Concussion

Concussion or mild traumatic brain injury (mTBI) is a major public health concern. Most adolescents will recover from mTBI without complication; however, a sizeable minority experience symptoms that last more than one most post-injury (i.e., persisting symptoms after concussion). Few evidence-based treatments exist for adolescents with persisting symptoms after concussion. Mindfulness-based interventions (MBIs) are effective for treating a wide range of mental and physical health conditions that overlap with post-concussion symptoms. Participants will participate in an 8-week smartphone app-based MBI or a health education program as a control. The study will determine the practicality of doing a larger study to evaluate the effectiveness of the MBI by assessing participants' level of interest, view of intervention helpfulness, and their completion of all the components of the study.

This study is a randomized, placebo-controlled, double-blinded, therapeutic exploratory clinical trial of branched chain amino acids (BCAAs) in the treatment of concussion. The aim of the study is to determine whether administration of high-dose BCAAs compared to placebo promotes concussion recovery.

The purpose of this study is to investigate the efficacy, safety, and tolerability of two dorsolateral prefrontal cortex (DLPFC) repetitive transcranial magnetic stimulation (rTMS) protocols to alleviate symptoms of depression in United States (U.S.) military service members and veterans with a history of concussion/mild traumatic brain injury (TBI).

Concussion and depression have long been recognized to be intertwined pathologies.1-3 Although female athletes are more likely to suffer from mental health symptoms than males athletes following a concussion,2 research in this area has been largely biased toward males.4 Recently functional MRI (fMRI) studies5 in concussed athletes have established that there are patterns of local alterations in neural connectivity in the frontal cortex that demonstrate anatomic congruency with transcranial magnetic stimulation (TMS) studies that mapped alternations in neural connectivity to functional and somatic symptoms.6 Thus, there is potential that TMS treatment could decrease both symptom profiles, revolutionizing comorbid treatment options. Possible Benefits: Previous studies have showed a 70% remission rate for depression symptoms. It is possible that participants could have improvement in depressive or concussive symptoms after the ONE-D TMS treatment.

This study aims to develop and evaluate biomarkers using non-invasive optical coherence tomography (OCT) and OCT angiography (OCTA) as well as ultra-widefield (UWF) fundus photography to assess the structure and function of the retinal and choroidal microvasculature and structure in persons with mild cognitive impairment (MCI) and Alzheimer's Disease (AD), Parkinson's Disease (PD), or other neurodegenerative disease, diseases as outlined.

The purpose of this pilot study is to: 1. Determine the feasibility of adherence to completing the home cervico-vestibular exercise program following concussion. 2. Investigate the acceptability of the cervico-vestibular home exercise program. 3. Investigate the impact of the cervico-vestibular home exercise program on symptom reduction, return to play, and return to learn 4. Analyze the timing at which a home exercise program is typically prescribed. Participants will be asked to do and keep track of exercises made to help in their concussion recovery over a two-week period. Participants will come back to see their doctor and complete surveys about how easy the exercises were to do and if they liked them.
