The occurrence and duration of symptoms in elderly patients with delirium.
This study attempts to estimate the incidence, prevalence, and average duration of delirium in elderly patients; to assess the sensitivity of DSM-III and DSM-III-R in the diagnosis of delirium; and to compare the estimates of the duration of delirium using DSM-III and DSM-III-R criteria. ⋯ As operationalized in this study, DSM-III-R delirium criteria were more sensitive than DSM-III. Persistent symptoms are common in elderly patients with delirium.
