Active clinical trials for "Brain Injuries"

Concussions (also known as mild traumatic brain injury) are common in young children. In some children, they can lead to short- and long-term difficulties. However, our knowledge of the exact consequences of injuries on young children's brains and behavior is limited. These consequences may be different in children under 6, as their brains are fragile and undergoing significant developmental changes. The aim of this study is to determine the extent to which a concussion sustained before the age of 6 years is associated with changes in young children's brain structure, function and behaviours, using a brain imaging. In this study, the results of a group of 30 children with a concussion will be compared to those of 30 children of the same age with an orthopaedic injury to the upper or lower limbs.

Hypoxic ischemic brain injury (HIBI) is the ensuing brain injury after cardiac arrest and is the primary cause of adverse outcome. HIBI is caused by low oxygen delivery to the brain. The patient's blood pressure is primary determinant of oxygen delivery to the brain. International guidelines recommend maintaining uniform blood pressure targets in all patients, however, this 'one size fits all approach' fails to account for individual baseline differences between patient's blood pressures and extent of underlying disease. Recently, 'autoregulation monitoring', a novel brain monitoring technique, has emerged as a viable tool to identify patient specific blood pressures after brain injury. This personalized medicine approach of targeting patient specific blood pressure (MAPopt) is associated with improved outcome in traumatic brain injury. It has not been evaluated in HIBI after cardiac arrest. Recently, I completed a first-in-human study demonstrating the ability to identify MAPopt in HIBI patients using neuromonitoring (microcatheters inserted into the brain tissue). The proposed study in this grant is to take the next step and investigate the changes in key brain physiologic variables (brain blood flow and oxygenation) before and after therapeutically targeting MAPopt in HIBI patients. This interventional study will serve as the basis to embark on a pilot randomized control trial of MAPopt targeted therapy versus standard of care in HIBI patients after cardiac arrest.

The purpose of this study is to evaluate improvement in balance after receiving physical therapy when augmented by CN-NINM than when augmented by a placebo (sham CN-NINM).

In this study, an FDA-cleared device and type of treatment called "AMES," which stands for Assisted Movement with Enhanced Sensation, will be used to determine whether sensation in the upper limb of individuals with incomplete spinal cord injuries, acquired brain injury, or stroke improves along with movement through treatment. We hypothesize that measureable improvement in the sensation of the upper limb will precede improvement in functional movement.

By collecting multimodal metrics (e.g., clinical factors, neuroimaging, and EEG) in the early phase of severe brain injury (i.e., during the acute hospitalization when a patient has impaired consciousness), and measuring the patients' recovery of consciousness, function, and quality of life in the late phase (at 6 months following the brain injury), we aim to construct an algorithm that synthesizes the results of these metrics to help predict recovery.

Traumatic brain injury (TBI) is a condition that occurs when a mechanical blow to the head causes damage to the brain. The diagnosis of this pathology requires the evaluation of several dimensions, including clinical symptoms, physical signs, cognitive disorders, behavioral and sleep disturbances and state of consciousness. This multidimensional approach provides a comprehensive and accurate assessment of head injury and its severity. The Berlin Consensus of the International Conference on Concussion in Contact Risk Sports held in Berlin in 2016 (McCrory et al., 2017) emphasized that the management of a CTE must be multimodal and multidisciplinary. This expert consensus converged on a tool that is now the most widely used in protocols studying concussion in sports at risk of BTI. This tool, the SCAT 5 (Sports Concussion Assessment Tool), combines symptom assessment, cognitive examination, neurological examination (oculomotricity, balance) and immediate and delayed memory. However, it requires the intervention of a medical expert to assess the clinical signs of the concussed athlete. Hänninen et al (2021) showed that test-retest reproducibility was very good for the clinical symptomatology subscore, but poor or average for the subscores summarizing cognitive tests and balance assessment. Clinicians now need to be able to better assess the severity of damage following head injury, and to monitor the patient's progress. This will improve the management of concussed athletes right up to their eventual return to sporting activity. The ultimate aim of our project is to develop and optimize an easily exportable multimodal concussion assessment tool, based on the use of a virtual reality headset, which will enable us to objectively characterize the state and evolution of a subject after a TCE. This will enable the assessment of neuro-visual functions and compensations in the concussed patient, revealing a higher attentional cost characterized by instability of orthostatic control, higher blink frequency and larger pupil size. The multimodal tool will be built from the results of various tests: Standardized oculomotor tasks(pro-saccades, anti-saccades, smooth pursuit, memory guided saccades, self paced saccades) Orthostatic balance control to assess postural compensations and estimate attentional cost during oculomotor tasks. Pupil dynamics using the Pupil Cycle Time (PCT) test. The aim of this exploratory study is to determine the repeatability of measurements provided by the SPORTiCARE virtual reality headset during different tasks.

The goal of this observational study is to evaluate the performance of UCH-L1 and GFAP combined in patients with a mild traumatic brain injury. The main question : • Does the combination of UCH-L1 and GFAP can exclude brain injuries detected with CT scan in the first twelve hours after a mild traumatic brain injury? Participants will do the exams planed in routine care and : during the expected blood sampling an additional blood sample will be done, seven days after the discharge a call will be done by the investigator.

The goal of this experimental observation study is to figure out differently expressed biomarkers in serum in traumatic brain injury patients, compared with bone fracture patients. The main questions it aims to answer are: Which proteins and metabolites are differently expressed in TBI patients' serum? Which proteins or metabolites can serve as the new serum biomarkers for diagnosing TBI? Participants will be treated by routine treatments, and their serum samples will be collected in the emergency room.

Severe traumatic brain injury (sTBI) is a critical disease of public health importance. Increased intracranial play a significant role in the secondary injury of TBI. Reducing the ICP is helpful in reducing the mortality of sTBI. The threshold of ICP for sTBI has been suggested. The threshold of ICP for sTBI after decompressive craniectomy is not clear.

Historically, participation in clinical trials has been skewed towards certain groups. However, research on the factors that influence participation, both positive and negative, is limited. Brain injury clinical trial patients help us identify these factors by sharing trial experiences during the course of the interventional medical study. This study will include a diverse group of participants to gather a wide range of information on clinical trial experiences. The collected data will then be used to benefit future brain injury patients who are considering participating in a medical study.
