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.

The National Institutes of Health today released to the scientific community an unparalleled dataset from the Adolescent Brain Cognitive Development (ABCD) study. To date, more than 7,500 youth and their families have been recruited for the study, well over half the participant goal. Approximately 30 terabytes of data (about three times the size of the Library of Congress collection), obtained from the first 4,500 participants, will be available to scientists worldwide to conduct research on the many factors that influence brain, cognitive, social, and emotional development. The ABCD study is the largest long-term study of brain development and child health in the United States.
This interim release provides high-quality baseline data on a large sample of 9-10-year-old children, including basic participant demographics, assessments of physical and mental health, substance use, culture and environment, neurocognition, tabulated structural and functional neuroimaging data, and minimally processed brain images, as well as biological data such as pubertal hormone analyses. The data will be made available through the National Institute of Mental Health (NIMH) Data Archive, which can be accessed by researchers who obtain a free NIMH Data Archive account. All personally identifiable information is removed from the data to ensure participant confidentiality and anonymity.

A new nationwide study will follow thousands of children for 10 years, starting in elementary school, in an attempt to answer questions about the risks and protective factors for adolescent substance use on the developing brain. The Adolescent Brain Cognitive Development (ABCD) Study will track exposure to substances (including nicotine, alcohol and marijuana), academic achievement, cognitive skills, mental health, brain structure and function, and many other variables.
By starting with youth before adolescence, the scientists will be able to assess the effects of the age of different experiences (trauma, poor nutrition, substance use) on brain development.
The study, funded by the National Institutes of Health, will begin with 11,500 children ages 9 and 10, before they start substance use, at 19 sites around the country. Recruitment for the trial is scheduled to launch in September.
