| Annotation | The relationship is examined between performance on neuropsychological tests and four instrumental activities of daily living (IADLs) associated with an increased risk of dementia in 1,792 non-demented older French people included in the Personnes Agées Quid (PAQUID) study. The four IADL items were use of the telephone, modes of transport, medication, and finances. There was decline in neuropsychological performance on each test with increasing IADL dependency, in particular between Grades 1 and 2. Performances of the independent participants were very homogeneous. Each IADL had different specific associations with the neuropsychological tests. A principal component analysis showed three main factors explaining 49.6% of variance. The first factor was the common cognitive component of both instrumental and neuropsychological tests. The second factor was specific to three IADLs, whereas use of transport had its main loading on the third factor. Only the first factor was predictive of the risk of incidental dementia, suggesting that the predictive value of the four IADLs was explained by their cognitive component. (RH). |
