Two clinicians who “utilize detoxification methods in their clinical practices” together with a third author have published an epic review in Translational Psychiatry claiming to evaluate the evidence for the involvement of environmental contaminants in autism. While we obviously want to limit contaminant exposure, autism doesn’t emerge here as the reason for doing so. Something that does emerge, however, looks a lot like bias and not much like systematic evaluation.
