Delirium among patients with and without dementia: does the diagnosis according to the DSM-IV differ from the previous classifications?
Different diagnostic criteria differ in their capacity to identify subjects as delirious. It is not known how DSM-IV classification, compared with the DSM-III, DSM-III-R, and ICD-10, identifies delirium among individuals with and without dementia and whether the symptom profiles differ between these two subgroups. ⋯ DSM-IV criteria of delirium identify new, often non-demented, subjects as being delirious, while ICD-10 is overly restrictive. The symptom profile of delirium was slightly different among individuals with and without dementia.
