What this research studies

You would join a long-term project at CU Boulder that follows children who were about 9–10 years old into their teen years. At the first visits participants had state-of-the-art brain scans, thinking and memory tests, physical checks, and biological samples such as saliva or blood. The team asks about substance use, mood, school and social life, and uses phone or app check-ins every six months plus yearly in-person interviews to monitor changes. The site works hard to keep families involved so researchers can learn how early experiences and exposures relate to brain development and mental health.

Who could benefit from this research

Good fit: Ideal candidates are children around 9–10 years old and their caregivers who can attend in-person imaging and periodic follow-up visits at the CU Boulder site.

Not a fit: Adults, very young children outside the target age range, or people unable to come for repeated in-person visits or phone/app follow-ups would not benefit directly from joining this site.

Why it matters

Potential benefit: If successful, this work could help doctors and families spot early patterns that raise risk for depression, anxiety, substance problems, or learning issues and guide better prevention or support.

How similar studies have performed: Previous brain-imaging cohort studies have linked teen substance use and life experiences to brain and behavior changes, but the ABCD consortium's large national sample and repeated follow-up make its approach more powerful and relatively novel.
