Filter by:The purpose of this study is to determine whether transcranial magnetic stimulation (TMS) is effective in the treatment of suicidal thinking in individuals with a depressive episode and either posttraumatic stress disorder (PTSD), history of mild traumatic brain injury (TBI), or both conditions.
Traumatic bain injury(TBI) remains a hidden epidemic involving individuals affected predominantly at a young age who in the most severe cases remain with permanent physical,psychological and cognitive deficits.This study will investigate the therapeutic effects of intranasal Nerve Growth Factor(NGF) in TBI.
The purpose of this study was to address 3 short term objectives; (1) Determine the effects of physiologic testosterone (T) therapy on neurological function and functional independence following traumatic brain injury (TBI) in hypogonadal men during inpatient rehabilitation; (2) Document the natural history of neuroendocrine dysfunction and recovery in men during inpatient rehabilitation after TBI; (3) Obtain data to validate the NIH toolbox, a novel assessment of neurological function for use in the TBI population; and 2 long-term objectives: (1) Utilize study findings to design a multicenter trial to further assess the impact of T therapy in hypogonadal men following TBI and (2) Impact TBI practice management with new information about neuroendocrine dysfunction after TBI and hormone treatments to improve outcomes.
Aim of the study is to investigate the impact of two different fractions of inspired oxygen (FiO2) on outcome in patients with severe traumatic brain injury (TBI).
This project aims to study the prognostic ability of various MRI imaging markers in the evaluation of TBI patients. Cognitive, social, and occupational recovery will be measured at each time point, and compared to MRI findings. Healthy volunteers will serve as a comparison to the TBI patients. It is hypothesized that novel MRI markers of metabolism, hemodynamics, functional connectivity, and tissue microstructure will be related to the clinical status of the patient, as well as their social and occupational outcomes.
Background: - Previous research has shown that certain parts of the brain are involved in voluntarily stopping an ongoing motor response (movement); however, it is not known whether this same network is also involved in suppressing an urge to act. Traumatic brain injury (TBI) can significantly impair the brain's ability to voluntarily stop or inhibit certain actions. Using brain imaging (functional magnetic resonance imaging, or fMRI) and brain stimulation (transcranial magnetic stimulation, or TMS) to investigate how people perform activities that involve moving and suppressing movements, researchers hope to better understand how these brain areas might be affected in people who have had TBI. Objectives: - To determine the parts of the brain involved in suppressing an urge to act. - To determine the extent to which traumatic brain injury affecting certain parts of the brain is involved in problems with suppressing an urge to move and stopping movement. Eligibility: - Individuals 18 to 40 years of age who have had mild or moderate TBI, or are healthy volunteers. Design: - This research study includes a screening visit and two study visits, each of which will last at least 2 hours. - Participants will be screened with a physical examination and medical history. Women who can become pregnant will have a urine pregnancy test before being allowed to participate in the study. - At the first study visit, participants will complete one of the following experiment tests in an MRI scanner. - Experiment 1: Participants will be shown arrows or images on a computer screen, and will press a button or not press a button depending on the image shown. Participants will practice the experiment tasks before performing them during MRI scans. - Experiment 2: Participants will be shown arrows or images on a computer screen, and will press a button or not press a button depending on the image shown. Participants will also have TMS while at rest, and will perform the experiment tasks during the MRI scan. - At the second study visit, participants will have an fMRI scan where they will be asked to do simple response tasks with a computer outside the MRI scanner.

