Filter by:Intracranial pressure (ICP) monitoring is the most common neuromonitoring modality used in neurocritical care units (NCCU) around the world. Uncertainties remain around intracranial pressure monitoring both in traumatic and non-traumatic brain injury, and variation in clinical practice of intracranial pressure monitoring exists between neurocritical care units. The objectives of the study will explore intracranial pressure monitoring variation in practice to prioritise uncertainties in the clinical management of critical care patients with acute brain injury and support further collaborative hypotheses-based prospective studies.
The purpose of this research study is to collect data from the eyes of traumatic brain injury (TBI) patients. Patients will look at a green target that will measure the fixation of the eye for 30 seconds. In that 30 seconds, the location of the green target will change and the participant is to track, with their eyes, the light as best they can. The device will measure how well fixation was maintained and the speed of the saccadic movements of the eye. Data will then be used to determine whether there is correlation between these measures and known TBI.
This study evaluates the validity of an intravascular continuous glucose monitoring microdialysis probe, and compares the values to routinely inserted cerebral glucose microdialysis to evaluate the hypothesised relationship between intracranial and intravascular glucose levels.
mTBI is a leading cause of sustained physical, cognitive, emotional, and behavioral deficits in OEF/OIF/OND Veterans and the general public. However, the underlying pathophysiology is not completely understood, and there are few effective treatments for post-concussive symptoms (PCS). In addition, there are substantial overlaps between PCS and PTSD symptoms in mTBI. IASIS is among a class of passive neurofeedback treatments that combine low-intensity pulses for transcranial electrical stimulation (LIP-tES) with EEG monitoring. Nexalin is another tES technique , with FDA approvals for treating insomnia, depression, and anxiety. LIP-tES techniques have shown promising results in alleviating PCS individuals with TBI. However, the neural mechanisms underlying the effects of LIP-tES treatment in TBI are unknown, owing to the dearth of neuroimaging investigations of this therapeutic intervention. Conventional neuroimaging techniques such as MRI and CT have limited sensitivity in detecting physiological abnormalities caused by mTBI, or in assessing the efficacy of mTBI treatments. In acute and chronic phases, CT and MRI are typically negative even in mTBI patients with persistent PCS. In contrast, evidence is mounting in support of resting-state magnetoencephalography (rs-MEG) slow-wave source imaging (delta-band, 1-4 Hz) as a marker for neuronal abnormalities in mTBI. The primary goal of the present application is to use rs-MEG to identify the neural underpinnings of behavioral changes associated with IASIS treatment in Veterans with mTBI. Using a double-blind placebo controlled design, the investigators will study changes in abnormal MEG slow-waves before and after IASIS treatment (relative to a 'sham' treatment group) in Veterans with mTBI. For a subset of participants who may have remaining TBI symptoms at the end of all IASIS treatment sessions, MEG slow-wave changes will be recorded before and after additional Nexalin treatment. In addition, the investigators will examine treatment-related changes in PCS, PTSD symptoms, neuropsychological test performances, and their association with changes in MEG slow-waves. The investigators for the first time will address a fundamental question about the mechanism of slow-waves in brain injury, namely whether slow-wave generation in wakefulness is merely a negative consequence of neuronal injury or if it is a signature of ongoing neuronal rearrangement and healing that occurs at the site of the injury.
Patients who experience lung injury are often placed on a ventilator to help them heal; however, if the ventilator volume settings are too high, it can cause additional lung injury. It is proven that using lower ventilator volume settings improves outcomes. In patients with acute brain injury, it is proven that maintaining a normal partial pressure of carbon dioxide in the arterial blood improves outcomes. Mechanical ventilator settings with higher volumes and higher breathing rates are sometimes required to maintain a normal partial pressure of carbon dioxide. These 2 goals of mechanical ventilation, using lower volumes to prevent additional lung injury but maintaining a normal partial pressure of carbon dioxide, are both important for patients with acute brain injury. The investigators have designed a computerized ventilator protocol in iCentra that matches the current standard of care for mechanical ventilation of patients with acute brain injury by targeting a normal partial pressure of carbon dioxide with the lowest ventilator volume required. This is a quality improvement study with the purpose of observing and measuring the effects of implementation of a standard of care mechanical ventilation protocol for patients with acute brain injury in the iCentra electronic medical record system at Intermountain Medical Center. We hypothesize that implementation of a standardized neuro lung protective ventilation protocol will be feasible, will achieve a target normal partial pressure of carbon dioxide, will decrease tidal volumes toward the target 6 mL/kg predicted body weight, and will improve outcomes.
