The MTA at 8 Years: Prospective Follow-up of Children Treated for Combined-Type ADHD in a Multisite Study

TL;DR: Type or intensity of 14 months of treatment for ADHD in childhood does not predict functioning 6 to 8 years later, and early ADHD symptom trajectory regardless of treatment type is prognostic, implying that children with behavioral and sociodemographic advantage, with the best response to any treatment, will have the best long-term prognosis.

ADHD Comorbidity Findings From the MTA Study: Comparing Comorbid Subgroups

TL;DR: Three clinical profiles are indicated, ADHD co-occurring with internalizing disorders (principally parent-reported anxiety disorders) absent any concurrent disruptive disorder (ADHD + ANX), ADHD Co-occurred with ODD/CD but no anxiety (AD HD + ODD /CD), and ADHD with both anxiety and O DD/CD may be sufficiently distinct to warrant classification as ADHD subtypes different from "pure" ADHD with neither comorbidity.
