It has only been recently that we have become aware of the disorder called Restless Leg Syndrome. Though RLS was first listed in medical books around 1944, it has been known about for centuries and its cause is still a mystery.
Among the reasons and causes for RLS are a study released some years ago that stated adults with restless legs syndrome most likely also suffered from ADD or ADHD. RLS symptoms can cause burning, itching, crawling sensations and the victim feels the uncontrollable need to move to seek relief. In contrast, ADHD is characterized by restlessness, distractibility and impulsiveness – leading the study to find a large number of RLS patients also showed symptoms of ADHD.
Another theory for the causes of restless leg syndrome comes from results in Magnetic Resonance imaging (MRI) scans that show lower amounts of iron in the patient’s brains, when compared with patients who do not have RLS, again leading to the idea of a lack of dopamine in the brain.
Dopamine is made from iron which is carried to the nerve cells in the brain. Along this line, the explanation of restless leg syndrome can be related to other medical conditions including, iron deficiency also known as anemia, Peripheral neuropathy caused by damage to the nerves of arms and legs, diabetes, Parkinson’s disease, and restless leg syndrome is pregnancy is quite common. With treatment of these conditions, symptoms often improve or disappear completely.
RLS is known to be either a primary disorder or secondary condition, knowing the difference will help the doctor treat the symptoms and causes. By definition, primary RLS is often called “idiopathic,” meaning it has no real cause and is the most common. Secondary RLS is caused by an underlying condition.
Studies have also shown that certain medications/substances can also be a cause for RLS. Some secondary causes can include a magnesium deficiency, lack of vitamin B-12, Lyme disease, arthritis, lithium, and other similar prescriptions. Primary RLS, however, may be caused by the use of caffeine or alcohol , cigarettes as well as other lifestyle practices.
The result of these causes can lead to a moderate or severe RLS can be life changing with the person becoming totally disabled. To the extreme, those with RLS can not sit at work; continue to walk even while eating. Going to the movies, taking a trip in the car or a plane are often avoided. While RLS will not lead to other neurological conditions, it can get worse, leading to chronic fatigue syndrome and/or sleep disorders.
Treatment for restless legs syndrome consists mainly in the use of Mirapex and Requip together with other natural remedies as well as acupuncture.
