Chakraborty R, Biswas T, Mishra BR, Parmar A. Acute REM sleep behaviour disorder associated with alcohol withdrawal: A case report and literature review. Drug Alcohol Rev 2024; 43:760-763. [PMID: 38287722 DOI: 10.1111/dar.13809] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/17/2023] [Revised: 12/09/2023] [Accepted: 12/16/2023] [Indexed: 01/31/2024]
Abstract
INTRODUCTION Rapid eye movement (REM) sleep behaviour disorder (RBD) is a parasomnia characterised by the loss of REM sleep muscle atonia and the enactment of dreams. Acute RBD associated with alcohol withdrawal syndrome is known, but the studies are limited, particularly on its neurobiological underpinnings and management alongside the withdrawal state. This work attempts to address this using a case study and relevant literature review. CASE PRESENTATION A 40-year-old male with alcohol dependence (for 20 years) reported new-onset terrifying nightmares and violent behaviours in his sleep precipitated by alcohol withdrawal states for the last 18 months. The polysomnographic finding of REM-without-atonia supported the diagnosis of RBD. He was treated with chlordiazepoxide 100 mg/day (gradually tapered and stopped) and thiamine supplements. Post-discharge, he remained abstinent and symptom-free during the three months of follow-up. DISCUSSION RBD related to alcohol withdrawal syndrome has been previously described in a few anecdotal reports. Sudden withdrawal from central nervous system suppressants like alcohol is hypothesised to cause a homeostatic imbalance in gamma-aminobutyric acid (GABA) pathways and 'REM rebound', resulting in the clinical and polysomnographic picture of RBD. Benzodiazepines have been found to be useful in both RBD and alcohol withdrawal. CONCLUSIONS Alcohol withdrawal syndrome may present with acute RBD, which can be treated with a short course of benzodiazepine. However, further studies are needed to explore the long-term course of RBD in these patients.

Abstract
BACKGROUND The objectives of this review and meta-analysis of polysomnographic data are those to focus on the clinical use of clonazepam for the management of sleep disorders by re-analyzing clinical trials and randomized clinical trials which have been published in peer-reviewed journals. METHODS A review of the literature including clinical trials and randomized controlled trials was performed in PubMed®, in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement protocol. A random effects model meta-analysis was then carried out for the four more frequently reported polysomnographic measures: total sleep time, sleep latency, sleep efficiency, and periodic leg movement during sleep (PLMS) index. RESULTS A total of 33 articles were retrieved and screened in full text, of which 18 met the criteria for review; among the latter, nine met the criteria for meta-analysis. The studies included in the review involved patients with insomnia, REM sleep behavior disorder, sleep bruxism, and restless leg syndrome or PLMS which reported, most often, an increase in total sleep time with clonazepam. A clear sleep-promoting effect of clonazepam was found also by meta-analysis. DISCUSSION AND CONCLUSIONS Our results indicate that the pharmacological treatment of sleep disorders with clonazepam must always be personalized according to the type of patient, the risk of addiction and the concomitant presence of respiratory disorders are key factors to take into account. However, in light of the clinical evidence of the few studies in the literature on the different types of disorders, more studies on the use of clonazepam (also in association with first choice treatments) are definitely needed.

