rena,

Welcome to NeuroTalk. I am sorry to hear your son is struggling. There is no way to directly connect his current symptoms to his past injury without some very specialized testing. I don't see the value in making this determination.

The issue is, How do you and your son go forward?

The books you mention sound like they are worthwhile. The solutions require the efforts of both the injured and those around the injured. Understanding the injury allows all to work with the limitations rather than fight against them.

What have doctors said about your son's condition? Has his CSF pressure been tested? Does he breath properly when he sleeps?

What diagnostics has he undergone?

btw, How old is he now?

My best to you.
