Filter by:Traumatic brain injury (TBI) is an important public health problem with an estimated 1.7 million new cases in the United States each year. Although the vast majority of these victims sustain mild TBI, many still develop headache, difficulty concentrating, and decreased memory with potential for serious long-term consequences. In particular, mild TBI is an important consequence of combat-related injuries sustained by military personnel and sports-related injuries in young adults. Unfortunately, treatment of mild TBI is usually limited to oral analgesics for headache pain such as acetaminophen (Tylenol) or ibuprofen (Motrin or Advil). Since there are no previous randomized trials of these medications for mild TBI, their comparative effectiveness is not known. Increasing animal based evidence suggests that mild TBI is related to brain cell injury caused by overexpression of a cellular enzyme (COX-2) that causes neuroinflammation. Fortunately, inhibition of COX-2 is easily achieved using ibuprofen. We hypothesize that head injured patients treated with ibuprofen will have a lower incidence of mild TBI symptoms than patients treated with acetaminophen. We will conduct a randomized clinical trial to measure the comparative effects of ibuprofen versus acetaminophen on the incidence of specific symptoms of mild TBI in emergency department patients with head injury.
The purpose of this study is to evaluate improvement in balance after receiving physical therapy when augmented by CN-NINM than when augmented by a placebo (sham CN-NINM).
The purpose of this study is to determine the feasibility of combining PoNS therapy with standard vestibular and balance therapy with the proposed double-blind design; evaluate preliminary indications of efficacy. This study is also evaluating recruitment rate, completion rate, device usability, and outcome measures feasibility. - Goal for recruitment: 100% of 30 subjects meeting all inclusion criteria can be recruited over the 36 week pilot recruitment phase. - Completion and compliance: 90% of subjects will complete the study, 90% of sessions within each subject will be completed, and for completing subjects, 100% of measures will be completed. - Useability: all therapists and subjects must rate useability as good or better. - Success of blind: subject accuracy at guessing group membership must be at or near 50%.
This is a research study to learn if a computer-based intervention that provides direct attention and metacognitive strategy development can improve attention, memory, and executive control in adolescents with moderate-to-severe TBI who are experiencing attention difficulties post injury.
The purpose of this study is to explore the effectiveness of adding lithium carbonate (lithium) to treatment for combat-related post traumatic stress disorder in combat veterans. The goal of this study is to establish that lithium is a practical and tolerable treatment option for veterans with combat posttraumatic stress disorder.
This investigation will explore the impact of 8 weeks of citicoline treatment on cognitive function, clinical state and substance use in 40 individuals with mild traumatic brain injury (mTBI).
Background: - Some people who have a traumatic brain injury (TBI) recover completely. Others, however, develop post-traumatic stress disorder (PTSD), with anxiety and depression. Research suggests that levels of a brain chemical called GABA may differ in people with PTSD compared to those without PTSD. Researchers want to see if TBI can affect GABA in the brain and help develop PTSD. To look at the brain, researchers will use imaging studies with the chemical 11C-Flumazenil, which will help the scan show GABA levels in the brain. Objectives: - To study the relationship between PTSD and TBI. Eligibility: The subjects will be recruited from the Walter Reed National Military Medical Center (WRNMMC). - Individuals between 18 and 50 years of age who have PTSD and/or had a mild TBI. - Healthy individuals between 18 and 50 years of age who have no history TBI and no history of PTSD. Design: - Participants will be screened with a physical exam and medical history. Urine and breath samples will also be collected. - Participants will have two imaging studies, on the same day if possible. The first will be a magnetic resonance imaging scan to look at the brain. The second will be a positron emission tomography scan with the study chemical to look at GABA pathways in the brain....
The purpose of this study will be to assess the attentional ability of patients with mild to moderate traumatic brain injury (TBI) using the functional Magnetic Resonance Imaging (fMRI) technique. Methodology for specific aim 1: sagittal pilot scan, 3-D anatomical MRI, Whole brain echo-planar imaging (EPI), and functional MRI techniques with traumatic brain injured subjects doing a Continuous Performance Test (CPT) attention task and compare the pattern of activation with those of normal controls to see if there is a failure to activate frontal lobes in the traumatic brain injured subjects.
Head impacts in sports can lead to brain injury even when the participant is wearing a helmet. The forces that contribute to brain injury from sports-related head impacts are not well understood. This study will test a new device to measure the speed of head impacts among football players.
