Abstract
Background: One of the distinguishing characteristics of logopenic progressive aphasia (LPA) is phonologic errors, but few data exist that document the frequency of such errors across a variety of language tasks.Aims: The primary aim of this study was to investigate the frequency of phonologic errors across a variety of spoken language tasks in participants with LPA.Methods & Procedures: Detailed descriptive analysis was based on data obtained from video recordings of 22 participants with LPA. Nine tasks were analysed for phonologic errors.Outcomes & Results: All participants made some phonologic errors, with presence/absence of such errors varying across tasks. Tasks that were most likely to elicit phonologic errors were reading nonwords, repetition of multisyllabic words, reading irregular words, and the 15-item Boston Naming Test. Factors such as task nature or complexity, severity of aphasia, and, possibly, education influenced the frequency of phonologic errors.Conclusions: Our findings support the current consensus criteria that indicate that phonologic errors are a frequent but not a required characteristic for a diagnosis of LPA.
