Moderator Effects of Working Memory on the Stability of ADHD Symptoms by Dopamine Receptor Gene Polymorphisms during Development
Peer reviewed Peer reviewed

Trampush, Joey W.; Jacobs, Michelle M.; Hurd, Yasmin L.; Newcorn, Jeffrey H.; Halperin, Jeffrey M. – Developmental Science, 2014
We tested the hypothesis that dopamine D1 and D2 receptor gene (DRD1 and DRD2, respectively) polymorphisms and the development of working memory skills can interact to influence symptom change over 10 years in children with attention-deficit/hyperactivity disorder (ADHD). Specifically, we examined whether improvements in working memory maintenance…

Ronald, Angelica; Edelson, Lisa R.; Asherson, Philip; Saudino, Kimberly J. – Journal of Abnormal Child Psychology, 2010
Behaviors characteristic of autism and ADHD emerge in early childhood, yet research investigating their comorbidity has focused on older children. This study aimed to explore the nature of the relationship between autistic-like traits and ADHD behaviors in a community sample of 2-year-olds.
