Restless Legs Syndrome
topic
Restless Legs Syndrome (RLS) is a neurological sensorimotor disorder characterized by uncomfortable urges to move the legs — typically described as crawling, tingling, or burning sensations — that worsen at rest and in the evening and are temporarily relieved by movement, producing sleep-onset difficulty and sleep fragmentation. It affects approximately 7–10% of adults, with severity ranging from occasional mild annoyance to chronic daily debilitation, and is associated with iron deficiency, dopaminergic system dysfunction, and genetic susceptibility.
Role
RLS is one of the most frequently experienced and least frequently named sleep disorders — with many affected individuals attributing their pre-sleep discomfort to anxiety, poor circulation, or simple restlessness, never having encountered the clinical description that would identify their experience as a specific, treatable neurological condition. Iron supplementation (when ferritin levels are below optimal) produces significant symptom improvement in a substantial portion of RLS cases, making this one of the most straightforwardly treatable sleep disorders — yet most people experiencing it have never been evaluated for iron status in relation to their sleep symptoms.
