Description:

Objective:

This project addresses three major hypotheses:

  1. The regression of neurological function observed in some children with autistic spectrum disorder, which occurs at the time the child becomes mobile, is a result of exposure to high levels of neurotoxicants.

  2. In children with autistic spectrum disorder, high levels of neurotoxicants can altar regional brain growth patterns as determined by magnetic resonance imaging (MRI).

  3. Susceptibility to developing autism can be influenced by the child or mother’s genotype of enzymes involved in protecting the developing human from chemical-induced oxidative stress.

The specific objectives of the research project are to: (1) compare and contrast the pattern of exposure to environmental chemicals of children with autism and determine if the pattern is different than that observed in children without autism, including documenting carefully mouthing behaviors (frequency and duration of time objects are in the child’s mouth), exploring their environment, and time on the floor; (2) identify if children with autism have altered body burdens of environmental chemicals as compared to children without autism; (3) determine if children with autism who experience regression or loss of neurological function as compared to children without autism that do not experience regression of function have behaviors that potentially expose the children to higher levels of environmental chemicals and/or have higher body burdens of environmental chemicals; (4) determine if children with autism have specific genetic predisposition to chemical-induced toxic effects; (5) determine if children with autism who experience regression of function have specific pattern of brain development as determined by MRI or have specific genetic susceptibility to chemicals induced biologic effects; and (6) determine if the specific recommendation to the parents regarding home environment or altering the child’s exposure to environmental chemicals, such as hand washing and so forth, can reduce significantly the exposure and body burdens of environmental chemicals in these children.
