Traumatic brain injury in modern war

Area of Science:

• Neuroscience
• Military Medicine
• Trauma Surgery

Background:

• Explosive blasts pose a significant threat, causing traumatic brain injury (TBI) through mechanisms like pressure wave coupling.
• Understanding the full spectrum of blast-related injuries, including effects beyond direct pressure, remains an ongoing research area.

Purpose of the Study:

• To review the current body of scientific literature concerning traumatic brain injury (TBI) resulting from explosive blast events.
• To outline the emerging understanding of blast-induced TBI mechanisms, clinical presentations, and management strategies.

Main Methods:

• Literature review of emerging scientific insights into blast TBI.
• Analysis of current military and civilian clinical practice guidelines for TBI management.
• Examination of system-wide approaches to TBI diagnosis and care within military and Veterans' Affairs (VA) systems.

Main Results:

• Detonation pressure waves coupling to the head, causing brain deformation, are a primary mechanism of blast TBI.
• Existing civilian TBI management guidelines are adapted, and new military-specific guidelines (e.g., VA/DoD Clinical Practice Guidelines for Concussion/Mild TBI) are being developed.
• A comprehensive, system-wide approach to TBI diagnosis and management has been established, spanning from the point of injury through military and VA healthcare.

Conclusions:

• Traumatic brain injury from explosive blasts is addressed comprehensively, from fundamental research to clinical application.
• Standardized clinical practice guidelines and a unified system-wide approach are crucial for managing blast-induced TBI effectively.
