What is a characteristic symptom of restless legs syndrome (RLS)?

• A. Sleepwalking
• B. Intense itching in the legs
• C. Uncontrollable urges to move the legs
• D. Frequent night terrors

Answer: (C)

Restless Legs Syndrome (RLS) is primarily characterized by an overwhelming and uncontrollable urge to move the legs, typically due to uncomfortable sensations. This urge usually occurs when a person is at rest, such as during the evening or while sitting still, and is often relieved by movement, which distinguishes it from other conditions. Patients may describe the sensations as crawling, tingling, or an uncomfortable feeling in the legs, which compels them to get up and move around. The nature of RLS can significantly impact a person’s ability to relax or fall asleep, leading to sleep disturbances and daytime fatigue. Therefore, the characteristic symptom of uncontrollable urges to move the legs is central to the diagnosis and understanding of RLS, making it the correct choice in this context.
