Abstract

Speech movement disorders, as a consequence of nervous system impairment, are relatively common, being associated with numerous nervous system diseases, stroke, brain trauma, or congenital abnormalities. Disorders of speech movements may be manifest as the only problem in communication or they may occur with impairments in language function. For this reason, and as a matter of scientific and clinical convenience, speech and language typically are considered to be products of distinct nervous system operations. On the one hand, speech can be viewed as the process whereby controlled movements are transformed into sound, thus providing the medium through which semantically significant messages are transmitted. By contrast, language is an organized system of consistent abstract symbols that provides the meaning-based format for speech.
