[Agraphia and preservation of music writing in a bilingual piano teacher].
A bilingual virtuoso piano teacher developed aphasia and amusia, probably due to cerebral embolism. The perfectly demarcated and unique lesion was located in the left posterior temporoparietal region. Language examinations in French and Italian demonstrated entirely comparable difficulties in both languages. The linguistic course was favorable after a period of auditory agnosia and global aphasia. Language became fluent again 3 months after the onset, with a marked vocabulary loss and phonemic paraphasias with attempts at self-correction. Repetition was altered markedly with a deficit in auditory comprehension but no remaining elements of auditory agnosia. Reading was possible, but with some difficulty and total agraphia and acalculia persisted. Musical ability was better conserved, particularly with respect to repetition and above all to writing, the sparing of the latter constituting a fairly uncommon dissociation in relation to agraphia. Findings are discussed in relation to data in the literature concerning hemispheric participation in various musical tasks.
