Dementia is typically characterized by memory impairment that is:

• A. Gradual and progressive
• B. Rapid and reversible
• C. Sudden and complete
• D. Fluctuating and intermittent

Answer: (A)

Dementia shows a slow, ongoing decline in memory and other cognitive abilities. The impairment is insidious and progressive, meaning it worsens over months to years rather than appearing suddenly and reversing quickly. In the early stages, recent memory gaps and difficulty learning new information emerge, and over time daily functioning is affected as the decline continues. This pattern contrasts with delirium, where memory changes start abruptly, fluctuate, and are often reversible once the underlying cause is treated. So the typical description of dementia is a gradual and progressive memory impairment.