Abstract
Background
Sleep is essential for human health. Considerable effort has been put into academic and industrial research and in the development of wireless body area networks for sleep monitoring in terms of nonintrusiveness, portability, and autonomy. With the help of rapid advances in smart sensing and communication technologies, various sleep monitoring systems (hereafter, sleep monitoring systems) have been developed with advantages such as being low cost, accessible, discreet, contactless, unmanned, and suitable for long-term monitoring.
Objective
This paper aims to review current research in sleep monitoring to serve as a reference for researchers and to provide insights for future work. Specific selection criteria were chosen to include articles in which sleep monitoring systems or devices are covered.
Methods
This review investigates the use of various common sensors in the hardware implementation of current sleep monitoring systems as well as the types of parameters collected, their position in the body, the possible description of sleep phases, and the advantages and drawbacks. In addition, the data processing algorithms and software used in different studies on sleep monitoring systems and their results are presented. This review was not only limited to the study of laboratory research but also investigated the various popular commercial products available for sleep monitoring, presenting their characteristics, advantages, and disadvantages. In particular, we categorized existing research on sleep monitoring systems based on how the sensor is used, including the number and type of sensors, and the preferred position in the body. In addition to focusing on a specific system, issues concerning sleep monitoring systems such as privacy, economic, and social impact are also included. Finally, we presented an original sleep monitoring system solution developed in our laboratory.
Results
By retrieving a large number of articles and abstracts, we found that hotspot techniques such as big data, machine learning, artificial intelligence, and data mining have not been widely applied to the sleep monitoring research area. Accelerometers are the most commonly used sensor in sleep monitoring systems. Most commercial sleep monitoring products cannot provide performance evaluation based on gold standard polysomnography.
Conclusions
Combining hotspot techniques such as big data, machine learning, artificial intelligence, and data mining with sleep monitoring may be a promising research approach and will attract more researchers in the future. Balancing user acceptance and monitoring performance is the biggest challenge in sleep monitoring system research.

Acute levodopa dosing around-the-clock ameliorates REM sleep without atonia in hemiparkinsonian rats. NPJ PARKINSONS DISEASE 2019; 5:27. [PMID: 31815176 PMCID: PMC6884572 DOI: 10.1038/s41531-019-0096-2] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/15/2019] [Accepted: 10/21/2019] [Indexed: 01/08/2023]
Abstract
Rapid-eye-movement (REM) sleep without atonia (RSWA), a marker of REM sleep behavior disorder (RBD), is frequently comorbid with Parkinson's disease (PD). Although rodent models are commonly used for studying PD, the neurobiological and behavioral correlates of RBD remain poorly understood. Therefore, we developed a behavior-based criteria to identify RSWA in the hemiparkinsonian rat model of PD. Video recordings of rats were analyzed, to develop a criteria consisting of behavioral signs that occurred during polysomnographically confirmed epochs of sleep-wake stages. The sleep-slouch, a postural shift of the body or head caused only by gravity, was identified as a unique behavioral sign of REM sleep onset and was altered in hemiparkinsonian rats during RSWA. There was a significant correlation between the behavior-based criteria and polysomnograms for all sleep-wake stages in control but not hemiparkinsonian rats indicating a deterioration of sleep-wake architecture in parkinsonism. We then tested the efficacy of levodopa in ameliorating RSWA using intermittent and around-the-clock (ATC) dosing regimens. ATC levodopa dosing at 4 mg/kg for 48 h caused a significant reduction of RSWA as measured by polysomnography and the behavioral-based criteria along with an amelioration of forelimb motor deficits. Our findings show that the phenomenological correlates of RSWA can be reliably characterized in the hemiparkinsonian rat model. ATC levodopa administration ameliorates RSWA in this model without deleterious consequences to the overall sleep-wake architecture and therapeutic benefits for parkinsonian motor deficits. These findings suggest that further study may allow for the application of a similar approach to treat RBD in PD patients.

Abstract
Sleep is divided into two main sleep stages: (1) non-rapid eye movement sleep (non-REMS), characterized among others by reduced global brain activity; and (2) rapid eye movement sleep (REMS), characterized by global brain activity similar to that of wakefulness. Results of heart rate variability (HRV) analysis, which is widely used to explore autonomic modulation, have revealed higher parasympathetic tone during normal non-REMS and a shift toward sympathetic predominance during normal REMS. Moreover, HRV analysis combined with brain imaging has identified close connectivity between autonomic cardiac modulation and activity in brain areas such as the amygdala and insular cortex during REMS, but no connectivity between brain and cardiac activity during non-REMS. There is also some evidence for an association between HRV and dream intensity and emotionality. Following some technical considerations, this review addresses how brain activity during sleep contributes to changes in autonomic cardiac activity, organized into three parts: (1) the knowledge on autonomic cardiac control, (2) differences in brain and autonomic activity between non-REMS and REMS, and (3) the potential of HRV analysis to explore the sleeping brain, and the implications for psychiatric disorders.

