What this research studies

You would be part of a group first enrolled as 12–21 year olds and followed for years to see how alcohol use relates to brain and behavioral changes. Each year participants complete brain scans (MRI, DTI, resting and task fMRI), cognitive testing, clinical and behavioral questionnaires, and biological sampling, with some visits done in person and others via app or remote tools. New sleep and physical activity tracking and advanced imaging methods are being added to better link drinking patterns with brain development and function. The study includes hundreds of people across multiple sites and has kept most participants in the project over time.

Who could benefit from this research

Good fit: Ideal candidates are teens and young adults (roughly ages 12–25) with varying histories of alcohol use who can complete MRI scans, questionnaires, and periodic follow-up visits or remote testing.

Not a fit: Older adults outside the adolescent/young adult age range or people unwilling to undergo MRI, share information about alcohol use, or participate in follow-up are unlikely to benefit directly from joining.

Why it matters

Potential benefit: If successful, this work could help doctors and families know when and how adolescent drinking harms the brain and guide better prevention and treatment for young people.

How similar studies have performed: Previous longitudinal projects, including earlier NCANDA work, have linked adolescent drinking to altered brain development, and this extended follow-up with newer imaging aims to provide clearer, longer-term evidence.
