What causes restless legs syndrome?
The cause of restless legs syndrome remains unknown. Restless legs syndrome is a central nervous system disorder. It is not caused by psychiatric factors or by stress but may contribute to or be exacerbated by these conditions. There is a high incidence of familial cases of restless legs syndrome, suggesting a genetic origin for primary restless legs
syndrome. estless legs syndrome runs in families in up to half of people with restless legs syndrome, especially if the condition started at an early age. Researchers have identified sites on the chromosomes where genes for restless legs syndrome may be present. Stress generally makes restless legs syndrome worse.
Pregnancy or hormonal changes may temporarily worsen restless legs syndrome signs and symptoms. Some pregnant women experience restless legs syndrome for the first time, especially during their last trimester. However, for most of these women, signs and symptoms usually disappear about a month after delivery. n some people with restless legs syndrome, anemia or vitamin deficiency may be a contributing factor, while in others restless legs syndrome has been linked to dabetes, rheumatoid arthritis, kidney failure, varicose veins or peripheral neuropathy (nerve damage in the hands and feet). High caffeine intake (coffee, tea, cola beverages, chocolate) also may be related to restless legs syndrome. Although restless legs syndrome tends to be more common and more severe in people over age 50, it can occur in men and women of any age group, even in young people who may be misdiagnosed as hyperactive.
Iron deficiency has been linked to restless legs syndrome in some people and may affect dopamine receptors in the brain. The body stores iron in the form of ferritin. There is a relationship between low levels of iron (as ferritin) stored in the body and the occurrence of restless legs syndrome.
