The approach presented in this study proved to be a helpful instrument to overcome the limitation of heterogeneity, however, it remains unable to identify subgroups of children based on connectivity or behavioral profile. Therefore, future studies should focus on further characterizing the heterogeneity in ADHD and control populations and identify subgroups of individuals that might present specific patterns of connectivity or behavior that, in turn, may be linked to specific patterns of symptoms, outcomes, or response to treatment.
