Traumatic Brain Injury from Blasts Possible Without Symptoms

A new study led by Rajendra Morey, MD, Associate Professor at the Duke University Brain Imaging and Analysis Center,  Duke Psychiatry and Behavioral Sciences, found that veterans who were exposed to blasts during deployment but are not showing signs of traumatic brain injury (TBI) could still suffer long-term neurological damage.  TBI is typically diagnosed by assessing signs of affective dysfunction such as, losing consciousness, blurred vision, and headaches.  Dr. Morey’s found that even in the absence of these symptoms the white matter, the connective wiring that links different areas of the brain, may still be affected.  

In an article from Fox News, Dr. Morey is quoted saying, “The idea would be that people who have had blast exposure should be aware that if they’re experiencing chronic symptoms – like depression, irritability or fatigue – [veterans] and doctors should be aware it could be from blast exposure.  Also doctors should be careful not to diagnose it as other things, such as PTSD or depression.”
