What is Developmental apraxia of speech mean?
Developmental verbal dyspraxia (DVD), also known as childhood apraxia of speech (CAS) and developmental apraxia of speech (DAS), is a condition in which children have problems saying sounds, syllables and words. This is not because of muscle weakness or paralysis. The brain has problems planning to move the body parts (e.g., lips, jaw, tongue) needed for speech. The child knows what they want to say, but their brain has difficulty coordinating the muscle movements necessary to say those words.
The exact cause of this disorder is usually unknown. Many observations suggest a genetic cause of DVD, as many with the disorder have a family history of communication disorders. The gene FOXP2 has been implicated in many studies of the condition, and when this is the cause, the condition is inherited in an autosomal dominant manner, however roughly 75% of these cases are de novo.
There is no cure for DVD, but with appropriate, intensive intervention, people with this motor speech disorder can improve significantly.
