General Clinical Considerations
Language is a means by which people communicate with each other using verbal symbols. Dysphasia may be defined as a disorder of language due to brain damage. This monograph deals with disorders of language, not disorders of speech. Speech refers to the mechanical process of articulation, which can be disturbed by weakness, slowness, or incoordination of the muscles of the glossopharyngeal apparatus. Such disturbances would be termed dysarthria, dysphonia, or mutism. The term dysphasia is applied to a neurological disorder resulting from damage to those regions of the cerebral hemispheres which form the anatomical basis for the human capacity for language.
