DCD vs Childhood Apraxia of Speech: the difference

Both can make a young child seem clumsy or hard to understand — but one is about how the body moves, and the other is about how the mouth plans speech.

In short

Developmental Coordination Disorder (DCD) is a motor-coordination difference — a child's body finds everyday physical skills harder than expected for their age, like running, hopping, doing buttons, using cutlery or handwriting, even though they are trying their best. Childhood Apraxia of Speech (CAS) is a motor-speech difference — the brain struggles to plan and sequence the precise movements of the lips, tongue and jaw needed to say sounds and words clearly, so speech comes out inconsistent and hard to understand. In short: DCD is mainly about whole-body and hand movement; CAS is specifically about planning the movements for talking. The two can sometimes overlap, but they are distinct.

How they differ in everyday life

With DCD, you might notice a child who is bumping into things, late to walk or jump, struggles to ride a tricycle, finds dressing and using scissors frustrating, or whose drawing and writing look far behind their classmates. The thinking and language may be perfectly fine — it is the physical doing that lags.

With CAS, the standout feature is speech. The same word may come out differently each time they try it, longer words fall apart, sounds get left out or jumbled, and even a parent can find their child genuinely hard to understand. Children with CAS often understand far more than they can say, which can be frustrating for them — they know exactly what they want, but the mouth won't cooperate.

A helpful way to hold it: DCD shows up when the body moves; CAS shows up when the mouth tries to make words. A child can have one, the other, or — in some cases — both, which is why a proper look at the whole child matters.

When to seek a look

If your child seems much clumsier than peers, or is consistently very hard to understand by age 3, a developmental check is worthwhile — not to label, but to understand and support early. Both DCD and CAS respond well to the right, consistent therapy, and earlier support is gentler and more effective. There is no need to wait and worry.

The Pinnacle way

This is general information, not a diagnosis — a clinical AbilityScore® and any diagnosis are formed only at a Pinnacle Blooms Network centre, under qualified clinician care, never from an app or form. Our therapists observe how your child moves, plays and talks, then tailor support — occupational therapy helps with the coordination side of DCD, while speech therapy uses motor-speech approaches for apraxia. Many children thrive with a blend.
