New research from Stony Brook Medicine’s World Trade Center Health and Wellness Program has identified abnormalities in brain composition among 9/11 first responders experiencing post-traumatic stress disorder. The study analyzed MRIs of nearly 100 World Trade Center responders captured between 2016 and 2019, with approximately half diagnosed with PTSD. The research is the first of several studies slated for publication revealing the biological markers and physical impacts of PTSD in first responders.
Brain Imaging Findings
MRIs of responders with PTSD appeared “blurry” compared to healthy brains, according to Sean Clouston, the study’s lead author and a professor at Stony Brook University’s Renaissance School of Medicine. A healthy brain displays clear contrast between gray matter—functioning as a processing unit and hard drive—and white matter, which sends signals throughout the brain and body. Memory-related areas reside “mostly in the gray matter.” The loss of gray-white contrast in PTSD-affected brains “could help to explain why [traumatic memories] are more severe, harder to control” and manifest as “flashbacks and nightmares,” Clouston said. The most significant brain composition changes appeared in responders who re-experienced PTSD symptoms compared to those whose PTSD materialized as depression or those with no PTSD diagnosis, suggesting “different clusters of PTSD.”
Implications for Treatment and Compensation
Dr. Benjamin Luft, director of Stony Brook’s 9/11 program, hopes biological evidence will persuade lawmakers to update the James Zadroga 9/11 Health and Compensation Act. Approximately 23% of World Trade Center responders diagnosed with PTSD currently cannot receive compensation through the September 11th Victim Compensation Fund. Luft stated this sends “a very strong symbolic message” excluding PTSD as a “real injury.” About 80% of more than 6,000 first responders surveyed reported stigma remains “somewhat of a barrier” to seeking services. Retired NYPD Detective Glen Klein, diagnosed with chronic PTSD, believes physical evidence may encourage reluctant individuals to seek help: “Once they know it’s a physical injury … they’re going to come out and say, ‘Oh … I don’t have to deny it anymore.’” Clouston noted that different biological presentations of PTSD could lead to optimized treatments tailored to individuals.
