Hi, I am also new to the forum and I work as a nurse practitioner. I have experience managing chelation for children on the spectrum.
Chelation has its risks, but so does retaining toxins in the body tissues. Spectrum children often have difficulties detoxifying, and end up holding on to toxic substances (pesticides, mercury, arsenic, etc) in their tissues, many of which mimic hormones, are cancer-causing, and are neurotoxic. Ideally, you would detoxify until the toxins were no longer detectable - this may take a few months to a few years of consistent chelation depending on the person/child.
Reducing (and eliminating where possbile) exposure to these toxins in the every-day environment is a must.
The good thing about CAEDTA is that it also binds to mercury - although not as effectively as DMPS. Kidney and liver function tests should be done routinely to detect the start of any organ compromise. Mineral levels also need to be monitored and replaced while chelation is ongoing.
Hope this helps!
My best to you and your son.
