Developmental Language Disorder (DLD)

📖 Overview

Developmental Language Disorder (DLD) is one of the most common childhood conditions — affecting around 1 in 14 children — yet it is poorly recognised and frequently missed. DLD involves significant, persistent difficulties with understanding and using spoken language that are not explained by hearing loss, intellectual disability, or another identified condition.

DLD affects the processing of language: understanding what people say, constructing sentences, finding words, following complex instructions, and organising language in narrative or conversation. It is a hidden difficulty — children with DLD often look fine and may have managed to partially compensate for their difficulties.

DLD is different from a speech sound disorder (difficulty pronouncing sounds) or language delay that catches up. DLD is persistent and has significant effects on learning, literacy, and social development throughout life if not identified and supported.

Children with DLD often struggle in school without anyone understanding why. They may appear to understand when they do not, use social context to guess meanings, and develop workarounds that hide their difficulties from teachers. By secondary school the language demands of the curriculum often expose the difficulties more clearly.

DLD commonly co-occurs with dyslexia, dyspraxia, ADHD, and reading difficulties. Speech and language therapy is the primary support. Environmental adaptations — simplified language, visual supports, checking understanding — are important across all settings.
