Filter by:Background: A traumatic brain injury (TBI) could mean a person is at high risk for other long-lasting problems. These problems could include post-traumatic stress disorder (PTSD), depression, and post-concussive syndrome (PCS). For example, about 700,000 Americans each year who have a TBI later go on to have PTSD also. Depression and PCS are also common in people who had a TBI. Some people will have these problems later. These problems can seriously interfere with a person s life. Some people will not have these problems at all. There are many reasons for this difference. Researchers think the main reason is that people have different genetic and environmental influences. Right now, we only have few kinds of treatments to prevent or treat these problems after a TBI. The few treatments we have often do not work well. It is important to understand what factors make a person at high risk for these problems after a TBI. This could allow researchers and doctors to help address these problems early. Addressing these problems earlier may help a person have better health in the long run. Objectives: - To study the biological changes that happen after mild to moderate TBI which could be linked to the onset of PTSD, depression, and post-concussive syndrome - To study brain mechanisms that could explain risks for getting a psychiatric disorder after mild to moderate TBI. This will be done using a test called functional MRI (fMRI). This test takes images of the brain while a person is doing a simple task. Eligibility: - Men and women who are 18 to 65 years old. - Had a mild to moderate TBI (including concussion) in the last month. Design: - 5 outpatient visits to the NIH Clinical Center over one year. - The first visit is a screening visit to see if you can join the study. This visit must happen within 30 days of the TBI. The visit includes lab work (blood and urine), a history and physical exam done by a physician or nurse practitioner, and a psychiatric interview with a behavioral health nurse. - Visits 2, 3, 4 and 5 happen at one, three, six and twelve months post-injury. At these visits participants may have some or all of the following tests: blood and saliva collection, urine collection, questionnaires and interviews to assess symptoms, a test to see your response to stress (called hydrocortisone challenge), and fMRI brain imaging. - This study does not provide treatment. - This study is not a substitute for seeing a primary care provider. - This study should not replace any therapies you may be taking.
In this study researchers will apply transcranial direct current stimulation (tDCS) for 5 consecutive days in chronic patients in minimally conscious state (MCS). 2 sessions of 5 days of stimulation will be realized, one anodal and one sham. After each stimulation, behavioral improvement will be assessed with the Coma Recovery Scale Revised (CRS-R). A final assessment will be done one week after the end of the sessions to assess the long term effect of the tDCS.
The purpose of this study is to determine 1. if it is practical to treat moderately to severely brain injured patients who have problems with their balance and mobility in a group "boot camp" (3 days a week, 6 hours/day for 4 weeks) exercise class. 2. If they show improvements compared to 4 weeks of not receiving this treatment 3. If electronic daily monitoring of their center of foot pressure during a standardized balance task will allow us to see small changes in ability. A baseline assessment of all outcome measures will be performed. This will be repeated 4 weeks later. The intervention will be delivered (4 weeks) and a follow up assessment of all outcome measures will be performed one week later. A follow up of the Primary outcome measure, the PART-O participation questionnaire will be done 12 weeks later. Participants will attend group therapy consisting of a variety of exercises designed specifically to target balance and mobility deficits and based on the concept that through Repetitive Functional Task Practice (RFTP), recovery of function can occur as the result of neural adaptation. Exercises will be both individualized (delivered in a circuit) and group activities. Supervision and guidance will be provided by a registered Physical Therapist and a Rehabilitation Assistant. During the intervention, the amount and type of RFTP, any adverse events, and any need for extra staff will be recorded on a daily basis. As well, a standardized individualized task will be performed with center of foot pressure recording on a daily basis. Analysis: changes in outcome measures immediately after the non-intervention compared to the after the intervention period will be statistically determined to estimate efficacy of this treatment model. Descriptive measures of RFTP time/day, staffing levels/day and adverse events will be used to support feasibility and safety of this model.
