For those using HBOT for brain injury, when did you start noticing a shift in the "cognitive fatigue"?

I’m currently navigating the long road of recovery from a TBI (old concussion that never quite felt fully healed). I’ve made a lot of progress with standard rest and PT, but I’ve hit a bit of a plateau when it comes to the mental stamina and that "heavy" feeling in my head by the end of the day.

I’ve been reading up on how increasing oxygen under pressure can potentially help with neuroplasticity and getting blood flow back into areas that were affected by the impact. It’s a fascinating area of research, but I’m curious about the real-world timeline.

If you’re using a chamber for brain injury recovery, did you find that it helped more with the physical symptoms (like headaches) or the cognitive side (like focus and memory)? And how many sessions in were you before things started to "click"?

I found a really thorough breakdown of the science behind how hyperbaric therapy supports TBI recovery specifically—it helped me understand the biological side of why the pressure matters for brain tissue. Sharing it here for anyone else doing their homework:
