Paired VNS For TBI Rehabilitation

This study is evaluating whether pairing vagus nerve stimulation (VNS) with structured upper limb rehabilitation therapy can improve arm and hand function in individuals with chronic moderate to severe traumatic brain injury (TBI) and subsequent motor deficits. Many people who survive a TBI experience long-term weakness, poor coordination, and difficulty using one arm or hand. These motor impairments can significantly affect independence and quality of life. Traditional rehabilitation can help, but recovery is often incomplete. Vagus nerve stimulation (VNS) is an FDA-approved therapy for certain neurological conditions and involves a small device implanted under the skin in the chest with a lead connected to the vagus nerve in the neck. The device delivers mild electrical pulses to the nerve. In this study, VNS will be paired with goal-directed upper limb rehabilitation exercises. The stimulation is delivered during specific movements in therapy sessions. This "paired stimulation" approach is designed to enhance neuroplasticity - the brain's ability to reorganize and form new connections - which may improve motor recovery. The VNS device used in this study is FDA-approved for other conditions. However, its use paired with rehabilitation for upper limb recovery after traumatic brain injury is investigational. Participants in this study will: Undergo surgical implantation of the VNS device. Participate in structured upper limb rehabilitation therapy sessions where stimulation is paired with specific movements. Complete follow-up visits and assessments to measure changes in arm and hand function, strength, dexterity, and overall recovery. The main goal of the study is to determine whether paired VNS and rehabilitation improves upper limb motor function compared to rehabilitation alone. Safety will also be closely monitored, including surgical outcomes and any device-related effects. This study may help determine whether VNS paired with rehabilitation is a safe and effective way to enhance motor recovery after traumatic brain injury. Findings from this research could contribute to improved treatment strategies for individuals living with long-term motor impairments following TBI. If the results are promising, future studies plan to also include patients with acute TBI. Participation is voluntary. All participants will be carefully evaluated to determine eligibility, and informed consent will be obtained before enrollment.

Cervical Transcutaneous SCS for TBI

The goal of this study is to test the effects of non-invasive electrical stimulation of the spinal cord (called transcutaneous spinal cord stimulation, or tSCS) on arm and hand movement in people with motor impairments after a traumatic brain injury (TBI). Specifically, tSCS will be delivered using adhesive electrode pads placed on the skin over the upper back. The research team will measure how tSCS affects strength, movement control and muscle spasticity using different tests. Results of this study will help develop future treatments using an implanted (invasive) form of spinal cord stimulation to improve arm and hand function, helping people with TBI become more independent and improve their quality of life.

The goal of this study is to learn whether a home-based rhythmic auditory stimulation (RAS) program using the MR-001 device can help improve walking, balance, and other health outcomes in adults with moderate to severe traumatic brain injury (TBI). The study will also look at how safe and feasible it is for people with TBI to use this device at home. The purpose is to determine the safety, feasibility, and adherence of a home-based, music-guided RAS intervention and to explore preliminary effects on mobility, cognition, mood, enjoyment, perceived change, and cortical excitation. The main questions this study aims to answer are: 1. Does training with the MR-001 device improve walking endurance, gait speed, and balance? 2. Does the intervention improve cognition, mood, fatigue, and participants' impression of change? 3. How enjoyable is the training experience for participants? 4. How does the brain respond to walking with versus without rhythmic auditory stimulation? Researchers will compare the MR-001 intervention to a waitlist control group to see whether the device leads to improvements beyond usual activity. Participants will: 1. Use the MR-001 device at home for 30 minutes, three times per week for eight weeks 2. Complete walking, balance, cognitive, and questionnaire assessments 3. Participate in two lab sessions using functional near-infrared spectroscopy (fNIRS) to measure brain activity during walking 4. Provide two fasting blood samples to measure BDNF, a biomarker related to neuroplasticity 5. Complete study visits at baseline, after eight weeks, and (for the waitlist group) after their treatment period This study will help determine whether a home-based, music-guided walking program can support long-term mobility and recovery after TBI.

