What in the world are you talking about?

There are 0 requirements for head trauma with PTSD, it's a stress response.

Cognitive Behavioral Therapy is the top tier, evidence based treatment for PTSD. 60-80% can actually lose their PTSD diagnosis through CBT in some studies.

I'm not saying CBT is the magic cure, but it's very helpful for retraining the body's fight or flight response.

For TBI, there is not really any amount of CBT that can impact it due to the physical changes in the brain. This is why things like ibogaine and psilocybin are encouraging, because they seem to be causing neurogenesis.

I'm somebody that has spent my life dealing with both of these issues through combat sports and military combat. It's something I stay on top of.
