SIR—It is not widely appreciated, but up to half of all patients with restless leg syndrome can have unwanted movements and sensations in the upper extremities [1]. I give here a brief illustrative case history. An 88-year-old gentleman with restless leg syndrome diagnosed 3 years earlier presented complaining of being unable to sleep at night due to feelings of prickling and pain in both arms,...

OBJECTIVE There are no data adressing the prevalence of restless legs syndrome in subjects who have knee prosthesis. Therefore, we conducted a cross-sectional survey of subjects who underwent knee prosthesis surgery. METHOD A total of 107 subjects (30 male, 77 female) were interviewed over the telephone regarding restless legs syndrome symptoms. If the patients exhibited symptoms of the syndr...

The aim of this study was to determine balance problems and severity and ratio of postural instability of newly diagnosed, early stage Parkinson's patients who did not receive any antiparkinson treatment before, to evaluate fall risk clinically and posturographically and to examine the effects of pramipexole on these signs and symptoms. Detailed posturographic assessments which involved central...

Sleep-related eating disorder (SRED) is characterized by recurrent episodes of involuntary eating during sleep period and is often associated with restless legs syndrome (RLS). Although pharmacotherapy is recommended for SRED patients, no drug have shown promising effects so far. The patient, a 48-year-old Japanese housewife, first visited our clinic and complained about nighttime eating. She h...

The selectivity of inhibition for four dopamine receptor agonists (pramipexole, ropinirole, pergolide, and bromocriptine) on six human cytochrome P450 enzyme activities were evaluated using a simple in vitro inhibition screen. Drug-P450 interactions characterized as potent (i.e. greater than 50% inhibition of control enzyme activity) were then further examined to determine an IC50 for the inter...

The hippocampus has a significant association with memory, cognition and emotions. The dopaminergic projections from both the ventral tegmental area and substantia nigra are thought to be involved in hippocampal activity. To date, however, few studies have investigated dopaminergic innervation in the hippocampus or the functional consequences of reduced dopamine in disease models. Further compl...

BACKGROUND Since the publication of the first European Federation of Neurological Societies (EFNS) guidelines in 2005 on the management of restless legs syndrome (RLS; also known as Willis-Ekbom disease), there have been major therapeutic advances in the field. Furthermore, the management of RLS is now a part of routine neurological practice in Europe. New drugs have also become available, and ...

Background. This study's goal was to provide dose-response data for a dopamine agonist in the baboon using standard methods (replicate measurements at each dose, across a range of doses), as a standard against which to subsequently validate a novel pharmacological MRI (phMRI) method. Dependent variables were functional MRI (fMRI) data from brain regions selected a priori, and systemic prolactin...
