What this trial studies

This observational study aims to evaluate the effects of a combined treatment protocol involving subanesthetic ketamine infusions and bilateral cervical sympathetic blocks on aging markers in Special Operations Forces members diagnosed with PTSD and traumatic brain injury. The primary focus is to measure changes in the GrimAge epigenetic clock, while secondary objectives include assessing improvements in mental health through various standardized questionnaires over a six-month period. Additionally, the study will explore the relationship between PTSD and hormonal changes, specifically testosterone and C-reactive protein levels.

Who should consider this trial

Good fit: Ideal candidates are active duty or retired Special Operations Forces members aged 40 to 60 with a confirmed diagnosis of PTSD.

Not a fit: Patients with conditions such as Horner syndrome or those with a history of severe psychiatric issues may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide insights into innovative treatments that may reverse aging effects and improve mental health in veterans with PTSD and TBI.

How similar studies have performed: While the specific combination of treatments is novel, similar studies have shown promising results in using ketamine for PTSD and mental health improvements.
