          Abstract

          Background/Aims: The aims of this study were to validate the newly developed version of theAddenbrooke's Cognitive Examination (ACE-III) against standardised neuropsychological tests and its predecessor (ACE-R) in early dementia. Methods: A total of 61 patients with dementia (frontotemporal dementia, FTD, n = 33, and Alzheimer's disease, AD, n = 28) and 25 controls were included in the study. Results: ACE-IIIcognitive domains correlated significantly with standardised neuropsychological tests used in the assessment of attention, language, verbal memory and visuospatial function. The ACE-III also compared very favourably with its predecessor, the ACE-R, with similar levels of sensitivity and specificity. Conclusion: The results of this study provide objective validation of the ACE-III as a screening tool for cognitive deficits in FTD and AD.

          Distinguishing Subtypes in Primary Progressive Aphasia: Application of the Sydney Language Battery

          Background/Aims: Primary progressive aphasia (PPA) comprises three main subtypes, varying in clinical features, patterns of brain atrophy, and underlying pathology. Differentiation of these variants is important for treatment and planning; however, simple, effective cognitive tests to aid diagnosis are lacking. This study introduces a new language battery - the SYDBAT (Sydney Language Battery) - to assist clinicians. Methods: Fifty-seven PPA patients and 54 age- and education-matched healthy controls were compared on naming, repetition, word comprehension, and semantic association subtests. Results: Significant group differences were found for all tasks, reflecting different language profiles for each group. Using discriminative function analysis, 80% of PPA cases were correctly classified from three SYDBAT scores, from which a simple diagnostic algorithm was defined. Conclusion: The SYDBAT is a fast and simple tool which provides a valuable adjunct to clinicians diagnosing PPA.
