| Annotation | 253 consecutive discharged patients aged between 65 and 85 from 3 general hospitals in Munich, Germany were screened for cognitive impairment during their hospital stay. 4-6 weeks after discharge, each non-demented patient was visited at home and interviewed by a trained psychologist. The interview included a cognitive test battery incorporating the Clock Drawing Test (CDT), the Mini-Mental State Examination (MMSE), the Syndrome Short Test (SKT), and a verbal fluency test (VF). The criteria of the Clinical Dementing Rate (CDR) was used to differentiate between cognitively normal subjects and those with questionable dementia (QD). Assessment of agreement between raters found inter-rater reliability high on all scoring methods; and while substantial differences between scoring methods were observed, the CDT correlated significantly with MMSE, SKT and VF. However, the CDT lacks sufficient sensitivity and specificity for the identification of QD and should not be used alone to screen for possible prodromal stages of dementing illness. (RH). |
