Active clinical trials for "Brain Injuries"

This study evaluates the impact of platelet transfusion on geriatric patients with platelet dysfunction from Traumatic Brain Injury. The authors hypothesize that patients will recover better if their platelet dysfunction is corrected with platelet transfusion.

mTBI is widely recognized as a major public health concern in the United States and worldwide. mTBI diagnosis remains a clinical challenge as no single test can diagnose every concussion. Recent advances in EEG evoked response potential analysis have led to a novel technique for assessing brain network activation (BNA) patterns. This study purpose is to study this BNA technology in individuals who have sustained a concussion.

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.

Decompressive craniectomy is a treatment of refractory intracranial hypertension after various etiologies : malignant ischemic stroke, traumatic brain injury, intraparenchymal hemorrhage, aneurysmal subarachnoid hemorrhage, cerebral venous thrombosis. Initially considered as a lifesaving therapy, benefits in terms of survival were shown compared to medical treatment alone. However, despite a better survival, morbidity and poor neurological outcome are frequent among survivors. The objective of the study is to identify initial good neurological outcome factors after decompressive craniectomy in a large series of patients, in order to argue surgical and intensive care decisions, considering expected benefit and quality of life.

The study aims: to observe a population particularly exposed by the past to brain trauma and concussion: Motorsport Pilots who are retired from a professional practice of motor sport; to report results of their neuro-cognitive evaluations, to determine if specific profiles emerge. to evaluate potential consequences of these traumas' history at a cerebral, physical and psychological level. to evaluate the contribution of the various examinations performed as part of a concussion assessment in routine care (eye-tracking, brain imaging, Neuropsychological Assessment).

The aims are: Investigate new magnetic resonance imaging (MRI) scans for diagnosing severe nerve injury in the arm. Understand how the brain and spinal cord respond to severe nerve injury using MRI. The nerves which control movement and feeling in the arm can be severely damaged in eg. motorbike crashes, sporting or work-related injuries. Every year 500 adults sustain life-changing major nerve injuries, causing 1) disability needing constant care, 2) life-long pain and 3) mental illness. In England, major nerve injuries cost £250million every year in hospital treatments, unemployment and social care. Injured nerves can be repaired with surgery. To decide if nerves need repairing, exploratory surgery is needed. Instead, we have developed a new MRI scan which could diagnose nerve injuries, meaning that exploratory surgery could be avoided, nerve injuries could be diagnosed sooner and reconstructive surgery performed sooner. Some people with nerve injuries develop lifelong pain - if we could understand how the brain adapts, we could learn how to prevent nerve pain. Also, some people don't recover movement in their hand - if we could understand how the brain reorganises nerves controlling movement, we could predict who would benefit from surgery.

Sedation and analgesia is necessary management for patients in the intensive care units. The high-level studies of sedation and analgesia in China are still deficient, especially in patients with brain injuries who even have been excluded from the relevant studies.

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.

Traumatic brain injury (TBI) is a leading cause of post-injury hospitalization, disability, and death worldwide. In Nova Scotia, approximately 50% of major trauma reported is head trauma. TBI is predicted to be the most common and expensive neurological condition in Canada through the year 2031. Families and medical teams must often decide on the appropriate level of care for patients with severe TBI and frequently need to consider withdrawal of life support measures. These decisions have implications for patients with severe TBI, costs to the health care system, and rates of organ donation. A reliable method for neurological evaluation at the time of the patient's arrival to the hospital is important, because it is possible that many patients with severe TBI already have permanent brain damage. Assessing this brain damage with clinical tests is difficult because of the nature of patients' injuries and the sedative medication they receive at the time of their hospital admission. Current standard imaging technique for these patients is severely limited in the assessment of the extent and severity of the brain damage. Advanced diagnostic imaging, called Computed Tomography Perfusion (CTP), can help detect permanent brain damage. However, CTP of the head is not currently done for patients with severe TBI when they arrive at the hospital. The investigators want to test whether CTP of the head can detect permanent brain damage among patients with severe TBI.
