Understanding Autism: A Biochemical Approach?

Autism, a complex developmental disability, is generally believed to be a genetic disorder. But Dr. William Walsh, a senior scientist at the Pfeiffer Institute, believes he has isolated a biochemical cause, based on analysis of blood, urine, and hair samples from 503 autistic children. His pioneering research attributes autism to the inability of a protein?metallothionein?to balance the body's metal metabolism. In this program, Dr. Walsh discusses his controversial findings bolstered by parents whose children have shown dramatic results from dietary supplements that counteract metal imbalance
