Many people have experienced a strange sensation in their legs just before going to sleep: a tingling, tingling or an urgent need to move them. For some, this happens occasionally and is of no great importance. For others, however, it becomes a recurring problem that directly affects their rest and well-being.

That irresistible urge to move your legs has a name: Restless Legs Syndrome (RLS)also known as Willis-Ekbom disease. It is a neurological sleep disorder which can go unnoticed for years, as many patients do not know they have it and think it is just "nervousness".

What exactly is Restless Legs Syndrome?

RLS is a disorder characterized by uncomfortable sensations in the lower extremities (although in some cases it also appears in arms), which generate an urgent need to move them to find relief.

The particularity is that:

• Symptoms appear at restwhen the person is sitting or lying down.
• Worsening in the afternoon or eveninginterfering with sleep onset and maintenance.
• Temporarily improve with movementfor example when standing up or stretching the legs.

👉 Unlike the insomniaRLS, which involves difficulty falling or staying asleep, manifests with physical restlessness that prevents relaxation and rest.

Characteristic symptoms of RLS

Although each person may describe it differently, most people agree on these sensations:

• Tingling, tingling or internal pressure in the legs.
• Mild pain or discomfort that is relieved only by moving.
• Jerking or involuntary movements during the night.
• Difficulty sleeping due to discomfort.
• Drowsiness and daytime tiredness as a consequence of lack of rest.

It is common for sufferers to describe it as "electric currents", "itching inside" or "bugs walking on the legs".

👉 These sensations can be confused with other sleep disturbances, such as the hypersomniawhere fatigue is constant, or with the parasomniaswhich also involve unusual nocturnal experiences.

Causes and risk factors

The exact causes of RLS are not known with certainty, but several related factors have been identified:

1. Neurological alterations
   • RLS appears to be linked to a malfunction in the regulation of dopamine, a neurotransmitter that controls muscle movements.
2. Iron deficiency
   • Even without anemia, an iron deficiency in the brain may contribute to the onset of symptoms.
3. Genetic predisposition
   • Up to 40% of RLS patients have a family history.
4. Associated chronic diseases
   • Renal insufficiency.
   • Diabetes.
   • Peripheral neuropathies.
5. Hormonal factors
   • During pregnancy, especially in the third trimester, many women develop RLS, although it usually subsides after delivery.

👉 This differentiates it from other disorders such as the. sleep apneawhere the main cause is obstruction of the respiratory tract.

Impact on daily life

RLS is not just a nocturnal disorder. Its effects extend into everyday life:

• Sleep disturbanceDifficulty in falling asleep and frequent awakenings.
• Daytime fatigue: reduction of work and academic performance.
• Emotional problemsanxiety, irritability and increased risk of depression.
• Impact on social lifeAvoid long trips or sedentary activities for fear of symptoms.

👉 As is the case with the. narcolepsyRLS can profoundly affect the daily routine and generate feelings of frustration.

Diagnosis: how to know if it is RLS

The diagnosis is usually based on a detailed clinical interview. The specialist will ask about:

• The frequency and intensity of symptoms.
• The time of day when they appear.
• Family history.
• Possible associated diseases.
