restless legs syndrome
A neurological disorder characterized by an irresistible urge to move the legs, typically accompanied by uncomfortable sensations.
Full Definition
A sensorimotor disorder that creates uncomfortable sensations in the legs and an overwhelming urge to move them, particularly during periods of rest or inactivity. Symptoms typically worsen in the evening and at night, significantly disrupting sleep onset and maintenance. The sensations are often described as crawling, creeping, pulling, or throbbing and are temporarily relieved by movement. RLS affects sleep quality and can lead to significant daytime fatigue and impairment. The condition is also known as Willis-Ekbom Disease and often coexists with periodic limb movement disorder.
