Adolescence is a critical period marked by rapid brain development and the onset of many mental health disorders. Brain MRI studies during adolescence, especially when paired with behavioral phenotypes and information about genetic risk factors, hold promise to advance early identification of mental health risk and spur the creation of targeted treatments to improve patient function, prognosis, and quality of life. However, prospective neuroimaging is costly and time-intensive, and individuals who participate may not be reflective of the general population. These challenges are compounded when examining adolescents, as many families lack the time, energy, or resources to participate in studies that utilize research-grade imaging. Repurposing clinical MRIs obviates many of the challenges of neuroimaging research. Here we describe the Brain-Behavior-Genetics study protocol. This protocol describes procedures used to recruit participants with recent high-quality clinical brain MRIs and prospectively acquire genetic and socio-behavioral data, resulting in a highly cost-efficient design that harnesses a vast and underutilized neuroscientific resource.
