A scoping review of the assessment of agrammatism in individuals with Broca's Aphasia and the non-fluent variant of Primary Progressive Aphasia
2:30 PM - 2:45 PMPresentation summary
Aim: This scoping review will evaluate how agrammatism has been assessed in individuals with Broca's Aphasia and the non-fluent variant of PPA, across different languages, with the view to guiding development of a clinical assessment tool.
Methods: A comprehensive search based on keywords related to grammar/morphosyntax, assessment, and aphasia, was conducted on MEDLINE. Articles identified during the search were screened by two reviewers at the title and abstract and full text levels. Inclusion criteria were i) the aim to assess agrammatism in at least one adult with agrammatism, ii) reporting original data, and iii) published in English. One reviewer extracted data on all articles and another reviewer completed reliability on 20% of articles.
Results: A total of 465 papers were screened at title and abstract level, of which 130 were assessed at full text for eligibility. Of these, 88 papers were included for data extraction. They crossed 17 languages, with English being evaluated in 61% of articles. A total of 1263 individuals with agrammatism were studied (469 male, mean age = 54.6 yrs). Of these, 62% had stroke-related agrammatism. An in-depth analysis of specific tasks and grammatical measures used in each article will be presented.
Conclusions: Researchers across countries use various tasks and examine a wide range of grammatical measures to assess agrammatism. The clinical feasibility of performing these grammatical measures is questioned. Suggestions for tackling these barriers to efficient and reliable assessment will be presented.
Key messages
1. Deeper understanding of what agrammatism is
2. Tasks and measures used to assess agrammatism in individuals with Broca's aphasis and non fluent PPA
3. A different method of assessing agrammatism
