Developing an understanding of factors that lower the severity of ADHD and enhance cognitive functioning is highly beneficial considering the high cost of ADHD (Birnbaum et al., 2005; Marks et al., 2009) and the difficulties observed throughout the lifespan (Wilens, Biederman, & Spencer, 2002). Although further research needs to consider genetic and environmental factors that may bring about changes in neuropsychological functioning and ADHD severity, our findings suggest that interventions directed towards improving neuropsychological functioning in young children with elevated ADHD symptoms (Halperin et al., 2012; Tamm et al., 2012) may have the potential to mitigate the adverse long-term course of the disorder.
