<<Disclaimer: Verify this information before applying it to your situation.>> HI! I want to thank everybody who responsed to my question about neurological/behavioral consequences of untreated celiac disease. I received 24 responses in all. Here is the summary: Many had no "Scientific Proof" of behavioral changes with the ingestion of gluten but knew it had happened to them or their celiac children. Two said their children showed no change in ADHD problems even though those children had been gluten free for a substantial period of time. One of those two was now investigating the possibility of also going casein free (dairy free?) with the child to see the effect. Several people pointed out web sites where I might find more information about CD and behavior: WWW.celiac.com & www.panix.com/~donwiss> A couple of people mentioned Lisa Lewis's article--which has to do with Autism and CD. (I believe it can be found on www.panix.com) Some of her suggestions on diet (specifically casein free diets) could also apply to children with other behavior problems. One person recommended books(& authors)--Allergies and Your Family by Dr. Doris Rapp. And Carl Pfeiffer's Mental and Elemental Nutrients. One person summarized articles from several sources including Gut and the Scandinavian Journal of Gastroenterology. I will send this list to anyone who wants it, but it is too long to summarize here. It did make it clear why my son's pediatrician and psychiatrist didn't know this stuff. It's all in gastroenterology journals. This same person explained that untreated celiac disease disrupts neuro-transmitters in the brain because so much serotonin is used in the gut that the brain becomes deficient. This explained a lot to me right there. Two people wrote to tell me that they were pursuing (had pursued) degrees and were researching the behavioral connection with CD. One promised a paper. YES! Thanks to all for your help and support. I finally feel that I have enough "proof." to submit to my son's doctors so they will at least consider it.. Celiac disease does have a behavioral connection--it isn's just in this Mom's head. Christine in Colorado
