Research on Autism Spectrum Disorder

Study to Explore Early Development (SEED)

CDC’s Study to Explore Early Development (SEED) helps us learn more about autism spectrum disorder (ASD) in preschool-aged children. SEED is one of the largest studies of young children, ages 2-5 years, with ASD in the United States. It looks at their risk factors for ASD and developmental characteristics. In 2021, SEED was expanded to learn more about the health, functioning, and needs of people with ASD and other developmental disabilities as they mature.
