[A case of conduction aphasia with specific jargon utterance].

We report a patient with bilateral hemispheric lesions caused by two episodes of cerebral infarction who exhibited conduction aphasia with unique jargon. The patient was an 84-year-old, right-handed man. Beginning after the second episode of cerebral infarction (defined as the time of symptom onset), neologistic jargon and an iterative pattern of phonemic variation became prominent, whereas phonological paraphasia and conduite d'approche were observed in the patient's overall speech.

Pure agraphia after infarction in the superior and middle portions of the left precentral gyrus: Dissociation between Kanji and Kana.

The present study describes a Japanese patient with pure agraphia displaying differential disturbances in processing Kanji (morphogram) and Kana (syllabogram) letters after an infarction in the middle and superior portions of the left precentral gyrus. Kana errors reflected the patient's difficulty with retrieving both motor and visual letter images, whereas Kanji errors included partial letter stroke omissions or additions. This present case suggests that differences in writing disturbances between Kana and Kanji letters are caused by a differential dependency on letter motor images.

Relationships among Communication Self-Efficacy, Communication Burden, and the Mental Health of the Families of Persons with Aphasia.

Background: The purpose of this study was to elucidate the relationships among communication self-efficacy (SE), communication burden, and the mental health of the families of persons with aphasia using structural equation modeling (SEM).

Methods: This study examined 110 pairs of persons with aphasia receiving home care and 1 family caregiver per person with aphasia. The survey items for this study consisted of the Communication Self-efficacy Scale, the Communication Burden Scale, the Geriatric Depression Scale-Short Form-Japanese, and the Health-Related Quality of Life: SF-8 Health Survey.

[Aphasia--a new as well as old problem].

Alajouanine (1956) established a concept of jargon as a speech symptom of aphasia and gave clinical descriptions of three types of jargon-undifferentiated, asemantic (neologistic) and paraphasic (semantic) jargon. Several case-reports of undifferentiated jargon in Japanese language have been published in clinical aphasiology. On the other hand language development of jargon-type in normal children was reprorted in developmental psychology.
