841. Core and Suggestive Symptoms of Dementia with Lewy Bodies Cluster in Persons with Mild Dementia. (Abstract)

to classify persons into groups according to scores on scales for hallucinations, parkinsonism, fluctuations and REM sleep behaviour disorder (RBD).Four distinct clusters were revealed: a 'Lewy body dementia' (LBD) cluster with high scores for hallucinations, parkinsonism and fluctuation, and a 'non-LBD' cluster with low scores on all DLB symptom scales. In addition, 2 clusters with high scores on either RBD or cognitive fluctuation scales emerged. Persons in the LBD cluster had lower scores

843. Pilot Study of Melatonin and Epilepsy

to Brief Summary: The prevalence of epilepsy is 1% in the USA. About 30% of epilepsy patients eventually become refractory to medical treatment. Co morbid conditions are becoming as important as seizure control as these affect overall wellbeing. Sleep related complaints are frequent in them including, frequent arousals, difficulty falling asleep and excessive daytime sleepiness. Polysomnography shows increased arousal index, sleep onset latency, and stage shifts and fragmented REM sleep. Poor sleep (...) functioning, it is important to study effect of melatonin in children with epilepsy. We propose a randomized double blind placebo controlled trial with a cross-over design. Our hypothesis is that, for patients with epilepsy, administration of melatonin 30 minutes before bedtime for four weeks may: Improve the quality of sleep; Improve daytime functioning in terms of cognition, behavior and quality of life; Decrease epileptic potential. We will use polysomnography, electroencephalogram, psychomotor

853. Uncovering the Genetic Landscape for Multiple Sleep-Wake Traits Full Text available with Trip Pro

Uncovering the Genetic Landscape for Multiple Sleep-Wake Traits Despite decades of research in defining sleep-wake properties in mammals, little is known about the nature or identity of genes that regulate sleep, a fundamental behaviour that in humans occupies about one-third of the entire lifespan. While genome-wide association studies in humans and quantitative trait loci (QTL) analyses in mice have identified candidate genes for an increasing number of complex traits and genetic diseases (...) or dark period while some loci had opposite effects on the trait during the light vs. dark. Analysis of a dataset for multiple sleep-wake traits led to previously undetected interactions (including the differential genetic control of number and duration of REM bouts), as well as possible shared genetic regulatory mechanisms for seemingly different unrelated sleep-wake traits (e.g., number of arousals and REM latency). Construction of a Bayesian network for sleep-wake traits and loci led

854. Disappearance of “phantom limb” and amputated arm usage during dreaming in REM sleep behaviour disorder Full Text available with Trip Pro

Disappearance of “phantom limb” and amputated arm usage during dreaming in REM sleep behaviour disorder Limb amputation is followed, in approximately 90% of patients, by "phantom limb" sensations during wakefulness. When amputated patients dream, however, the phantom limb may be present all the time, part of the time, intermittently or not at all. Such dreaming experiences in amputees have usually been obtained only retrospectively in the morning and, moreover, dreaming is normally (...) associated with muscular atonia so the motor counterpart of the phantom limb experience cannot be observed directly. REM sleep behaviour disorder (RBD), in which muscle atonia is absent during REM sleep and patients act out their dreams, allows a more direct analysis of the "phantom limb" phenomena and their modifications during sleep.

Motor-Behavioral Episodes in REM Sleep Behavior Disorder and Phasic Events During REM Sleep To investigate if sudden-onset motor-behavioral episodes in REM sleep behavior disorder (RBD) are associated with phasic events of REM sleep, and to explore the potential meaning of such an association.Observational review analysis.Tertiary sleep center.Twelve individuals (11 males; mean age 67.6 +/- 7.4 years) affected by idiopathic RBD, displaying a total of 978 motor-behavioral episodes during (...) variable (REMs, STWs, alpha bursts) was associated more with purposefullsemi-purposeful than with primitive movements (P<0.05).Motor-behavioral episodes in RBD were significantly more likely to occur in association with phasic than with tonic periods of REM sleep. The presence of REMs, alpha bursts and STWs was found to be more frequent in more complex episodes. We hypothesize that motor-behavioral episodes in RBD are likely to occur when the brain, during REM sleep, is in a state of increased

