PTSD May Be Linked to Accelerated Aging

Integrated proteomic and metabolomic analyses identified redox-metabolic signatures associated with chronic posttraumatic stress disorder and accelerated biological aging across multiple organ systems.

    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.
