Brain Injury to Soldiers Can Arise from Exposure to a Single Explosion

Posted by

ScienceDaily (May 16, 2012) — Investigators from Boston University (BU) and the Veterans Affairs Boston Healthcare System have shown evidence of chronic traumatic encephalopathy (CTE) in brain tissue from blast-exposed military service personnel. Laboratory experiments conducted by the investigators demonstrated that exposure to a single blast equivalent to a typical improvised explosive device (IED) results in CTE and long-term brain impairments that accompany the disease. They also found that the blast wind, not the shock wave, from the IED blast leads to traumatic brain injury (TBI) and long-term consequences, including CTE.

This research, which represents the first case series of postmortem brains from U.S. military personnel who were exposed to a blast and/or a concussive injury, will be published online May 16 by Science Translational Medicine.

Lee Goldstein, MD, PhD, associate professor at Boston University School of Medicine (BUSM) and Boston University College of Engineering, and Ann McKee, MD, professor at BUSM and director of the Neuropathology Service for VA New England Healthcare System, led this international collaborative study and are the senior co-authors.

CTE, which can only be diagnosed postmortem, is a progressive neurodegenerative brain disorder that has been reported in athletes with multiple concussions or subconcussive injuries.
