What is Apraxia of Speech?
Apraxia is a motor speech sound disorder. It is sometimes referred to as Apraxia of Speech (AOS) or Childhood Apraxia of Speech (CAS). Apraxia is neurological meaning that it affects the brain pathways involved in planning the sequence of movements needed to produce speech. The brain knows what it wants to say, but cannot properly plan and sequence the required speech sound movements. A child might not be able to move their lips or tongue in the right ways, even though their muscles are not weak. Sometimes, the child might not be able to say much at all.
