Concussion, Mild

The primary objective of this multi-site randomized clinical trial (RCT) is to compare Acceptance and Commitment Therapy Integrated Rehabilitation (ACT) with usual care rehabilitation (CONTROL) in 250 individuals with mTBI-related symptoms attributable to mild traumatic brain injury (mTBI) treated at one of two sites (1) the University of Pittsburgh Medical Center, or (2) the Intrepid Spirit Center, Carl R. Darnall Army Medical Center, Fort Hood, Texas. Both interventions will be delivered weekly over 4 weeks. Assessments will be administered prior to the start of treatment (Baseline) and at 4-weeks, 3- and 6-months following the completion of treatment.

The purpose of this study is to gather pilot data on the effectiveness of daily disposable tinted contact lenses in reducing photophobia (light sensitivity) following a concussion, with the goal of facilitating the return to work or school.

This study is being conducted to determine the clinical safety and efficacy of Pro-2-Cool mediated head and neck cooling when applied after concussion and improved symptomatology among adolescent athletes as quantified by post-concussion symptom severity (PCSS) score.

The goal of this hybrid implementation-effectiveness study is to evaluate the effectiveness (hastened recovery times) and feasibility (fidelity in connecting to concussion specialty care) of a novel mobile health intervention, designed to reduce disparities in access to specialty care through the use of remote patient monitoring (RPM) to facilitate care hand-off from the emergency department (ED) to concussion specialty care. Participants will report their symptoms and activity once daily through RPM chat technology that is linked to their electronic health record and prompts referral to specialty care.

This study will test a portable virtual reality (VR) system with integrated eye tracking called Virtual Eye Rotation Vision Exercises (VERVE). The proposed VERVE platform will deliver vergence therapy in an automated manner. This research will involve 30 non-traumatic brain injury (TBI) binocularly normal (BNC) Veterans and 50 post-traumatic convergence insufficiency (PTCI) Veterans who will undergo Active and Sham therapy (equally divided groups) to determine the effectiveness of VERVE vergence therapy.

Formal MBIs, such as Mindfulness-Based Stress Reduction (MBSR), have been shown to increase resiliency and teach affect regulation. However, these formal interventions may not be suitable for acutely concussed youth as they are costly, not easily accessible (trained therapists are needed), and require commitment from parents and children for in-person weekly meetings and at-home practice of learned skills for 8 to 16 weeks. Further, MBSR programs may not be readily accessible immediately after a concussion. With the increasing use of mobile phones and tablets in youth, mobile health offers a powerful platform for mental health interventions. Advantages of app-based interventions include constant availability, greater access, tailored content, lower cost, immediate delivery, and increased service capacity and efficiency. Therefore, the anticipated benefit is to show the efficacy of a pragmatic and low-cost intervention and reduce barriers to care through a novel, innovative and accessible MBI treatment program. This will have both a benefit to public health and expand our understanding of the impact of MBIs on pediatric recovery.

The purpose of this study is to conduct the first randomized control trial for targeted treatments for concussion in adults 50 years or older. Participants will be enrolled at their first concussion clinical visit (V1) and their second study visit will occur after (up to 7 days) or concurrently with the participant's second concussion clinical visit, typically (but not limited to) between 21-31 days from V1.

The goal of this observational study is to test if a biosensor can accurately measure a blood biomarker in adult patients presenting to the emergency department with concussion. The main questions it aims to answer are: * Does the biosensor measure the blood biomarker of interest with the same accuracy as the current gold-standard assay technique? * Do relationships exist between blood biomarker measurements from the biosensor and any psychological or physical symptoms of concussion? Participants will be asked to provide blood samples at initial visit and 2-, 6-, and 12-weeks after injury while completing questionnaires at each visit, along with a brief (2 min) daily symptom inventory. Researchers will compare the concussion group to a muscle/skeletal injury group to see if measurements from the biosensor are exclusive to concussion.

This research is being done to examine the benefits of a 28 day head cooling intervention on cognition, inflammation of the brain, sleep quality, menstrual symptom interaction, and mood in acutely concussed females. Brain cooling has been shown to cause temporary symptom relief after traumatic brain injury, but its implications for decreasing timeline of full concussion recovery, particularly in females during periods of confounding neuropsychological menstrual symptoms, remains unexplored.

The investigators aim to investigate the impact of interdisciplinary and individually tailored programs for mTBI (concussion) on quality of life and work capacity, both at the conclusion of the program and after 1 and 3 years. The investigators also want to examine whether early intervention is significant by comparing individuals who enter the program between 1 and 3 months post-concussion with those who only start the program more than 9 months post-concussion. Such a study has not been conducted before and can provide valuable insights into long-term effects and the importance of early intervention

The goal of this pilot clinical trial is to assess the feasibility of administering a paced breathing exercise intervention program to children and adolescents in the sub-acute period after concussion, and to document the autonomic function, and symptom severity (post-concussion symptoms, anxiety, sleep) before and after administration of the intervention. Participants will: will be instructed to perform a daily 10-minutes daily paced breathing home-exercise program and to document the daily exercises performed within a performance log, or receive usual care from a concussion follow-up program. A weekly phone meeting will be performed with the participants, to review exercise, providing, specific instructions, and making any necessary adjustments. All participants (intervention and control group) will undergo a second assessment after four weeks following completion of the intervention program. During the second assessment information regarding the intervention feasibility, time to return to school, return to sport, and clear from medication will be collected as well.
