The multilingual naming test in Alzheimer's disease: clues to the origin of naming impairments.

摘要: The current study explored the picture naming performance of patients with Alzheimer’s disease (AD). First, we evaluated utility multilingual test (MINT; Gollan et al., 2011), which was designed to assess skills in speakers multiple languages, for detecting impairments monolingual AD and amnestic mild cognitive impairment (MCI). If MINT were sensitive linguistic AD, using it clinical practice might have advantages over tests exclusively English monolinguals. We found that can be used both monolinguals bilinguals: A 32-item subset is best distinguishing from controls, while full assessing degree bilingualism language dominance bilinguals. then investigated mechanisms underlying AD. To this end, item characteristics predicted differences between controls. contextual diversity imageability, but not word frequency (nor words’ number senses), contributed unique variance explaining These findings suggest a semantic component (modulated by names’ richness network size).
