Filter by:The goal of this study was to investigate the biomarkers, neurofilament light chain, inflammatory markers, calcitonin-gene-related peptide, and metabolites from the kynurenine pathway in patients with severe post-concussive symptoms. The main question it aimed to answer was: - Are the biomarker concentrations significantly changed in patients with severe post-concussive symptoms compared to healthy individuals? - Do the biomarker concentrations change at follow-up? Participants were recruited from a recently published randomized controlled trial (Clinicaltrials.gov no. NCT02337101 / PMID: 31891145 ). The biomarker concentrations were compared to a healthy control group recruited from the Blood Bank at Aarhus University Hospital in 2022.
This study will evaluate neurofeedback (NFB) training as a low risk, non-invasive, effective treatment for Veterans diagnosed with mild traumatic brain injury (mTBI) and experiencing chronic post-concussive symptoms (PCSs). It is being funded by the Department of Veterans Affairs. Doing this study will help to determine if NFB will reduce chronic headaches and enhance sleep, attention and quality of life in Veterans with mTBI. NFB is like other biofeedback processes in which information about a person's specific body functioning is made known to the person through a special computer program, which can help that person make the specific body function work better through training. This type of training is usually fun and easy with the help of a coach and a computer. Nothing is ever put into a person's body with biofeedback and it is natural and safe. When a person becomes focused, calm and alert while training on an NFB system, the computer will recognize this and let the trainee know by automatically displaying on the computer screen the positive progression of the game they are playing, such as the plane moving forward or a flower opening. The brain really likes to be in this pattern and when it is happening, people feel good. As a result, any discomforts, like headaches or insomnia, experienced may decrease. After learning about the study, Veterans who agree to participate will be randomly placed into one of two groups, either an intervention group (who will receive NFB) or a control group (who will receive only usual care plus once a week 15-minute calls on health topics). Veterans will have an equal chance of being in either group. Those placed in the control, will also receive NFB after completion of the control group activities. Veterans who are placed in the intervention or delayed intervention group will receive NFB up to 5 times a week, but usually 3 times a week for a total of 20 sessions. Each session is an hour long. Both the intervention and control group will participate in four assessment sessions (lasting up to 2 1/2 hours each) that involve completing 12 questionnaires and a 20-minute attention evaluation. The assessment sessions will occur at the beginning of the study, at 4-6 weeks, at 8-10 weeks, and 2-months later. The participant will receive financial compensation for taking the baseline assessment, 4-6 week, 8-10-week assessments, and for the 2-month follow-up assessment. A participant will receive financial compensation for gas, time and valet parking for each intervention and assessment session. Participation in this research will last about 4 months for those in the intervention and 8 months for those in the delayed intervention group. All participants will receive the NFB treatment by the end of the study. A person who participates in this study may experience a reduction in his or her chronic headaches, and an enhancement of sleep, attention and quality of life. There may be a worsening of symptoms until the individualized training plan for a person can be identified. During an NFB session, brief moments, lasting only seconds or minutes, of dizziness while sitting, muscle tension, or tingling may be experienced. Most people feel relaxed and calm during and after NFB training. This project will be an important step towards a broader implementation of an evidence-based treatment solution for Veterans experiencing chronic headaches, insomnia and attention disorders. The experience of these chronic symptoms can lead to debilitation in all areas of Veterans' lives. This project will provide evidence for the use of NFB with Veterans to alleviate their chronic symptoms and enhance their quality of life. If supported, NFB will offer the investigators' Veterans an effective and non-invasive treatment option. NFB is a patient focused intervention that enables Veterans the opportunity for self-health management.
The goal of this study is to investigate when is the best time to resume physical activity following a head injury. Two treatment plans will be studied; the first treatment plan consists of gradually reintroducing physical activity in the child's routine, starting 72 hours following the head injury. The second treatment plan involves physical and mental rest until the child as no more symptoms. Once symptom free, physical activity is gradually reintroduced in the child's routine.
Patients with mild-moderate traumatic brain injury (TBI) sustained between 3 months and 5 years ago with prolonged postconcussive symptoms will be recruited. On Day 1 of the study they will undergo neuropsychological (NP) testing. They will then undergo 10 days of Left dorsolateral prefrontal (DLPFC) anodal transcranial direct current stimulation (TDCS) (active or sham) combined with cognitive training. On day 10 NP testing will be obtained again. On Day 30, NP testing will be repeated a 3rd time. At 6 months and 1 year, quality of life, depression, and post concussive symptoms will be assessed.