Abstract
STUDY OBJECTIVES Sleep problems are a common phenomenon in most neurological and psychiatric diseases. In Parkinson disease (PD), for instance, sleep problems may be the most common and burdensome non-motor symptoms in addition to the well-described classical motor symptoms. Since sleep disturbances generally become apparent in the disease before motor symptoms emerge, they may represent early diagnostic tools and a means to investigate early mechanisms in PD onset. The sleep disturbance, REM sleep behavior disorder (RBD), precedes PD in one-third of patients. We therefore investigated sleep changes in marmoset monkeys treated with 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine hydrochloride (MPTP), the non-human primate model for idiopathic PD. DESIGN Mild parkinsonism was induced in 5 marmoset monkeys (3M/2F) over a 2-week period of subchronic MPTP treatment. Electroencephalograms (EEGs) and electromyograms (EMGs) were recorded weekly. Motor activity and hand-eye coordination were also measured weekly, and any signs of parkinsonism were noted each day. Sleep parameters, motor activity, and performance data before and after MPTP treatment were compared between MPTP-treated marmosets and 4 control marmosets (1M/3F). RESULTS MPTP increased the number of sleep epochs with high-amplitude EMG bouts during REM sleep relative to control animals (mean ± SEM percentage of REM 58.2 ± 9.3 vs. 29.6 ± 7.7; P < 0.05). Of all sleep parameters measured, RBD-like measures discriminated best between MPTP-treated and control animals. On the other hand, functional motor behavior, as measured by hand-eye coordination, was not affected by MPTP treatment (correct trials MPTP: 23.40 ± 3.56 vs. control: 36.13 ± 5.88 correct trials; P = 0.32). CONCLUSIONS This REM sleep-specific change, in the absence of profound changes in wake motor behaviors, suggests that the MPTP marmoset model of PD could be used for further studies into the mechanisms and treatment of RBD and other sleep disorders in premotor symptom PD.

Abstract
The aim of this review is to provide data on sleep disturbances in three categories of neurodegenerative disorders: synucleinopathies, tauopathies, and other diseases (this heterogeneous group includes also spinocerebellar degeneration and amyotrophic lateral sclerosis). Analysing and knowing sleep disorders in neurodegenerative diseases may offer important insights into the pathomechanism of some of these diseases and calls attention to the still insufficiently known 'sleep neurology'. The identification of sleep disorders in some neurodegenerative conditions may make their diagnosis easier and earlier; for example, rapid eye movements sleep behaviour disorder may precede any other clinical manifestation of synucleinopathies by more than 10 years.

Abstract
Fatigue is highly prevalent in multiple sclerosis (MS). It appears to be multifactorial, with "primary" or disease-related factors involved, as well as "secondary" factors, including comorbidities. Sleep disturbances are frequent in MS as well, and often result from disease-related factors. Subjective sleep disturbances in MS have been extensively studied and have been associated with fatigue. Sleep disorders in the general population have been associated with fatigue as well. However, data on objectively diagnosed sleep disorders in MS are less conclusive. Studies of sleep in MS have often suffered from low numbers of study subjects and suboptimal methodology. We review the current knowledge on sleep disturbances in MS and the relationship to fatigue. Data from neuroimaging studies and studies of molecular consequences of sleep disorders in the general population, with particular attention to sleep-disordered breathing (SDB), are briefly reviewed. Potential biologic interactions with MS are discussed in this context. We conclude that further studies of sleep disorders in MS are needed, to objectively establish their significance in this disease, and also to document any impact of treatment of sleep disorders on biologic and clinical outcomes such as fatigue.