856. Excessive Muscle Activity Increases Over Time in Idiopathic REM Sleep Behavior Disorder Full Text available with Trip Pro

Excessive Muscle Activity Increases Over Time in Idiopathic REM Sleep Behavior Disorder Rapid eye movement (REM) sleep behavior disorder (RBD) is characterized by excessive electromyographic (EMG) activity due to dysfunction of the brainstem structures modulating REM sleep atonia. Patients with idiopathic RBD often develop a neurodegenerative disease, such as Parkinson disease, over the years, suggesting progression of an underlying pathologic process in the brainstem. It is unknown (...) if the excessive EMG activity in REM sleep changes over time in patients with idiopathic RBD.University hospital sleep disorders center.Eleven patients with idiopathic RBD who were studied at baseline and after a mean follow-up of 5 years.NA.Eleven patients with idiopathic RBD underwent polysomnography (PSG) at the moment of the diagnosis of RBD (PSG1) and after a mean follow-up of 5 years (PSG2).

857. Idiopathic REM sleep behavior disorder in the transition to degenerative disease. (Abstract)

Idiopathic REM sleep behavior disorder in the transition to degenerative disease. Idiopathic REM sleep behavior disorder (RBD) predicts Parkinson's disease (PD) and dementia. However, the nature of the disease that emerges from RBD has not been fully characterized. Since 2004, we have been conducting a prospective study of idiopathic RBD patients, providing an opportunity to directly observe patients as they transitioned to a defined neurodegenerative syndrome. Patients with idiopathic RBD (...) underwent an extensive annual evaluation of motor function, olfaction, color vision, autonomic function, cognition and psychiatric symptoms. Neurodegenerative disease was defined according to standard criteria. We compared these measures in patients who had developed PD to those with dementia, all within the first year of developing disease. Of 67 patients, 6 developed PD and eleven developed dementia. Except for cognitive functioning, all tests of olfaction, color vision, autonomic function, depression

Midbrain hyperechogenicity in idiopathic REM sleep behavior disorder. Recent studies have reported an increased risk to develop Parkinson's disease (PD) in patients with idiopathic RBD (iRBD). Midbrain hyperechogenicity is a common transcranial sonography (TCS) finding in PD and has been suggested as a PD risk-marker in nonparkinsonian subjects. The objective of this study is to assess midbrain echogenicity by TCS in patients with iRBD and compare the findings with the healthy controls. TCS

859. Restless legs syndrome, rapid eye movement sleep behavior disorder, and hypersomnia in patients with two parkin mutations. (Abstract)

Restless legs syndrome, rapid eye movement sleep behavior disorder, and hypersomnia in patients with two parkin mutations. Parkin gene mutations cause a juvenile parkinsonism. Patients with these mutations may commonly exhibit REM sleep behaviour disorders, but other sleep problems (insomnia, sleepiness, restless legs syndrome) have not been studied. The aim of this study was to evaluate the sleep-wake phenotype in patients with two parkin mutations, compared with patients with idiopathic (...) group). Of the parkin patients, 45% had REM sleep without atonia, but only 9% had a definite REM sleep behavior disorder. All sleep measures were similar in the parkin and iPD groups. Two parkin siblings had a central hypersomnia, characterized by mean daytime sleep latencies of 3 min, no sleep onset REM periods, and normal nighttime sleep. Although the patients with two parkin mutations were young, their sleep phenotype paralleled the clinical and polygraphic sleep recording abnormalities reported

860. Complex dream-enacting behavior in sleepwalking. (Abstract)

Complex dream-enacting behavior in sleepwalking. Currently, dream-enacting behaviors are viewed as occurring typically in association with a REM-sleep behavior disorder. In some cases, dream-like mentation is found also in non-REM parasomnia.We report a case of complex and dramatic sleepwalking behavior in a 26-year-old adult male who tied his 4-month-old daughter to the clothesline in the attic of his house.The explanation of this seemingly senseless behavior, which was related to psychosocial (...) stressors, was found in a detailed dream-like mentation that was reported by the patient. At the same time, an organic factor, namely, a worsening of the patient's asthma, was identified as the cause of an increased fragmentation of sleep.In some cases of non-REM parasomnia, detailed dream-like mentation may act as a bridge between psychosocial stressors and the specific parasomnic behavior.
