Answer

Patients with delirium who are hyperactive have an increased state of arousal, psychomotor abnormalities, and hypervigilance. In contrast, patients with delirium who are hypoactive are withdrawn, less active, and sleepy.

Hypoactive delirium sometimes is misdiagnosed as dementia or depression.
