I am hoping to get feedback regarding which direction I should persue? Some back ground: Ggf has been diagnosis'd ADHD and Bipolar. Stims do not work with him at all. He just started a therapeutic school where they in conjunction with our in home services see possible Pervasive Developmental Disorder (PDD)/high functioning autism. At psychiatrist meeting psychiatrist says there is no way difficult child is on the spectrum (I posted this in another thread where I got a lot of great feedback). He also wanted difficult child to try the Daytrana patch (doesn't help, doesn't work). In home services will be pushing for a 2nd neuropsychologist evaluation. My question is where do I go with this? What specialists should I be making appointment's with? Should I be looking for a developmental pediatrician, a pediatric psychologist or another psychiatrist? Should I wait until after another neuropsychologist evaluation - can it be picked up/ruled out there? For the first time in the 3 yrs since we began all this testing and dr's and etc. I don't know where I should go. I contacted a highly respected clinic today and they want $5500 to do an evaluation. They don't take insurance and I don't have that sitting around right now. Thanks!
