Traumatic Brain Injury Clinical Trials

This study will test a portable virtual reality (VR) system with integrated eye tracking called Virtual Eye Rotation Vision Exercises (VERVE). The proposed VERVE platform will deliver vergence therapy in an automated manner. This research will involve 30 non-traumatic brain injury (TBI) binocularly normal (BNC) Veterans and 50 post-traumatic convergence insufficiency (PTCI) Veterans who will undergo Active and Sham therapy (equally divided groups) to determine the effectiveness of VERVE vergence therapy.

Traumatic Cerebral Vascular Injury (TCVI) is a common consequence of traumatic brain injury (TBI), including mild TBI (mTBI). TCVI is associated with poor recovery after TBI in animal models. TCVI can be measured non-invasively in humans, and therapies targeting TCVI are attractive candidates to ameliorate the consequences of TBI. Sildenafil potentiates nitric oxide (NO) dependent vasodilatation and is approved by the Food and Drug Administration (FDA) for the treatment of erectile dysfunction and primary pulmonary hypertension. In pre-clinical models of stroke, sildenafil improves cerebral blood flow (CBF), promotes, angiogenesis, neurogenesis and improves recovery. In an initial Phase 2a trial (NCT01762475) of sildenafil in patients with chronic moderate to severe TBI, the investigators found that low dose sildenafil (25 mg BID) therapy is safe and well tolerated, that a single dose of sildenafil 50 mg potentiates CVR in areas of the brain with dysfunctional endothelium, and that CVR is a reliable diagnostic marker of TCVI and has potential as a pharmacodynamic and predictive biomarker. In this proposal, the investigators will conduct a randomized clinical trial to determine the optimal PDE5 inhibitor dose to improve or normalize microvascular function (as measured by the change in CVR measurements before and after a single dose of sildenafil, or ΔCVR) using a range of sildenafil citrate doses: 20, 40, 80 mg) in chronic TBI patients. The investigators will also test the safety and tolerability of the same dose ranges of chronic (4-week) thrice daily sildenafil or placebo administration in chronic TBI patients and explore its effects on chronic symptoms and clinical outcomes.

The purpose of the study is to test whether low level electric stimulation, called transcranial Direct Current Stimulation (tDCS), on the part of the brain (i.e., presupplementary motor area) thought to aid in memory will improve verbal retrieval in military veteran participants with histories of traumatic brain injuries. The primary outcome measures are neuropsychological assessments of verbal retrieval, and the secondary measures are neuropsychological assessments of other cognitive abilities and electroencephalography (EEG) measures. Additionally, the study will examine the degree to which baseline assessments of cognition and concussion history predict responses to treatment over time, both on assessments administered within the intervention period and at follow-up.

The goal of this clinical trial is to compare pregnenolone and placebo (a placebo is a look-alike substance that contains no active drug) in Operation Enduring Freedom/Operation Iraqi Freedom/Operation New Dawn (OEF/OIF/OND)-Era Veterans with a history of chronic Traumatic Brain Injury (TBI). The main questions it aims to answer are: * Does pregnenolone improve psychological health, overall physical function, cognition, symptoms of PTSD, and pain more than placebo over the 8-week study period, and what is the most effective dose of the drug that is safe and well-tolerated? * What are the biological effects of pregnenolone, and how do pregnenolone and other molecules change over the course of treatment? (and do pregnenolone and other molecules predict clinical improvement?) Participants who are eligible and consent to participate in the study will: * be randomized in a 1:1 ratio to take pregnenolone or placebo * be given pregnenolone or placebo to take each day at home * will participate in 6 visits over 11 weeks for tests, exams and procedures that are for study purposes (each visit will last 1.5 - 3 hours) * be evaluated at each visit to determine if there are any bad reactions to the study drug and if study participation is still appropriate * be financially compensated for their visit time and travel cost Read Less

This study will assess the benefits of using mobile health system designed for individuals with chronic and complex health conditions (such as those with Spinal Cord Injury,Cerebral Palsy, Spina Bifida, and Traumatic Brain Injury) to improve their wellness and self-management skills compared to those who receive standard of care only.

Traumatic brain injury (TBI) accounts for approximately 2.5 million visits to emergency departments in the United States each year. After decades of research, management strategies for severe TBI (sTBI) patients are still evolving. Optimizing intracranial pressure (ICP) and cerebral perfusion pressure (CPP) are paramount in the management of these patients and placement of these monitors is the current standard-of-care. However, monitoring brain oxygenation (PbtO2) with invasive intraparenchymal monitors is currently under investigation in the management of severe TBI and placement of these monitors is gaining widespread use. This has opened the door for the use of tiered therapy to optimize ICP and PbtO2 simultaneously. Current evidence indicates that correction of ICP, CPP and PbtO2 in sTBI requires optimized analgesia and sedation. Ketamine is one of the few drugs available that has both sedative and analgesic properties and does not commonly compromise respiratory drive like opioids and sedative-hypnotics. However, traditionally, ketamine has been viewed as contraindicated in the setting of TBI due to concerns for elevation in ICP. Yet, new data has cast this long-held assumption into significant doubt. Hence the present pilot study will characterize the neurophysiological response to a single dose of ketamine in critically-ill TBI patient with ICP and PbtO2 monitoring. Read Less

The purpose of this research study is to test whether a portable goggle system (I-PAS) is good at diagnosing mild traumatic brain injury (mTBI) in a community setting. The goal is to determine whether the IPAS goggle system can be used reliably in an urgent care or emergency department setting. Read Less

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. Read Less

This randomized waitlist control trial will evaluate the effects of a psychoeducational intervention called Resources for Enhancing All Caregivers' Health - Traumatic Brain Injury (REACH TBI) to decrease caregiver strain (primary outcome) and improve caregiver self-efficacy, anxiety, depression, and health care frustrations (secondary outcomes). This study will modify and adapt an award-winning caregiver intervention, Resources for Enhancing All Caregivers Health in the Department of Veterans Affairs (REACH VA), to support the needs of Caregivers of Veterans and Service Members with TBI.
