Active clinical trials for "Brain Injuries, Traumatic"

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 the Emergency Department (ED) or concussion clinic.

Traumatic brain injury (TBI) is defined as a structural alteration of brain function caused by external causes, where mild traumatic brain injury (mTBI) represents approximately 80% of all TBI, and although its prognosis is relatively good, it represents a significant cost to the system due to the need to perform a cranial computed tomography (CT) scan, a test of high economic value and not without risks such as irradiation, especially important and dangerous in the pediatric age. The investigators aim to set-up a point of-care (POC) device to validate a biomarker (H-FABP) able to diagnose the presence of brain damage in children and adults with mTBI at trauma and paediatric Emergency Departments using a blood sample, in order to save resources and avoid subjecting patients to a potentially damaging imaging test. But also, to assess whether the incorporation of new biomarkers improves the prediction of brain damage that can be done with H-FABP. For that, the investigators will recruit a 400 patients' cohort with blood samples using the available POC device for H-FABP biomarker.

The purpose of this study is to investigate the role of cognitive reserve in change in connectivity in the brain (measured with functional magnetic resonance imaging, fMRI) and how this is related to symptoms and symptom resolution.

This study examines the possible microstructural changes in the brain during recovery after mTBI using diffusion MRI.

This study (Part 1) 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).

The purpose of this study is to show if it is possible to detect secondary ischemic events in patients with severe brain injury or cerebral haemorrhage with the help of non-invasive near-infrared spectroscopy (NIRS) by using the indocyanine green measuring of cerebral perfusion.

The purpose of the study is to gather information about patients with mild traumatic brain injury in order to develop guidelines for evaluation and treatment.

The goal of this project is to develop a test to assess frontal lobe function using a rapid, inexpensive, objective, and standardized method, without the need for expertise in cognitive test administration. Such methods would be particularly helpful in traumatic brain injury (TBI), where objective measures are needed, and would greatly expand the capacity to make such assessments in clinical practice and research.

The study will provide evidence on the long term outcomes of mTBI in service members returning from Afghanistan and Iraq. In addition, the study will provide evidence on mTBI incidence, and symptom patterns. Self-reported assessments at baseline and follow-ups will be combined with data on health care utilization and military job performance. The work, symptoms, and family interaction outcomes of returning soldiers screening positive for mTBI, combined mTBI and PTSD, and soldier controls will be compared at 3 months, 6 months, and at one year. The assessments over time will permit descriptions of symptom changes for these populations. It is likely the study will find similar findings to those of previous civilian studies - that concussive symptoms often resolve within months of injury. However, some soldier subsets may have chronic problems. Determining the incidence and outcomes of individuals with mTBI will assist medical providers in determining the types of follow-ups needed by returning service members and suggest the development of additional treatment interventions. These results may also inform treatment of civilian populations with mTBI. The three primary hypotheses are: Concussive symptoms at the time of return from serving in Afghanistan and Iraq and symptoms persisting 3 months, 6 months, and 12 months after return will be associated with extent of exposure to combat, injury mechanism, associated injuries (co-occuring injuries), PTSD and other psychiatric co-morbidities, and number of deployment-related mTBIs. Returning troops reporting concussive symptoms at the time of return from deployment will have more work related problems at each follow-up (including lower rates of return to duty, return to work, and poor quality of work). The mTBI screening tool will be sensitive and specific to mTBI when compared to the criterion measure, which is a structured interview conducted by clinicians blinded to the screening results.

The purpose of this study is to determine whether the brains of persons with and without traumatic brain injury differ in a meaningful way when advanced technology images of the brain are taken using three newer technologies that visualize the brain using a combination of external/internal magnetic fields and radioactive tracers (molecules that emit detectable particles). The hope is that the results of this study will validate tools (help prove that diagnostic tools actually detect disease) for the diagnosis and treatment of traumatic brain injuries (TBI).
