Overview of Restless Legs Syndrome (RLS)
Restless Legs Syndrome (RLS) is a neurological disorder characterized by an uncontrollable urge to move the legs while resting or lying down. This condition is often accompanied by uncomfortable sensations such as tingling, burning, or itching. RLS primarily affects children and can significantly impact their quality of life, particularly their sleep. Understanding the causes, symptoms, and management options for RLS is crucial for providing effective support and care to affected children.
Definition
Restless Legs Syndrome (RLS) is defined as a condition in which individuals experience uncomfortable sensations and an uncontrollable urge to move their legs, especially when at rest. The symptoms typically worsen in the evening or when trying to sleep, leading to disrupted sleep patterns. RLS can vary in severity, with some children experiencing mild discomfort and others experiencing more severe symptoms that significantly affect their daily lives.
Prevalence
While Restless Legs Syndrome is often associated with adults, it is estimated that up to 2% of children also experience the condition. RLS can affect children of all ages, including infants. The prevalence of RLS is slightly higher in girls compared to boys. It is important to note that RLS in children may go undiagnosed or misdiagnosed due to the difficulty in communicating their symptoms effectively.
Symptoms
The symptoms of Restless Legs Syndrome in children can vary, but commonly include an irresistible urge to move the legs, accompanied by discomfort or unusual sensations. Children with RLS may describe these sensations as tingling, crawling, itching, or aching.
