[Screening for dementia: validity of the Cognitive Screening Test (CST) and the Mini-Mental State Examination].
The Cognitive Screening Test (CST--short version), a Dutch orientation questionnaire, and the Mini-Mental State Examination (MMSE) were compared with respect to their ability to discriminate between mildly demented, moderately demented and non-demented patients. The difference between mildly and moderately demented patients was based on the Global Deterioration Scale score. The CST and the MMSE were administered to patients who had been referred to the Memory Clinic of the University Hospital of Maastricht. Both instruments were successful in discriminating moderately and severely demented from non-demented patients. The CST and the MMSE were also successful with respect to the classification of depressive, non-demented elderly patients. The CST did not succeed in the correct classification of mildly demented patients (50% false-negative). The results of the MMSE in this group of mildly demented patients were moderate (25% false-negative). It is concluded that the value of both screening instruments, and especially the short version of the CST is limited for clinical practice.
