Dementia is most closely defined as:

• A. All of the above
• B. A result of ageing
• C. Declining language and memory
• D. The experience of confusion

Answer: (C)

Dementia is a chronic, progressive decline in cognitive function that interferes with daily life. The most characteristic features early on are problems with memory and language, making declining language and memory the best descriptor among the options. It’s not simply aging, since dementia represents a pathological change rather than a normal part of getting older. It isn’t defined by confusion alone—that describes delirium, which is acute and fluctuating, not the steady decline seen in dementia. So focusing on memory and language decline best captures the pattern clinicians look for when distinguishing dementia from normal aging and from delirium.
