“…Recent work has highlighted the need to facilitate the identification of speech- and language-related developmental disorders and improve the design of early intervention by exploring risk factors in population-based samples ( Raghavan et al, 2018 ). Converging evidence supports comorbidities among different speech/language disorders (e.g., Dyslexia and DLD; Bishop & Snowling, 2004 ; Catts, Adlof, Hogan, & Weismer, 2005 ) and also between speech/language disorders and motor disorders (e.g., developmental coordination disorder [DCD]; Kaplan, Dewey, Crawford, & Wilson, 2001 ; Scabar, Devescovi, Blason, Bravar, & Carrozzi, 2006 ; Selassie, Jennische, Kyllerman, Viggedal, & Hartelius, 2005 ; Zwicker, Missiuna, & Boyd, 2009 ) or attentional disorders (e.g., attention deficit hyperactivity disorder [ADHD], Box 1 ; Donaher & Richels, 2012 ; Kaplan et al, 2001 ; Kovac, Garabedian, Du Souich, & Palmour, 2001 ; Mueller & Tomblin, 2012 ; Redmond, 2016 ; Selassie et al, 2005 ; Westerlund, Bergkvist, Lagerberg, & Sundelin, 2002 ; Zwicker et al, 2009 ). This research suggests that it is unusual to have discrete, categorical developmental disorders, and that it may be more efficient to search for underlying deficits that can be identified across disorders in large samples of children.…”
