Abstract
ABSTRACT The case study explores bilingualism and neurodegenerative disorders, specifically progressive supranuclear palsy (PSP) with speech and language disorder (PSP-SL). It features a 78-year-old Mexican American woman who exhibits echolalia only in response to Spanish. This selective impairment suggests unevenly affected language control mechanisms despite her proficiency in both languages. Cognitive function is evaluated with neuropsychological tests; she's diagnosed with PSP-SL, depression, and anxiety. Echolalia in response to one language implies complex phonological retrieval mechanisms. Such observations prompt further inquiry into bilingual language control and processing mechanisms. The case supports evidence that bilingualism may attenuate neurodegeneration effects, suggesting better inhibitory control over disinhibited speech through enhanced executive functioning benefits.
