A brief test of equivalent validity in groups of patients with acquired aphasic syndromes due to both vascular (post stroke aphasia) and neurodegenerative (primary progressive aphasia) pathologies;
- Able to detect the differing patterns of linguistic deficit that characterise the early stages of the three archetypal syndromes of primary progressive aphasia (PPA): namely, semantic dementia (SD), progressive non-fluent aphasia (PNFA), and logopenic progressive aphasia (LPA)
- Capable of detecting and characterising atypical symptom clusters in individuals and groups of patients with PPA
- Usable, after brief training, by clinicians without special expertise in the assessment of language disorders
- Brief enough to form part of an outpatient or ward-based clinical assessment of suspected or established cases
- Sensitive to changes in language integrity secondary to disease progression over twelve months.