Abstract
Sleep-related disorders are most prevalent in the older adult population. A high prevalence of medical and psychosocial comorbidities and the frequent use of multiple medications, rather than aging per se, are major reasons for this. A major concern, often underappreciated and underaddressed by clinicians, is the strong bidirectional relationship between sleep disorders and serious medical problems in older adults. Hypertension, depression, cardiovascular disease, and cerebrovascular disease are examples of diseases that are more likely to develop in individuals with sleep disorders. Conversely, individuals with any of these diseases are at a higher risk of developing sleep disorders. The goals of this article are to help guide clinicians in their general understanding of sleep problems in older persons, examine specific sleep disorders that occur in older persons, and suggest evidence- and expert-based recommendations for the assessment and treatment of sleep disorders in older persons. No such recommendations are available to help clinicians in their daily patient care practices. The four sections in the beginning of the article are titled, Background and Significance, General Review of Sleep, Recommendations Development, and General Approach to Detecting Sleep Disorders in an Ambulatory Setting. These are followed by overviews of specific sleep disorders: Insomnia, Sleep Apnea, Restless Legs Syndrome, Circadian Rhythm Sleep Disorders, Parasomnias, Hypersomnias, and Sleep Disorders in Long-Term Care Settings. Evidence- and expert- based recommendations, developed by a group of sleep and clinical experts, are presented after each sleep disorder.

Abstract
Sleep disorders are common and may result in significant morbidity. Examples of the major sleep disturbances in primary care practice include insomnia; sleep-disordered breathing, such as obstructive sleep apnea; central nervous system hypersomnias, including narcolepsy; circadian rhythm sleep disturbances; parasomnias, such as REM sleep behavior disorder; and sleep-related movement disorders, including restless legs syndrome. Diagnosis is based on meticulous inventory of the clinical history and careful physical examination. In some cases referral to a sleep laboratory for further evaluation with polysomnography, a sleep study, is indicated.

Abstract
A 9-month-old, female Labrador retriever mix was presented for two types of seizure-like episodes, one of which occurred only during sleep. The two types of episodes were morphologically distinct. An electroencephalogram (EEG) demonstrated that the sleep-associated episodes occurred during rapid eye movement (REM) sleep, supporting a diagnosis of a REM behavior disorder. Based on their morphology and response to antiseizure medications, the waking episodes were diagnosed as seizures. The animal was also diagnosed with an obsessive-compulsive and generalized anxiety disorder. The REM behavior disorder and anxiety-related behaviors improved with tricyclic antidepressant therapy.

Abstract
Following the decision in the Gillet Case it may no longer be safe to rely on the Austroads guidelines when considering fitness to drive. This paper examines the case and its implications. Although the Guidelines claimed '... the identification and application of world best-practice...', they were disregarded by the court in Gillet. Both expert witnesses testified that on disclosure of epilepsy the accused would have been endorsed as fit for a licence application to the Roads & Traffic Authority, on the basis of 10 years of only nocturnal seizures, in accordance with the guidelines. The Court rejected this evidence and interpreted failure to disclose epilepsy as recognition of perceived risk and the previously undiagnosed sleep apnoea as the basis for that risk, despite being diagnosed after the accident. There needs to be greater certainty in the application of the guidelines, with legislative intervention and licenses should display a bold statement advising drivers of their responsibility to notify authorities of illnesses that could potentially affect driving.

Abstract
OBJECTIVE To assess psychophysiological parameters in idiopathic rapid eye movements sleep behaviour disorder (RBD), in order to identify possible markers for pre or sub-clinical cognitive abnormalities. METHODS Sixteen consecutive unmedicated patients with idiopathic RBD and 16 age- and sex-matched controls performed active and passive auditory oddball paradigms and an attentional test. RESULTS There were no significant between-group latency and amplitude differences. The two groups showed a difference in the inter-peak interval between N100 and P200 in the active condition. A significant correlation between attentional matrices scores and N100 amplitude at Fz and Cz to standard stimuli in the passive condition was found in controls but not in patients. CONCLUSIONS In RBD there are minimal event-related potentials (ERPs) abnormalities involving the early stages of information processing. SIGNIFICANCE ERPs are not sensitive to pre or sub-clinical cognitive abnormalities in RBD. In alternative, these findings might support the existence of a truly idiopathic RBD syndrome.

