The Science of Trauma's Toll
PTSD isn't just psychological - it leaves lasting biological marks that accelerate aging across every system in your body.
Chronic Stress Response
PTSD keeps the body in a constant state of high alert, with elevated cortisol and inflammatory markers that accelerate cellular aging.
DNA Methylation Changes
Trauma literally changes how your genes are expressed. These epigenetic modifications are measurable and contribute to accelerated biological aging.
Multi-System Impact
GrimAge captures accelerated aging across cardiovascular, immune, and metabolic systems - all affected by chronic PTSD.
Why GrimAge for PTSD?
Traditional assessments miss the biological cost of PTSD. GrimAge provides an objective, quantifiable measure of trauma's physical toll.
Objective Biomarker
Unlike questionnaires, GrimAge provides a biological measurement that can't be influenced by self-report bias
Validate Your Experience
Show skeptics that PTSD has real, measurable biological consequences
Track Treatment Progress
Studies show effective PTSD treatment correlates with biological age reduction
Support Claims
Objective evidence of biological impact may support disability documentation

Frequently Asked Questions
How much does PTSD accelerate aging?
Studies show PTSD can accelerate biological aging by 2-15 years, with combat-related PTSD often showing the most pronounced effects. GrimAge specifically is elevated by 4-8 years on average in veterans with PTSD.
Can PTSD treatment reduce biological age?
Emerging research suggests yes. Studies show that effective PTSD treatments (therapy, medication, lifestyle interventions) correlate with improvements in epigenetic aging markers. This is one reason tracking biological age during treatment is valuable.
Do I need a formal PTSD diagnosis to participate?
No. We accept participants with significant trauma exposure who may not have a formal diagnosis. Many veterans avoid diagnosis due to stigma but still experience accelerated aging from their service.
Can this help with VA disability claims?
While GrimAge results are not currently part of standard VA evaluations, objective biological evidence of trauma's impact may support claims. We provide full documentation of results that can be shared with your healthcare providers.
Is this study free for veterans?
We offer subsidized and scholarship pricing for veterans. Thanks to research grants and donor support, many veterans can participate at no or reduced cost. Contact us about veteran pricing options.
