The researchers pulled data from 23,743 adults in the Mass General Brigham Biobank, cross-referencing genomic risk scores for PTSD against actual diagnostic histories. The genetic analysis pointed in one direction: PTSD appears to drive changes in these biomarkers, not the other way around , according to findings published in Molecular Psychiatry . Untreated PTSD reshapes cardiometabolic, immune, and liver health, the study suggests — bodily damage that shows up in routine labs long before anyone connects it back to trauma.…
