Commentary: Insights from across diagnostic boundaries: ADHD in the RDoC era – a commentary on Scerif and Baker () / Alysa E. DOYLE in Journal of Child Psychology and Psychiatry, 56-3 (March 2015)

Titre : Commentary: Insights from across diagnostic boundaries: ADHD in the RDoC era – a commentary on Scerif and Baker () Type de document : Texte imprimé et/ou numérique Auteurs : Alysa E. DOYLE, Auteur Article en page(s) : p.274-277 Langues : Anglais (eng) Mots-clés : Attention-deficit/hyperactivity disorder RDoC framework shared risk mechanisms child psychopathology genetic studies Index. décimale : PER Périodiques Résumé : Unbiased genomewide association studies of tens of thousands of individuals are transforming our understanding of the origins and structure of psychopathology across the lifespan. Together with findings from epidemiology and cognitive neuroscience, these recent molecular genetic studies underscore the importance of studying phenotypes across as well as within conventional psychiatric diagnoses in order to construct a more pathophysiologically grounded taxonomy from the bottom up. Such efforts, promoted by NIMH's Research Domain Criteria (RDoC) framework, are critical to developing more accurate models of the risk mechanisms that are shared and distinct across various psychopathologic outcomes. In turn, these models could reveal new treatment targets and early intervention opportunities. In their article in the 2015 JCPP Annual Research Review, Scerif and Baker remind us that bottom-up insights into psychiatric illness might also be gained by examining specific genetic disorders that often fall within the purview of pediatrics and neurology. These authors note high rates of symptoms of attention-deficit hyperactivity disorder (ADHD) in syndromes with known and often monogenic genetic causes (e.g. Fragile X) and suggest that studying the ADHD-like phenomena in these conditions may provide insight into ADHD itself. This commentary highlights themes from Scerif and Baker's review that overlap with the core tenets of RDoC and notes their significance for advancing our understanding of ADHD in the coming years. It concludes by suggesting ways in which further attention to the RDoC framework could also enhance Scerif and Baker's agenda.

Titre : Accuracy of phenotyping children with autism based on parent report: what specifically do we gain phenotyping “rapidly”? Type de document : Texte imprimé et/ou numérique Auteurs : Zachary WARREN, Auteur ; Alison VEHORN, Auteur ; Elizabeth DOHRMANN, Auteur ; Amy NICHOLSON, Auteur ; James S. SUTCLIFFE, Auteur ; Jeremy VEENSTRA-VANDERWEELE, Auteur Année de publication : 2012 Article en page(s) : p.31-38 Langues : Anglais (eng) Mots-clés : Autism ASD genetic studies rapid phenotyping Index. décimale : PER Périodiques Résumé : Autism spectrum disorder (ASD) is considered among the most heritable of all neurodevelopmental and psychiatric disorders, but identification of etiologically significant genetic markers and risk variants has been hampered by a lack of sufficiently large samples. Rapid phenotyping procedures, where self-report measures are used instead of extensive clinical assessment, have been proposed as methods for amassing large genetic databases due to their hypothesized time-efficiency and affordability. We assessed the diagnostic accuracy of potential rapid phenotyping procedures using the Social Communication Questionnaire and the Social Responsiveness Scale in a sample of 333 children who also received extensive phenotypic assessments. While the rapid phenotyping measures were able to accurately identify a large number of children with ASD, they also frequently failed to differentiate children with ASD from children with other complex neurobehavioral profiles. These data support the continued need of expert clinical validation in combination with rapid phenotyping procedures in order to accurately amass large-scale genetic collections of children with ASD.
