摘要：We investigate the deterioration of English and Shanghai Chinese (Shanghainese) over two years in a bilingual woman (BYR) with Primary Progressive Aphasia (PPA). Methodological contrasts with Druks and Weekes (2011) provide differing perspectives on bilingual PPA with typologically different languages. They found that LI was better preserved than L2; our longitudinal data suggest more rapid decline in LI than L2 in certain measures. Cases also differed with respect to PPA type, location of neuropathology, language typologies, and possibly stage of disease.
