A new study suggests that post-traumatic stress disorder patients who also suffer from an underlying traumatic brain injury may have more difficulty recovering from post-traumatic stress symptoms. The research could impact future treatments for PTSD patients in Arizona and nationwide.
Medical professionals have long understood that individuals with either PTSD or TBI experience high rates of disability and suicide. The conditions are also known to frequently co-occur. In order to better understand which brain networks are disturbed by these disorders, researchers used a sophisticated MRI analysis technique known as graph theory to examine the brain networks of 208 military veterans who experienced a traumatic event. The technique allows scientists to observe brain connections at a new level of complexity.
