The National Institutes of Health announced today that enrollment for the Adolescent Brain Cognitive Development (ABCD) Study is now complete and, in early 2019, scientists will have access to baseline data from all ABCD Study participants.
There are 11,874 youth, ages 9-10, participating in the study, including 2,100 young people who are twins or triplets. All will be followed through young adulthood.
The ABCD Study is a landmark study on brain development and child health that will increase understanding of environmental, social, genetic, and other biological factors that affect brain and cognitive development and can enhance or disrupt a young person’s life trajectory. Coordinated by the National Institute on Drug Abuse and the National Institute on Alcohol Abuse and Alcoholism, the study is supported by eight other NIH institutes and offices, as well as the Centers for Disease Control and Prevention and other federal partners.
