1/5. "Pure word deafness": implications for assessment and management in communication disorder--a report of two cases.

    In "pure word deafness" after acquired brain injury, the auditory comprehension of words is much more impaired than other aspects of communication or cognition. Two cases are presented, one early and one late presentation. The key to diagnosis of communication disorders is to remember to assess all six basic aspects of language function and to be vigilant for coexisting diagnoses that can complicate such assessment (especially psychiatric diagnoses). rehabilitation management of impaired communication should emphasize the teaching of specific coping mechanisms to the patient and to all others who are involved.

2/5. A case of cortical deafness and anarthria.

    Generally, cortical deafness is not complicated by anarthria and cortical anarthria does not affect auditory perception. We report a case of simultaneous progressive cortical deafness and anarthria. At the age of 70 years, the patient, a woman, noticed hearing problems when using the telephone, which worsened rapidly over the next 2 years. She was then referred to our hospital for further examinations of her hearing problems. Auditory tests revealed threshold elevation in the low and middle frequencies on pure-tone audiometry, a maximum speech discrimination of 25% and normal otoacoustic emissions and auditory brainstem, middle- and long-latency responses. An articulation test revealed abnormal pronunciation. Because of these problems only written and not verbal communication was possible; her ability to read and write was unimpaired. She showed no other neurological problems. brain MRI demonstrated atrophic changes of the auditory cortex and Wernicke's language center and PET suggested low uptake of (18F) 2-fluoro-2-deoxy-d-glucose around the Sylvian fissures in both hemispheres. Neurologically, the patient was suspected of having progressive aphasia or frontotemporal dementia. Her cortical deafness and anarthria are believed to be early signs of this entity.

3/5. When only the right hemisphere is left: studies in language and communication.

    An adult of above normal intelligence, BL, underwent left hemispherectomy at age five, and subsequently graduated from college and has been regularly employed. Using standardized neuropsychological instruments, previous extensive testing had revealed optimal performance for a hemispherectomized subject. To probe communicative abilities in greater detail, and to examine current questions about linguistic superiority of the left hemisphere and "crowding" of right hemisphere functions, 12 additional protocols were administered. BL performed at normal or above on nearly all protocols. However, performance on production of phonemically complex words was effortful, and deficits were seen on two tests requiring comprehension of linguistic contrasts in prosody (Linguistic Prosody Test) and syntax (the Active-Passive Test). These findings support previous claims of reduced ability in specific, circumscribed linguistic functions in the left hemispherectomized person, and lead to suggestions for further testing of communicative competence in individuals with a single intact hemisphere.

4/5. Late language development in a child unable to recognize or produce speech sounds.

    A boy with severe quadriplegia who neither recognized nor uttered speech sounds acquired language. Until the age of 6 years he was considered to be of severely subnormal intelligence. At age 6 years 9 months he was introduced to a manual sign system. Subsequently he was able to read, write, converse, and produce imaginative stories. attention and memory were unimpaired and affective and social responsiveness developed appropriately. The case history demonstrates the selective effects of brain lesions that, despite extensive damage, may spare functional systems necessary for cognitive and linguistic development. It highlights the difficulty in diagnosing and evaluating the intellectual and affective potential of a multihandicapped child without functional hearing or speech and emphasizes the importance of sign language as a communication channel and prerequisite for the acquisition of reading and writing skills.

5/5. learning disabilities and central auditory dysfunction.

    hearing loss, whether peripheral or central, compounds the communication and educational problems of the learning disabled student. A central auditory processing disorder uniquely interferes with both the input and integration of verbal information, further resulting in a potentially permanent cognitive dysfunction during the developmental period of acquisition of language. Illustrative cases are presented that indicate the panorama of cognitive dysfunction associated with the learning disabled status. methods of evaluation and identification and diagnostic criteria are correlated with auditory, visual, and academic performance. Comments regarding clinical awareness, prompt recognition, and ensuing individualized remediation are submitted.
