Active clinical trials for "Brain Injuries, Traumatic"

Utility of transcranial Doppler as an Early Predictor of Neurological deterioration in Mild and Moderate Traumatic Brain Injury

The goal of this experimental observation study is to figure out differently expressed biomarkers in body fluid in traumatic brain injury 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? Participants will be treated by emergency operation, and their body fluid samples will be collected in emergency room and during the operation.

Background: Traumatic brain injury (TBI) affects over 1.7 million people in the United States each year. Many cases are mild, but people with a history of TBI may have long-term symptoms; they are also known to be more susceptible to future concussions. Researchers are working to understand how TBI affects tissues in and around the brain over the long term. This natural history study will investigate how a TBI may change the stiffness of the brain and its surrounding connective tissues. Objective: To see how the brain and connective tissues respond to small head movements in people with and without a prior TBI. Eligibility: People aged 21 to 65 years with a history of TBI. People with no history of TBI are also needed. Design: Participants will have 1 clinic visit that will last about 4 hours. Participants will have a physical exam. They answer questions to make sure it is safe for them to have a magnetic resonance imaging (MRI) scan of their brain. They will have an MRI scan in 2 parts. During the first part, participants will lie on a table that slides into a large tube. They will hear loud knocking noises. They may wear earplugs or earmuffs. They will lie still for 15 minutes at a time. They will be in the tube for about up to 75 minutes. The second part is called magnetic resonance elastography (MRE). Participants will lie with their head on a pillow that vibrates gently. This test will take 10 minutes. Participants will answer questions about how they feel 1 or 2 days after the procedure.

Clinical evaluation is crucial in the clinical diagnosis, treatment, and prognosis prediction in patients with traumatic brain injury (TBI). However, the existing evaluation systems are not perfect, because many factors are not taken into account, for example, there is a lack of molecular diagnostic criteria for evaluating patients with TBI. We attempt to collect the patient's clinical data and combine it with neuroimaging, as well as molecular biomarkers generated by single-cell sequencing to assess their neurological status and outcome. The clinical and molecular data collection and analysis will be helpful to evaluate the patient's neurological condition and predict the patient's outcome more accurately.

We aim to acquire data using DCS on patients who are undergoing invasive ICP and ABP monitoring on ITU as part of their normal treatment. Data will then be correlated to derive various parameters including CBF and BFI. All interventions are entirely non-invasive.

The purpose of this observational epidemiological study is to investigate the management and the complications associated with severe trauma. Data will be analysed to answer pre-defined scientific projects and to improve management of these conditions.

Traumatic Brain Injury (TBI) is a common injury in combat, terrorist attacks and sports such as football and hockey. Unnecessary delays in the diagnosis and treatment of brain damage in patients who can benefit from evacuation procedures can lead to worse brain injury, worse outcome and, sometimes, unnecessary death. However, there is no reliable and sensitive method for diagnosis of TBI severity in the field. In this study we will examine the feasibility of using this a multifocal chromatic pupillometer for monitoring TBI, by examining the pupillary response to multifocal chromatic stimuli in intracranial pressure (ICP)-monitored severe TBI patients. As control, normal subjects will be tested for pupillary responses using this device.

The goal of this clinical trial is to evaluate the effects of Lifebloom One in people who have suffered a stroke or a traumatic brain injury. The main questions to be answered are: Does Lifebloom One allow users to spend more time standing each day? Does Lifebloom One allow users to improve their balance and gait? Participants will use Lifebloom One during 8 weeks. For each participant, gait and balance are compared either with and without Oxilio or before and after Lifebloom One intervention.

The investigators previously developed a virtual 14-day dual-task walking exercise program and tested its feasibility with individuals with mild traumatic brain injury (mTBI) history. The investigators will test the feasibility and efficacy of a mobile app-version (Uplode) of the same 14-day exercise program (Brain & Walk Exercise Every Day [BraW-Day]), on cognition, sensorimotor, and other functions in a group of voluntary young adults with an mTBI between last three months to two years, including student athletes, Veterans, and ethnic minorities.

Traumatic brain injury (TBI) is a major public health concern, particularly among older adults (OAs) ≥ 65 years of age. Each year in the United States, TBI results in over 600,000 emergency department visits and hospitalizations among OAs. Mild TBI (mTBI) accounts for 80% of all TBI in OAs and is quite understudied in this rapidly growing population. mTBI, is mild in name only, as it can result in dysfunction in multiple cognitive domains, including attention, processing speed, executive functioning and memory and has been shown to be associated with progressive brain atrophy and increased susceptibility to neurodegenerative disorders. Cognitive rehabilitation therapy is an evidence-based approach that can successfully improve cognitive impairment following TBI. Virtual reality (VR) is emerging as a technology that can assess cognitive impairment and provide a neurorehabilitation modality (NRM) to improve cognitive decline post TBI. Not only can VR provide a variety of environments like those encountered in real life and be adapted to varying levels and types of cognitive disability, but it can also be used safely in a patient's home with minimal equipment. Yet, despite the promise of cognitive rehabilitation using VR among OAs, very few studies to date have assessed the efficacy of VR cognitive rehabilitation in TBI. The aim of this study is to assess the effect and collect data on the efficacy and feasibility of a virtual reality application as a neurorehabilitation modality on executive functioning (attention, immediate memory, and visual-spatial skills) in OAs with mTBI. The hypothesis is that The use of VR mediated cognitive exercises post mTBI will be associated with improved executive function at 6-weeks post-randomization compared to the control group.
