To analyze relationships between spouses' sleep problems and their partners' physical health, mental health, well-being, social involvement, and marital quality in a sample of older persons. ⋯ Although data are cross-sectional, findings suggest that spouses' sleep problems negatively impact partners' health and well-being. Our analyses emphasize the importance of treating sleep problems to promote the health and well-being of both affected individuals and their partners.

This paper reviews evidence from April, 1998 through April 2002 for the dopaminergic treatment of the restless legs syndrome (RLS) and periodic limb movement disorder (PLMD). There has been increased study of dopaminergic agents for the treatment of these conditions since publication of a review paper and practice parameters that covered all types of medical treatment of RLS and PLMD in 1999. For this reason, the Restless Legs Syndrome Task Force and the Standards of Practice Committee decided to update the evidence on dopaminergic treatment of these conditions. This paper reviews the literature on levodopa, dopaminergic agonists (pergolide, pramipexole, ropinirole, talipexole, cabergoline, piribidel, DHEC), and other dopaminergic agents (amantadine, selegiline).

Systematic interindividual differences in neurobehavioral impairment from sleep loss: evidence of trait-like differential vulnerability.
To investigate interindividual differences in neurobehavioral deficits during sleep deprivation, and to establish to what extent the neurobehavioral responses to sleep loss are a function of sleep history versus trait-like differential vulnerability. ⋯ Neurobehavioral deficits from sleep loss varied significantly among individuals and were stable within individuals. Interindividual differences in neurobehavioral responses to sleep deprivation were not merely a consequence of variations in sleep history. Rather, they involved trait-like differential vulnerability to impairment from sleep loss, for which neurobiologic correlates have yet to be discovered.

Peripheral arterial tonometry (PAT) is a sensitive measure of moment-to-moment changes in sympathetic activity and reliably identifies arousals in adult subjects. We investigated whether PAT events during sleep are associated with visually recognizable electroencephalographic arousals in healthy children and in children with sleep-disordered breathing. ⋯ Arousals in sleeping children are associated with increased sympathetic discharge, as evidenced by attenuations in PAT signal. However, a significant proportion of PAT attenuations were not accompanied by visual electroencephalographic arousals. Thus, the importance of these autonomic arousals has yet to be explored in association with morbidities related to sleep-disordered breathing and, therefore, PAT technology cannot be recommended as an alternative tool for measuring arousals in children. Nevertheless, these data further support the contention that adult criteria for the measurement for arousals may not be adequate in children.

The degree to which physical exercise habits are related to sleep-disordered breathing is not known. We sought to investigate the association between a single-item exercise question and laboratory-assessed sleep-disordered breathing. ⋯ Independent of measures of body habitus, lack of exercise was associated with increased severity of sleep-disordered breathing.
