There's major uproar recently in the "epidemic" the United States is having with our children getting autism or Asperger Syndrome. Lots of folks are convinced it's caused by mercury, especially from the vaccinations we've had to give our kids, and other toxins we've been exposed to. If you take that knowledge to your husband, maybe he'd be more willing to try detoxing for mercury and the heavy metals, and might then be willing to at least give oil pulling, Iodine or some other therapy a try.