Background: - Traumatic brain injury may have a range of effects, from severe and permanent disability to more subtle functional and cognitive deficits that often go undetected during initial treatment. To improve treatments and therapies and to provide a uniform quality of care, more research is needed into different treatments for traumatic brain injury. - Exercise has been shown to improve movement and balance in people with strokes, cerebral palsy, and other conditions that affect the brain, and can improve symptoms of memory problems or depression. Bright light therapy has also been shown to improve mood in people with depression. Researchers are interested in studying problems with movement, balance, thinking, and mood in people with traumatic brain injury. By comparing the effects of exercise and bright light exposure on brain function, new treatments may be developed for acute traumatic brain injury. Objectives: - To compare the effects of exercise and bright light therapy on the brain function of individuals with traumatic brain injury. Eligibility: - Individuals between 18 and 44 years of age who either have been diagnosed with traumatic brain injury or are healthy volunteers. Design: - Individuals with traumatic brain injury will have four outpatient evaluation visits at the clinical center, a 3-month home exercise program, and a 3-month bright light exposure program at home. Healthy volunteers will have one evaluation visit at the clinical center. - At the first study visit, all participants will have a full physical examination and medical history. Individuals with traumatic brain injury will also have an eye exam to determine if it is safe for them to receive light therapy. - All participants will have the following initial tests: - Tests of walking and movement, including monitoring by a physical therapist; tests to record joint movement and evaluate muscle function; tests that combine movement, thinking, and speaking; and balance and reaction time tests. - Magnetic resonance imaging scans - Tests of thinking and mood, including questionnaires, computerized tests, and simple action tests. - Participants with traumatic brain injury will have separate 3-month sessions of exercise and bright light therapy, with additional evaluation visits between each 3-month session and at the end of the study. Between the 3-month sessions, participants will have 1 month with no intervention. - Exercise sessions will involve regular workouts on an elliptical machine for 30 minutes for 5 days a week, and bright light therapy sessions will involve sitting in front of a light box for 30 minutes for 5 days a week. Participants will keep a journal to monitor the effects of the therapy.
The aim of this research is to determine if the biological fluids (blood/saliva) from chronic brain-injured patients (both blast and non-penetrating TBI) contain reproducible protein markers. To accomplish this two populations of chronic TBI patients who are receiving treatment at The Institute for Research and Rehabilitation (TIRR): blast injury victims and non-penetrating TBI will be studied. Using multiple proteomic approaches including mass spectrometry, multiplex ELISAs, and antibody microarrays, as well as RNA profiling, the investigators aim to identify biomarkers in the blood/saliva of patients suffering from chronic TBI and to determine the similarities/differences between the blast and non-penetrating injury groups. Identification of these biochemical changes will give insight into the long-lasting changes associated with head injury, and may identify new targets for treating the associated pathologies.
The specific aims of the proposed study are to 1) evaluate the efficacy of FANCI for improving functional status following treatment using the FIM, 2) examine the impact of FANCI on broader outcome measures of general emotional and behavioral functioning and productive activity in the community as measured post-treatment and at 6-month follow-up, 3) examine contributions of participant injury severity and cognitive status at time of treatment to treatment outcome and treatment response, 4) examine contributions of treatment variables of session topic and mastery, caregiver presence, and concurrent therapies on treatment outcome and treatment response for inpatients with TBI. Primary outcome measure is the (FIM). We will secondarily compare scores on the Disability Rating Scale (DRS), Glasgow Outcome Scale-Extended (GOSE), Rehabilitation Intensity of Therapy Scale (RITS), and Frontal Systems Behavior Scale (FRsBe). Our design is a parallel groups, single-blind, randomized, controlled trial. We will enroll 150 (75 treatment, 75 control) participants. Inclusion Criteria: Mod to Sev TBI based on time to commands, English speaker, Length of stay ≥ 5 days in acute BI rehabilitation Unit, 18 years of age or older, ≥ 79 on GOAT.
Objective: To evaluate real acupuncture, as compare to sham acupuncture, in improving persistent sleep difficulties in veterans with mild traumatic brain injury (mTBI) Design: Randomized, blinded, sham-controlled clinical trial Setting: Outpatient clinic at a major VA medical center in Southeast USA Participants: Sixty veterans aged 24-55 (mean 40) with history of mTBI at least 3-month and beyond, suffering from sleep difficulties refractory to regular care and sleep education, as indicated by a global Pittsburgh Sleep Quality Index (PSQI) score of 14.25 + 3.23 pre-intervention (baseline). They were randomized into 2 groups, real acupuncture versus sham acupuncture, and stratified by Post-traumatic stress disorder (PTSD) diagnosed by PTSD CheckList - Military Version (PCL-M). Intervention: Real or sham acupuncture with both standardized and individualized acupoints selection. All subjects were informed that the treatments, if effective, may improve symptoms such as pain, anxiety or depression other than sleep; real acupuncture may not be effective in some individuals, and sham acupuncture may as well be effective by mind-body interactions. Outcome Measures: Primary outcome measure was global PSQI score change after intervention as compared to baseline. Secondary outcome measure was wrist-actigraphy sleep latency, sleep efficiency, wake after sleep onset (WASO), and sleep duration. PTSD was analyzed as a co-variant.
