Effects of LEDs on Memory in TBI Patients
Traumatic Brain InjuryThe purpose of the study is to investigate whether transcranial, high-intensity LED placed on the scalp can improve working memory in people who have sustained a concussion with lingering effects or a mild brain injury.

Effectiveness of Amantadine Hydrochloride for Treatment of Severe Traumatic Brain Injury (TBI)
Traumatic Brain InjuryThis is a controlled trial of amantadine to improve level of function following severe traumatic brain injury. The purpose of this study is: To determine whether amantadine hydrochloride, given in a dose of 200-400 mg, improves functional recovery from the vegetative and minimally conscious states To determine whether amantadine-related gains in function persist following drug discontinuation To determine the safety profile of amantadine in patients with disorders of consciousness

Effects of Rapid-Resisted Exercise and Bright Light Therapy on Ambulatory Adults With Traumatic...
AdultTraumatic Brain Injury1 moreBackground: 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.

Neural Bases of Cognitive Rehabilitation for Brain Injury
Brain InjurySome of the most common and disabling consequences of brain injury are deficits in cognition, such as difficulty with sustained attention, memory, organization, and goal management. The long-term goal of this research program is to develop and test novel neuroscience-based cognitive interventions for improving attentional regulation and related "executive function" brain processes involved in goal-directed behavior.

Erythropoietin in Traumatic Brain Injury (EPO-TBI)
Traumatic Brain InjuryThis study seeks to determine if erythropoietin alpha (EPO) administered to adult critical care patients with moderate or severe traumatic brain injury improves neurological function assessed at six months after injury.

Duration of Hypothermia for Neuroprotection After Pediatric Cardiac Arrest
Cardiac ArrestBrain InjuryIn this study, children who survive cardiac arrest will be evaluated whether 24 or 72 hours of whole body hypothermia (cooling) during recovery is better to help prevent brain injury and improve outcome. The investigators will also test the safety of cooling patients for 24 and 72 hours. The investigators hypothesize that 72 hours of cooling will be more beneficial than 24 hours without compromising safety.

Effect of Xenon and Therapeutic Hypothermia, on the Brain and on Neurological Outcome Following...
Ischemic Brain InjuryThe main purpose of this study is to explore whether xenon is neuroprotective in humans. In addition, the purpose is to explore the underlying mechanisms for the possible synergistic neuroprotective interaction of xenon and hypothermia in patients suffering cerebral ischemia post cardiac arrest, by undertaking brain imaging to evaluate their effects on cerebral hypoxia, neuronal loss and mitochondrial dysfunction. In addition, the investigators aim to correlate these findings with neurological outcome to determine surrogate markers of favourable clinical outcome at six months.

Life Improvement Following Traumatic Brain Injury
Traumatic Brain InjuryDepressionThe purpose of this study is to test the effectiveness of a telephone-based and in-person Cognitive Behavioral Therapy (CBT) intervention for treating Major Depressive Disorder (MDD) following Traumatic Brain Injury. Participants are randomly assigned to receive one of the following: 1) Telephone-based CBT, 2) In-person CBT, or 3) Usual care (control).

Hyperbaric Oxygen Therapy in Chronic Stable Brain Injury
Brain InjurySequelae3 moreThe purpose of this study is to discover the feasibility of conducting clinical research in individuals with chronic sequelae following brain injury who are given hyperbaric oxygen. This study will also look at the outcome of individuals with a chronic stable brain injury due to trauma, anoxia (lack of oxygen to the brain), or stroke, who are given hyperbaric oxygen. Outcome measures testing cognitive (memory, etc.) and functional (balance, strength, etc.) measures will be performed before the hyperbaric sessions, immediately following them, and 6 months later. The subject will receive 60 hyperbaric sessions, 60 minutes in the chamber, to a pressure of 1.5 ATA, once daily, Monday through Friday.

Recombinant Human Growth Hormone During Rehabilitation From Traumatic Brain Injury.
Traumatic Brain InjuryGrowth Hormone (GH) deficiency, defined by insufficient GH response to a variety of stimulating compounds, is found in 20-35% of adults who suffer traumatic brain injuries (TBI) requiring inpatient rehabilitation1. However, there is no accepted gold standard for diagnosing GH deficiency in this population. Further, the major effector molecule of the somatotropic axis, Insulin-Like Growth Factor-1 (IGF-1) has recently been recognized as an important neurotrophic agent. Since most repair and regeneration after TBI occurs within the first few months after injury, absolute or relative deficiencies of GH and IGF-1 in the subacute period after TBI are potentially important factors why some patients fail to make a good functional recovery. The proposed study is a randomized, double-blind, placebo-controlled trial of rhGH, starting at 1 month post TBI, continuing for 6 months. This study has one primary hypothesis, that treatment with recombinant human Growth Hormone (rhGH) in the subacute period after TBI results in improved functional outcome 6 months after injury. As secondary hypotheses, we will investigate what is the optimal method to diagnose GH deficiency in TBI survivors and study the relationship between GH deficiency and insufficiency and functional recovery.
