What does developmental verbal dyspraxia ( DVD ) stand for?

Where does apraxia of speech fall on the Levelt model?

According to the Levelt model, apraxia of speech would fall into the articulation region. The individual does not suffer from a language deficiency, but has difficulty in the production of language in an audible manner. Notably, this difficulty is limited to vocal speech, and does not affect sign-language production.

What does ideomotor apraxia mean in medical terms?

Ideomotor apraxia is typically due to a decrease in blood flow to the dominant hemisphere of the brain and particularly the parietal and premotor areas.

Why are speech sound disorders often confused with CAS?

Some speech sound disorders often get confused with CAS because some of the characteristics may overlap. These speech sound disorders include articulation disorders, phonological disorders and dysarthria.

What causes a child to have developmental apraxia?

CAS may be the result of brain (neurological) conditions or injury, such as a stroke, infections or traumatic brain injury. CAS may also occur as a symptom of a genetic disorder, syndrome or metabolic condition. For example, CAS occurs more frequently in children with galactosemia. CAS is sometimes referred to as developmental apraxia.
