Chronic exposure to low levels of blast may be associated with neurotrauma

WRAIR scientists demonstrated that TBI biomarkers were elevated among law enforcement and military personnel, including those without a diagnosed brain injury or concussion, repeatedly exposed to low level blast. Repeated exposure have been linked to a series of reported symptoms such as headaches, fatigue, dizziness, memory difficulties, and tinnitus. Researchers hope these data are the first step to identifying objective biomarkers as clinically relevant diagnostic tools.
