✦ Synopsis

One hundred and eight patients aged 70 and older randomly chosen from those admitted to the departments of medicine and surgery in a university hospital were examined for dementia by the Cambridge Mental Disorders of the Elderly Examination (CAMDEX) and DSM-111-R criteria. Cognitive impairment was assessed by the cognitive section of the CAMDEX (CAMCOG) and the Mini-Mental State Examination (MMSE). Fifty-one per cent of the sample met DSM-111-R criteria for at least one psychiatric disorder, dementia being the most common (35%). The cut-off point of CAMCOG (60/61) was more effective (100% sensitivity and 97% specificity) than the cut-off point of MMSE (21122) (95% sensitivity and 86% specificity) in detecting dementia, although the optimal cut-off point of CAMCOG for our sample was lower than that suggested in previous studies. KEY woms-dementia; CAMDEX; MMSE; elderly; medical inpatients Earlier studies have found high rates of psychiatric morbidity and cognitive impairment in medical inpatients (Canavaugh, 1983), particularly among the elderly (Johnston et al., 1987; Jorm et al., 1987); it is also known that the latter are referred less often for psychiatric consultation (Popkin et al., 1984). There is also evidence that hospitalization may cause further cognitive deterioration (McCartney and Palmateer, 1985). This suggests that further prospective assessments of psychiatric disorders and cognitive impairment in elderly inpatients are needed. Among the schedules developed for this purpose, the CAMDEX (Roth et al., 1986) seems to be one of the most reliable and useful. The aim of this study was to investigate the prevalence of dementia in elderly general hospital inpatients and examine their performance on the CAMCOG (the cognitive section of the CAMDEX) and the Mini-Mental State Examination (MMSE) (Folstein et al.,
