Multiple Choice

Delirium is best described as:

Delirium is an acute disturbance of attention and awareness with cognitive changes that develop over hours to days and tend to fluctuate. It is often caused by an underlying medical issue, medications, infection, dehydration, metabolic problems, or withdrawal, and it is frequently reversible once the trigger is identified and treated. This contrasts with dementia, which is a chronic, progressive memory impairment without the same sudden fluctuation in consciousness. It also differs from a coma or persistent unresponsiveness, where consciousness is severely reduced or absent. While hallucinations can occur with delirium, it is not defined as a mood disorder; the defining feature is the sudden, reversible disturbance in consciousness and cognition rather than a primary mood disturbance.
