Elderly people often exhibit symptoms of delirium when admitted to the emergency room or during hospitalization. The causes of delirium are complex but are usually associated with advanced age, dementia and other cognitive conditions and illness. The most obvious symptom of delirium is a sudden change in cognitive functioning. A patient may lose the ability to recognize their close family members or recognize their surroundings.

Delirium can also be accompanied by aggressive or lethargic behaviors. Patients may also exhibit rapid mood changes, ranging from euphoria to intense agitation. These symptoms may appear and reside several times in 24 hours. Delirium in itself is considered an emergency and should be addressed by a medical professional.