Abstract
Parasomnias are common clinical complaints. Formal sleep evaluation including PSG is indicated for parasomnias that are violent and potentially injurious; disruptive to the bed partner or other household members; accompanied by excessive daytime sleepiness; or associated with medical,psychiatric, or neurologic symptoms or findings [2]. Multiple sleep latency testing should be considered for patients who have complaints of excessive daytime sleepiness. An extensive history, including medical, neurologic,psychiatric, and sleep disorder, and a review of medication, alcohol, illicit drug use, and family history of parasomnias, may provide useful clues. Distinguishing between a parasomnia and a seizure may be difficult as both can present as recurrent, stereotypical behaviors. Evaluation may be aided by an expanded EEG montage during overnight PSG studies.

Abstract
Sleep changes dramatically with old age. Subjective and objective measures demonstrate an increase in sleep and wake disturbances with advancing age. The older person has a more fragmented sleep, sleeps less deeply, and tends to experience early morning awakenings. When older patients have sleep disorders, they often present with excessive daytime sleepiness, insomnia, or abnormal motor activity. In making the appropriate diagnosis, the role of the provider is to review the patient's medical history,psychiatric history, medications, underlying medical illnesses, and sleep-wake pattern. The aging process itself does not cause sleep problems and sleep requirements do not decrease with advanced age. The prevalence of insomnia, sleep-related breathing disorder, PLMS, and RLS increases with age and may lead to poor sleep quality. Because many sleep disorders are potentially reversible, it is the responsibility of the primary care provider to screen for these problems. A carefully planned clinical decision-making process when encountering a sleep disturbance in the older patient can greatly enhance quality of life and daytime function.

Abstract
We reported previously that behavior suggestive of rapid eye movement sleep behavior disorder (RBD) was markedly increased in a small population of SCA-3 patients. We, therefore, asked patients and nonpatient attendees at an SCA-3 annual clinic to complete a questionnaire soliciting RBD-like behavior. Our results support the previous observation that RBD-like behaviors are significantly increased in SCA-3.

Abstract
The spectrum of rapid eye movement behavior disorders (RBD) spans various age groups, with the greatest prevalence in elderly men. Major diagnostic features include harmful or potentially harmful sleep behaviors that disrupt sleep continuity and dream enactment during rapid eye movement sleep. In RBD patients, the polysomnogram during rapid eye movement sleep demonstrates excessive augmentation of chin electromyogram or excessive chin or limb phasic electromyogram twitching. RBD may be associated with various neurodegenerative disorders, such as multiple system atrophy, Parkinson's disease, and dementia with Lewy bodies. Other co-morbid conditions may include narcolepsy, agrypnia excitata, sleepwalking, and sleep terrors. RBD is hypothesized to be caused by primary dysfunction of the pedunculo-pontine nucleus or other key brainstem structures associated with basal ganglia pathology or, alternatively, from abnormal afferent signals in the basal ganglia leading to dysfunction in the midbrain extrapyramidal area/ pedunculo-pontine nucleus regions.

Abstract
The present study was to determine how afferents from the substantia nigra pars reticulata (SNr) of the basal ganglia to the pedunculopontine tegmental nucleus (PPN) in the brainstem could contribute to the control of behavioral states. We used anesthetized and acutely decerebrated cats (n=22). Repetitive electrical stimulation (10-100 Hz, 20-50 microA, for 4-20 s) to the ventrolateral part of the PPN produced rapid eye movement (REM) associated with a suppression of postural muscle tone (REM with atonia). Although repetitive electrical stimuli (10-200 Hz, 10-60 microA, for 5-20 s) delivered to the dorsolateral part of the SNr did not evoke eye movements or muscular tonus in baseline conditions, it altered the PPN-induced REM with atonia. The following three types of effects were induced: (1) attenuation of the REM with atonia; (2) attenuation of muscular atonia without changes in REM (REM without atonia); and (3) attenuation of only REM. The optimal stimulus sites for these effects were intermingled within the lateral part of the SNr. The PPN-induced REM with atonia was abolished by an injection into the PPN of muscimol (1-15 mM, 0.1-0.25 microl), a GABAA receptor agonist, but not altered by an injection of baclofen (1-10 mM, 0.1-0.25 microl), a GABAB receptor agonist. Moreover, an injection of bicuculline (1-15 mM, 0.1-0.25 microl), a GABAA receptor antagonist, into the PPN, resulted in REM with atonia. On the other hand, an injection of muscimol into the dorsolateral part of the SNr (1-15 mM, 0.1-0.25 microl) induced REM with atonia, which was in turn eliminated by a further injection of muscimol into the PPN (5-10 mM, 0.2-0.25 microl). These results suggest that a GABAergic projection from the SNr to the PPN could be involved in the control of REM with atonia, signs which indicate REM sleep. An excessive GABAergic output from the basal ganglia to the PPN in parkinsonian patients may induce sleep disturbances, including a reduction of REM sleep periods and REM sleep behavioral disorders (REM without atonia).

