I recently completed 40 hyperbaric oxygen treatments at 1.5 atmosphere. I did 5 treatments a week (once daily M-F) for 8 weeks. While I am not 100% yet I have made great progress so far.
I have had PCS before about 3 years ago and hit my head again on a counter top about 6 months ago (4 months out when I started therapy). I also have had countless sub concussive impacts from playing ice hockey and snowboarding my entire life. These reasons are why I feel I am not 100% yet. However my cognitive test scores improved DRAMATICALLY. I attached a picture of them.
Anyone who can afford this treatment (8000$ for 40 treatments) without going broke should really consider this treatment. Here is a link to a study with great results with patients being 2+ years out from injury:

In about a month I will be doing 40 more treatments. By the end of that set of treatments I hope to be 100% or close to it.
