A Review of Restless Leg Syndrome |
Restless Leg Syndrome (RLS), or Periodic Limb Movement Disorder,
causes an individual to have irritating sensations in the limbs, primarily
the legs, which are very distracting and uncomfortable, but usually not
painful. Patients describe the sensations as having itchy,
"creepy-crawly," or twitchy legs. The condition creates a need
for movement of the affected limb for temporary relief. Restless leg
syndrome was described as early as the 16th century but was not studied
until the 1940s. The exact cause of the problem is still unknown. RLS is
included in the sleep disorders since it causes periodic limb movements
and feelings of restlessness during the night. RLS symptoms increase
during times when a person is resting or sleeping. A RLS sufferer may be
partially or fully aroused from sleep from 5 to 50 times per hour. Even if
the individual is not awakened by the limb movements, this creates very
unhealthy, disjointed sleep and leads to fatigue during waking hours.
Symptoms of Restless Legs Syndrome:
The main symptom of RLS is an uncomfortable sensation in the legs. However
the sensation can also sometimes appear in the arms or trunk area.
These sensations have the following features:
- Occur most frequently during periods of inactivity, such as while
resting, sitting quietly or when attempting to fall asleep.
- Are temporarily relieved by movement of the limb.
- Can occur during the day, causing the individual to pace or move the
legs excessively.
- Cause involuntary jerking or twitching of the limbs during sleep.
- Cause excessive daytime fatigue or sleepiness caused by sleep
disturbances in the night, as well as insomnia.
What Causes RLS?
Currently, the cause for Restless Legs Syndrome is still unknown. However
it is known to have a strong genetic link and to be present in people with
other serious health problems, especially nerve damage disorders and poor
circulation.
Who is Affected by RLS Symptoms?
Restless leg syndrome is more common in:
- people who are over the age of 40.
- individuals who are under a great deal of stress.
- people with anemia, or a low red blood cell count. Anemia is often
caused by a low level of iron or folic acid in the diet.
- pregnant women, especially in the last trimester of pregnancy.
- people with peripheral nerve diseases, disorders that affect the
nerves that supply blood to the muscles and skin.
- people with poor circulation who have Claudication (intermittent
limping or leg pain that occurs when walking).
- people with various other health conditions, such as Parkinson's
disease, rheumatoid arthritis, chronic renal failure, diabetes, and
alcoholism.
How is RLS Diagnosed?
It is important to rule out the possibility that the symptoms of Restless
Legs Syndrome are not actually symptoms of a more serious problem like
nighttime seizures or neurological disorders. It is sometimes difficult to
determine whether uncomfortable limb sensations are caused by RLS, anemia,
poor circulation, nerve damage, or another disorder. Doctors diagnose RLS
by testing to preclude the existence of a more serious problem, studying
family health history, and by conducting thorough physical examinations of
the patient.
How is Restless Legs Syndrome Treated?
The treatment of RLS depends on what health problem is causing the
condition. Doctors may suggest treatment involving change of diet, stress
reduction, or medication, depending on the individual.
How Can You Get Relief from RLS?
Mild RLS sufferers may feel relief from their symptoms by:
- Exercising more frequently, as moving the legs usually relieves the
discomfort.
- Eating a healthy diet and getting enough Folic Acid, Calcium, Iron,
and essential vitamins.
- Reducing the amount of stress in their lifestyle. Popular relaxation
methods include exercise, hobbies, yoga, biofeedback, and meditation.
- Relieving physical symptoms using cold packs, massage, acupressure,
stretching, baths, or walking.
- Avoiding alcohol and caffeine-containing items like coffee, tea,
soda, and chocolate, especially later in the day.
- Maintaining a healthy sleep routine - sleeping in a quiet,
comfortable room, elevating the limbs with an adjustable
mattress, and going to bed and waking at the same times each day.
