Low-Level Blast Exposure and TBI

Health care providers across the DOD and the VA and service members should be aware of the potential effects of low-level blast exposure and which occupations and heavy weapon systems are associated with increased risk of LLB exposure. Research is still emerging on the full impact of LLB exposure on brain health and performance outcomes.

What Is Low-Level Blast?

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/mild traumatic brain injury. Exposure does not equal injury!

Providers

Does your patient work with heavy weapons systems, explosives, or both, and complain of: 

  • Concentration problems
  • Difficulty hearing
  • Headaches
  • Memory problems
  • Slowed thinking or reaction times
  • Decreased hand-eye coordination

They could be experiencing symptoms from low-level blast exposure. Download our new fact sheet and learn how to best document, manage, and care for your patients—to optimize warfighter brain health.

Service Members

Does your military occupation involve working with heavy weapon systems that leave you feeling unwell or not like yourself? You could be experiencing the effects from low-level blast exposure.

Symptoms from low-level blast exposure usually resolve with time. Learn more about how you can recognize, limit, and report your low-level blast exposure with our new fact sheet.

What is TBICoE Doing to Learn More About LLB?

We've designed an infographic to help illustrate some of the research work being done to better understand how low-level blast influences warfighter brain health. These efforts directly support Line of Effort 2 of the Warfighter Brain Health Initiative.

What is TBICoE doing to help warfighters exposed to low-level blast? Leading the charge: 1. Collaborated on Military weapons training studies and Epidemiology studies 2. Led health and performance efforts in support of the Section 734 Program Advancing the science: 1. Measured LLB exposure effects on performance 2. Provided recommendations on LLB surveillance 3. Advanced DOD’s understanding of LLB health and performance effects Answering the call: 1. Outlined next steps for LLB research 2. Helped to develop guidance for managing brain health risk from blast overexposure 3. Recommended the development of a tool to capture career blast exposure These efforts are in support of the Warfighter Brain Health Initiative LLB Relevant Aims 1. Understand the known and emerging threats and hazards to brain health 2. Monitor warfighters for brain exposures 3. Reduce risk of brain exposures that may negatively impact brain health
