Autism: Affects the Whole Brain

This research makes sense to me. When an autistic child is given an anti-histamine, everything improves. An anti-histamine works system-wide not on just one part of the brain. Also, autistic children always have motor involvement which implicates the brain stem, motor cortex and other various brain areas.

So autism will be cured when the genetic metabolic disorder is solved. At least that's my theory.
