What is Childhood Apraxia of Speech?
⁣
Childhood Apraxia of Speech or CAS is when there is an interruption in messaging of the brain to the mouth and lips to receive a clear signal to plan movements. This means that the mouth, lips and teeth have the ability to move but they are not getting the correct instruction from the brain to move. ⁣It can appear the child is frozen in response. ⁣

An example is one morning you might ask your child what do they want for breakfast, and they will give you a quick response however maybe the next day they won’t. You may be asking yourself “I don’t understand why they are not responding to me they just responded to me yesterday?!” That’s the complexity of CAS.⁣
⁣
CAS is a motor based neurologic speech disorder. In short it is involved with the ability to plan and execute the movement of the facial structures for speech production. There are different motor speech therapy methods for CAS, including PROMPT therapy, DTTC and others

Cause of Childhood Apraxia of Speech

Because Childhood Apraxia of Speech is known as a motor speech disorder, most of the time the cause is unknown, but a MRI or CT scan would allow a look into your child’s brain. This may expose a genetic disorder, syndrome, stroke or brain injury that may have cause Childhood Apraxia of Speech.

Treatment

Treatment in general is focused on the movement versus the sound that is actually produced. Differences in therapy include more frequent sessions and motor learning.

Therapy evaluation is usually broken into three sections:   

  • Oral Motor activities: Though weakness of the lip, tongue, jaw are usually not accompanied with CAS, an SLP will evaluate them by having the child complete different speech motor tasks and might even use a lollipop!
  • Speech Melody: Often children with CAS have a disconnect in the use of stress and tone and pauses in sentences, an SLP will evaluate this by asking them questions that allow for the productions of key words.
  • Saying Sounds: An SLP, will have your child say both consonants and vowels aloud and see if pronunciation is correct.
