Etiology of Autism

Abstract

The causative factor for autism now appears to be a deficient supply of insulin-like growth factor-1 (IGF1 ) and vitamin D3 in many newborn and infants, thereby leading to persistently insufficient myelin in developing cranial nerves. Various malformed neurologic networks last into adulthood. Of particular concern is a pregnancy exposed to febrile viral conditions, where interleukins suppress IGF1 production. Breastfeeding of the newborn may be preventative in many such cases.
