Seizures and epilepsy are common medical disorders that affect children with autism spectrum disorder. Individuals with ASD have a 3 to 22-fold increase in the risk of developing epilepsy as compared to the typical population. The relationship between epilepsy, seizures and ASD is complex, and there is a dearth of information regarding the treatment of individuals with ASD and seizures. This research will fund the implementation and analysis of a parent-friendly online survey for parents of children with ASD, both with and without seizures. The survey is comprehensive and includes questions on seizure characteristics, co-occurring medical conditions, changes in seizures that occur with seasons and allergy flares, and most importantly; the efficacy, effects on behavior and cognition, and side effects of traditional and non-traditional treatments. Local and national autism support groups will be contacted to ask them to advertise the survey and to assist with organization and analysis of the collected data. Responses will be broken down into subgroups in order to study the relationship between ASD and seizures in detail.
