Active clinical trials for "Brain Injuries, Traumatic"

This protocol is aimed at collecting oculomotor response data from a variety of brain injuries and impairments, and to secondarily evaluate the functionality and ease of use of the NeuroTriage device in the ED in patients with any presumed brain injury and/or impairment. For example, prior studies in adolescents with a concussion have shown that they tend to overshoot the pattern when asked to follow the movement of the lights in the binoculars

Mild traumatic brain injury (mTBI) is one of the most common reasons behind emergency department (ED) visits. A small portion of mTBI patients will develop an intracranial lesion that might require neurosurgical intervention. Several guidelines have been developed to help direct these patients for head Computerized Tomography (CT) scanning, but they lack specificity, mainly focus on ruling out lesions, and do not estimate the risk of lesion development. The aim of this retrospective observational study is to create a risk stratification score that predicts the likelihood of intracranial lesion development, lesion progression, and need for neurosurgical management in patients with mTBI presenting to the ED. Eligible patients are adults (≥ 15 years) with mTBI (defined as admission Glasgow Coma Scale (GCS) 13-15) who presented to the ED within 24 hours of injury to any ED in Stockholm, Sweden between 2010-2020. Reasons for ED visit and Internal Classification of Disease (ICD) codes will be used to screen for patients. Machine-learning models will be applied. The primary outcome will be a traumatic lesion on head CT, defined as a cerebral contusion, subdural haematoma, epidural haematoma, subarachnoid haemorrhage, intraventricular haemorrhage, diffuse axonal injury, skull fracture, traumatic infarction or sinus thrombosis. The secondary outcomes will be any clinically significant lesion, defined as an intracranial finding that led to neurosurgical intervention, discontinuation or reversal of anticoagulant or antiplatelet medication, hospital admission > 48 hours due to the TBI, or death.

The investigators will carry out multi-center and large sample research based on the Chinese population, screen the optimal diagnostic and prognosis recognition biomarkers and analyze the diagnostic critical cutoff values in patients with mild to moderate traumatic brain injury, so as to provide a substantial basis for clinical diagnosis and prognosis recognition.

The study aims to identify factors that predict the medium and long-term outcome of patients with disorders of consciousness (DOC) undergoing early neurological rehabilitation. In this prospective, observational study, 130 DOC patients are going to be included (36 months). At study entry, different routine data, disease severity and functional status are documented for each patient. In addition, MRI, EEG and evoked potentials are measured within the first week. The level of consciousness is recorded with the Coma-Recovery-Scale-Revised and serves as the primary outcome parameter. Complications, comorbidities, functional status and leve of consciousness are assessed weekly. After eight weeks, the measurement of the MRI, the EEG and the evoked potentials are repeated. After 3, 6 and 12 months, the Glasgow Outcome Scale-Revised is used to followed up the current status of the patients.

This is an observational study in neurocritical care units at University of California San Francisco Medical Center (UCSFMC), Zuckerberg San Francisco General Hospital (ZSFGH), and Duke University Medical Center. In this study, the investigators will primarily use the monitor mode of the Transcranial Doppler (TCD, non-invasive FDA approved device) to record cerebral blood flow velocity (CBFV) signals from the Middle Cerebral Artery and Internal Carotid Artery. TCD data and intracranial pressure (ICP) data will be collected in the following four scenarios. Each recording is up to 60 minutes in length. Multimodality high-resolution physiological signals will be collected from brain injured patients: traumatic brain injury, subarachnoid and intracerebral hemorrhage, liver failure, and ischemic stroke. This is not a hypothesis-driven study but rather a signal database development project with a goal to collect multimodality brain monitoring data to support development and validation of algorithms that will be useful for future brain monitoring devices. In particular, the collected data will be used to support: Development and validation of noninvasive intracranial pressure (nICP) algorithms. Development and validation of continuous monitoring of neurovascular coupling state for brain injury patients Development and validation of noninvasive approaches of detecting elevated ICP state. Development and validation of approaches to determine most likely causes of ICP elevation. Development and validation of approaches to detect acute cerebral hemodynamic response to various neurovascular procedures.

Early prediction of outcomes after acute brain injury (ABI) remains a major unsolved problem. Presently, physicians make predictions using clinical examination, traditional scoring systems, and statistical models. In this study, we will use a novel technique, "SeeMe," to objectively assess the level of consciousness in patients suffering from comas following ABI. SeeMe is a program that quantifies total facial motion over time and compares the response after a spoken command (i.e. "open your eyes") to a pre-stimulus baseline.

Children are known to have devastating impact from traumatic brain injury (TBI). The focus of treatment of severe TBI is to limit secondary insult which can aggravate brain injury and worsen outcome and is supported by monitoring brain pressure (ICP) and arterial pressure (ABP). These pressures, if incorporated in Multi-modality monitoring can be used to interpret state of mechanisms used by brain to maintain normal blood flow. This has been advised to guide management of severe TBI in adults, however, there is limited experience with advanced brain monitoring in children. The investigators propose to study the use of this in children with severe TBI. Children (up to 16 years of age) with a severe TBI are referred to a neurosurgical unit (NSU) and admitted to a paediatric intensive care unit (PICU) as part of usual NHS clinical practice. All patients with a severe TBI require a monitoring wire to be inserted into the brain to read the pressure inside the skull and a similar device in an artery to monitor the blood pressure. These recordings are documented by a PICU nurse at a prescribed frequency. Without interrupting this clinical practice investigators propose to record these values using computer software called ICM+. These recordings will provide real time analysis and a continual recording of important parameters which will provide the study with much needed information on the patterns of pressures in the brain after this injury in children. All patients will be followed up for 12 months to see how well they recover, neuropsychology assessment will be performed by a Neuropsychologist at the recruiting centre using a standardised form.

The goal of this experimental observation study is to figure out differently expressed biomarkers in lesion tissues in traumatic brain injury or hypertension intracranial hemorrhage patients. The main questions it aims to answer is: Which RNA, protein and metabolites are differently expressed in lesion tissues? What molecular mechanism is participated in TBI or ICH? Participants will be treated by emergency operation, and their lesion tissues will be collected during the operation.

In this study, it is aimed to determine the prognostic value of GCS-P and the GCS-P score, which is formed by assigning a verbal score, in patients with traumatic brain injury, where all parameters can be evaluated. In the model to be created, a new total score will be obtained with Motor score + Eye Response + assigned verbal Score-Pupil score and this score will be compared with GCS and GCS-Pupil score.

The study population will consist of 3 mutually-exclusive sets of patients and subjects: TBI patients with intracranial bleeding TBI patients without intracranial bleeding Control subjects with normal brain health. Research subjects between the ages of 22 to 50 will be enrolled. All TBI patients must have a diagnostic head CT scan within 24 hours of the injury. TBI patients without intracranial bleeding based on the CT scan must have a Glasgow Coma Scale (GCS) score at enrollment of ≤ 14. Total maximum duration of active monitoring with the device in this study is 48 hours with a clinical follow-up at day 7 after enrollment.
