Brain failure characterized by loss of ability to think, remember, reason, and communicate.

• A. Emesis
• B. Dementia
• C. Constipation
• D. Edema

Answer: (B)

Dementia is a decline in mental function caused by brain disease that affects multiple cognitive areas, including memory, thinking, reasoning, and language or communication. This combination of impaired memory and difficulties with thinking and talking is what characterizes dementia, and it typically persists and gradually worsens over time, interfering with daily life. The other options—vomiting, constipation, and edema—are medical issues of the digestive system or fluid balance and do not primarily involve cognitive decline or loss of memory and reasoning.
