# Developmental Language Disorder vs Childhood Apraxia of Speech in Children Canonical: https://pinnacleblooms.org/ask/what-is-the-difference-between-developmental-language-disorder-and-childhood-apraxia-of-speech-in-children Publisher: Pinnacle Blooms Network / Bharath Healthcare Laboratories Private Limited Developmental Language Disorder (DLD) is a difficulty with language itself — understanding and building words, sentences and grammar — while Childhood Apraxia of Speech (CAS) is a motor-planning difficulty where the child knows what to say but struggles to coordinate the mouth movements to say it. DLD affects the message; CAS affects the physical production of speech, and some children show features of both. AbilityScore® is part of Pinnacle’s developmental assessment. Diagnosis, where needed, requires an appropriately qualified healthcare professional. *When your child's words don't come the way you expected, knowing whether the struggle is with understanding language or with the mouth's motor planning changes everything about how you help.* ## In short **Developmental Language Disorder (DLD)** is a difficulty with *language itself* — understanding words, putting sentences together, and learning grammar and vocabulary — even though the child has no obvious cause like hearing loss or autism. **Childhood Apraxia of Speech (CAS)** is a *motor-planning* difficulty — the child knows exactly what they want to say, but the brain struggles to coordinate the precise movements of the lips, tongue and jaw to say it clearly. In short: DLD is mostly about the *language* (the message), while CAS is about the *speech* (the physical act of producing sounds). Some children have features of both, which is exactly why a careful assessment matters. ## How they differ in everyday life **Developmental Language Disorder often looks like:** - A smaller vocabulary than peers, or difficulty finding the right words - Short, simple or jumbled sentences; mixing up word order or grammar - Trouble following longer instructions or understanding questions - Difficulty telling a story or explaining what happened in order - The *content and structure* of language lags, even when individual sounds are clear **Childhood Apraxia of Speech often looks like:** - Sounds and words come out differently each time the child tries (inconsistent errors) - Groping or visible effort, as if the mouth is 'searching' for the position - Trouble with longer or more complex words more than short ones - Speech that is hard to understand even though the child clearly *has* the words and ideas - Difficulty smoothly moving from one sound to the next A helpful way to picture it: a child with DLD may speak clearly but with limited or muddled *language*; a child with CAS may have rich ideas and understanding but a *mouth that won't cooperate* to say them. Because the underlying difficulty is different, the therapy looks different too — and a child can occasionally show signs of both. ## When to seek a check Seek a developmental and speech check if, by around two years, your child has very few words; if speech is much harder to understand than other children the same age; if your child seems to understand but cannot get words out clearly; or if you simply feel their talking is not progressing. Earlier support always helps — you never need a certain diagnosis before asking for guidance. ## The Pinnacle way AbilityScore® is part of Pinnacle’s developmental assessment. Diagnosis, where needed, requires an appropriately qualified healthcare professional — never from an app, a checklist or an online form. A speech-language pathologist listens closely to *how* your child's speech and language are developing to tell apart a language-based difficulty from a motor-planning one, then shapes the right plan.
