Invisible Disorder Affects 1 in 10 Children

Developmental language disorder (DLD), an often-overlooked neurodevelopmental condition, affects an estimated 7-10% of school-age children, yet remains largely unknown. This disorder impedes language acquisition and usage without apparent reasons such as intellectual disability or hearing loss, impacting comprehension or expression.

Unlike more recognized conditions, DLD is invisible, lacking physical indicators. Children with DLD may perform well in casual conversation but struggle with complex language found in textbooks or abstract concepts. Symptoms can include difficulty following instructions, short sentences, or grammatical errors, often misattributed to laziness or behavioral issues.

Recognizing DLD early is critical, as untreated, it can lead to persistent academic, social, and emotional challenges. However, with timely diagnosis and specialized support, including speech therapy, school adaptations, and consistent home involvement, children with DLD can achieve success and thrive.
