I have heard that some people can recover almost totally from Anoxic brain injury and I want to know the process they went through and the rehab as well.

My son, age 30, suffered an anoxic brain injury 5 months ago and he was given a very poor prognosis as is the case with this injury. I am wanting to find out how and where and what type of treatment has worked for those lucky people who recover with little impairment
