PTSD's Physical Mark Found in 9/11 Responders
20 Dec
Summary
- New study reveals physical evidence of PTSD in World Trade Center first responders.
- Researchers observed distinct differences in brain matter structure for those with PTSD.
- Study findings may reshape the understanding and diagnosis of post-traumatic stress disorder.
Researchers at Stony Brook Medicine have uncovered compelling physical evidence of post-traumatic stress disorder (PTSD) among World Trade Center first responders. This study marks a significant advancement, as PTSD has historically been diagnosed primarily through observed symptoms rather than scientific indicators. The research indicates that PTSD leaves lasting structural changes within the brain.
Lead author Sean Clouston noted that individuals with PTSD exhibited lighter gray matter, appearing more like white matter. This structural alteration suggests disruptions in how the brain processes and controls traumatic memories, potentially explaining persistent symptoms like flashbacks and re-experiencing trauma. The study scanned 99 first responders, building on over two decades of dedicated research into their well-being.
