In this compelling episode of Broken Brains with Bruce Parkman, we’re joined by former U.S. Army Green Beret and co-founder of Revival Hyperbarics, Wren Murray, for a powerful discussion on traumatic brain injury (TBI), PTSD, and the groundbreaking role of hyperbaric oxygen therapy (HBOT) in veteran recovery.

Wren shares his deeply personal experience with repetitive brain trauma from combat and training, and how HBOT changed the trajectory of his life. He unpacks the science behind neuroinflammation, the hurdles of getting alternative treatments recognized in traditional medicine, and the urgent need for policy change to expand access to HBOT for those who need it most—veterans, first responders, and athletes.

If you or someone you love is affected by TBI or PTSD, this episode offers hope, science-backed insights, and a call to rethink how we approach healing from the invisible wounds of war.
