Defining Axonal Injury in Children With Mild Traumatic Brain Injury
Traumatic Brain InjuryTo measure Axonal Injury in children with mild traumatic brain injury enrolled in an Emergency Department using Diffusion Tensor Imaging, a type of MRI and biomarkers.
Mechanical Ventilation in Brain-injured Patients
Brain-injuryStroke3 moreProtective ventilation (association of a tidal volume < 8 ml/kg with a positive end expiratory pressure) is poorly used in severe brain-injured patients. Moreover, a systematic approach to extubation may decrease the rate of extubation failure and enhance outcomes of brain-injured patients. We hypothesized that medical education and implementation of an evidence-base care bundle associating protective ventilation and systemic approach to extubation can reduce the duration of mechanical ventilation in brain-injured patients.
The Head Injury-associated Photosensitivity and Pupillary Function (HIPP) Study
Head InjuryTraumatic Brain Injury (TBI)2 moreAfter a head injury, many people find that exposure to light causes them increased discomfort. By measuring how the pupil in the eye constricts to flashes of red and blue light, this study will investigate whether this phenomenon is due to a change in the eye's sensitivity to light.
Non-blinded Data Collection Study of Concussion Using the BrainPulse(TM)
Brain ConcussionMild Traumatic Brain InjuryThe multi-center study evaluates BrainPulse recordings from subjects with a suspected or confirmed concussion to improve a concussion detection algorithm. Subjects may also consent for a 5 additional follow-ups over a 21-day period to compare the progression of change in their BrainPulse recordings.
Evaluation of Biomarkers of Traumatic Brain Injury
Traumatic Brain InjuryThe primary objective of this study is to evaluate the utility of the Banyan UCH-L1/GFAP Detection Assay as an aid in the evaluation of suspected traumatic brain injury (Glasgow Coma Scale score 9-15) in conjunction with other clinical information within 12 hours of injury to assist in determining the need for a CT scan of the head.
Imaging of Traumatic Brain Injury
Traumatic Brain InjuryThis project aims to study the prognostic ability of various MRI imaging markers in the evaluation of TBI patients. Cognitive, social, and occupational recovery will be measured at each time point, and compared to MRI findings. Healthy volunteers will serve as a comparison to the TBI patients. It is hypothesized that novel MRI markers of metabolism, hemodynamics, functional connectivity, and tissue microstructure will be related to the clinical status of the patient, as well as their social and occupational outcomes.
Cerebral Blood Flow (CBF) Disturbances Following Traumatic Brain Injury (TBI) and Subarachnoid Hemorrhage...
Traumatic Brain InjurySubarachnoid HemorrhageIt is a "proof of concept" study, aimed to evaluate whether the "optimal CPP", defined by the best PRx, corresponds to the acceptable CBF values in patients affected by CBF disfunction caused by TBI or SAH.
Observational Study of Cortical Spreading Depression in Human Brain Trauma
Traumatic Brain InjurySince the primary damage from traumatic brain injury (TBI) is irreversible, the focus of medical management of TBI is preventing secondary injury that can be life-threatening and worsen patient outcome. Insight into the pathologic mechanisms of secondary injury, which are largely unknown, is required for developing better treatments. In preliminary studies, the investigators have found that a pathologic brain activity, known as spreading depression, recurs in a large number of TBI patients in the first week after injury. Spreading depressions are short-circuits of brain function that arise spontaneously from an injury and spread repeatedly as waves into neighboring brain tissue. Animal research has shown that spreading depressions can cause secondary injury to the brain. The primary objective of this observational study is to determine whether the occurrence or severity of spreading depression is related to worse neurologic recovery from TBI. Results from the study will determine whether monitoring of spreading depression should be used as a guide or target for improved medical management of the TBI patient.
Dynamic and Static Autoregulation After Brain Injury
Acute Brain InjuriesTBI (Traumatic Brain Injury)1 moreThe aim of the study assesses static and dynamic cerebrovascular autoregulation daily over one week in patients with traumatic brain injury or intracranial hemorrhage to quantify the temporal profile of the autoregulatory status.
Executive Dysfunction & Suicide: An Exploration Of Risk Factors In Traumatically Brain Injured Veterans...
Traumatic Brain Injury (TBI)Suicidal BehaviorThis is a study to learn more about traumatic brain injury (TBI) and suicidal behaviors. The purpose of this research is to find out more about the issues related to these conditions. This study seeks to explore the relationship between executive dysfunction and suicidal behavior in an outpatient population.
