Do you ever wonder what happens inside your mouth when you speak or swallow? While we all take for granted that we have the ability to speak (and swallow) A LOT of work happens behind the curtain. Our mouth (aka oral cavity) is where the sounds we hear are fine tuned using numerous muscles and other anatomy of the oral and nasal cavities. For kiddos sometimes these muscles and articulators simply do not want to cooperate which is usually why adults are unable to understand them or why they have difficulty efficiently chewing and swallowing their food. Speech-language pathologists evaluate the functioning of the mechanisms needed to produce intelligible (clear) speech sounds and ensure safe chewing/swallowing. They also are highly trained to provide treatment when these mechanisms are not efficient. Check out this video to see what our mouth looks like while we speak, sing, playing instruments, and swallow!
Childhood Apraxia of Speech (CAS)
Childhood Apraxia of Speech (CAS) is a motor speech disorder. CAS is a relatively uncommon disorder (1-2 children per 1,000= 0.1-0.2%) and one of the lesser known disorders treated by Speech-Language Pathologists. There are some identified causes of CAS (e.g., stroke, trauma, chromosomal abnormalities) but we are not truly sure of all of the causes.
In a nutshell:
The child knows what he/she wants to say and the brain sends the message to the mouth (lips, jaw, and tongue) for appropriate placement to produce sounds, but the mouth doesn't cooperate.
