I am sorry to hear about your son's condition. Find a good doctor. Keep plugging away....be your own doctor...I just learned that my 77 year old mom has hyrdrocephalus. She had hip surgery five years ago and we thought that was her problem all along. After going to several docs they finally found out her condition. Her symptoms are problems with her gait, memory loss and incontinence. I found several sites on the subject which were very helpful. Mom goes for surgery on Tuesday. Good luck to you.
