What is  Restless Leg Syndrome?

Restless leg syndrome, also referred to as Willis-Ekbom disease, is a condition that affects the nervous system and which causes various uncomfortable sensations and an uncontrollable urge to move the legs.

Symptoms of restless leg syndrome include:

  • Uncontrollable urge to move the legs
  • Uncomfortable sensations in the legs, such as: tingling, itching, burning or throbbing
  • Painful cramps in the legs, especially in the calves

The sensations can also affect the chest, arms, and face. They can be mild or severe, and are usually worse during the night and in the evening. Often times, these symptoms can be relieved by rubbing or moving the legs.

Some people experience them daily, while others only occasionally.

Who does it affect?

The condition can affect any person, although it is more common in women, and can present itself since childhood. The majority of cases are diagnosed in during midlife. Restless leg syndrome is also associated with involuntary jerking of the arms and legs during sleep, a condition known as periodic limb movements in sleep.

Possible Causes & Symptoms

Here are some of the most common causes and symptoms

Causes

Evidence suggests that restless leg syndrome occurs due to a problem in the basal ganglia. This is a region located in the brain that utilizes dopamine in order to adequately control movement and muscle activity.

If the cells within this region become damaged, dopamine levels in the brain drop, leading to muscle spasms and uncontrollable movements of the extremeties. At the end of the day, dopamine levels naturally fall, a particularity which may account for the fact that the symptoms of this condition worsen during the evening and at nighttime.

Symptoms

  • Uncontrollable urge to move the legs
  • Uncomfortable sensations in the legs, such as: tingling, itching, burning or throbbing
  • Painful cramps in the legs, especially in the calves

The sensations can also affect the chest, arms, and face. They can be mild or severe, and are usually worse during the night and in the evening. Often times, these symptoms can be relieved by rubbing or moving the legs.

Primary Restless Leg Syndrome

In the majority of cases, the exact cause of restless leg syndrome cannot be determined. This is called primary restless leg syndrome.

Research has linked this primary form to specific genes that can be transmitted from parents to children. In such cases the symptoms of restless leg syndrome appear before the age of 40.

Secondary Restless Leg Syndrome

Secondary restless leg syndrome is when the disease is caused by another underlying disease or health factor. 

  • Pregnancy – It tends to appear during the last trimester. The symptoms usually disappear a month after giving birth
  • Anemia caused by Iron Deficiency – Low Iron levels in the blood can cause low levels of dopamine, and subsequently restless leg syndrome
  • Chronic conditions: Diabetes, fibromyalgia, Parkinson’s Disease, Chronic Kidney Failure, Hypothyroidism
  • Chronic Venous Insufficiency – the symptoms of this disease often overlap and can be accompanied by those of restless leg syndrome

Triggers

The following are factors that can aggravate symptoms of restless leg syndrome

\

Medication

Certain antidepressants, antipsychotics, Lithium, Antihistamines, Metoclopramide. If you believe that your medication is aggravating your symptoms, do not stop taking them until you consult your physician about it.
\

Excessive intake of alcohol and caffeine

\

Excessive smoking

\

Obesity or being overweight

\

A sedentary lifestyle

\

Stress

Treatment

If the restless leg syndrome is caused by an underlying disease, treating that condition will also resolve the restless leg syndrome. In mild cases of restless leg syndrome that is not linked to any other medical condition, often times a few lifestyle changes will resolve or help manage the syndrome.

Lifestyle changes

Mild restless leg syndrome that isn’t linked to an underlying health condition can be managed with just a few lifestyle changes.

Possible solutions

  • Do not consume caffeine, alcohol or tabacco in the evening
  • Do not exercise close to bedtime
  • Quit smoking altogether
  • Exercise daily
  • Adopt and maintain good sleeping habits (going to bed and waking up at the same hour every day, meditate or relax before going to bed, do not watch TV before going to bed etc.)

Relieving symptoms

  • Massage the affected leg/legs
  • Take a hot bath
  • Apply a cold or hot compress to your affected leg
  • Do an activity that you enjoy and that keeps your mind occupied (reading, watching TV etc.)
  • Perform exercises that help you relax such as tai chi, yoga etc.
  • Stretch your legs or go out for a walk

Medication

If the symptoms are severe, appear often, cannot be controlled with a healthy lifestyle and affect the person’s quality of life, medication will be prescribed to control the condition.

\

Dopamine agonists

Such as Ropinirole, Pramipexole and Rotigotine, are prescribed for those that frequently experience symptoms of restless leg syndrome. They increase dopamine levels.

\

Painkillers

Light opiate-based painkillers, such as tramadol or codeine can be prescribed in order to lessen pain associated with restless legs syndrome.

\

Sleep aids

Shot-term courses if hypnotics such as Loprazolam or Temazepam can be prescribed to aid with sleep disruption caused by restless leg syndrome

\

Levodopa

Supplements your dopamine levels. Can be prescribed for those that suffer only occasionally from symptoms of restless leg syndrome

Work up

In order to rule out or confirm a possible underlying cause of restless leg syndrome some of the following tests might be required:

  • Blood tests (blood count, hemoglobin levels, iron levels, liver and kidney function studies, blood glucose, electrolytes et.)
  • Ultrasound to examine various organs, tissues and blood vessels (to rule out chronic venous insufficiency)
  • Electrocardiogram – those suffering from restless leg syndrome are more inclined to develop a cardiovascular condition
  • Sleep tests – recommended for those that have trouble sleeping in order to diagnose the presence of periodic limb movements in sleep
