Apraxia, sometimes called verbal apraxia or acquired apraxia of speech, is a motor speech disorder. This means that the problem arises from poor motor coordination. A person with apraxia has trouble with the muscle control that is needed to form words. Patients may develop acquired apraxia of speech regardless of how old they are, but it more commonly afflicts adults. As opposed to acquired apraxia, developmental apraxia is present in children from birth.
