OBJECTIVE: Sleep is a complex neurologic process that is generated by and primarily benefits the brain. Sleep can be disrupted by a wide range of brain injuries, many of which may occur in children with neoplasms of the central nervous system (CNS). The specific sleep problems that have been associated with brain injuries include sleepiness, apnea, insomnia, and loss of circadian rhythmicity. The objective of this study was to characterize the sleep problems seen in children with ...

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 human cases with RBD associated with structural lesions in the brainstem are presented, in which the dorsal midbrain and pons are ...

STUDY OBJECTIVES: To formulate the first classification of sleep related disorders and abnormal sexual behaviors and experiences.

DESIGN: A computerized literature search was conducted, and other sources, such as textbooks, were searched.

RESULTS: Many categories of sleep related disorders were represented in the classification: parasomnias (confusional arousals/sleepwalking, with or without obstructive sleep apnea; REM sleep behavior disorder); sleep related seizures; Kleine-Levin ...

The clinical polysomnographic (PSG) reports of 2,650 consecutive adults studied during 41 months were reviewed retrospectively to identify all patients treated with fluoxetine or tricyclic antidepressants. The PSG reports of four other adult groups were also reviewed: periodic limb movement (PLM) disorder (n = 28); sleep terror/sleepwalking (ST/SW) (n = 54); rapid eye movement (REM) sleep behavior disorder (RBD) (n = 70); patients with clinically unremarkable sleep during two consecutive ...

OBJECTIVE: To determine if synucleinopathy pathology is related to REM sleep behavior disorder (RBD) plus dementia or parkinsonism.

METHODS: The clinical and neuropathologic findings were analyzed on all autopsied cases evaluated at Mayo Clinic Rochester from January 1990 to April 2002 who were diagnosed with RBD and a neurodegenerative disorder. Ubiquitin and/or alpha-synuclein immunocytochemistry was used in all cases. The clinical and neuropathologic diagnoses were based on published ...

Obstructive apneas and hypopneas during sleep are a well recognized cause of excessive daytime sleepiness. Snoring is also associated with excess sleepiness, although it is not known whether this reflects an independent effect of snoring or whether snoring is simply a marker for obstructive sleep apnea. To further explore the relation of snoring to sleepiness, we conducted a cross-sectional cohort study of community-dwelling adults participating in the Sleep Heart Health Study. The study ...

OBJECTIVE: To provide a 16-year update from the authors' 1996 report documenting a 38% conversion from idiopathic rapid eye movement sleep behavior disorder (iRBD) to a parkinsonian disorder at a mean interval of nearly 13 years after the onset of iRBD in a series of 29 males > or =50 years old.

METHODS: The methods of evaluation, diagnosis and follow-up were previously described in the 1996 report. All patients had video-polysomnography (vPSG) confirmed RBD.

RESULTS: 80.8% (21/26) of ...

Narcolepsy involves abnormalities of rapid-eye-movement (REM) sleep, including a short latency to the onset of REM sleep, hypnagogic hallucinations, and sleep paralysis. In addition, persistence of muscle tone by electromyographic criteria or excessive muscle twitching during REM sleep or both have been reported in treated and untreated narcoleptic patients. We report that another previously described abnormality of REM sleep, REM sleep behavior disorder, may also be a symptom of ...

We report longitudinal data on a group of 29 male patients 50 years of age or older who were initially diagnosed as having idiopathic REM sleep behavior disorder (RBD) after extensive polysomnographic and neurologic evaluations. Thirty-eight percent (11/29) were eventually diagnosed as having a parkinsonian disorder (presumably Parkinson's disease) at a mean interval of 3.7 +/- 1.4 (SD) years after the diagnosis of RBD+, and at a mean interval of 12.7 +/- 7.3 years after the onset of ...

A series of 33 patients with combined (injurious) sleepwalking, sleep terrors, and rapid eye movement (REM) sleep behavior disorder (viz. "parasomnia overlap disorder") was gathered over an 8-year period. Patients underwent clinical and polysomnographic evaluations. Mean age was 34 +/- 14 (SD) years; mean age of parasomnia onset was 15 +/- 16 years (range 1-66); 70% (n = 23) were males. An idiopathic subgroup (n = 22) had a significantly earlier mean age of parasomnia onset (9 +/- 7 ...

Four men, aged 67-72 years, had 4-month to 6-year histories of injuring themselves or their spouses with aggressive behaviors during sleep, often during attempted dream enactment. A 60-year-old woman had disruptive though nonviolent sleep and dream behaviors. Polysomnography did not detect seizures but did document REM sleep pathology with variable loss of chin atonia, extraordinarily increased limb-twitch activity, and increased REM ocular activity and density. A broad range of REM ...

Over a 5-yr period, 19 adults presented to our sleep disorders center with histories of involuntary, nocturnal, sleep-related eating that usually occurred with other problematic nocturnal behaviors. Mean age (+/- SD) at presentation was 37.4 (+/- 9.1) yr (range 18-54); 73.7% of the patients (n = 14) were female. Mean age of sleep-related eating onset was 24.7 (+/- 12.9) yr (range 5-44). Eating occurred from sleep nightly in 57.9% (n = 11) of patients. Chief complaints included excessive ...

Parasomnias are defined

in the International Classification

of Sleep Disorders-2nd

Edition (ICSD-2) as undesirable

physical events or experiences that

occur during entry into sleep,

within sleep, or during arousals

from sleep. Instinctual behaviors

can inappropriately emerge with

the parasomnias, including appetite

behaviors (feeding, sex), locomotion,

aggression, and violence.

Sleep disorders and their therapies

carry their own risk for parasomnias,

including sleep-disordered

breathing ...
