On the other hand, if your health insurance is through one system and your disability insurance through another, you have everyone optimizing for their personal local minimums rather than the global minimum.
Like most "alternative" medicines this one gets pushed hard as a solution for everything, regardless of evidence.

> As of 2012 there is insufficient evidence to support using hyperbaric oxygen therapy to treat people who have traumatic brain injuries.[51] In stroke, HBOT does not show benefit.[52][45] HBOT in multiple sclerosis has not shown benefit and routine use is not recommended.[44][53]
> A 2007 review of HBOT in cerebral palsy found no difference compared to the control group.[54][55] Neuropsychological tests also showed no difference between HBOT and room air and based on caregiver report, those who received room air had significantly better mobility and social functioning.[54][55] Children receiving HBOT were reported to experience seizures and the need for tympanostomy tubes to equalize ear pressure, though the incidence was not clear.[54]
we wish it were otherwise, but: if your son had a brain injury where cells died, no amount of oxygen is going to bring them back (or even help his recovery).
i'm sorry for your son's circumstances (and yours...). But you are a victim twice when you invest time, energy, money, and hope in these quack therapies (I'm sorry to call them that, because it seems so pejorative, but that's what they are).
i don't know what it is about quack treatments that make us so susceptible to them... I think it's a missing piece of the Kubler Ross model of grief. Just like our parents who fall victims to ridiculous "nigerian prince" or "check cashing" scams when you can't understand how... it's not because they are dumb, or stupid, but because there is some aspect of human psychology (hope? denial? grief? whatever...) that puts us all at risk of fooling ourselves... we become unable to see the truth, because of how powerfully we want to see something else.
i hope this possibility makes sense to you, because your son will benefit a thousand times more from your attention than if you take the same attention and spend it fighting against "the system" (in whatever form it takes). and take comfort in the fact that even though "the system" really sucks in terms of its limitations, that it does, in general, stumble toward progress, and the future will be better than the present.
Until then... cherish your son and enjoy your time with him to the best of your mutual abilities.
