[Development and validation of a test for early diagnosis of dementia with differentiation from depression (TFDD)].

Psychometric tests used for the early detection of dementia often are seen as too difficult or too complex. Classical neuropsychologic tests were not developed for this purpose. Sensitivity and specificity to discriminate "healthy" vs.

A comparison of ADAS and EEG in the discrimination of patients with dementia of the Alzheimer type from healthy controls.

Neuropsychometric tests (for instance the Alzheimer's Disease Assessment Scale, ADAS) and the EEG are often used in the diagnostic procedure of dementia. The validity of the instruments is only poorly investigated. The study aimed to investigate the accuracy of the discrimination between healthy controls and patients with dementia of the Alzheimer type (DAT) by ADAS and EEG.

Neuropsychometric tests in cross sectional and longitudinal studies - a regression analysis of ADAS - cog, SKT and MMSE.

Introduction: In clinical and drug studies, different neuropsychometric tests are used. So far, no empirical data have been published to compare studies using different tests. The purpose of this study was to calculate a regression formula allowing a comparison of cross-sectional and longitudinal data from three neuropsychometric tests that are frequently used in drug studies (Alzheimer's Disease Assessment Scale, ADAS-cog; Syndrom Kurz Test, SKT; Mini Mental State Examination, MMSE).
