Research at the TBI Center of Excellence

TBICoE supports a network of military hospitals and clinics and Intrepid Spirit 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 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 evaluates 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, the CUBIST podcast, and the new clinical pearls resources are available for download.

Research Gaps and Priorities

The TBICoE research portfolio meets DOD TBI clinical and operational research needs by aligning to TBI knowledge gaps. Every two years, TBICoE’s Research Section reviews, analyzes, and updates a data-driven, actionable list of research gaps and priorities.

Studies can contribute to multiple gaps and priorities. Primary alignment of a study occurs when most of the findings addresses a specific gap. Secondary alignment occurs when a smaller portion of the findings address a gap. 

2023 TBICoE Publications Catalog

The annual TBICoE Publications Catalog provides an overview of TBICoE's published work. Since 1992, TBICoE has published over 700 peer reviewed manuscripts in collaboration with other institutions. The work aligns and responds to trends, gaps, and priorities of the DHA and broader DOD to inform policy, resource management, and state of the science for warfighters, veterans, their families and caregivers, and health care providers.

The purpose of the catalog is to:

  • Summarize key findings and potential clinical implications of calendar year 2023 TBICoE publications
  • Increase awareness of TBICoE research and surveillance initiatives
  • Assist in the planning of future brain health efforts

This catalog is organized by category or primary topic and contains publication citations, abstracts, and summaries of the potential clinical impact.

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.

This research review describes how pain symptoms can interact with other TBI symptoms, such as sleep disturbances, to impact overall quality of life and TBI recovery. The clinical pearls summarize considerations for evaluating and treating chronic pain in individuals with TBI.

This research review describes how excessive drinking can impact service members with TBI. It lists the effects and risk factors of excessive drinking after TBI and provides resources for providers helping patients manage alcohol consumption. The fact sheet is intended to help providers educate patients about alcohol misuse and TBI.

This research review is a detailed summary of clinical research on coexisting mild TBI and PTSD. 

The research review informs the clinical pearls. It is brief with key action items providers can use when treating service members with both mild TBI and PTSD.

People with a history of TBI may be at increased risk of:

  • Another TBI when exposed to less force.
  • Longer recovery from symptoms of that additional TBI. 

Contact sports and military service add risk for more than one TBI. 

Get key action items and a military clinician’s point of view in the clinical pearls.

This research review is a summary of available clinical research on suicide and TBI. It covers:

  • Prevalence
  • Risk factors
  • Evaluation and screening tools
  • Protective factors and treatment

The TBI and suicide clinical pearls provide key actionable items to providers to screen, identify, and treat service members with TBI for suicide risk. 

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.

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 three of the more common neurodegenerative diseases, Alzheimer’s Disease, Parkinson’s Disease, and Amyotrophic Lateral Sclerosis.

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. Researchers and clinicians can learn about current tools used to measure ANS and their current clinical utility at this time.

TBICoE Congressional Reporting

Some research activity is directed by Congress by National Defense Authorization Acts. That work and the results are reported to Congress. Those reports are part of the public record.

NDAA FY07 Section 721 Report to Congress: Longitudinal Study on Traumatic Brain Injury Incurred by Members of the Armed Forces in OIF/OEF

This study looks at the health effects related to TBI incurred by members of the Armed Forces in OIF/OEF and their families. The final report will be released in 2025.

NDAA FY18 Section 734 Report to Congress: Longitudinal Medical Study on Blast Pressure Exposure of Members of the Armed Forces

The Section 734 Program includes of the following mandates: NDAA FY18 Section 734, NDAA FY19 Section 253, NDAA FY20 Section 717, and NDAA FY20 Section 742.

NDAA FY19 Report to Congress: Chronic Traumatic Encephalopathy

A study and report on chronic traumatic encephalopathy research in the military.

NDAA FY20 Section 750 Report to Congress: Study and Report on Traumatic Brain Injury Mitigation Efforts

This study assessed 30 unique TBI treatments and summarized the findings.
