Genetic testing for restless leg syndrome
Restless leg syndrome appears at rest and at night when people lie down to rest. During that time, they get an unpleasant feeling in the legs. It is compounded by kicking while sleeping which can be disturbing to the patient and his/her partner in bed alike. In Europe, restless leg syndrome affects around 10% of people; women are affected twice as commonly as men. The main cause of this syndrome has yet to be discovered. Some research indicates dopamine and iron deficiency in the brain.
Why should you have your DNA analysed for predisposition to the restless leg syndrome?
One half of all cases are characterized by a known family history. In the rest of the cases, genetic predisposition also plays a role. Three genes are known to cause an increased predisposition to the restless leg syndrome. These genes are included in our analysis. Knowing your genetic background reduces the need for, often unnecessary, additional check-ups.
How is restless leg syndrome prevented or treated?
Individuals suffering from this syndrome should avoid stimulants, tobacco and alcohol, and should undertake moderate physical activity which controls the symptoms. The drugs are used only for the most resistant cases with very frequent symptoms. The medications stimulate dopamine receptors in the brain.
