What are the types of delirium?

The two types of delirium are:

• Hyperactive delirium: The person becomes overactive (agitated or restless).
• Hypoactive delirium: The person is underactive (sleepy and slow to respond).

Hypoactive delirium is more common, occurring in up to 75% of people with delirium. But many people, including healthcare providers, may incorrectly assume the person is depressed.

People can experience both types of delirium together. They can be extremely alert one minute and drowsy the next.
