Filter by:We will explore the use of Huperzine A in patients who have sustained a moderate to severe Traumatic Brain Injury. We aim to determine whether Huperzine A, as compared with placebo, would have an effect on memory function after TBI. Additionally, we aim to determine whether use of Huperzine A in these patients can change brain activity (as indexed by EEG and Transcranial Magnetic Stimulation - TMS), and reduce prevalence/frequency of post-traumatic seizures. We also aim to evaluate the safety of Huperzine A in this population as compared with placebo.
The purpose of this trial is to investigate safety and efficacy of Cerebrolysin as add-on therapy to standard care in patients with acute traumatic brain injury (TBI). The study duration for each patient is 180 days.
The purpose of this study is to develop and validate eye-tracking measures that can be used to evaluate neurocognitive dysfunction among individuals with traumatic brain injury (TBI).
The purpose of this study is to examine differences in post-concussive (PC) symptom endorsement among four groups of Operation Enduring Freedom (OEF)/Operation Iraqi Freedom (OIF) Veterans: those with a history of target, service-related, mild traumatic brain injury (mTBI) and co-occurring posttraumatic stress disorder (PTSD) (Group 1); those with a history of target, service-related, mTBI only (Group 2); those with PTSD only (Group 3); and those with no history of target, service-related, mTBI or PTSD (Group 4) by examining scores on the Neurobehavioral Symptom Inventory (NSI). Support for this study is provided by previous research highlighting the complex relationship between mTBI, PTSD and subsequent PC symptom endorsement (Brenner et al. 2010; Terrio et al, 2009). HYPOTHESES ARE AS FOLLOWS: 1. Individuals with a history of target, service-related, mTBI only (Group 2) and individuals with PTSD only (Group 3) each will report significantly more PC symptoms, as measured by NSI total scores, when compared to those with no history of service-related mTBI or PTSD (Group 4). 2. Individuals with co-occurring target, service-related, mTBI history and PTSD (Group 1) will report significantly more PC symptoms, as measured by total NSI scores, than either those with target, service-related, mTBI only (Group 2) or those with PTSD only (Group 3).
This study will evaluate the feasibility of using fully implanted microstimulators to rehabilitate arm function in patients who have suffered a traumatic brain injury.
Background: - A person who has a traumatic brain injury (TBI) -- also called concussion -- can have serious and long-lasting effects. Doctors who treat TBI need more information about how the brain changes over time in people with TBI and how well a person recovers from it. To make existing TBI treatments more effective and develop new ones, researchers want to look more closely at how TBI affects people both physically and psychologically. Objectives: - To collect medical information from people with recent traumatic brain injury and compare this information to that of healthy volunteers and of persons who have had injuries to other parts of their bodies besides their heads (such as broken bones, orthopedic injuries, after surgery). Eligibility: 3 groups of people between the ages of 18 and 70 years will be asked to take part. - Persons who have had a traumatic brain injury (or concussion ) within the past 30 days, OR - Persons who are healthy and have never had a traumatic brain injury, OR - Persons who have had an injury within the past 30 days to a part of their body other than the head (such as a broken bone, orthopedic injury, surgery) Design: - This study requires two outpatient visits each lasting 1 1/2 days. The 2 visits will be about 30 days apart. Persons with TBI and non-TBI injuries must have their first visit within 30 days of their injury. - Screening: Participants will be screened with a medical history, physical examination, blood tests and electrocradiogram (ECG a routine heart test). - The research will involve: 1. Giving blood samples (no more than 75 ml each visit). 2. Having tests of memory, attention, concentration, and thinking (neuropsychological testing). 3. Having imaging studies of the head including magnetic resonance imaging (MRI) and positron emission tomography (PET) scans. - Persons with TBI will have the same tests at Visit 1 and 2. Healthy controls and persons with non-TBI injuries will have the same tests at Visit 1 as listed above. But, at Visit 2, they will not have brain MRIs or PETs. - No treatments will be provided as part of this research protocol.
Background: - Many people who have had a traumatic brain injury have difficulty walking. Training on a treadmill is often used to help people with walking difficulties. Supporting a person s body weight with a harness while using the treadmill can help improve walking skills in people with brain injury. Varying the rate at which people walk on the treadmill may also help more than walking at a constant rate. Treadmill training with body weight support or walking at different speeds may improve walking skills in people who have had a traumatic brain injury. More research is needed to see if one method is better than the other. Objectives: - To compare the effects of two types of treadmill training in people who have had a traumatic brain injury. Eligibility: - People at least 18 years of age who have had a mild or moderate traumatic brain injury at least 6 months ago and have mild or moderate walking difficulty. Design: - Participants will be screened with a medical history and physical exam. They will also take a basic walking test (not on a treadmill). - Participants will be divided into two groups. The first group will have treadmill training at a constant speed. The second group will have treadmill training at different speeds. All participants will wear a support harness while walking on the treadmill. - At the first training visit, participants will have a gait assessment with different tests of walking. Then they will have a treadmill walking session. - After the first visit, participants will return twice a week for 6 weeks for treadmill training sessions (visits 3 through 12). They will also have grip strength and walking tests. - At the end of 6 weeks, participants will have a final treadmill training session, and will have a gait assessment exactly like the one in the first training visit. - At 6 months after the final session, participants will have a followup visit with a final gait assessment.
This study will evaluate the efficacy of methylphenidate and galantamine in the treatment of persistent cognitive symptoms associated with posttraumatic stress disorder (PTSD) and/or traumatic brain injury (TBI).
The investigators hypothesize that hypothermia (body cooling) and additional magnesium sulfate will improve the outcome of severe Traumatic Brain Injury (TBI) patients. This is a study to compare the outcomes of patients with severe traumatic brain injury who have been allocated to one of the following three groups: Group 1 - Conventional therapy following traumatic brain injury Group 2 - Subjects will have their core body temperature lowered to 34C Group 3 - Subjects will have their core body temperature lowered to 34C and will receive a supplemental intravenous infusion of magnesium sulfate.
The primary objective of the study is to compare the efficacy of duloxetine 60 mg by mouth daily with placebo in the prevention of depression associated with mild/moderate traumatic brain injury and to enhance cognitive function.
