Early Digital, Analyte and Neurologic Biomarkers of Acute and Chronic Brain Injury and Recovery in CQT Instructors

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

Repetitive blast exposure has been shown to lead to more severe neurobehavioral impairments versus a single exposure. Blast-induced Traumatic Brain Injury (TBI) can lead to short- and long-term adverse outcomes Even mild brain injuries can impair neurocognitive performance, and repeated injuries can amplify negative outcomes. Service members with repeated exposure to low-level blasts as a necessary part of their job or training display altered neural activity during a memory task that is paralleled by a reduction in accuracy on neurocognitive memory tasks. As a result, it is important to monitor service members that are exposed to multiple blast-generated mTBIs to allow the earliest identification of acute or chronic brain and body insult and provide individualized measures of time to recovery. While TBI is clinically diagnosable, the methods of diagnosis have up to now been typically expensive and immobile, and treatments and interventions sparse. The investigators will conduct a longitudinal assessment of mTBI brain biomarkers by collecting repeated measures of FDA approved mTBI brain injury biomarkers, correlated with sound and blast exposure, as well as continuous monitoring through smart watches (activity, sleep, biometrics, calorie expenditure, balance) and analyte data through analyte sensors (glucose, lactate, ketones). Study data will be organized into categories and presented to participants daily within the application and will be securely stored within the application. At the completion of the study, participants will be provided with the study data digitally within the mobile application and study data will also be provided to the credentialed unit medical provider to enable it to be ported to the participants' electronic medical record. This study will create a continuous record of blast overpressure and sound exposures and correlate those to the participants health state over the course of several 9-week courses. This will enable an assessment of individualized susceptibility to brain injury as well as providing novel data on time to recovery. The investigators hope to develop dynamic and accurate risk profiles that are individual and will lead to further understanding of how to protect participants from mTBI (mild TBI) events.
