Diet is the whole key to recovery because they have to grow new brain cells (damaged to varying degrees by various things in vaccines, like toxins from bacteria causing necrosis of budding dendrites). Brain cells can keep growing in the Higher Brain (with protein, balanced, non-toxic diet), but NOT in the Old Brain. The Old Brain at the base,  location of all Behavioral Instincts, and Chemical Regulation for the body, including the Gastro-Intestinal Tract, releasing the chemicals needed for break-down and digestion. Thus, these kids problems are compounded by difficulty digesting (absorbing nutrients). Digestable high protein diets will give the building blocks in the form of Amino Acids to make new brain cells. The peculiarity of Autism is from Developmental Damage in the Old Brain - depending on the severity of brain cell damage, recovery occurs everywhere , but in this area (being the foundation). BUT recovery cannot be ruled out, and anything is possible. But therein, within the unknown region of the Old Brain, lies the dilemma. Higher brain recovery can become great enough to raise geniuses whom can learn to understand what they lack instinctually. Using their highly developed conscious minds (Higher Brains), they can teach themselves how to behave properly, becoming Consious of what is missing, thus learning to teach natural behaviors to themselves cognitively. (by the way, each vaccine dose is suspended in vials of heavy metals, so Thimerasol did not need to be replaced by anything). I give talks with drawings on chalkboards for visual comprehension; about germs, vaccine recipes, and infant physiology. I have a booklet about how vaccines cause Autism, and the site http://www.trackingvaccinations.com (Tracking Vaccinations).
