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.

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.

Low-Level Blast: Fact Sheet for DOD Providers

.PDF | 817.46 KB

Low-level blast is defined as blast generated from firing heavy weapon systems or explosives in combat or training environments. Exposure to low-level blast does not typically result in a clinically diagnosable concussion, also known as mild traumatic brain injury. TBICoE developed this fact sheet for DOD health care providers.
