Blasts May Cause Brain Injury Even Without Symptoms
Veterans exposed to explosions who do not report symptoms of traumatic brain injury (TBI) may still have damage to the brain’s white matter comparable to veterans with TBI, according to researchers at Duke Medicine and the U.S. Department of Veterans Affairs.
The findings, published in the Journal of Head Trauma Rehabilitation
, suggest that a lack of clear TBI symptoms following an explosion may not accurately reflect the extent of brain injury.

DTI can detect injury to the brain’s white matter by measuring the flow of fluid in the brain. In healthy white matter, fluid moves in a directional manner, suggesting that the white matter fibers are intact. Injured fibers allow the fluid to diffuse. This illustrative image shows a DTI of the white matter structure in the human brain. The image is not connected to the research. Credit Kubicki et al. #tbi #neurology #braininjury