Chronic Traumatic Brain Injury (cTBI) symptoms exist in individuals who experienced previous traumatic brain injuries. There are 80-90 thousand individuals who are clinically diagnosed with cTBI, with estimated costs at greater than 60 billion dollars. However, there is a lack of studies using comprehensive diagnostic imaging tools to better understand physiological ramifications of the injury that may help guide therapy. This study uses integrative medicine approaches for persons with cTBI. Another aim of this study will be a continuation of this protocol in an effort to address the ongoing distressing physiological and psychological (anxiety and depression) symptoms associated with cTBI. After completion of the initial 3 study arms, the investigators have amended the protocol to evaluate the physiological and psychological effects and potential symptom improvement of integrative medicine approaches in cTBI patients using the Neuro Emotive Technique (NET). Participants may be re-enrolled in the NET group after completion of participation in the initial study arms. The participants in the NET substudy will be interviewed about Subjective Units of Distress (SUDS) associated with the cTBI event initially and after completion of the NET sessions.
This research is a randomised controlled study. The study hypothesis is cognitive rehabilitation for attention deficits following mild traumatic brain injury will improve patient's cognitive outcome, measured by neuropsychological and neuroimaging parameters. Participant recruitment is from University Malaya Medical Centre, Malaysia. All mild traumatic brain injury participants have to fulfil the study inclusion criteria and written consented for therapy. Control group receives existing patient-centred cognitive treatment whereas intervention group receives individualised structured cognitive rehabilitation therapy. The intervention begins at three months post injury and ends at six months post injury. Study outcome measurements are applied at pre and post treatment. This study was ethically approved by Medical Research Ethics Committee University Malaya Medical Centre (MREC ID NO: 2016928-4293).
This study aims to develop and evaluate biomarkers using non-invasive optical coherence tomography (OCT) and OCT angiography (OCTA) as well as ultra-widefield (UWF) fundus photography to assess the structure and function of the retinal and choroidal microvasculature and structure in persons with mild cognitive impairment (MCI) and Alzheimer's Disease (AD), Parkinson's Disease (PD), or other neurodegenerative disease, diseases as outlined.
Approximately 15-20% of patients diagnosed with a concussion/mild traumatic brain injury (mTBI) have persistent symptoms that continue up to six months or longer. Typical problems identified by these patients include difficulty with memory, multi-tasking, the ability to complete tasks quickly, and higher executive functions (e.g., inhibition, initiation, insight, motivation) (Belanger & Vanderploeg, 2005; Mott, McConnon, & Rieger, 2012, Rabinowitz & Levin, 2014). If these symptoms persist they can not only affect thinking, but also communication abilities (e.g., verbal and nonverbal interactions, reading, and writing) (ASHA, 2007). Therefore, it is hypothesized that screening measures that evaluate both thinking and communication can better identify individuals at-risk for persistent symptoms at two week and four weeks post-injury. Also, if cognitive-communication therapy was administered earlier post-injury, then outcomes related to return to daily activities, work, and/or the academic setting could possibly change. This study intends to investigate the use of cognitive and communication screening measures for the identification of persistent symptoms and the provision of early cognitive-communication therapy if problems persist.
Abstract Objective: Investigators examined the feasibility of applying a participation-focused strategy training intervention to community-dwelling adults with cognitive impairments following stroke and brain injury and evaluated its potential effect on participation. Method: Participants with a diagnosis of stroke or brain injury participated in this single-group, repeated-measures study. Participants received 1~2 sessions of strategy training intervention weekly for 8~18 sessions. Outcome measures included the Participation Measure--3 Domains, 4 Dimensions (PM-3D4D), the Canadian Occupational Performance Measure (COPM), and feasibility indicators (participants' recruitment, retention, attendance, engagement, comprehension, satisfaction, and intervention adherence).
