What are the two types of delirium presentations?

• A. Hyperactive or hypoactive
• B. Acute or chronic
• C. Motor or sensory
• D. Confused or alert

Answer: (A)

Delirium is most often described by how the patient behaves in terms of activity level, giving two main presentations: hyperactive and hypoactive. In hyperactive delirium, there is marked agitation and increased motor activity—patients may be restless, restless, combative, or insistently trying to remove lines or devices, and they can have perceptual disturbances such as hallucinations. In hypoactive delirium, the patient is quiet, lethargic, slowed in movement and speech, and may appear withdrawn or depressed; this form is frequently overlooked because it doesn’t cause obvious agitation. Some patients cycle between both patterns or show features of each at different times. This distinction best captures how delirium presents clinically, focusing on observable behavioral and motor differences. Other categorizations don’t fit as well: delirium is an acute, fluctuating mental disturbance rather than a chronic state; categorizing by motor versus sensory or by level of confusion versus alertness doesn’t describe the typical presentation patterns as clearly as hyperactive and hypoactive do.