Abstract
Idiopathic rapid eye movement (REM) sleep behavior disorder (RBD) is a parasomnia clinically linked with the alpha-synucleinopathies multiple systems atrophy (MSA), Parkinson's disease (PD), and dementia with Lewy bodies (DLB). Available autopsy information is limited but suggests that the pathologic basis of idiopathic RBD may be neuronal loss and Lewy bodies in pigmented monoaminergic nuclei, including the locus coeruleus and substantia nigra, which project to pontine nuclei mediating atonia during REM sleep. Thus, idiopathic RBD may be an alpha-synucleinopathy per se and a harbinger of impending PD, DLB, or MSA. Inclusion of historical or concurrent idiopathic RBD in the diagnostic criteria for DLB may improve their sensitivity, specificity, and clinical utility.

Abstract
The category of common sleep disorders known as parasomnias includes disorders of arousal, rapid eye movement (REM) sleep behaviour disorder (RBD), nocturnal seizures, rhythmic movement disorder, and tooth grinding or 'bruxism'. Parasomnias are all characterised as undesirable physical or behavioural phenomena occurring during the sleep period. Although these conditions can be distressing and, in some cases, hazardous to the sleeper and his or her bed partner, it is important to recognise that parasomnias are diagnosable and treatable in the vast majority of patients. Evaluation begins with a careful clinical interview with the sleeper and a family member to elucidate the frequency, duration, description and timing after sleep onset of these behavioural events. Disorders of arousal are the most common type of parasomnia and cover a spectrum from calm sleepwalking to emotionally agitated or complex behaviours, such as dressing or driving, for which the patient usually has no memory upon awaking. 'Sleep terrors' are quite common in young children and are often outgrown. Disorders of arousal represent a partial, as opposed to a full, awakening from deep non-REM sleep, typically occurring within the first 60 to 90 minutes after sleep onset. RBD is characterised clinically by a history of dream-enacting behaviour, and the patient may recall dream content. REM sleep periods typically occur in the latter half of the night. Physiologically, RBD results from a lack of the normal muscle atonia that is associated with REM sleep. RBD has been linked to a number of other neurological conditions; thus, a careful review of systems and a physical examination are crucial. A formal laboratory sleep study or polysomnogram with an expanded electroencephalographic montage can help distinguish among non-REM and REM parasomnias and nocturnal seizures. The latter may manifest clinically as arousals from sleep associated with vocalisation and/or complex behaviours. Rhythmic movement disorder can include head banging or body rocking at sleep onset or during the night. Tooth grinding is a common sleep-related behaviour that, when severe, can result in dental injury. Hypnagogic hallucinations (experience of dream imagery at sleep onset) and sleep-onset paralysis (experience of muscle/body paralysis as one is falling asleep) are symptoms rather than diagnostic categories. These phenomena classically occur in many individuals with narcolepsy, but also may occur in healthy sleep-deprived individuals. Safety precautions and good general sleep hygiene measures are recommended for individuals with a parasomnia, as the disorder can be exacerbated by sleep deprivation and various other factors. When the events are frequent or particularly dramatic, medication with a long- or medium-acting benzodiazepine, such as clonazepam, at bedtime is effective therapy in most cases of non-REM disorders of arousal and RBD. A dental guard may be helpful in tooth grinders. Relaxation training and guided imagery may be helpful strategies for some patients, especially those with disorders of arousal or rhythm movement disorders. There is no evidence of any association between parasomnias and psychiatric illness. Demystification of these conditions and reassurance, particularly for parents of paediatric patients, is an important aspect of clinical intervention.
