My son was diagnosed with high functioning autism when he was 4. We worked with diet and biomedical interventions and made moderate progress for a few years. An early ATEC score (after implementing the GAPS diet) was 39. (ATEC scores are a free online survey parents fill out to assess the severity of their child's autism).
When my son turned six, we began implementing Kerri Rivera's protocol for healing autism, which relies heavily on hourly dosing of CD/MMS (CD=Chlorine Dioxide) throughout the entire protocol.
(Kerri Rivera's protocol is outlined in her book "Healing the Symptoms Known as Autism - and available on Amazon.com she references Jim Humble directly in her book and other work and his amazing MMS. You can also see her speak on youtube.com and autismone.com's videos. The protocol suggests a few more things in addition to CD/MMS such as a GF/CF/SF/SF diet and some anti-parasitic supplements.)
Although my son had no apparent "gut health" issues as a co-morbidity of his autism, he began regularly passing parasites in his nightly CD enema (as did I and other members of the family who were also on the protocol).
Within one year of following this protocol, my son's ATEC score was below a 10 (which is considered to be recovered and no longer "diagnosable" with autism). He was recovery #145 on Kerri's list and although he still struggles with a few compulsive tendencies and is catching up on social skills; we plan to continue with CD to address these issues. He was able to matriculate into mainstream Kindergarten and First Grade at the local public school and blend in well with other students. His ABA therapists used to meet with him 3x per week to do drills, and now have stopped seeing him and only meet with me 2x per month to check in... They say he doesn't need their help any more, he just needs to practice being around other kids. He made his first real friends in first grade and according to his teacher was well-liked by his classmates. He passed the safety swim test to go down the water slides at the YMCA, joined Cub Scouts, played T-ball, and was in a play, he went up and comforted a friend who got hurt at camp this week, he held a baby cousin on his lap the first time he met her (3 month old) at his request. He is well-behaved, engaged, loving and calm - all thanks to CD.
I am a huge fan of Jim Humble's work and the results that our family has seen from MMS/CD.
I would encourage others who are considering how best to help a child recover from autism to use CD as a first step. Don't be afraid - try it yourself along side your child. Start slowly. Use sweet leaf stevia to sweeten/flavor it without breaking your child's healthy diet, or negatively impacting the efficacy of CD. This one substance works better than any of the supplements or IV's we spent hundreds (thousands?) of dollars on at the NaturoPath's.
It is very affordable, very inoffensive to take, and very effective. Start low and slow to minimize the herxing and keep your child happy with the doses. It really, really works!
