Filter by:This study will determine if allopregnanolone (ALLO) improves depression and pain symptoms in patients who have a history of mild traumatic brain injury (TBI) [primary endpoints]. The investigators will also determine if ALLO improves functional outcome [secondary endpoint]. Participants in this study will receive an intravenous infusion of either ALLO or placebo. Behavioral assessments will be conducted during the infusion and at several time points post-infusion.
Physical activity and exercise have traditionally not been much of a focus in treatment of postconcussion symptoms and posttraumatic headache. On the contrary, patients have often got advice to rest until they were free from symptoms. This approach, however, is challenged, and complete rest should probably be discouraged after the first 24-72 hours. Moderate aerobic exercise has been found promising in the early phase after sports-related concussion, and in the treatment of patients with headache. This study is an open pilot-study of guided, home-based exercise in a clinical sample with postconcussion symptoms and posttraumatic headache after mixed-mechanism mild traumatic brain injury and minimal head injuries. The study will result in data about the feasibility and possible effects of exercise as treatment for prolonged postconcussion symptoms and posttraumatic headache.
The objective of this study is to show that the measurement of auditory and vibro-tactile evoked potentials, or the recording of the EEG signal during a motor imaging task, can be used in routine clinical situations to explore the state of consciousness of subjects in Non-responsive Awakening (or Chronic Vegetative State) or in Minimal Consciousness (or relational state) after a severe brain injury. Assumptions : - Correlation between patient response rates obtained with the brain-machine interface and their clinical consciousness score (Coma Recovery Scale Revised score) - Differentiation of the parameters of the evoked potentials P300 between patients in a vegetative state and those in a state of minimal consciousness
Background: People who have had a traumatic brain injury (TBI) often experience fatigue. Fatigue is the feeling tired all the time. Researchers want to learn more about how TBI and fatigue are related. Objective: To better understand fatigue after TBI in active duty military and veterans. Eligibility: Active duty service members or veterans ages 25-40 who have sustained at least 1 TBI more than 6 months but less than 5 years ago Design: Participants will be screened with: - Medical history - Physical exam - Blood and urine tests Participants will have Visit 1 the same day as screening. This will include questionnaires and interviews. These will be about their fatigue, quality of life, and health. Participants will wear an activity monitor on their wrist and complete a sleep diary for 7 days at home. Participants will have Visit 2: They will stay in the clinic for 2 nights. The visit will include: - Tests of memory, attention, and thinking - Placement of intravenous (IV) line: A needle will guide a thin plastic tube into the participant s arm vein. - 2 overnight sleeps tests: Participants brain waves will be recorded while they sleep. Small electrodes will be placed on the scalp. Monitors will be placed on the skin. These will measure breathing, heart rate, and movement. Blood will be drawn overnight through the IV line. - Optional hydrocortisone stimulation test: Participants will receive the hormone through the IV line. Blood will be drawn through the IV line 5 times over 1 hour. - Optional MRI: Participants will lie in a machine. This machine is a metal cylinder that takes pictures of the brain.
To investigate the effectiveness of a peer-led group intervention compared to a staff-led activity group to improve social communication skills for people with severe acquired brain injury (ABI).
This proposal will examine measures of neuroplasticity (the brain's ability to alter its function or structure in response to changes in the environment or novel experiences) in Veterans with schizophrenia or traumatic brain injury (TBI). Both conditions are associated with impaired cognition (for example, attention, memory, learning), which is in turn associated with poor community functioning and integration. However, the two disorders differ in their origins: schizophrenia is a neurodevelopmental disorder appearing usually in late adolescence while TBI is an acquired disorder as the result of an injury to the head. Understanding of the root causes of complex cognitive impairments associated with these disorders remains limited. Neuroplasticity is a fundamental brain process that underlies cognitive functioning and may give insight into the causes of cognitive dysfunction in TBI and schizophrenia. Neuroplasticity will be measured using electroencephalography (EEG) by placing small electrodes on the scalp that record the brain's electrical activity. Participants will listen to simple auditory tones and view simple visual patterns while their EEG is recorded. Additionally, participants will have measures of cognition and clinical interviews for diagnosis of a disorder as well as any current levels of symptoms.
This is a pilot randomized controlled trial (RCT) for Veteran participants with alcohol use disorder co-occurring with mild traumatic brain injury and/or post-traumatic stress disorder. The treatment intervention is repetitive Transcranial Magnetic Stimulation (rTMS) and the goal is to reduce alcohol craving with this treatment. The study will enroll 20 Veteran participants. Half of these participants will receive real rTMS and half of the participants will receive placebo rTMS. rTMS treatment will be provided over 10 sessions that will occur once every weekday for 2 weeks. Veteran participants will then complete follow-up phone calls to further evaluate alcohol craving and other symptoms.
The purpose of this study is to determine whether a single treatment with administration of 400 Units NT 201 (botulinum toxin) is superior to placebo (no medicine) for the treatment of lower limb spasticity caused by stroke or traumatic brain injury (Main Period). Participants will be assigned to the treatment groups by chance and neither the participants nor the research staff who interact with them will know the allocation. The following 4 to 5 treatment cycles will investigate the safety and tolerability of treatment with NT 201 (botulinum toxin) when administered in doses between 400 and 800 Units (Open Label Extension Period). All participants will receive the treatment and the dose will depend on whether only lower limb spasticity or combined upper and lower limb spasticity are treated.
The goal of this randomized controlled trial will be to show that the use of a novel automated system to guide vasopressor administration in brain injury patients will results in more time spent with a mean arterial pressure (MAP) within the predefined MAP (+/- 5 mmHg of the target MAP) compared to patients managed without any automated system (manually management)
Individuals will be recruited from the VA Portland Health Care System and the community affiliated with Oregon Health & Science University. Traumatic brain injury status will be assessed as a contributing factor. Subjects will be randomized to one of 3 groups (BCAA or one of 2 placebo conditions) and instructed to consume study product twice daily for 21 days. Self-report questionnaires, wrist actigraphy, pressure pain testing, and cognitive function will be assessed pre and post the experimental period.
