Abstract

A Yugoslavian perfectly bilingual for French and Serb had a limited left middle cerebral artery stroke. He developed a peculiar dysgraphia characterised by the use of Latin characters (French spelling) to transcribe Serb phonemes that would normally have been spelt in the Cyrillic alphabet. This dysgraphia was likely to be due to an impairment of the allographic procedure. It is concluded that allographs of the two alphabets are produced concomitantly in bialphabetical patients during the allographic procedure.
