Autism is essentially a more advanced and complicated form of ADHD. Toxic heavy metals are present at higher levels in the midline cerebral canal, and gathered in uneven layers. This helps explain why there’s an autism spectrum, with the syndrome displaying in different intensities depending on the child. It all has to do with the amount of heavy metals in the canal, and in what positions they have accumulated. With autism (versus ADHD), the additional layers of mercury interfere even more greatly with the metaphysical and electrical energy communications trying to cross the canal.
