The ABCD is an unprecedented study in the examination of children's brain development [75, 79]. The ABCD study is a longitudinal study of a diverse sample of children from age 9 to 10 to their early adulthood [80]. For more information regarding the ABCD sample, methods, measures, and imaging techniques, please see here [80].
