Welcome to SEED II

SEED stands for the Study to Explore Early Development. SEED is the largest epidemiological study to-date designed to compare children with autism and other developmental delays to children without these delays. The first phase of this study (SEED I) began in 2006 and the second phase (SEED II) began in 2012. Results from SEED will help researchers to better understand the health and behavior of young children with autism and to identify factors that contribute to autism.

SEED is funded by the Centers for Disease Control and Prevention (CDC) as part of the Centers for Autism and Developmental Disabilities Research and Epidemiology Network (CADDRE).

We are currently seeking families from central North Carolina to participate in SEED II. You can learn if your family might be eligible by browsing this website and completing the Interest Form (click Interest Form button on this page) or you may contact us by phone, fax or email.
