News Context: That lag in connection development may help explain why people with ADHD get easily distracted or struggle to stay focused. What's more, the new findings, and the methods used to make them, may one day allow doctors to use brain scans to diagnose ADHD -- and track how well someone responds to treatment. The researchers found lags in development of connection within the internally-focused network, called the default mode network or DMN, and in development of connections between DMN and two networks that process externally-focused tasks, often called task-positive networks, or TPNs.
Paper Context: Our finding of maturational lag specifically in connections within and between these networks suggests a developmental etiology for the deficits proposed in these models. These advances raise possibilities for investigating maturational lag in ADHD in the developing ICN architecture of the brain . Thus, conventional seedbased strategies are likely to produce summary measures that do not capture underlying fine-grained patterns of variation or can miss trends that are detectable only when looking across large populations of connections.
