TBICoE supports a network of military hospitals and clinics and Department of Veterans Affairs medical centers with traumatic brain injury research initiatives, including gap-driven analyses and congressionally directed programs such as the Section 721 Longitudinal Study of TBI and Section 734 investigation into the effects of blast exposure on Warfighter Brain Health and Performance.
TBICoE's extensive internal and external collaborations allow for clinical innovation and research along the continuum of care of TBI—from initial injury to acute and post-acute medical settings; rehabilitation; and ultimately a return to family, community, and work or continued duty.
Beyond conducting research, TBICoE periodically reviews available peer-reviewed scientific literature to summarize the state-of-the-science, consensus of medical approaches, as well as existing and new evidence of TBI research. These research reviews, information papers, and the NEW Clinical Pearls resources are available for download.
TBICoE Research Gaps and Priorities (2022-2024)
- Determine the cumulative effects of multiple concussive or sub-concussive exposures or events, on acute and long-term physical, psychological, and cognitive outcomes.
- Determine the prevalence of brain injuries within the military and identify environmental risk factors and variables in various settings (operations, weapons training, combatives, parachute training, etc.).
- Determine the relationship(s) between adverse brain health outcomes resulting from brain injury and/or brain exposures (e.g. blast, blunt, accelerative, and directed energy) and potential co-occurring/influential individual factors, including (but not limited to): health conditions, genetic factors, psychological factors, stress, chronic pain, and substance overuse/dependence.
- Define the chronic/long-term effects which result from brain injury and/or exposure(s) that mayor may not lead to a clinical diagnosis that may influence occupational performance and military readiness in warfighters. This includes the dose/response relationship between exposure(s) and these long-term outcomes and age-related decline or neurodegenerative diseases.
- Determine the mechanisms underlying neuroprotection and cognitive enhancement following brain exposure(s) or brain injury and adapt or refine the use of cognitive performance improvement tools, capabilities, and supplements for the warfighter.
- Evaluate neurocognitive assessment tools and validated metrics that enable an accurate understanding of a warfighter’s cognitive readiness for military activities and readiness requirements.
- Determine the utility and effectiveness of novel TBI treatments, assessments, diagnostic and clinical decision-support tools, and technologies based on objective measures (e.g., biomarkers, sensory system status, neuroimaging changes, and neurocognitive status), all with the aim of supporting care in any environment, including future operations.
- Reliably predict symptom trajectory and variables associated with treatment response for mild TBI patients with common co-occurring conditions (e.g., PTSD, depression, insomnia, etc.).
- Define and mitigate the acute effects of brain injury or exposures that can prevent warfighters from returning to optimal brain health required for military service.
- Evaluate and prioritize novel treatments for TBI, and determine optimal categorization of treatment courses based on symptom subgroups/clusters (e.g., vestibular, headache, PTSD, and psychological health or cognitive).
TBICoE Information Papers
Neurodegenerative Diseases and Traumatic Brain Injury
The long-term effects of TBI are unknown, but there is concern that there may be an association with neurodegenerative diseases years after the injury. The intention of this information paper is to summarize the available evidence for or against an association of TBI with 3 of the more common neurodegenerative diseases, Alzheimer’s Disease, Parkinson’s Disease, and Amyotrophic Lateral Sclerosis.
Download this information paper to learn more about neurodegenerative diseases and TBI.
The Impact of Mild Traumatic Brain Injury on the Autonomic Nervous System
The purpose of this information paper is to provide a general overview of the current evidence related to the impact of concussion, or mild traumatic brain injury, on the autonomic nervous system. This paper will focus on heart rate variability, pupillary light reflex, and hyperhidrosis within the military and civilian populations.
Download this information paper to learn more about the state-of-the-science of how the autonomic nervous system is impacted by mild TBI. Researchers and clinicians can learn about current tools used to measure ANS and their current clinical utility at this time.
TBICoE Research Reviews & Clinical Pearls
The following TBICoE research reviews are fluid areas of investigation and provide an overview on specific topics of interest related to TBI research. These reviews will be updated as new research emerges.
New in 2023, research reviews will be complemented by a supplemental resource, "Clinical Pearls." Both the research review and clinical pearls products are created for both the researcher and the military clinician.
Mild TBI and Posttraumatic Stress Disorder Research Review
This research review provides an in-depth summary of the available clinical research on the topic of co-morbid mild traumatic brain injury and posttraumatic stress disorder. Specifically, this review will address symptoms, anatomy, diagnosis, and treatment of mild TBI, PTSD, and the unique circumstances associated with the presentation of both.
Mild TBI and Posttraumatic Stress Disorder Clinical Pearls
This new supplemental product to the detailed research review is designed to be brief and provide key actionable “clinical pearls” that should be considered in the treatment of service members with comorbid mild TBI and PTSD.
Chronic Traumatic Encephalopathy Research Review and Fact Sheet
Revised in March 2023, the research review addresses the current state-of-the-science of CTE, including an in-depth look at available peer-reviewed scientific literature and a bulleted quick-reference summary for clinicians and the operational community. The revised fact sheet is a quick reference for researchers, the operational community, and clinicians to understand what is known, and not known, about CTE.
In cases with confirmed CTE, there is noteworthy overlap of symptomology and comorbid neuropathological conditions. CTE currently cannot be diagnosed in living persons. The clinical syndrome for living persons, Traumatic Encephalopathy Syndrome, is associated with CTE but is not diagnostic of the condition.
Multiple Traumatic Brain Injury/Multiple Concussion
Prior history of TBI may predispose an individual to increased risk of subsequent TBI when exposed to less force, and may engender lengthier recovery from postinjury symptoms. Activities such as contact sports and military service carry particular risk for multiple TBI. In addition to acute postinjury difficulties, cumulative TBI may increase the risk of chronic cognitive and functional impairment. Conservative management of postinjury symptoms as part of a medically monitored, progressive plan for returning to activities is recommended for individuals with a history of TBI.
TBICoE Congressional Reporting
Many of TBICoE’s drivers include mandates from Congress within the National Defense Authorization Act (NDAA). In response to and in accordance with the requirements of these mandates, a number of reports have been submitted to Congress and are available in the public record.
