Transforming Research and Clinical Knowledge in Traumatic Brain Injury Epileptogenesis Project (TRACK-TBI EPI)
Study Overview

Detailed Description
This longitudinal observational study is part of the Transforming Research and Clinical Knowledge in Traumatic Brain Injury (TRACK-TBI) initiative, a multi-institutional project designed to characterize the acute and longer-term clinical, neuroimaging, and blood biomarker features of TBI. TRACK-TBI enrolled TBI patients at 18 Level 1 Trauma Centers in the US, across the age and injury spectrum. This study will extend the follow-up period for TRACK-TBI participants. The extensive clinical, imaging, and biomarker data that has already been collected in these TRACK-TBI participants, in combination with the extended longitudinal data, will allow for the identification of risk factors, co-morbidities, and prognostic biomarkers of TBI. Consequently, the extension of study follow-up will help to determine negative neurological and psychological outcomes of individuals who experienced a TBI compared to healthy and orthopedic controls.
The TRACK-EPI project aims to address the gaps in the existing literature and in the TRACK project regarding PTE. Post-traumatic epilepsy (PTE) is a common complication of traumatic brain injury (TBI), occurring in up to 20% of civilian patients and as many as 50% of military service members who suffer severe brain trauma, and 3-5% of those who suffer moderate TBI. Epilepsy resulting from brain trauma is often difficult to control with medical therapy, and is the cause of epilepsy in approximately 5% of patients referred to specialized epilepsy centers. PTE can be the result of TBI of any severity, although the risk is higher from severe TBI. PTE can arise through a variety of mechanisms, which may co-exist within a single patient. Focal brain injury, which results from penetrating trauma or focal contusions can result in epileptogenesis. Closed head injury can also produce diffuse injury, with shearing of axons and blood vessels, diffuse edema and ischemia, and secondary cellular damage through the release of inflammatory mediators. The clinical features of epilepsy, such as the frequency and severity of seizures, prevalence of associated co-morbidities, and responsiveness to therapy, may differ among these diverse mechanisms. Additionally, the neurophysiologic and imaging features of epileptogenicity also likely differ. Given the frequency of PTE, a more complete understanding of PTE etiology and prognosis is vital. Furthermore, it is likely that a sophisticated understanding of the subtypes of epilepsy resulting from brain trauma will be required to successfully develop anti-epileptogenic therapies.

Cohorts and Interventions
Group / Cohort |

---|---|
Comprehensive Assessment Battery (CAB)
Participants who demonstrate decision-making capacity will be asked to complete the Comprehensive Assessment Battery (CAB).
The CAB in-person is comprised of measures of cognition (i.e.
attention, memory, information processing speed, executive functions), mood (i.e., depression, anxiety), social participation, subjective well-being, post-traumatic stress, interviews, global functional status measures, and a COVID-19 questionnaire.
|
Assessments will be administered to evaluate participant outcome status
Participants will be asked to complete a 3T MRI
Blood Draw for Plasma, DNA, Serum, RNA
Patients who screen positive for PTE will have an in-depth clinical visit
An EEG will be performed on patients who screen positive for PTE at the clinical visit
|
Abbreviated Assessment Battery (AAB)
Participants who do not have decision-making capacity will be asked to complete a modified assessment battery, called the Abbreviated Assessment Battery (AAB).
The AAB in-person assessment will administer the Speech Intelligibility, GOAT, and CAP and/or CRS-R to study participants.

|
Telephone Assessment Battery
TRACK-TBI participants may complete up to three annual telephone calls to assess outcome status and screen for PTE.
These assessments will determine eligibility for the in-person study visit.
|
Assessments will be administered over the telephone to evaluate participant outcome status and screen for PTE

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Glasgow Outcome Scale Extended (GOSE)
Time Frame: 4-6 years after TRACK-TBI enrollment
|
The GOSE provides an overall measure of functional status based on information on cognition, independence, employability, and social/community participation collected via structured interview.
Individuals are described by one of the eight outcome categories: Dead (1); Vegetative State (2); Lower Severe Disability (3); Upper Severe Disability (4); Lower Moderate Disability (5); Upper Moderate Disability (6); Lower Good Recovery (7) and Upper Good Recovery (8).
Good Recovery is defined as a score of 7-8, Moderate Disability is defined by a score of 5-6 and Severe Disability is defined by a score of 3-4.

4-6 years after TRACK-TBI enrollment
|
Diagnostic Interview for Seizure Classification Outside of Video EEG Recording (DISCOVER)
Time Frame: 4-6 years after TRACK-TBI enrollment
|
During the clinical evaluation, participants and their caregivers are educated about the heterogeneous and protean manifestations of epileptic seizures, and encouraged to contact study staff if seizures or seizure-like events are noted.
The DISCOVER form has been found to be highly accurate when compared to gold-standard video-EEG recording in an Epilepsy Monitoring Unit for classifying seizures