Traumatic brain injury (TBI) is the most common cause of death and disability in young adults. Patients can experience significant problems with concentration, attention, and memory (so called 'cognitive impairments') following TBI. These cognitive impairments can drastically impact on a patient's well-being, and can lead to significant economic and social consequences. Roughly a quarter of TBI patients improve but an equal number deteriorate over time. The investigators know little about why patients vary so much in how they recover. Crucially, the investigators have no treatments to improve brain functioning or recovery after TBI. Trials investigating ways of protecting the brain just after injury have been disappointing. An alternative strategy, however, is to improve the function of brain regions that remain intact, but that function inefficiently after TBI. The investigators know that dopamine (a chemical in the brain) is known to influence many brain functions and the investigators know that pathways in the brain that use dopamine are affected by TBI. In humans, drugs that increase dopamine in the brain, such as methylphenidate, are sometimes used to enhance cognitive function after TBI, but the response to treatment can be highly variable between patients. Therefore, what is needed in the clinic is a way to target the use of these drugs to patients who are likely to respond. In a single centre study, the investigators will use SPECT (Single Photon Emission Tomography) imaging to measure dopamine levels in the brain. MRI (Magnetic Resonance Imaging) scans will assess brain structure and function. The investigators will test whether treatment with methylphenidate improves cognitive functions in TBI patients who have ongoing cognitive problems, whether the mechanism involves a normalisation of brain functioning and whether brain dopamine levels can predict the magnitude of any improvement in symptoms.
In the exploratory multi-center Phase 2 a study safety, tolerability, pharmacodynamics and pharmacokinetics of the Nitric Oxide Synthase inhibitor VAS203 is assessed in patients with moderate and severe traumatic brain injury. Traumatic brain injury patients (32 males) receive 15, 20 and 30 mg/kg VAS203, respectively, by continuous infusion in three cohorts (Cohort 1 open; Cohorts 2 and 3 double blind, randomised placebo-controlled). End of Study for all patients will be Day 14; adverse events and concomitant medications will be documented throughout the study. Objectives are to assess safety and tolerability of VAS203, to evaluate concentrations of metabolites of VAS203 in plasma and microdialysate and to assess pharmacodynamic effects of VAS203 on surrogate parameters. Safety parameter will include vital signs (blood pressure heart rate, respiration rate, oxygen saturation and blood gases), fluid balance, ECG, laboratory examinations (clinical chemistry, liver function, haematology/coagulation, urinalysis, renal parameters) and adverse events. Concentration of VAS203 will be determined in plasma and microdialysate. Pharmacodynamic parameters will include intracranial pressure (ICP), biochemical parameters in microdialysate (nitrite/nitrate, arginine, citrulline, pyruvate, lactate, glucose), Partial Oxygen Pressure in brain parenchyma and Therapy Intensity Level (TIL).
CREACTIVE is a large-scale observational cohort study concerning Traumatic Brain Injury (TBI) care in the ICU setting
Treatment for veterans who have had a traumatic brain injury (TBI) and who are suffering from post traumatic stress syndrome (PTSD) is varied with varied outcomes. Investigators will study PTSD treatment in military Veterans who have suffered traumatic brain injuries. Investigators will use 1 independent specialty treatment centers that utilize a specific novel methodology of PTSD treatments and study the clinical outcomes of veterans who have suffered a TBI with associated post-concussive symptoms and other comorbidities such as PTSD. Investigators hypothesize that the treatment of PTSD will have a significant outcome with neurological physical and vestibular rehabilitation when compared to psychological or psychiatric therapy. This study will use gold standard measurement scales and compare changes in the scales after treatment to evaluate the treatments.
Morbidity and mortality of ICU patients is increased by the development of a "immunosuppression" systemic (IS). This IS develops in the early hours of hospitalization and is responsible for severe infections, including viral reactivations (Cytomegalovirus or Herpes Simplex Virus). Viral reactivation was associated with increased morbidity and mortality in intensive care units. In clinical practice, they are searched at the onset of organ failure or unexplained fever. The investigators wish to conduct this research in the stroke patients to assess the predictive power of these viral reactivations on the duration of mechanical ventilation.
This project was designed to determine brain imaging patterns using 2-(1-{6-[(2-fluorine 18-labeled fluoroethyl)methylamino]-2-naphthyl}ethylidene)malononitrile ([F-18]FDDNP) with positron emission tomography (PET) in participants with suspected Chronic Traumatic Encephalopathy (CTE), a progressive degenerative disease of the brain found in people with a history of repetitive traumatic brain injuries (TBIs), characterized by personality, behavioral, and mood disturbances, cognitive impairment, and sometimes motor symptoms. Currently, CTE can only be definitely diagnosed from neuropathological examination of the brain after autopsy. Developing tools to assist in the detection of this condition in living individuals at risk would facilitate research focusing on discovering potential prevention and treatment strategies.
The purpose of this research study is to investigate different types of task training to determine if training improves thinking processes following traumatic brain injury.
