“…These situations are associated with several neurodevelopmentally relevant pathologies, including attention deficit/hyperactivity disorder (ADHD; e.g., Faraone et al, 1993;Place, Wilson, Martin, & Hulsmeier, 2000), learning disabilities (e.g., Barnett, Clarizio, & Payette, 1996;McLeskey & Grizzle, 1992), and premature birth or low birth weight (Buck, Msall, Schisterman, Lyon, & Rogers, 2000;Pinto-Martin et al, 2004), as well as mental retardation. Children may also be assigned to special education systems with diagnoses of conduct disorder or oppositional defiant disorder, which are themselves often comorbid with ADHD (e.g., Déry, Toupin, Pauzé, & Verlaan, 2004;Place et al, 2000).…”
