This is a condensed literature review of current etiological and treatment findings in autism. Numerous studies examining autistic individuals for a biological marker have been performed with renewed interest over the past several years. Biochemical studies have revealed excessive amounts of serotonin, dopamine and opiods in marry autistics. Reductions in self injurious behaviors, aggressiveness, hyperactivity and stereotypies in patients on medications targeting these specific receptor sites have been documented. Though genetic studies indicate a significant contribution to the transmission of autism, the final common etiological pathway remain unknown.
