurocognitive impairment and behavior problems. Neurocognitive impairments include deficits in attention and working memory, learning and memory, and executive functioning, whereas behavior problems include anxiety, depression and aggression. Neuroimaging techniques based on multi-modal magnetic resonance image (MRI) can detect the structural and functional brain abnormalities objectively and sensitively. Recent evidence indicates that even after mild TBI, children with risk factors for intracranial pathology are at risk of poor neurocognitive and behavioral outcome.Meanwhile, recently, the concept of "gut-brain axis" has been proposed and hint gut microbiota could shape the brain. Some studies have emphasized that human gut microbiota plays an important role in the pathogenesis and development of TBI. However, how the gut affects the brain in patients with TBI is unclear. Thus, combining analysis of neuroimaging and "gut-brain axis" will provide more information for finding the risk factors and imaging diagnostic markers of brain impairment in TBI. It will also helpful for explaining the underlying mechanisms of brain impairment in TBI, providing an objective basis for clinical diagnosis and prediction of the prognosis.
