(Delirium is characterized by a change in cognition that occurs over a short period of time. It results from a secondary physiological condition (e.g., infection, surgery, prolonged hospitalization, hypoxia, fever, medications) and is a transient disorder. Although delirium can occur with any age, it is more common in older adults. It frequently progresses in the evening hours and is sometimes called "sundown syndrome." Delirium is characterized by alterations in memory, agitation, restlessness, illusions, or hallucinations. A client who becomes acutely confused and agitated may be showing manifestations of delirium.) A community health nurse is providing teaching to the family of a client who has primary dementia.
