Do children with Pervasive Developmental Disorder, Asperger's Syndrome, Apraxia, Dyspraxia and Sensory Integration Dysfunction, and Expressive/Receptive Language Disorder respond to this diet? These are all considered by many to be disorders on the autism spectrum. If you took the same autistic child to six different doctors, he could be diagnosed with each of the above. For some reason, many professionals are reluctant to use the "Autism" label, perhaps because they want to "spare" the family. We have heard from many, many parents who have told us that some of their children with these diagnoses responded dramatically to the diet. Remember, this diet will only improve the symptoms in children whose behaviors are being caused by the abnormal breakdown of these proteins. This is not the case with every child, but a significant number do respond.
