Summary
In this chapter, we review studies of multilingual people with language impairments, specifically autism, dyslexia, and developmental language disorder in children, and aphasia and traumatic brain injury in adults. We address three topics that have emerged: disadvantages and advantages of being multilingual, the manifestation of impairments across different languages, and cross-language effects following intervention. Whereas the field of language impairment and bilingualism has seen a growth in the number of publications, only a few studies have focused specifically on multilingual people, and even fewer have compared multilingual to bilingual individuals. Methodological differences among the studies and the limited amount of data for each communication disorder impede our ability to draw consistent conclusions. Despite these limitations, we discuss common themes and point to future directions. Furthermore, we propose that the study of more than two languages can add to our understanding of key aspects of language impairment, representation, and processing.
