Filter by:This study evaluates the feasibility of an experimental protocol that combines advanced multi-modal imaging of the brain with clinical and behavioural scales to characterise the neural, behavioural, and clinical effects of transcranial direct current stimulation (tDCS) for rehabilitation in PDOC
The E-TIPS trial will evaluate an evidence-based, telehealth pain self-management intervention compared to standard care (a waitlist) for chronic pain in adults with physical disabilities who are employed. Participants from anywhere in the US will be randomized to either E-TIPS, a cognitive-behavioral pain self-management intervention delivered by telephone, or a waitlist control. Outcomes, including pain interference, will be assessed at baseline, mid-treatment, post-treatment, and 6-month follow up.
Researchers are trying to assess how accurately and safely NIRS non-invasive monitoring can detect changes in intracranial pressure to determine if this noninvasive device can be used instead of invasive monitoring with Licox in the future.
With an average of 21,000 diagnosed brain injuries each year among military personnel, traumatic brain injury (TBI) remains a major health concern for the United States Military Health System. Mild traumatic brain injury (mTBI) is the most common type of brain injury sustained by military personnel and may result in chronic cognitive impairment.Unfortunately, many service members (SMs) have a history of multiple head injuries as well as psychological co-morbidities that negatively influence recovery. Advances in treatment options for cognitive rehabilitation following mTBI have been of increasing interest to the medical community and may increase treatment efficacy for injured SMs to ensure force readiness. Cognitive Rehabilitation (CR) for severe brain injury focuses on compensatory strategies for activities of daily living such as using lists to remember grocery items or reminders to take medications and attend medical appointments. Research has shown CR interventions to have considerable effectiveness in the acute and sub-acute phase of recovery after severe TBI. But there is insufficient evidence that they improve rates of individuals returning to work, independence in activities of daily living (ADL), community re-integration, or quality of life.
Studies in patients with disorders of consciousness (DOC) after severe brain injury implicate dysfunction of the anterior forebrain mesocircuit dysfunction a key underlying mechanism. The anterior forebrain metabolism in DOC is markedly downregulated across brain regions underpinning highly elaborated cognitive behaviors demonstrating a collapse of the level of synaptic background activity required for consistent goal-directed behavior and arousal regulation. Since dopamine levels are one of the primary controllers of the level of synaptic background activity within these forebrain structures and in regulating excitatory glutamatergic homeostasis, the investigators propose to investigate the specific contribution of presynaptic dopamine function in glutamatergic neurotransmission in posttraumatic DOC. The aim of the present study is to measure metabotropic glutamate receptors 5 occupancy in the main gutamatergic structures of the brain using (3-[18F]fluoro-5-(2-pyridinylethynyl)benzonitrile)-positron emission tomography ( [18F]FPEB-PET) at rest and following a short pharmacological challenge with amantadine, an N-methyl-D-aspartate receptor (NMDA-R) antagonist, following L-DOPA, and amantadine + L-DOPA. Using this novel technique in DOC the investigators will characterize the relevance of a presynaptic deficiency to synthesize and/or release dopamine in the final regulation of excitatory interneurons of the anterior forebrain mesocircuit. It is unknown whether glutamatergic neurotransmission is affected across the population of subjects with DOC and, if this condition is secondary to a presynaptic dopaminergic failure of the anterior forebrain mesocircuit (i.e., down-regulation). Since the investigators previously identified the existence of a presynaptic dopaminergic deficit in these subjects due to a failure in the biosynthesis of dopamine, the investigators will evaluate if by providing the main biological substrate of the biosynthesis process (i.e., L-DOPA) the glutamatergic system regains homeostasis. The investigators therefore propose to investigate patients with posttraumatic DOC using [18F]FPEB-PET at rest and following short pharmacological challenges aimed at increasing glutamate and dopamine release.
The aim of this study is to develop exercise prescription of TBI patients and then to evaluate the effectiveness of programmed aerobic walking exercise to improve cognitive performance, depression relief, motivation, symptom, resilience and quality of life with improvement of CBF. This will be a randomized controlled clinical trial, using a mixed method to explore the feasibility and validity of such a safety exercise prescription. Then, a randomized clinical control trial will be applied in TBI patients to evaluate the effectiveness of programmed aerobic exercise to promote psysical-psycho-social health such as cognitive status, 6 minutes walk test, depression relief, motivation, symptom, resilience and quality of life.
Various methods have been studied to evaluate autoregulation. However, there is currently no universally accepted technique to assess integrity of the cerebral autoregulation neurovascular system. In the last decade, significant progress has been achieved in developing methods to assess cerebral autoregulation by quantifying cross-correlation between spontaneous oscillations in CBF or oxygenation and similar oscillations in arterial blood pressure. In this study the investigators will analyze the relationship between spontaneous fluctuations in mean arterial blood pressure and cerebral blood flow velocity or cerebral regional oxygenation to investigate two novel methods for measuring cerebral autoregulation, Transfer Function Analysis and Wavelet Coherence after acute pediatric brain injury.
evaluate the impact of Doxycycline on both clinical outcome and blood levels of NSE in patients with TBI.
The purpose of this research study is to evaluate the effectiveness of "RehaCom," a computerized treatment for memory deficits, in a 16-session, interactive course. Following a manualized approach, the Rehacom modules will be used for the repeated application of the content acquired during 1-on-1 memory strategy training. The goal is to improve face/name, list and verbal memory of patients who survived a moderate to severe traumatic brain injury.
Transcranial electrical stimulation (tES) is a non-invasive form of brain stimulation that has previously been to shown to have therapeutic potential in traumatic brain injury (TBI) patients. In this study, the study team will use a brain activity monitor (electroencephalogram, EEG) and a computer-based task to observe the effects of different forms of tES, like transcranial direct current stimulation (tDCS) and transcranial pulsed current stimulation (tPCS), on impulse control and sustained attention in people with TBI. Additionally, the study team will measure how much tDCS and tPCS affect the brain activity of a specific area of the brain associated with impulse control and attention. Problems with response inhibition have been shown to make rehabilitation more difficult for people with TBI. It also reduces social functioning and can also negatively affect job performance, which ultimately lead to a decreased quality of life. A better understanding of the effects of tES in TBI patients could be informative in finding out what its therapeutic potential is for this population.
