The 1968 Rechtschaffen and Kales (R & K) sleep scoring manual was published 15 years after REM sleep was discovered. Advances in the ensuing 28 years warranted a re-look at visual scoring of sleep stages. This paper describes the work of the AASM Visual Scoring Task Force, including methodology, a literature review and the rationale behind the new rules.(More)
We describe demographic, clinical, laboratory and aetiological findings in 93 consecutive patients with rapid eye movement (REM) sleep behaviour disorder (RBD), which consists of excessive motor activity during dreaming in association with loss of skeletal muscle atonia of REM sleep. The patients were seen at the Mayo Sleep Disorders Center between January(More)
STUDY OBJECTIVES To determine whether pramipexole used over an extended time for restless legs syndrome (RLS) remains effective; whether the dose of the drug needs to be increased; whether augmentation develops; and whether side effects, especially sleepiness, are prominent. DESIGN Retrospective review of the records of consecutive patients treated with(More)
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(More)
REM sleep behaviour disorder (RBD) is a parasomnia characterized by the loss of normal skeletal muscle atonia during REM sleep with prominent motor activity accompanying dreaming. The terminology relating to RBD, and mechanisms underlying REM sleep without atonia and RBD based on data in cat and rat are presented. Neuroimaging data from the few published(More)
STUDY OBJECTIVES To determine the age- and sex-specific incidence rates and prevalence of narcolepsy in a United States community. DESIGN The records-linkage system of the Rochester Epidemiology Project was utilized to ascertain all patients with narcolepsy seen in Olmsted County, Minnesota between 1960 and 1989. Age- and sex-specific incidence rates were(More)
OBJECTIVE To validate a questionnaire focused on rapid eye movement sleep (REM) sleep behavior disorder (RBD) among participants in an aging and dementia cohort. BACKGROUND RBD is a parasomnia that can develop in otherwise neurologically-normal adults as well as in those with a neurodegenerative disease. Confirmation of RBD requires polysomnography (PSG).(More)
Multiple system atrophy is characterized by autonomic failure along with motor symptoms of parkinsonism and/or cerebellar ataxia. There are differing reports on the influence of certain clinical features, including motor subtype (multiple system atrophy-parkinsonism versus multiple system atrophy-cerebellar ataxia), age of onset, gender, and early autonomic(More)
The management of sleep disturbances in patients with dementia is a complicated and enormously important clinical and societal problem. In this review, we present one approach to the diagnosis and management of such sleep disturbances. Most disturbances can be categorized into four primary symptoms: insomnia, hypersomnia, excessive nocturnal motor activity,(More)
A Task Force was established by the International Restless Legs Syndrome Study Group (IRLSSG) to develop evidence-based and consensus-based recommendations for the long-term pharmacologic treatment of restless legs syndrome/Willis-Ekbom disease (RLS/WED). The Task Force reviewed the results of all studies of RLS/WED treatments with durations of 6 months or(More)
