Definition:
Childhood apraxia of speech (CAS) is a communication disorder in which a child can understand language and formulate words to say, but the brain is unable to move or coordinate the muscles of the mouth to speak those words. It is not a problem with the muscles but with the brain's ability to control them. CAS can improve with intensive speech therapy, and children with apraxia also often use sign language or communication devices to help them communicate while they struggle with speech.
Also Known As: Apraxia, CAS
