Imaging Biomarkers of Mild Traumatic Brain Injury: a Longitudinal Cohort Study
Mild Traumatic Brain InjuryPosttraumatic Stress Disorder2 moreThis longitudinal cohort study aims to detect the topographical nature of the white matter microstructure and resting state functional connectivity patterns across the whole brain in the evolution of pathology as a function of time following mild TBI. All consecutively patients with the non-contrast head CT because of acute head trauma from the local emergency department (ED) formed the initial population of this study. Age, sex, education-level matched healthy controls will also be enrolled. The initial scan will performed within 7 days post-injury. Clinical assessment was performed within 24 hours of MR imaging and included a broad neuropsychological and symptom assessments. Follow-up examination will conduct at 1 month, 3 month, 6-12 months.
Study on Cerebral Protection of Dexmedetomidine for Patients With Traumatic Brain Injury
Traumatic Brain InjuryThe aim of the study is to investigate whether dexmedetomidine could suppress catecholamine release into peripheral blood to prevent PSH attacks and to achieve neuroprotection.

Automated Measurement of Optic Nerve Sheath Diameter
Traumatic Brain InjuryAcute Brain Injuries1 moreOptic Nerve Ultrasound (ONUS) is a promising non-invasive tool for the detection of raised Intracranial Pressure (ICP). Variability in the optimal Optic Nerve Sheath Diameter (ONSD) threshold corresponding to elevated ICP in multiple studies limits the value of ONUS in clinical practice. The investigators goal is to develop and validate an automated image analysis algorithm for standardization of ONSD measurement from ultrasound videos. Patients with acute brain injury requiring invasive ICP monitoring will undergo bedside ONUS, with blinded ONSD measurement by an expert investigator. The image analysis algorithm will then be used to measure ONSD and accuracy determined compared to the "reference standard" expert measurement.
Concussion in Motor Vehicle Accidents: The Concussion Identification Index
Motor Vehicle AccidentsTBI (Traumatic Brain Injury)12 moreThe primary goal of this study is to provide clinicians with a brief, patient self-administer instrument yielding a single composite score that reliably correlates with objective findings on standardized neurocognitive assessment for concussion.
Rapid Diagnostics for Traumatic Brain Injury (TBI)
Traumatic Brain InjuryNovel biomarkers of traumatic brain injury (TBI) have been discovered in laboratory animal models. The objective of this study is to find whether similar markers are detectable in the body fluids of human subjects that have sustained a TBI.
Photobiomodulation for Concussions: the Use of the ImPACT® Test as an Assessment Tool
Mild Traumatic Brain InjuryBrain photobiomodulation (PBM) therapy is an innovative modality for the stimulation of neural activity in order to improve brain function and is currently under investigation as a treatment for several diverse neurological disorders. Our emphasis on this study is to review the use of PBM as a treatment modality for concussions and the use of ImPACT® (Immediate Post-Concussion Assessment and Cognitive Testing) test to assess improvement in cognition and symptomatology in patients with post-concussion syndrome (PCS) treated with PBM.
Questionnaire for the Evaluation of Anger, Hostility and Aggression After Acquired Brain Injury....
Cerebral LesionThe incidence of aggression and violent behavior is usually reported to be high after acquired brain injury, around 54%. Behaviors with verbal agression and, less frequently, physical agressions, are described. These behaviors may be linked to the dysfunction of the frontal lobes responsible for executive functions and complex social interactions, or to the dysfunction of the temporal structures that may also be responsible for increased aggression. It is interesting to note that very few scales or specific questionnaires evaluate the factors and co-variables that could lead to aggressive behavior after an acquired brain injury. Such questionnaires are very rare, and none have been validated in French. The objective of this study is to develop a questionnaire in French that aims to assess anger, hostility and aggression after acquired brain injury. The psychometric qualities of this questionnaire will be evaluated using the Rasch probabilistic model. The development of such a tool will be of major interest for clinical practice and future clinical research.

Balance and Mild Traumatic Brain Injury (TBI)
Brain ConcussionTraumatic Brain InjuryThe purpose of this pilot project is to determine whether using one inertial sensor on the waist during routine clinical balance testing (i.e. Balance Error Scoring System (BESS)), will be a more immediate, objective, reliable and sensitive way to measure and quantify balance deficits in individuals with mild Traumatic Brain Injury (mTBI).
