Traumatic brain injury increases chances to develop PTSD by double-fold: Study
A study based on troops deployed in Iraq and Afghanistan have found that a physical injury to brain make people vulnerable to post-traumatic stress disorder. If service members who were found to have suffered concussion or mild brain injury, they were more likely to develop PTSD, said the researchers on the basis of the studies of troops.
The research paper published in JAMA Psychiatry has unveiled that troops who have suffered concussion or mild brain injury are twice as likely to develop PTSD. The condition has been linked with different psychological difficulties, including insomnia, chronic depression, eating disorders, anger and substance abuse.
For past many years, scientists have suspected about the link between traumatic brain injury (TBI) and PTSD. But they started to become sure after studying troops coming back from Iraq and Afghanistan. Many service members were found to have developed PTSD after they returned from their deployment in Iraq.
The researchers have studied more than 1,600 Marine and Navy service members from San Diego’s Camp Pendleton. Before they were being deployed to Iraq or Afghanistan, medical checkups were done and then again three months after returning.
Baker said, “At one point we got this battalion that went to Helmand province in Afghanistan, and literally 50 percent of them were complaining of blast exposures and symptoms”. The revelation was concerning for Baker as they came to know that troops having a traumatic brain injury were twice likely to develop post-traumatic stress disorder.
The researchers even mentioned of study carried out on mice. In it, the mice that have experienced a TBI showed greater levels of fear response than it normally would be. Baker said that brain injuries do bring changes in the brain’s fear circuitry.
