WTC Responders Show Accelerated Brain Aging
Researchers from the Icahn School of Medicine at Mount Sinai report in Translational Psychiatry that World Trade Center responders with PTSD exhibit accelerated brain aging compared with matched non‑PTSD responders, using BrainAgeNeXt trained on over 11,000 MRI scans. In a sample of WTC-PTSD (n=47) and non-PTSD (n=52), brain age differences averaged 3.07 versus −0.43 years (p<0.001), suggesting brain age could monitor trauma-related neurobiological aging and dementia risk.
Key Points
- 1Show accelerated aging: WTC responders with PTSD showed brain age difference averaging 3.07 years versus −0.43 years
- 2Link PTSD to neurobiological aging, indicating trauma can produce measurable structural brain changes
- 3Recommend brain age measurement with BrainAgeNeXt as a biomarker to monitor and guide early interventions
Scoring Rationale
Peer-reviewed, novel application of deep-learning brain age to trauma cohort; limited sample size and requires external replication.
