An algorithm for actigraphy-based sleep/wake scoring: Comparison with polysomnography.

Objective: To evaluate the accuracy of actigraphy against polysomnography (PSG) as gold standard using a newly developed algorithm for sleep/wake discrimination that explicitly models the temporal structure of sleep.

Methods: PSG was recorded in 11 men and 9 women (age 71.1±5.

Rating of daytime and nighttime symptoms in RLS: validation of the RLS-6 scale of restless legs syndrome/Willis-Ekbom disease.

Background: The International Restless Legs Scale (IRLS) is the most widely used of the scales rating the severity of restless legs syndrome/Willis-Ekbom disease (RLS/WED). It has been well validated and is the primary end point for most of the therapeutic and nontherapeutic studies of RLS/WED. It has excellent psychometric properties, although it does not capture the severity of RLS under a wide variety of circumstances and times of day.

Ropinirole improves depressive symptoms and restless legs syndrome severity in RLS patients: a multicentre, randomized, placebo-controlled study.

Comorbid depressive symptoms in restless legs syndrome (RLS) remain a treatment challenge, as some antidepressants aggravate RLS symptoms. Preliminary data in depressive patients suggest antidepressant properties of ropinirole. The present study investigates the effects of ropinirole immediate release (IR) on depressive symptoms and RLS severity.

Empirical evaluation of the accuracy of diagnostic criteria for Restless Legs Syndrome.

Background: In accordance with the diagnostic criteria of the International Restless Legs Syndrome (RLS) Study Group, the diagnosis of RLS is exclusively based on subjective information. Patients must report an urge to move the legs (and arms) with or without unpleasant sensations which is engendered by rest, relieved by movement, and worse in the evening or at night than during the day (essential criteria). Objective information such as excessive periodic leg movements, positive response to dopaminergic medication, family history of RLS or findings of a neurological examination cannot substitute any of the essential criteria but are considered both supportive for the RLS diagnosis and important for decisions on differential diagnoses.

Validation of an algorithm for the diagnosis of Restless Legs Syndrome: The Restless Legs Syndrome-Diagnostic Index (RLS-DI).

Background: There is a need for structured methods to improve sensitivity and specificity of diagnostic decision making in Restless Legs Syndrome (RLS). We present the RLS-Diagnostic Index (RLS-DI), a diagnostic algorithm which combines essential and supportive diagnostic criteria from patient interviews, polysomnography and neurological examination in an adaptive procedure.

Method: The RLS-DI consists of 10 items which are related to the essential diagnostic criteria established by the International RLS Study Group (five items) as well as their supportive criteria (3 items) and features associated with RLS (2 items).

Definition of restless legs syndrome, how to diagnose it, and how to differentiate it from RLS mimics.

Restless legs syndrome (RLS) is a clinical diagnosis based primarily on self-reports of individuals. The International RLS Study Group has published diagnostic criteria that are essential for an operational diagnosis of RLS; further clinical features are considered by the group supportive for or associated with RLS. However, sensitivity and specificity are not perfect and "mimics" of RLS have been reported, i.

Lisuride treatment of restless legs syndrome: first studies with monotherapy in de novo patients and in combination with levodopa in advanced disease.

In two 4-week polysomnography pilot studies with 10 patients each, we investigated the efficacy of oral lisuride as monotherapy in de novo RLS patients as well as in combination with levodopa in advanced RLS. Daily doses at study end were 0.3 mg lisuride, plus 150 mg levodopa in the combination study.

Transdermal lisuride: short-term efficacy and tolerability study in patients with severe restless legs syndrome.

Background And Purpose: Restless legs syndrome (RLS) patients suffer from symptoms not only at bedtime but also with variable circadian patterns. Transdermal application forms of dopamine agonists are expected to lead to a stable plasma concentration of the active drug which could ease treatment for RLS patients with daytime symptoms and avoid side effects of oral dopaminergic therapies.

Patients And Methods: In this controlled pilot study, 10 patients (six females, four males, mean age 58 years) with severe and long-lasting idiopathic RLS were treated during an initial open-label phase for 2 weeks either with one (n=3 patients) or, if required, two patches of lisuride every other day (dose per patch: 3mg lisuride, nominal effective release rate 7.
