Washington University, home to 18 Nobel Laureates, is one of the top rated medical schools in the country. Located in St. Louis’ beautiful Central West End, the campus is adjacent to expansive Forest Park.

Washington University is one of 21 institutions nationwide that will recruit families to participate in the ABCD Study. This ABCD Site will enroll 200 Missouri-born twin pairs (400 twins total) and 200 non-twins from select local school districts. Children will be recruited at age 9 or 10 and will be followed through the teen years. Families in the ABCD Study will complete the majority of their assessments in our research suite in the CID Building (photo, bottom left), in a space specifically designed for children and families. The CID is at 4560 Clayton Avenue, St. Louis MO, 63110. The MRI part of the study will take place in the East Building , a world- renowned research imaging facility (photo, below right). The East Building is at 4525 Scott Avenue, St. Louis MO, 63110.
