Standardized diagnostic criteria determined by the International Restless Legs Syndrome Study Group were used to investigate the current prevalence of restless legs syndrome (RLS). Possible associations between RLS and neuropsychiatric and somatic complaints were also investigated. A random sample of 4,000 men living in central Sweden were sent a(More)

Restless legs syndrome (RLS) is a common neurological sensory-motor disorder that is characterized by intense restlessness and unpleasant creeping sensations deep inside the lower legs. Symptoms appear when the legs are at rest and are worst in the evening and at night. They force patients to keep moving their legs, and often to get out of bed and wander(More)
Iron deficiency may exacerbate symptoms in the Restless Legs Syndrome (RLS). We investigated the effect of intravenous iron sucrose or placebo on symptoms in patients with RLS and mild to moderate iron deficit. Sixty patients with primary RLS (seven males, age 46 (9) years, S-ferritin < or =45 microg/L) recruited from a cohort of 231 patients were randomly(More)
A random sample of 200 women, aged 18-64 years, living in a county in mid-Sweden, was sent a questionnaire that included questions about sleep habits, symptoms of sleepiness and neuropsychiatric complaints. Standardized diagnostic criteria determined by the International Restless Legs Syndrome Study Group were used to investigate the prevalence of restless(More)
BACKGROUND AND PURPOSE Restless legs syndrome (RLS) may be a cause of significant sleep disturbance. In a Swedish survey, the prevalence of RLS has been estimated to be 5.8% among men and 11.4% among women. Blood donation may result in iron deficiency, which is hypothesized to be one substantial cause of RLS. PATIENTS AND METHODS Nine hundred and(More)

OBJECTIVES Restless legs syndrome (RLS) is a common neurological movement disorder with a female preponderance and an increasing prevalence with age. During the menopausal transition, sleep is affected. Prior studies suggest that female hormones are associated with the clinical manifestation of RLS. METHODS A random sample of 5000 women aged 18-64 years(More)
