Filter by:The purpose of this study is to explore the relationship between attempted and/or completed suicide and reported experience of chronic pain among an adult veteran population. Specific aims include a) examining the experience of chronic pain between patients who have either attempted and/or completed suicide, non-suicide attempt mental health patients, and non-mental health chronic pain patients and b) determining possible differences in reported experiences of chronic pain based on mental and physical diagnoses, age, gender, ethnicity, occupation, and patient's recorded perceptions of depression and/or quality of life. As articulated in the Amendment approved on June 13, 2008, additional areas of interest include histories of neurological disease (e.g. traumatic brain injury) and/or mental health diagnoses. History of both neurologic disease and mental health diagnoses will also be identified by chart review (per approval obtained June 13, 2008). As such this study will also compare differences (e.g., mental health, neurological disease) between veterans who have history of a suicide attempt, completion, or a lifetime history of suicidality and matched control veterans without a history of suicide attempts, completions, or lifetime history of suicide. The relationship between suicidal behavior, attempted/completed suicide, and reported Post Traumatic Stress Disorder (PTSD) symptoms among an adult veteran population is also of interest. Additionally, this data set will be used to complete a validation study regarding the Self-Directed Violence Classification System (SDVCS). Specifically, relevant information in subject chart notes regarding self-directed violence (SDV) will be used to categorize thoughts and behaviors according to the SDVCS.
Background: - Many service members have reported feeling tired, a loss of motivation, mood changes, and problems working with others after they have a concussion during deployment. These problems may lead to problems with their job and relationships. This study hopes to figure out what parts of the brain may be affected in people with these problems after a concussion. Objectives: - To learn more about the problems that may occur after service members have a concussion during deployment and return home. Eligibility: - Service members or veterans between 18 and 40 years of age who have had a mild traumatic brain injury (concussion) in the past 6 months. - Companions (at least 18 years of age) of the service members will also be included in this study. Companions will have interacted with the service member at least 1 hour a week since deployment. Design: - Service members will have 1 week of tests at the National Institutes of Health Clinical Center. Companions will have 2 days of tests at the Center. - Each day, service members will have 4 or 8 hours of tests. Tests will include a medical history and physical exam, neuropsychological tests and imaging studies. The tests will ask about fatigue, stress, mood, pain, daily activities, and family support. The imaging studies will measure brain function at rest and during activity. - Companions will have a medical history and physical exam. They will also complete several questionnaires about themselves as well as the service member/veteran. The tests will ask about fatigue, stress, mood, pain, daily activities, and family support....
The primary objectives of this study are to assess whether participants with traumatic brain injury (TBI) administered glyburide begun within 10 hours of injury will show a decrease in magnetic resonance imaging (MRI)-defined edema and/or hemorrhage, compared to placebo and to assess the safety and tolerability of glyburide compared to placebo in participants with TBI. The secondary objectives include analyzing brain cell loss, computerized tomography (CT) scan /MRI abnormalities, reduction of mortality and or improvement of function or physiology, incidence of decompression craniectomy, incidence of neuroworsening, and to assess the steady state concentrations of glyburide in TBI participants.
Tampere Traumatic head and brain injury study is a prospective study aiming to explore neuroradiological, neuropsychological, neurological and biochemical aspects of mild traumatic brain injury (mtbi). The main interest is on factors that effect to the outcome after mtbi. The study is conducted in Tampere University Hospital's emergency department between the 1st of August 2010 and 31st of July 2013.
The primary objective of this study is to evaluate the utility of the Banyan UCH-L1/GFAP Detection Assay as an aid in the evaluation of suspected traumatic brain injury (Glasgow Coma Scale score 9-15) in conjunction with other clinical information within 12 hours of injury to assist in determining the need for a CT scan of the head.
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.
The purpose of this study is to obtain evidence of safety and determine the pharmacokinetics (PK) of NNZ-2566 in healthy volunteers, when administered orally.
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 is an exploratory qualitative interview study being conducted with a primary objective of examining perceptions held by active military and veterans regarding help-seeking attitudes and mental health beliefs which influence the decision to consent or decline participation in Post-Traumatic Stress Disorder (PTSD) or Traumatic Brain Injury (TBI) clinical trials. Active duty military and/or veterans aged 18 years and older who consent to participate (N = 50), or have recently declined participation (N = 50), in an INTRuST affiliated outpatient clinical trial for deployment-related PTSD or TBI will be recruited. Participants who consent to participate in an INTRuST clinical trial (Group 1) will be interviewed once at the beginning the of the clinical trial, and again following participation in the trial. Participants who decline participation in an INTRuST affiliated outpatient clinical trial (Group 2) will be interviewed once. For participants in both groups, study participation will initiate within 1 month of referral to study. Total duration of study participation is based on the specific clinical trial that the participant is recruitment from; the longest trial is estimated to be 24 weeks or less. Semi-structured qualitative individual interviews will be conducted to carry out a thematic analysis of the data exploring familial, social and institution-level constructs which may influence the subjective experience of the research treatment process.
This is a case series study evaluating the feasibility and dosage of Intensive Mobility Training (IMT). Twelve participants with chronic, mild-to-moderate, Traumatic Brain Injury (TBI) causing significant locomotor impairment, who meet these specific criteria, will be recruited. Location and nature of neural insult will be determined by multimodal Magnetic Resonance Imaging (MRI) exam. All participants will receive 3 hours of rehabilitation per day for 20 days, focusing on gait and balance. Locomotion and balance will be comprehensively tested prior to IMT, after 10 days of IMT, and then again after the full dose of IMT. This study will determine the feasibility of this intervention in the population of TBI patients, allow an estimate of effect size and provide initial information on possible neural predictors of success. Furthermore the investigators will be able to determine whether the dosage of 10 days is sufficient or whether significant improvements are made with 20 days of the intervention.
