Background: Previous research, although scarce, has indicated that the general public is still relatively unaware of developmental language disorder (DLD), one of the most common (neuro)developmental disorders. Raising awareness would increase timely involvement in intervention procedures. Aims: To examine public awareness of DLD in the…

Prevalence of developmental disorders (DDs) has been increasing worldwide. This study identifies a trend in their prevalence and incidence, using nationwide population-based data to analyze the characteristics of children with DDs in Korea. The prevalence of DDs steadily increased by more than four times (from 0.6 to 2.5) from 2003 to 2017. Boys…
