Diagnosing dementia: a comparison between a monodisciplinary and a multidisciplinary approach
Abstract
Discrepancies were examined in diagnostic outcome between a monodisciplinary approach and a multidisciplinary, criteria-based approach in patients referred to a university memory clinic. Of 278 patients not fulfilling dementia criteria, 19 had been previously diagnosed as demented (specificity: 0.93). In 60 of 152 demented patients, dementia had not been diagnosed before (sensitivity: 0.61). Underreporting was frequent for mildly demented patients and for patients with coexisting depressive symptoms. In patients referred by psychiatrists, sensitivity rates for dementia and Alzheimer's disease were low; in patients referred by neurologists, depression often went unreported. Results underscore the need for more frequent use of integrated multidisciplinary services for cognitively disturbed patients.
