Active clinical trials for "Brain Injuries, Traumatic"

Patients who completed the 12-week double blind protocol may enter this 26-week, open-label extension. This extension will give patients who complete the study an opportunity to receive treatment with open-label rivastigmine 3-12 mg/day and further evaluation for the cognitive deficits related to traumatic brain injury. This extension will enable further evaluation of patients, as well as analyses to be conducted examining response to treatments in the original drug and placebo groups.

This study is a prospective single-centre randomized trial to compare the effect of tranexamic acid versus placebo in the pre-hospital management of patients with moderate and severe traumatic brain injury.

The objective of this proposal is to evaluate the effectiveness of rehabilitation for visual attention deficits in U.S. military service members across three programs: Visual Attention and Working Memory Programs (UCR Games), Speech Pathologist-Directed Treatment, and General Cognitive Rehabilitation Games (Lumosity). In addition to the above prospective component, this study also has a retrospective component in which archival data collected from routine clinical care will be examined for analysis. The investigators hope to gain a better understanding of the unique and cumulative influence different cognitive rehabilitation programs have on improving attention complaints in mTBI.

The overall objective of this project is to determine the efficacy and tolerability of TMS for mild Traumatic Brain Injury (mTBI) with PTSD symptoms and correlate treatment response with anatomical and biological factors unique to each service member (SM). Exploratory work will be done to look at the neuronal and biological changes that may occur over the course of TMS treatment.

Many survivors of acquired brain injury (ABI) suffer from decreased balance and increased risks of falls. Previous studies indicate that balance training improves balance, reduces falls, and increases walking speed and balance confidence. The purpose of this study is to determine if a multidimensional balance training based on the FallProof(TM) approach achieves better improvements in balance and walking performance than the current practice . Participants will be assigned to: 1)a task-oriented circuit training balance class (current practice), or 2) balance training class based on the FallProof(TM) approach. Standardized tests will determine if participating in balance training helps improve balance, walking speed and balance confidence.

This research study evaluates the effectiveness of a low-cost Virtual Reality-based (VR) training system in providing a customized balance treatment in a skilled clinical setting. Participants will be assigned to one of three treatment groups.

The main objective of this study is to evaluate the effects of tRNS while undergoing computerized cognitive rehabilitation therapy to conclude if this combination of therapies would be effective for the cognitive rehabilitation of patients with acquired brain damage, such as traumatic brain injury. We want to study the therapeutic potential of tRNS to enhance the therapeutic outcome of cognitive training, studying its global effect over the rehabilitation of attention, memory and executive functions, compared to sham tRNS.

Traumatic brain injury (TBI) is a severely disabling injury which affects 150-200 people per million annually. Increasing evidence suggests that TBI may be a major risk of dementia, Alzheimer's disease (AD) in particular. Postmortem evidence has shown that beta-amyloid (Aβ) deposits, one of the most validated pathological biomarkers of AD, are present in the brains of severe TBI patients. Although the underlying mechanisms remain unclear, the axonal injury may play a role. Imaging investigations have revealed Aβ density maps of TBI patients overlapped with those of AD patients, and increased Aβdensity not only associated with prolonged TBI duration but also associated with decreased white matter integrity. Hence, the increasing accumulation in Aβ due to TBI may contribute to the initiation of the pathological alterations seen in AD. Treatment of TBI may not only be of benefit for the injury itself but also act to block the pathological changes in AD. As a part of the clinical arm of the project, in this subproject investigators will conduct a single-blind, block-randomized clinical trial to investigate the efficacy of acupuncture in TBI. More specifically, investigators hypothesize that acupuncture intervention will elicit neuroprotective processes and thereby reduce axonal damage in TBI, manifested as (1) decreased plasma levels of Aβ peptide, tau, and glial fibrillary acidic protein (GFAP) and (2) increased white matter integrity after acupuncture. Ninety-six participants will be randomly allocated to the acupuncture intervention (verum acupuncture) or control group (sham acupuncture) in a 1:1 ratio. All participants will receive 20 minutes of acupuncture treatment twice a week for 2 weeks. A set of commonly used acupoints for TBI treatment will be manually stimulated every 10 minutes. The multi-modality magnetic resonance imaging (T1, T2, and diffusion tensor imaging) and blood sample will be taken before and after the acupuncture session to measure the white matter integrity in brain and plasma levels of Aβ peptide, tau, and GFAP, respectively. After integrate these data with other subprojects, we can provide synergic and integrative mechanisms of the effects of acupuncture on the risk of AD after TBI.

This study will examine the behavioural and neurophysiological efficacy and feasibility of an online spatial navigation intervention for improving memory and brain health in individuals who have sustained moderate-severe traumatic brain injury.

In the present study the investigators aim to analyze the performance in a battery of social cognition tests of subjects with traumatic brain injury. On the other hand, the effectiveness of a computerized rehabilitation program designed to improve these deficits will be tested, as well as the relationship between social cognition and executive functioning.
