Can a Brain Injury Case PTSD?

Can a Brain Injury Case PTSD?

A study conducted by UCLA life scientists, and found in the academic journal Biological Psychiatry, reveals a causal link between traumatic brain injury (TBI) and an increased vulnerability to post-traumatic stress disorder (PTSD). It also suggests that those who suffer from brain injuries should take precautions to avoid stressful situations which could exacerbate their health condition.

The study itself was inspired by an observed connection between TBI and PTSD, specifically in military veterans who have returned from campaigns in Afghanistan and Iraq. The question the scientists asked was whether the events which resulted in the initial brain injury were traumatic enough to cause PTSD, of it the disorders could be linked in a “more mechanistic way.”

Scientists conducted various procedures on rats to test the hypothesis, separating their physical and emotional traumas. The scientists used fear conditioning techniques two days after the rats experienced concussive brain traumas. In conclusion, the rats who had suffered TBIs were more prone to fear than those rats who had not received prior injuries.

In order to examine the reason for this, researchers analyzed a small piece of brain tissue known as the “amygdala,” which is the part of the brain where fear is learned. There are substantially more receptors for excitatory neurotransmitters which promote learning in the part of the brain. The findings suggest that TBIs leave the amygdala in a more vulnerable state to acquire fear.

The research was funded by the U.S. Department of Defense and the UCLA Brain Injury Center.
