My husband was having severe headaches before surgery, all this other stuff is new since surgery. What symptoms is your husband having other than the confusion? Does he now have hydrocephalus from the Encephalomalacia? I read up on that was not familiar with it. It is softening of the brain tissue right? Have you gotten a second opinion? It may put your mind at ease. Unfortunatly my husband didn't have a choice the fluid was making his ventricles so large it was putting pressure on the brain. He really suffered with headaches the week before his surgery. It was real bad! so his symptoms were relieved for about 2 month, then all this started slowly and eventualy getting worse. We see neurologist Tuesday.
Some people have no problems with their shunt at all. Good Luck. I know its a hard decision to make.
