Childhood Apraxia of Speech (CAS) is a motor speech disorder making it difficult for a child to speak.  A child with CAS knows what he/she wants to say, but his/her brain has difficulty planning or sequencing the complex motor movements necessary to say the words clearly.  CAS is not due to muscle weakness.  The breakdown occurs with how the brain tells the muscles to move.  Your child may have inconsistent errors when saying words, increased difficulty with longer or more complex connected speech, vowel errors/distortions, prosodic disturbances, and can be difficult to understand.  Treatment should be frequent and focus on principles of motor learning to target the child’s ability to plan and program motor movements using practice and repetition in speech tasks.
