Research at the Traumatic Brain Injury Center of Excellence

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 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.


TBICoE Research Gaps and Priorities (2022-2024)

The 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 depending on the scope of the aims. Primary alignment of a study to a gap occurs when most of the findings address that specific gap, while secondary alignment occurs when a smaller portion of the findings address the gap. The annual "TBICoE Publications Catalog" provides an overview of TBICoE's published work. The 2023 catalog is coming soon, and the 2022 publications catalog is available now.

Review the gaps and priorities.

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.

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.

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.

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.

TBICoE Publications

Since 1992, TBICoE has published over 700 peer reviewed manuscripts in collaboration with other institutions, which actively align and respond to trends, gaps, and priorities of the DHA or broader DOD to inform policy, resource management, and state of the science for warfighters, veterans, their families and caregivers, and health care providers.

2022 Publications Catalog

The purpose of this catalog is to:

  • Summarize key findings and potential clinical implications of calendar year 2022 TBICoE publications.
  • Increase awareness.
  • Assist in planning of future efforts.

This document contains figures that help visually categorize the publications, as well as citations and abstracts of each (abbreviations in abstracts may be modified for consistency throughout this document). Accompanying the abstracts are the potential clinical impact summaries of the work and the associated TBICoE research network site (including research at TBICoE headquarters).
