Is mercury exposure a contributor to ASD?
Autism Society of America: Environmental Health Frequently A...The role of mercury as a risk factor for childhood autism is not fully understood; however, it has been shown that mercury can interfere with the signaling pathways in a child’s developing brain and the modulation of proteins that regulate the immune system (see Understanding Mercury, Understanding Autism by Ellen Silbergeld, Ph.D., and Jennifer Nyland, Ph.D.).
Related QuestionsWhat is the relationship between environmental toxins and ASD?
Autism Society of America: Environmental Health Frequently A...Findings indicate that many children with autism or those who are at risk of developing autism have a metabolic impairment that reduces their ability to rid their bodies of heavy metals and other toxins. Build-up of these toxins in the body can lead to brain and nervous system damage and developmental delays (see We’re Loaded with Toxins: Analyzing the Toxic Body Burden of Americans by Judy Chinitz Gorman).
Related QuestionsAre pesticides a potential contributor to ASD?
Autism Society of America: Environmental Health Frequently A...Some children who are genetically at risk for ASD may be more susceptible to the adverse effects of pesticide exposure. Research shows that several genes associated with autism risk encode for proteins that regulate excitation/inhibition within the central nervous system. Several of these neurotransmitter systems are known to be targets of pesticides frequently found in children (see Can Exposure to Environmental Toxicants Influence Autism Susceptibility? by Isaac N. Pessah, Ph.D.).
Related QuestionsWhat is autoimmunity and what is its relationship to ASD?
Autism Society of America: Environmental Health Frequently A...Autoimmunity is a condition in which the immune system attacks the body’s own tissues. Several studies show that autoimmune activity can be associated with ASD in some cases, but it has not been determined if this activity contributes to the development of the disorder or if it is a consequence of the disease (see Autism Spectrum Disorders and the Immune System by Paula Goines, B.S., Paul Ashwood, Ph.D., and Judy Van de Water, Ph.D.).
Related QuestionsHave some children with autism recovered from ASD?
Autism Society of America: Environmental Health Frequently A...There are reported cases that some children with autism have substantially or completely recovered. Commonweal, a non-profit health and environmental research institute, is conducting an autism recovery documentation project that will provide a detailed report of a number of verifiable recoveries from ASD (see Helping to Shift the Paradigm: Learning More About Recovery in Autism by Robert Sinaiko).

Dr. Gertrude A. Barber National Institute - FAQs about Autis...Conclusions: All participants in most studies had problems associated with the symptoms of autism that persisted into adulthood. While continued research is needed to more carefully define what aspects of autistic symptoms most severely affect outcome, many studies do show that IQ over 70 has some effect.
