Gastrointestinal Symptoms in ASD Children: The Chicken, or the Egg?

This talk will focus on our work designed to characterize, both clinically and at a deeper molecular level, gastrointestinal symptoms in ASD children as compared to typically developing children. Our studies are geared towards gaining a more complete understanding of the complex biologic mechanisms that underlie these symptoms in children with ASD so that effective treatment strategies can be implemented early.

Two of the key difficulties in diagnosing and treating autism spectrum disorders are: (1) a lack of biological/molecular criteria to aid in diagnosis and, (2) a lack of understanding of the biological mechanisms that underlie this complex set of disorders. Dr. Walker’s current research focuses on using molecular tools, including whole-genome microarrays, to better understand the biological basis for autism spectrum disorders and co-morbid medical conditions.
