Active clinical trials for "Brain Injuries"

Poor emotion recognition has been associated with poor quality of interpersonal relationships, loss of employment, behavioral problems, reduced social reintegration, social isolation and even suicide. Deficits in emotion recognition are common in traumatic brain injury (TBI) and in post-traumatic stress disorder (PTSD) but these deficits have not been well studied in Veterans with both mild TBI (mTBI) and PTSD. Currently there are no interventions for emotion recognition in Veterans with mTBI and PTSD, and interventions for severe TBI have lacked training of both facial and vocal emotion recognition. In a preliminary study of an innovative combination of facial and vocal modalities, a multimodal affect recognition training (MMART) showed promise but lacked attention training that is an essential component in recognizing emotions in our daily lives. Given the need to improve relationships and productivity in Veterans with mTBI and PTSD, a study is needed to determine the effectiveness of a MMART combined with attention training.

Current therapy of Mild traumatic brain injuries (TBI) revolves around symptomatic care, rest, and return to school/sport/work after symptoms have resolved. The standard intervention for sufferers of mild traumatic brain injury is brain rest, which aims to decrease symptom intensity and duration, prevent re-injury and second impact syndrome via cessation of physical and cognitive activity, and to gradually increase activity as tolerated. Increased brain temperature can be a secondary injury result in TBI. There are limited studies, primarily in the sports medicine literature, that show head-neck cooling can be a useful adjunct as a treatment for mild TBI. Our objective will be to evaluate concussive symptoms via the Post-Concussion Symptom Severity Score Index by conducting patient follow up interviews at different timepoints over 72 hours after an emergency department visit for the head injury where head and neck cooling was applied.

After acquired brain injury (ABI), persons can experience emotional and behavioral difficulties, that can be painful both for the person and his/her family. This clinical study aims at measuring the effectiveness of a third wave cognitive behavioral therapy called "dialectical behavior therapy" (DBT). DBT aims at teaching persons emotion regulation skills, interpersonal effectiveness skills, mindfulness and distress tolerance skills through group and individual sessions. The study's hypothesis is that DBT, in an adapted format for persons with ABI can lead to a better quality of life, emotional and behavioral regulation, and self-esteem decrease in problematic behaviors progress in life goals increase post traumatic growth and spirituality better family functioning and lesser burden for care givers experiencing more emotions and more free will 45 persons with an ABI sustained more than 18 month back, will follow a 3 phases, follow-up with care as usual for 5 months, followed by 5 months of DBT, followed by 5 months of care as usual + DBT monthly sessions. Self- and family-questionnaire will explore quality of life, emotional regulation, self-esteem, stress, anxiety, cognitive difficulties, family functioning and coping, post traumatic growth and spirituality and will be compared across the 3 phases. Results will be analyzed at a group level but also at an individual level (each patient separately) to test for decrease in unwanted behaviors and at a dyadic level (the person and his/her spouse) to test for the mutual effect of regulating emotions. Persons' memories will by analyzed at 3 time points by a linguistic analysis, and experience of free will after ABI will be analyzed by transcribed narratives of participants.

This study will evaluate the changes in respiratory mechanics following traumatic brain injury and determine the effect of inhaled nitric oxide on gas exchange.

The prevention of secondary brain injury is a primary goal in treating patients with severe traumatic brain injury (TBI). Secondary brain injury results from tissue ischemia induced by increased vascular resistance in the at-risk brain tissue due to compression by traumatic hematomas, and development of cytotoxic and vasogenic tissue edema. While traumatic hematomas may be managed surgically, cytotoxic and vasogenic edema with resulting perfusion impairment perpetuates brain ischemia and injury. Animal models suggest that remote ischemic conditioning (RIC) can reverse these effects and improve perfusion. Based on these findings it is hypothesized that RIC will exert beneficial effects on TBI in man, thereby representing a new therapeutic strategy for severe TBI. Patients presenting to our institution suffering from severe TBI will be considered for enrollment. Eligible patients will have sustained a blunt, severe TBI (defined by Glasgow Coma Scale <8) with associated intra-cranial hematoma(s) not requiring immediate surgical decompression, with admission to an intensive care unit and insertion of an intra-cranial pressure monitor. Patients will be randomized to RIC versus sham-RIC intervention cohorts. RIC interventions will be performed using an automated device on the upper extremity delivering 20 cumulative minutes of limb ischemia in a single treatment session. The planned enrollment is a cohort of 40 patients. Outcomes of this study will include multiple domains. Our primary outcome will include serial assessments of validated serum biomarkers of neuronal injury and systemic inflammation. Secondary outcomes will include descriptions of the clinical course of each patient, radiologic assessment of brain perfusion, and neurocognitive and psychological assessment post-discharge. If clinical outcomes are improved using RIC, this study would support RIC as a novel treatment for TBI. Its advantages include safety and simplicity and, requiring no specialized equipment, its ability to be used in any environment including pre-hospital settings or in austere theatres. The investigators anticipate that TBI patients treated with RIC will have improved clinical, biochemical, and neuropsychological outcomes compared to standard treatment protocols.

One of the most pressing concerns within the VA currently is the provision of interventions that address the cognitive as well as emotional problems faced by Veterans with mild TBI and comorbid conditions. When completed, these studies will inform us whether training core attentional self-regulatory control functions via personally-relevant activities will be effective in improving daily life for Veterans with mild TBI and comorbid conditions. The study design will provide a test not only of potential benefits for real life functioning, but also determine to what extent these benefits are related to actual changes in cognitive/behavioral performance and brain networks corresponding to these functions. This project will provide a foundation for future studies to investigate the neural mechanisms that support improvements of cognition and behavior in mTBI.

To examine efficacy of combined unimanual and bimanual intensive therapy in children with unilateral brain injury. A key question in hemiplegia therapy is whether the affected hand should be trained alone or in tandem with the other hand. In constraint-induced movement therapy (CIMT), a participant's less-affected upper extremity is restricted with a sling, cast, or mitt, while the participant actively uses the affected arm and hand in skill-based therapeutic activities. Bimanual therapy, in contrast, engages both hands in therapeutic movement. Since constraint and bimanual therapy target different aspects of hand use, they could have synergistic effects on hand function when given in combination.

Neurofilament Light Chain Protein (NfL) has been found by many studies as a sensitive biomarker of neuronal damage from several reasons, e.g. neurodegenerative diseases (Alzheimer's disease, Multiple Sclerosis, etc.), inflamation (HIV) or trauma. Its role as biomarker thus offers a possibility to predict and manage diseases associated with neuronal damage. Therefore our aim is to investigate the changes in level of NfL in hydrocephalus and to find its role in management of treatment in hydrocephalus.

In the current study, the investigators aim to understand the role of transcranial direct current stimulation (tDCS) in improving executive function across neuropsychiatric populations known to have deficits in this cognitive domain.

This project will examine if computerized cognitive remediation will improve working memory and attention in 25 adults with moderate to severe brain injury and compared their cognitive performance to the control group of 25 adults with moderate to severe brain injury. The control group will train on computerized tasks of social awareness. Participants in both groups will be assessed prior to training and immediately post-training and one month-post training.