PURPOSE: The long-term goal of this line of research is to develop rational, biologically based evidence for the treatment of post-concussion syndrome (PCS) in children. The objective of this application is to examine the effect of melatonin on the symptoms of PCS and its neurobiology using integrated neurodiagnostic techniques in children. OVERVIEW: PCS is a constellation of clinical symptoms including physical (i.e. headaches), cognitive (i.e. memory), and behavioral disturbances. PCS is associated with significant morbidity in the child and his/her family), and yet there are no evidence-based medical treatments available. This suggests an urgent need to develop novel treatment options to improve outcomes for children suffering from PCS. Melatonin has several relevant mechanisms of action, and neuroprotective effects. Recent research suggests that the explanations for persistent PCS symptoms may be due to alterations in neurotransmissions and neuronal circuitry, particularly involving the dorsolateral prefrontal cortex (DLPFC). Investigators have two specific aims: 1. To determine if treatment with melatonin improves PCS in children following mild traumatic brain injury. Hypothesis: treatment of mTBI children with PCS with 3mg or 10mg of oral melatonin for 28 days will result in a decrease in PCS symptoms as compared with placebo. Effects will be dose-dependent and may be independent of sleep effects. Methods: A randomized double blind, placebo controlled trial (RCT); Outcome measure is a PCS symptom questionnaire. A subsequent RCT will then be performed using the optimal melatonin dose at a second centre. 2. To understand the neurophysiological mechanisms of paediatric PCS and assess any resultant effects of treatment with melatonin. Methods: A case-controlled study within the RCT, using functional MRI and Transcranial Magnetic Stimulation to investigate the neurophysiological properties of paediatric mTBI before and after treatment; Treatment groups from the RCT will be compared with two control groups: i) normal controls and ii) asymptomatic mTBI children. SIGNIFICANCE: This study has the potential to 1) provide a safe and effective treatment for PCS and 2) will provide valuable information about the neurophysiological properties of the brain associated with PCS following mTBI in children and how these change with symptom resolution.
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).
The purpose of this project is to explore the degree to which performance consistency on neuropsychological measures varies in a sample of Operation Iraqi Freedom (OIF)/Operation Enduring Freedom (OEF) Veterans with a history of mild traumatic brain injury (mTBI) with persistent self-reported symptoms.
This is a Phase II randomized trial designed to describe the magnitude of change between baseline and follow-up outcomes for symptom surveys and a battery of neuropsychological tests administered at time points corresponding before and after 10 weeks over observation in four groups: - A military population with post-concussion syndrome (mTBI) receiving local standard care - A military population with post-concussion syndrome (mTBI) receiving local standard care and sham hyperbaric oxygen sessions - A military population with post-concussion syndrome (mTBI) receiving local standard care and hyperbaric oxygen at 1.5 atmospheres sessions - A otherwise similar group with PTSD but no history of TBI receiving local standard care Differences and variability of the tests will be used for determining the optimum primary endpoint(s) for future trial, as well as for refinement of sample size and power calculations for these studies. The groups undergoing hyperbaric sessions will be assigned to receive HBO2 or sham using a randomized, double blind design. Active duty military (Army, Marine, Navy, Air Force) men and non-pregnant women residing in the United States and who will remain in the military for the entire study period, aged 18-65 years who have been deployed one or more times to the US Central Command since the initiation of Operation Enduring Freedom (October 7, 2001) who either: - have been diagnosed with Post Traumatic Stress Disorder (PTSD) as a result of traumatic events that occurred during the qualifying CENTCOM deployment, but have no diagnosed or suspected lifetime brain injuries resulting in loss or alteration of consciousness; OR - have been diagnosed with at least one mild brain injury (mTBI) with persistent (> 4 months) symptoms sustained during one or more of those deployments
The overall hypothesis is that the long-term cognitive and behavioral sequelae of traumatic brain injury (TBI) are due to selective disruption of the long association white matter tracts of the cerebral hemispheres, with resulting functional impairment of the network of cortical regions that are interconnected by these long-range association pathways. We propose that traumatic white matter injury can be measured with diffusion tensor imaging (DTI) and that the impaired cortical activation can be detected with magnetoencephalography (MEG), and that the results of these imaging examinations will correlate with neurocognitive status and functional recovery after TBI.
