autism is a symptom of too much stress be it physical/emotional/mental
autism comes from a buildup of stress in the neocortex. there appears to be a maximum-stress tolerance for the brain. if the tolerance is above maximum the child can become autistic.
emotional trauma's in the starting years of a childs life can attribute to autism as well as ofcourse vaccinations. improper food/medication/antibiotics not enough vitamin C, plastics and heavy metals. lets not forget structural integrity. impaired skull-plate mobility seems to attritube to autism as well. a knowledgable chiro can fix this, though we only have one in the netherlands that can. a good osteopath should be able to do it as well
certain child diseases can be the last straw in triggering autism as well like chickenpox. not that chickenpox by itself causes autism but if the stress (as emphasized any type of too much stress, physical as well) has been build up to a maximum it can be the final blow
its an 'and and' story not a single thing most of the time
