Kyle and Joshua have been invited to participate in a study on the causes of Autism at Stanford University in California. About 1 in 88 children have been identified as having an autism spectrum disorder (asd). Kyle and Joshua are twins. Kyle does not have Autism but Joshua does. By participating in this study the researchers hope to find out what differences these two have in terms of their brain development and why one has Autism and the other doesn't. The researchers will cover some expenses for the trip but the rest of our children would like to come to support them. We hope to provide valuable information in finding a cause and perhaps a cure for Autism. We would appreciate your support! Thanks!
