Restless Leg Syndrome (RLS), also known as Willis-Ekbom Disease, is a common neurological disorder that affects millions of people in the United States. Characterized by an uncontrollable urge to move the legs, it is often accompanied by unpleasant sensations. RLS can significantly interfere with sleep, daily activities, and overall quality of life. At First Choice Neurology, our neurologists provide advanced diagnostic and treatment options for patients suffering from restless leg syndrome.
What Is Restless Leg Syndrome?
What Is Restless Leg Syndrome?Restless Leg Syndrome (RLS) is a neurological sensory condition that is classified as both a movement disorder and a sleep disorder. It is considered a movement disorder because symptoms improve with movement, such as walking or stretching. At the same time, it is recognized as a sleep disorder due to the way symptoms worsen at night and interfere with the ability to fall asleep or stay asleep.
Individuals with RLS often describe uncomfortable sensations such as tingling, throbbing, pulling, crawling, or aching deep within the legs. These sensations typically intensify during periods of rest or inactivity and become most noticeable in the evening or at bedtime. Because of this, RLS can significantly disrupt sleep and overall nighttime comfort. While the legs are most affected, RLS can also occur in the arms or other parts of the body in some cases.
Who Does RLS Affect?
Restless Leg Syndrome can affect all people, but research shows that it is more common in women. Hormonal factors, particularly during pregnancy, may play a role in the higher prevalence among women. RLS can occur at any age, including childhood, but symptoms tend to be more severe with increasing age. Many patients first notice mild symptoms in their 20s or 30s, which gradually worsen over time.
Genetics can also influence who develops RLS. Individuals with a family history of the disorder often experience symptoms earlier in life. Because it is both age and genetically influenced, RLS may appear spontaneously in adulthood or progress gradually over decades.
Symptoms of RLS
Restless Leg Syndrome symptoms may vary from mild to severe and can include:
• Uncomfortable sensations in the legs, often described as creeping, burning, itching, or pulling
• An irresistible urge to move the legs, especially during periods of rest
• Symptoms that worsen in the evening or at night
• Temporary relief with movement, such as stretching or walking
• Difficulty falling or staying asleep, which may lead to daytime fatigue
Because RLS disrupts sleep, it can contribute to mood changes, decrease concentration, and lower daytime energy levels.
What Causes Restless Leg Syndrome?
The exact cause of RLS is not fully understood, but neurologists believe that several factors may contribute to its development:
1. Dopamine Imbalance – The brain’s dopamine pathways play an important role in controlling movement. Disruption in this system may contribute to the symptoms of RLS, especially worsening at night, when dopamine levels naturally decline.
2. Genetics – Up to 50% of people with RLS have a family history of the condition. Genetic forms of RLS often begin before age 40 and progress slowly.
3. Iron Deficiency – Low iron levels in the brain may disrupt dopamine production. Even when blood levels appear normal, brain iron stores may be low in individuals with RLS.
4. Chronic Health Conditions – RLS is more common in people with:
• Diabetes
• Kidney disease
• Peripheral neuropathy
• Parkinson’s disease
• Multiple sclerosis
These conditions may affect nerve function, contributing to RLS symptoms.
5. Medications – Certain medications, such as some antihistamines, antidepressants, and antipsychotics, can worsen RLS symptoms.
6. Pregnancy – People often experience temporary RLS due to hormonal and iron level changes. Symptoms typically resolve after delivery.
How is RLS Diagnosed?
Diagnosis typically involves:
• A detailed medical history
• A neurological examination
• Reviewing sleep patterns and symptom triggers
• Blood tests to check for iron deficiency or underlying conditions
Because symptoms often occur during the night, some patients may undergo sleep studies if sleep disorders such as sleep apnea are suspected.
Is Restless Leg Syndrome a Sleep Disorder or a Movement Disorder?
Restless Leg Syndrome is unique because it falls into both categories. It is considered a movement disorder and a sleep disorder.
Since RLS directly impacts both movement pathways and sleep patterns, neurologists categorize it in a dual classification. It involves sensory discomfort, motor restlessness, and sleep disruption, making it a complex condition that requires evaluation and treatment from physicians who understand both neurological and sleep-related disorders.
RLS as a Movement Disorder
RLS is part of a broader group of neurological conditions known as movement disorders, which affect the speed, quality, or ease of movement. These may include Parkinson’s disease, dystonia, tremor, ataxia, and other disorders treated by movement disorder specialists. While many movement disorders involve involuntary or excessive movement, RLS is unique in that symptoms arise from an internal urge to move rather than involuntary actions.
RLS as a Sleep Disorder
Restless Leg Syndrome is also classified as a sleep disorder because symptoms typically worsen in the evening and can make it difficult to fall asleep or stay asleep. Many individuals with RLS experience periodic limb movements during sleep. They are brief, involuntary jerking or twitching of the legs, which further disrupts deep, restorative sleep. Over time, these sleep disturbances can lead to daytime fatigue, difficulty concentrating, irritability, and reduced quality of life. Managing RLS effectively is essential not only for relieving leg discomfort but also for improving overall sleep health.

Treatment Options for Restless Leg Syndrome
While there is no cure for RLS, effective treatments can significantly reduce symptoms and improve sleep. Treatment plans are individualized based on severity, underlying causes, and lifestyle factors.
1. Lifestyle Changes
• Maintaining a regular sleep schedule
• Reducing caffeine, alcohol, and nicotine
• Keep a diary of what you eat to discuss with your doctor
• Walking or stretching before bedtime
• Using warm baths or heating pads
These approaches can help with mild symptoms.
2. Iron Supplementation
If iron levels are low, supplements may help restore dopamine function and reduce symptoms.
3. Medications
Some Neurologists may prescribe:
• Alpha-2-delta calcium channel ligands (such as gabapentin or pregabalin)
• Iron infusions, when appropriate
• Medications for sleep, if insomnia is severe
• Dopamine agonists
4. Treating Underlying Conditions
Managing diabetes, kidney disease, neuropathy, or other disorders can reduce or eliminate RLS symptoms in many patients.
