Which statement differentiates disease, disorder, and syndrome?

• A. A disease is a collection of symptoms.
• B. A disease is a harmful condition of the body; a disorder is a disturbance in health; a syndrome is a collection of symptoms.
• C. A syndrome is a disturbance in health.
• D. A syndrome is a harmful condition of the body.

Answer: (B)

Understanding how these terms differ helps in naming medical problems accurately. A disease is a harmful condition of the body that usually has an identifiable cause and underlying pathophysiology. It implies a specific process affecting structure or function. A disorder is any abnormality of function or health—it's a broad term for disruptions without requiring a defined disease mechanism. A syndrome, on the other hand, is a recognizable pattern composed of a set of signs and symptoms that tend to occur together, even if the exact cause isn’t fully known. The best statement captures these distinctions: a disease is a harmful condition of the body; a disorder is a disturbance in health; a syndrome is a collection of symptoms. The other options misdefine at least one term: a disease isn’t merely a collection of symptoms, a syndrome isn’t simply a disturbance in health, and a syndrome isn’t itself a harmful condition.
