Indices of neuropsychological functioning and decline over time in dementia

Analysis of performance on 22 neuropsychological tests in 58 patients with presumed dementia of the Alzheimer type and 58 with presumed multi-infarct dementia, and in subgroups reassessed 10 months later, provided useful indications of relative levels of success of various types of test as indices of neuropsychological functioning and decline over time in dementia. Short versions of the Token test were found to be amongst the best indices, and either can be recommended for inclusion in collections of tests used for clinical or research purposes in studies of dementia.
