Phonological short-term memory in logopenic variant primary progressive aphasia and mild Alzheimer's disease

摘要: It has been argued that individuals with logopenic variant primary progressive aphasia (lvPPA) have an impairment of the phonological loop, which is a component short-term memory (STM) system. In contrast, this type not thought to be present in mild typical Alzheimer's disease (AD). Thus, one would predict people lvPPA score significantly lower than matched AD group on tasks require STM. current study, was compared age, education, and general cognitive functioning. For subset involved pseudowords, groups were healthy control age education. The more impaired all required STM, including pseudoword tasks, but there no significant differences between these visuospatial Compared controls, performed worse repetition reading while did differ from controls tasks. These findings are consistent hypothesis STM lvPPA.
