Study of Children with Autism Spectrum Disorder with and without GI problems

Last Updated: Tuesday, June 11, 2013

Principal Investigator: Jeremy M. Veenstra-VanderWeele, M.D.


Has your child been diagnosed with an autism spectrum disorder?

Does your child have GI troubles, constipation, diarrhea or frequent vomiting?

We are examining the connections between stress, gastrointestinal (GI)/stomach problems, and autism spectrum disorders (ASD).

A previous diagnosis of an ASD is required for participation, although GI/stomach problems are not required.

You will be asked to come for 1 outpatient visit to Vanderbilt University Medical Center in Nashville, TN to take part in this research study. A blood draw and saliva sample are required the visit. Compensation for your time is available.

Participant Criteria

Children age 6-18 with autism spectrum disorders with and without GI problems.
