Restless Legs Syndrome: Symptoms, Causes & Treatment
متلازمة Restless Legs
Restless legs syndrome is a neurological disorder causing an irresistible urge to move the legs with an uncomfortable sensation that worsens at rest and in the evening and eases with movement, disrupting sleep. It is sometimes linked to iron deficiency. It is managed by treating the cause, lifestyle changes, and medication when needed.
What is Restless Legs Syndrome?
Restless legs syndrome is a chronic sensorimotor neurological disorder characterized by a strong, irresistible urge to move the legs, accompanied by uncomfortable, unpleasant sensations deep in the legs that patients describe as crawling, tingling, pulling, or burning. It is a common condition that is often misunderstood or undiagnosed.
What distinguishes this syndrome is its clear time pattern: symptoms appear or intensify during rest and stillness (such as sitting or lying down), worsen in the evening and at night, and ease or temporarily disappear with movement such as walking or moving the legs. This pattern is why it greatly affects sleep, as the patient finds it hard to fall asleep or wakes because of the need to move their legs, leading to insomnia and daytime fatigue.
Restless legs syndrome may be primary (without a clear cause and often with a family history) or secondary, linked to other conditions, most importantly iron deficiency and its stores (ferritin), in addition to pregnancy, kidney failure, and some medications. One of the most important evaluation steps is therefore checking iron stores, because replacing it may greatly improve symptoms. Management includes treating the treatable cause, lifestyle changes (reducing caffeine, moderate exercise, regular sleep), and specialized medications prescribed by the doctor in cases affecting quality of life.

- Iron deficiency and its stores (ferritin).
- Pregnancy and kidney failure.
- Some medications and neurological conditions.
Diagnosis
- Clinical diagnosis based on the characteristic symptom pattern.
- An iron-stores (ferritin) test, an important step.
- Assessing other secondary causes.
Treatment
Treating the cause
- Replacing iron when stores are low may greatly improve symptoms.
- Reviewing causative medications and treating accompanying conditions.