Cognitive Rehabilitation for Victims of War and Related Traumas With Traumatic Brain Injury and Cognitive Impairment

Researchers at Massachusetts General Hospital are looking to see if a program created to help improve thinking and memory can work for people affected by trauma, including asylum seekers and refugees, survivors of intimate partner violence (IPV) and others with traumatic brain injury (TBI). They're checking if this program is practical and if people find it helpful. The study will have two groups. Participants will complete a first questionnaire and then be assigned to a group by chance. One group will participate in the program immediately and then answer the second questionnaire (approximately 3 months after the first questionnaire they did). Then they will wait and then answer the third and final questionnaire approximately 6 months after the first one. The second group will wait and answer the second questionnaire approximately 3 months after the first one. Then they will receive the program and answer the third and final questionnaire (approximately 6 months after the first one they did.)

The goal of this clinical trial is to learn if combining suvorexant (a sleep medication) with a shorter form of prolonged exposure therapy called PE-PC works to treat PTSD symptoms and improve sleep in Veterans and military personnel with PTSD and insomnia, with and without mild-to-moderate traumatic brain injury (TBI). The main questions it aims to answer are: Does suvorexant, when combined with PE-PC therapy, reduce PTSD symptoms more than PE-PC with a placebo (a look-alike substance that contains no drug)? Does suvorexant, when combined with PE-PC therapy, improve psychosocial and physical functioning more than PE-PC with a placebo? Researchers will compare PE-PC combined with suvorexant to PE-PC combined with a placebo to see if adding suvorexant improves PTSD symptoms, sleep, and overall functioning in Veterans. Participants will: Receive weekly PE-PC therapy sessions for 8 weeks Take suvorexant (10-20 mg) or a placebo each night during the 8-week treatment period. Complete repeated assessments of PTSD symptoms, sleep, and psychosocial and physical functioning throughout the study.

Brain Development in Young Children Following Mild Traumatic Brain Injury - Pilot Study

Concussions (also known as mild traumatic brain injury) are common in young children. In some children, they can lead to short- and long-term difficulties. However, our knowledge of the exact consequences of injuries on young children's brains and behavior is limited. These consequences may be different in children under 6, as their brains are fragile and undergoing significant developmental changes. The aim of this study is to determine the extent to which a concussion sustained before the age of 6 years is associated with changes in young children's brain structure, function and behaviours, using a brain imaging. In this study, the results of a group of 30 children with a concussion will be compared to those of 30 children of the same age with an orthopaedic injury to the upper or lower limbs.

Augmented Renal Clearance in Neurocritical Care

Stroke, severe brain injury, uncontrolled seizures and brain infections are the most common life-threatening neurological illnesses in the world with an estimated combined annual hospital management cost of up to 44 billion dollars. Seizures and infections are common complications following acute neurological illnesses and contribute significantly to poor outcomes if not promptly treated with appropriately dosed anti-seizure medications and antibiotics, respectively. Limited research suggested that many of those patients present with a phenomenon called augmented renal clearance (ARC) or, in other words, enhanced kidney function. ARC may have a significant influence on how medications are removed from the body potentially resulting in insufficient doses and treatment failure. Therefore, patients with ARC require higher medication doses; however, ARC is largely undetected using kidney assessment methods currently used in practice. In addition, it is not clear how medications should be dosed in those with ARC. The majority of ARC research has not focused on patients with life-threatening neurological illnesses. Thus, clinicians are likely under-dosing vital medications in those patients, and completely unaware. There is an immediate need to address the gap in knowledge. Therefore, this research aims to characterize the phenomenon of ARC in patients with life-threatening neurological illnesses through identifying the frequency, duration, contributing factors and clinical impact of ARC. Adult patients admitted to the neurosciences intensive care unit for life-threatening neurological illnesses will be enrolled in the study. Urine and blood samples wil be collected from participants to determine the presence of ARC and identify its contributing factors. In addition, blood samples will be collected from participants treated with select antibiotics and anti-seizure medications to determine their concentration and propose dose adjustment in those with ARC. This research is expected to improve the care of patients with life-threatening neurological illnesses through efficient identification and monitoring of patients exhibiting ARC facilitating timely medication dosage optimization. Furthermore, recommendations of optimal doses of commonly used medications in patients with ARC would improve the likelihood of treatment success with potential to improve patients' health and wellbeing.
