Which term best describes a condition involving a significant decline in cognitive function such as memory and problem solving?

• A. Culture
• B. Death and dying
• C. Dementia
• D. Dehydration

Answer: (C)

A significant decline in cognitive function, including memory and problem solving, is best described by dementia. Dementia is a group of symptoms caused by brain disease that leads to a decline in mental abilities severe enough to interfere with daily life and independence. It’s not a normal part of aging, and it isn’t something that can be fixed by a quick change like hydration.

The other terms don’t fit this pattern: culture relates to shared beliefs and practices; death and dying concerns end-of-life topics; dehydration is a medical condition from fluid loss that can cause temporary confusion but does not describe a chronic, progressive cognitive disorder. Dementia, by contrast, captures the persistent and progressive nature of cognitive impairment.
