Has anyone gone this route? Did it provide some insight into your difficult child's diagnosis? My difficult child has been diagnosis's ADHD & EOBD. None of the medication regimes have worked. He just started a therapeutic school program and intensive in home services. All the new eyes are thinking Pervasive Developmental Disorder (PDD)/high functioning autism is a distinct possibility. They are advocating a new neuropsychologist evaluation for this. One of the many, many books I have (don't we all) suggests doing a heavy metal tox screen and screen for food allergies. I have had him tested for environmental allergies a few years ago and those were neg. I have suspicions of food allergies though. Has any one done this, what were your findings and how did you approach it? Did you persue bloodwork through a gp, naturopath or other specialist? Has anyone found that attacking it naturopathically gave them more help vs. traditional medicine? Just trying to decide which route to take this testing and hoping I may find some answers or reasoning as to what is up with difficult child. Thanks!
