| Context | The presence of apraxia  should be investigated in all aphasic patients, as it may interfere with  the performance of acts requested through verbal command. Students of aphasia should be aware of the fact that patients do not "complain" of  apraxia and that, except for the extreme forms of ideational apraxia, the  phenomenon is neither immediately disruptive to the patient´s life nor  evident to the examiner. The reader is referred to Geschwind (1975) for a  comprehensive view of the phenomenon.
