Abstract

Objective Restless legs syndrome (RLS) is a distressing sensorimotor disorder with a 5% to 10% prevalence in the United States and Western Europe. The nocturnal occurrence of symptoms often leads to severe sleep disturbances. RLS has been reported to be associated with depression and anxiety. The aim of the present study was to investigate the relationship between RLS symptom severity, sleep disturbances, and depressive symptoms. Method Questionnaire data from 100 consecutive patients with idiopathic RLS who had been investigated in our Sleep Disorders Unit from April 1999 to December 2004 were evaluated. Patients were untreated regarding RLS, depression, or sleep disturbances. Severity of RLS was assessed with the International RLS Study Group rating scale (IRLS). Depressive symptoms and subjective sleep quality were determined using the Beck Depression Inventory (BDI) and the Pittsburgh Sleep Quality Index (PSQI), respectively. Results IRLS scores indicated moderate-to-severe RLS symptoms in the population studied (mean +/- SD IRLS score = 23.6 +/- 6.7). The mean +/- SD BDI score was 9.3 +/- 5.6, with highest values on the "reduced sleep," "loss of energy," and "work difficulties" items, indicating predominating somatic symptoms of depression. Fourteen patients had a BDI score of 15 to 20 ("mild depression"), and 3 patients had a BDI score of 20 to 30 ("mild to moderate depression"). Overall, patients estimated their sleep quality as moderately impaired (mean +/- SD PSQI sc…

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
