Defeat Autism Now (DAN) is a project of the Autism Research Institute, founded in the 1960’s by Dr. Bernard Rimland. DAN! Doctors are trained in an approach to autism treatment that begins with the idea that autism is a biomedical disorder caused by a combination of lowered immune response, external toxins from vaccines and other sources, and problems caused by certain foods. DAN doctors may recommend treatments including nutritional supplements, special diets, testing for hidden food allergies, treatment of intestinal yeast or bacterial overgrowth, and detoxification of heavy metals. DAN doctors are medical doctors who attend DAN training programs.
