Abstract
In a 63-year-old man with severe Broca's aphasia, pure tone audiometry and a series of auditory evoked responses demonstrated preservation of primary auditory pathways. Because he did not speak, the standard language test of aphasia was performed for Broca's aphasia. Since it was impossible to continue further tests, we introduced objective methods to evaluate his aphasic disorder. Phonolaryngograms showed that he was unable even to utter vowel sounds. An electronystagmographic study of eye tracking and OKN revealed abnormal eye movements consistent with a functional disorder in the left cerebral hemisphere. Eye movements during reading clearly showed depression of saccadic gaze phases. Although neurophysiological assessment with writing was not done, it was clear that writing was no better than painting.
