Active clinical trials for "Brain Injuries, Traumatic"

The investigators will obtain thromboelastography (TEG) on pediatric patients admitted to the Rady Children's Hospital ICU after traumatic brain injury on admission to our ICU and after 24 hours of care. The investigators hypothesize that TEG will identify abnormalities of coagulation that are not identified by traditional coagulation studies, i.e. prothrombin time (PT), activated partial thromboplastin time (aPTT), and international normalized ratio (INR).

It is hypothesized that the long-term results of rehabilitation and subsequent aging after Brain Trauma depend on brain's premorbid anatomical (structural) and functional (cognitive, emotional) reserves. The purpose of this study are: to determine whether such reserves exist. to study their convergent and discriminant validity. to study their characteristics.

The PreTBI II study aims to investigate the diagnostic potential of prehospital S100B and GFAP measurements in prediction of need for neurosurgical observation and/or intervention in moderate TBI patients, to rule-in high-risk patients. Ultimately to select patients who will benefit from neuro surgical expertise in specialized departments and thereby possibly better patient outcome. Hopefully also minimize treatment delay, secure optimal resource consumption and streamline patient courses by predicting the presence of neurotrauma. Hypotheses: A prehospital serum S100B level > 0,10 microgram/L and expectedly above a certain and currently unknown cut-off value indicates the need for neurosurgical observation and/or intervention in moderate TBI patients. A prehospital serum GFAP level above a certain and currently unknown cut-off value can significantly predict a need for urgent neurosurgical observation and/or intervention in moderate TBI patients. Biomarker dynamics between prehospital and in-hospital biomarker values of S100B and GFAP can significantly predict a need for urgent neurosurgical observation and/or intervention. Biomarker dynamics between prehospital and in-hospital biomarker values of S100B and GFAP can significantly predict hospital course and outcome of patients with moderate TBI.

This 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.

The aim of the study is to investigate whether dexmedetomidine could suppress catecholamine release into peripheral blood to prevent PSH attacks and to achieve neuroprotection.

The purpose of this study is to assess cognitive function using a rapid, portable, computerized neurocognitive testing device in a wide variety of clinical settings.

Optic 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.

The 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.

Novel 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.

Brain 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.
