    Patients with PTSD exhibit molecular changes in redox metabolism, neuronal signaling, and immune activation linked to accelerated biological aging.

  • 2

    The study analyzed plasma samples from 393 World Trade Center responders, including 232 with PTSD and 161 trauma-exposed controls.

  • 3

    Researchers identified 121 significantly altered protein analytes and seven differentially expressed metabolites associated with PTSD.

  • 4

    Accelerated biological aging was observed in PTSD patients, with altered proteomic aging signatures in the pancreas and lungs.

  • 5

    The study's cross-sectional design limits conclusions about causality, and findings may not generalize beyond the studied population.
