Persons with dementia frequently present behavioral and psychological symptoms as well as delirium. However, the association between these has received little attention from researchers and current knowledge in this area is limited. The purpose of this study was to examine the relation between delirium and behavioral symptoms of dementia (BSD). ⋯ Although correlates of BSD in persons with delirium superimposed on dementia are generally similar to those in persons with dementia alone, delirium is associated with a higher level of BSD. Results of this study have practical implications for the detection of delirium superimposed on dementia, the management of behavioral disturbances in patients with delirium, and caregiver burden.
