Research Insights into the Etiology of Autism - Abstract
A variety of environmental factors affecting the internal biochemical milieu have been found to coexist with autism. Efforts to convincingly demonstrate a cause-and-effect relationship with any of them are explored here. Several have been discarded after extensive research has failed to corroborate a cause-and-effect relationship. Currently, the most plausible appears to be the attenuated role of insulin-like growth factor in promoting myelination of neurons in neonates.
