OBJECTIVE To propose criteria for diagnosis of the night eating syndrome (NES). METHOD An international research meeting was held in April 2008, and consensus criteria for NES diagnosis were determined. RESULTS The core criterion is an abnormally increased food intake in the evening and nighttime, manifested by (1) consumption of at least 25% of intake(More)
IMPORTANCE The dream enactment of rapid eye movement sleep behavior disorder (RBD) is often the first indication of an impending α-synuclein disorder, such as Parkinson disease, multiple-system atrophy, or dementia with Lewy bodies. OBJECTIVE To provide an overview of RBD from the onset of dream enactment through the emergence of a parkinsonian disorder.(More)
Nighttime eating is categorized as either night eating syndrome (NES) or sleep-related eating disorder (SRED). These conditions represent an interruption in the overnight fast that characterizes human sleep. A critical review of the literature on NES and SRED will suggest that they are situated at opposite poles of a disordered eating spectrum. NES could be(More)
STUDY OBJECTIVES To determine the frequency of nocturnal eating (NE) and sleep related eating disorder (SRED) in restless legs syndrome (RLS) versus psychophysiological insomnia (INS), and the relationship of these conditions with dopaminergic and sedative-hypnotic medications. DESIGN Prospective case series. SETTING Sleep disorders center. PATIENTS(More)
BACKGROUND This study assessed the dimensional structure of sleep quality with the Pittsburgh Sleep Quality Index (PSQI) and investigated its psychometric properties in cases with temporomandibular disorders (TMD). METHODS A convenience sample of 609 TMD cases (age: 37.1 ± 13.1 yrs, 18-67 yrs, 85% female) of the multi-center Validation Project meeting(More)
The dominantly inherited spinocerebellar ataxias (SCA) are a clinically and genetically heterogeneous group of neurodegenerative disorders characterized by progressive gait ataxia, upper limb incoordination, and dysarthria. We studied a six-generation kindred of Norwegian ancestry with pure cerebellar ataxia inherited in an autosomal dominant pattern. All(More)
Parasomnias are abnormal behaviors emanating from or associated with sleep. Sleepwalking and related disorders result from an incomplete dissociation of wakefulness from nonrapid eye movement (NREM) sleep. Conditions that provoke repeated cortical arousals, or promote sleep inertia lead to NREM parasomnias by impairing normal arousal mechanisms. Changes in(More)
Identifying abnormal nocturnal eating is critically important for patient care and public health. Obesity is a global pandemic and a leading cause of preventable mortality in the United States, with more than 100,000 deaths annually. Normally, nighttime energy homeostasis is maintained, despite an absence of food intake, through appetite suppression and(More)
STUDY OBJECTIVES RBD may result in sleep related injury (SRI) particularly if a patient exits the bed during dream enactment behavior (DEB). The complex auditory processing and low arousal threshold of REM sleep offers a therapeutic window to halt behavior prior to SRI. We evaluated whether a recorded message prevents SRI in medically refractory RBD. (More)
To determine the frequency of subjective sleep problems in spinocerebellar ataxia type 6 (SCA6), the authors surveyed 25 patients and 25 age-matched controls with the Epworth Sleepiness Scale (ESS) and Pittsburgh Sleep Quality Index (PSQI). The ESS was higher in patients with SCA6 (9.12 +/- 5.80; CI: 2.28) than in controls (4.96 +/- 3.01; CI: 1.18) (p =(More)
