<<Disclaimer: Verify this information before applying it to your situation.>> Dear all; I am new to this list service and am interested in reports from other families that have placed their autistic children on the G/F and C/F diets. What changes did you see? What time frames did these changes take place? Our son Brad was diagnosed with PDD at the age of 4 1/2. He is now 6 and for the last 1 1/2 years we have worked with him in a home based program from The Option Institute called "Son-Rise". Brad has made very good progress regarding his eye-contact,communication skills, control over impulsive behaviors, and general overall improvement in all areas. We received information in January '96 regarding research being performed by Dr. Robert Cade at the University of Florida regarding high intolerances of Gluten and Casin in the diets of autistic children. We sent blood and urine samples to be analyzed and found out that Brad's results were extremely high in both catagories. We were instructed to start the G/F and C/F diet immediately. We have been on the diet for about 2 weeks, but have not noticed a lot of difference, except he seems to be a little more hyper at times. I understand there is a withdraw period before noticable changes. Can you provide me details about the characteristics of this withdraw period and how long it lasts, also what noticable improvements your children have made while on the diet. thanks, Kent Davis Charlotte, NC
