This project aims to develop comprehensive normative data for a number of neuropsychological tests of memory, attention and other cognitive abilities that are commonly used in the assessment and diagnosis of dementia and milder forms of cognitive impairment.
Normative data are used by psychologists and researchers to provide information about whether the individual being assessed is performing normally or not, on various tests. There are very little Australian normative data available and data derived from North American samples are typically used. Initial studies from the Sydney Memory and Ageing Study (MAS) suggest important differences exist in test performance of Australians and US normative groups which may affect diagnostic accuracy.
This project will develop local normative data from 1037 MAS participants who underwent a comprehensive battery of 12 neuropsychological tests measuring seven cognitive domains. These "norms" will be made available to clinicians and researchers and should improve practice. Applying standard normative data that are based on samples of native English speakers to persons of non-English speaking background may lead to misdiagnosis of cognitive impairment.
This project is investigating ways to improve diagnostic accuracy in persons of non-English speaking background by examining cultural, linguistic and educational factors that may influence cognitive performance. We have identified two main factors that influence performance:
