acting out dreams elderly

Schenck CH, Mahowald MW. Sleep talking can involve complicated dialogues or monologues, complete gibberish or mumbling. RBD is characterized as idiopathic (IRBD) if it occurs in the absence of another neurologic disease. JAMA Internal Medicine. Mirtazapine induces REM sleep behavior disorder (RBD) in parkinsonism. Manni R, Terzaghi M, Zambrelli E. REM sleep behaviour disorder in elderly subjects with epilepsy: frequency and clinical aspects of the comorbidity. In one case, the argument for causality was made even stronger by the fact that removal of the lesion (a neurinoma causing external compression of the pons) resulted in a resolution of RBD[70]. Bethesda, MD 20894, Web Policies REM sleep behavior disorder and degenerative dementia: an association likely reflecting Lewy body disease. The majority of enacted dreams have violent content and associated violent behaviors, although non-violent behaviours can also occur[1]. Review of EMG in 41 additional patients taking fluoxetine revealed increased muscle tone in REM in 15%, higher than would be expected in the unmedicated population (and higher than the rate in patients taking tricyclic antidepressants, in which it was seen in 4%)[96]. Insomnia, whether primary or secondary to coexistant illness or medication use, is very common among elderly people. Fortunately, during this phase of sleep the voluntary muscles are actively inhibited, which renders us incapable of acting out our dreams. 87% (of the 38 people for whom information was available); Worsening of pre-existing RBD or hyperactivity in REM, Opioid (with serotonin reuptake inhibition properties), Witnessed behaviors presumed by medical observer to be RBD, 0.254.0 mg nightly, with dosages 0.52.0 most commonly used, 3 mg starting dose, titrated to 12 mg as needed. There is a strong male predominance for RBD, with large case series reporting 8288% of RBD patients being male[79], and a recent review of 126 articles on RBD yielding a pooled male frequency of 73%[10]. Impact of anti-amyloid- monoclonal antibodies on the pathology and clinical profile of Alzheimer's disease: A focus on aducanumab and lecanemab. Women may have a later age of both onset and diagnosis[7]. Gagnon JF, Bedard MA, Fantini ML, et al. Wing YK, Lam SP, Li SX, et al. They may also exhibit recurrent agitated behaviour, known as sundowning, during which these patients are more confused, disoriented, suspicious and restless. Breathing disorders during sleep and cognitive performance in an older community sample: the EVA study. Graff-Radford J (expert opinion). This knowledge could potentially help with financial and other planning for subsequent years. All authors contributed content, made critical revisions, and have seen and approved the final version for publication. Larson EB. The prevalence of many sleep disorders increases with age. Violent behavior during sleep. Activation by selegiline (Eldepryle) of REM sleep behavior disorder in parkinsonism. Stiasny-Kolster K, Mayer G, Schafer S, et al. Accessed Feb. 11, 2021. The estimated prevalence in adults is 0.40.5%, but the frequency is much higher in certain neurodegenerative diseases, especially Parkinson's disease, Dementia with Lewy bodies, and multiple systems atrophy. Advertising revenue supports our not-for-profit mission. There are no published, double-blind, controlled, randomized trials of therapy for RBD[24, 106], and available therapies are `off-label' uses of medications approved for other indications. In several of these cases, the onset of RBD was temporally related to the onset of other focal neurologic symptoms and signs referable to the pons, suggesting that the lesion was also the cause of the RBD. However, the finding of decreased dopamine in patients with IRBD, who are at high risk of developing a neurodegenerative disease of the dopamine system, may be a marker of this impending neurodegeneration rather than the cause of the IRBD[14]. Alzheimer's and Dementia. The average number of apneas and hypopneas per hour is the apneahypopnea index, a useful gauge of the severity of this condition. Insights into REM sleep behavior disorder pathophysiology in brainstem-predominant Lewy body disease. These tend to be more noticeable than memory loss. Some treatable medical conditions can cause dementia symptoms, so it's important to determine the cause. Centers for Disease Control and Prevention. Older people seem to be more sensitive to these effects. In contrast to DLB, Alzheimer's disease (AD) does not appear to be commonly associated with RBD. Risk of ischemic heart disease in self-reported snorers. Narcolepsy in the older adult: epidemiology, diagnosis and management. REM sleep disorder is the acting out of dreams during the REM phase of sleep. Creuzfeldt-Jakob disease, classic (CJD): Occurrence and transmission. Sforza E, Krieger J, Petiau C. REM sleep behavior disorder: clinical and physiopathological findings. In a series of 15 AD patients, none had clinical symptoms of RBD, although one met PSG criteria and three additional had evidence of abnormal muscle tone during REM on PSG[61]. Accessed Feb. 8, 2021. Its prevalence increases with age; one study21 found the condition in 45% of a randomly selected sample of elderly subjects. Vorona RD, Ware JC. Bental E, Lavie P, Sharf B. Neuropsychological assessment in idiopathic REM sleep behavior disorder (RBD): does the idiopathic form of RBD really exist? Bedpartner input on these questionnaires was encouraged during the development process, and thus should also be used when applying these scales. RBD can be a risk factor for some brain diseases. Clonazepam is used as first-line therapy for RBD and melatonin for second-line therapy, although evidence for both of these interventions comes from uncontrolled case series. Mayo Clinic does not endorse companies or products. The .gov means its official. Rapid eye movement (REM) sleep behaviour disorder (RBD) is a sleep disorder in which patients appear to physically act out dreams during REM sleep. Sleep in spousal caregivers of people with Alzheimer's disease. . Kelly JF, Lowe DC, Taggart HM. Manni R, Terzaghi M, Zambrelli E. REM sleep behavior disorder and epileptic phenomena: clinical aspects of the comorbidity. privacy practices. Over the past several weeks, I've been filming myself sleep. Absence of alterations in serum sex hormone levels in idiopathic REM sleep behavior disorder. Twelve percent of epilepsy patients older than 60 years were confirmed to have RBD by PSG[79]. This recommendation is based on the results of three small case series of patients with idiopathic and secondary forms of RBD (totaling 35 patients, with a minority of patients on combination melatonin and clonazepam therapy). Alzheimer's Association. Unlike periodic leg movements, which awaken people from sleep, the symptoms of restless legs syndrome usually occur when patients get into bed, and thereby cause sleep-onset insomnia. Some research suggests that people with low levels of vitamin D in their blood are more likely to develop Alzheimer's disease and other forms of dementia. Treat high blood pressure, high cholesterol and diabetes. Response rates ranged from 7183%[111113]. Olfactory and color vision impairment are present in idiopathic RBD[3233]. As has been pointed out by other authors[2324], it is also plausible that RBD entails dreaming out actions, or that it is abnormal body movements that are triggered during REM and that specific dream content is then created around those actions. Dysfunction of brainstem regions implicated in the generation of REM atonia and suppression of locomotor generators is thought to underlie RBD pathophysiology. Doses range from 0.25 to 4.0 mg at bedtime, with dosages between 0.5 mg and 2.0 mg being most commonly used. Autonomic nervous system (ANS) abnormalities have also been demonstrated in IRB, including a lack of cardiac response to the transition from non-REM to REM sleep[34] and impairments in cardiac adrenergic function as measured by 123I-MIBG uptake[3538]. Such impulses often result in antisocial or delinquent behaviors. RBD associated with to Parkinson's disease (PD-RBD) is a common secondary form of RBD. Characteristics of RBD in large case series. Common in the general population, snoring is a frequent complaint of older people. https://www.alz.org/alzheimers-dementia/treatments/medications-for-memory. 2022; doi:10.1155/2022/9343514. Having memory loss alone doesn't mean you have dementia, although it's often one of the early signs of the condition. Donepezil, an acetylcholinesterase inhibitor, has been used in two small series of RBD patients. Snoring and myocardial infarction: a 4-year follow-up study. Department of Neurology, Emory University School of Medicine Atlanta, Georgia, USA, The publisher's final edited version of this article is available at. Federal government websites often end in .gov or .mil. The International Classification of Sleep Disorders. Common signs and symptoms include acting out one's dreams in sleep, seeing things that aren't there (visual hallucinations), and problems with focus and attention. the contents by NLM or the National Institutes of Health. FOIA (2023, May 25). 1998-2023 Mayo Foundation for Medical Education and Research (MFMER). Treatment of dementia. Side effects were mentioned in one series, and most commonly were morning sleepiness (13%) and morning headaches (13%), with any side effect occurring in 36%[113]. If we combine this information with your protected Elderly women tend to report sleep disturbances more frequently than elderly men. Schenck CH, Mahowald MW, Kim SW, et al. Manifestations of Parkinson disease differ in association with REM sleep behavior disorder. This is one of the more common types of progressive dementia. As a result, the prevalence rates found have varied widely. These dreams are often very vivid and can involve a wide range of movements . If you are a Mayo Clinic patient, this could Rapid-eye-movement sleep behavior disorder secondary to acute aseptic limbic encephalitis. Lai YY, Siegel JM. I-MIBG Cardiac Scintigraphy Provides clues to the underlying neurodegenerative disorder in idiopathic REM sleep behavior disorder. Olson EJ, Boeve BF, Silber MH. This syndrome is diagnosed with polysomnography by recording bursts of electromyographic activity that recur at regular periods in the affected muscles. Normal sleep progresses through several stages in a predictable fashion (Table 1). Pathophysiology of REM sleep behaviour disorder and relevance to neurodegenerative disease. The apparent decline in the incidence of snoring in the oldest cohorts could reflect a survivorship effect, if snoring is in fact related to other diseases and, ultimately, deaths among older people. 47.9% (composed of degenerative disorders in 23%, narcolepsy in 14%, other in 11%), 57% (47% PD, 13% dementia, 26% MSA, 8% narcolepsy, 2% PSP, 2% brainstem stroke), Comorbid or lifetime history of psychiatric disorders, Total 90.0% (79.1% complete, 11.1% partial). Because appropriate treatment of this disorder can be beneficial, accurate diagnosis is important. Normal sleep has 2 distinct stages: non- rapid eye movement (NREM) and rapid eye movement (REM) sleep. Older, community-dwelling people commonly undergo polypharmacy and receive inappropriate prescriptions from physicians,10 which unfortunately increases the possibility of insomnia related to medication use. Diagnosis of REM sleep behavior disorder by video-polysomnographic study: is one night enough? The frequent co-occurrence of RBD and PD, the prototypic disorder of dopamine loss, has led to speculation that RBD could be a hypo-dopaminergic disorder. Dementia symptoms vary depending on the cause, but common signs and symptoms include: See a doctor if you or a loved one has memory problems or other dementia symptoms. Treatment is purely symptomatic, and is generally recommended when there is significant risk of injury, troublesome dream content, or severe sleep disruption for the patient or bed-partner[14]. Brown A. Allscripts EPSi. Iranzo A, Santamaria J, Vilaseca I, et al. REM sleep behaviour disorder in Hong Kong Chinese: clinical outcome and gender comparison. The strongest predictor of whether a man is developing dementia with Lewy bodies is whether he acts out his dreams while sleeping. Mahowald MW, Schenck CH. Multiple systems atrophy (MSA), another neurodegenerative disease, is also strongly associated with RBD, with 70100% of MSA patients demonstrating symptoms of RBD and 90100% showing PSG evidence of RBD[6263]. Massicotte-Marquez J, Decary A, Gagnon JF, et al. Tips for communicating with a person with dementia. For caregivers, this behaviour is extremely disruptive, and often becomes the ultimate reason for admission of a patient with dementia to an institution. In keeping with this, patients with IRBD have measures of presynaptic dopamine transporter binding within the basal ganglia that are intermediate between those of normal controls and patients with PD[92]. Types of dementias that progress and aren't reversible include: Alzheimer's disease. In this important respiratory disorder, the upper airway is repeatedly obstructed during sleep, which reduces air flow (hypopnea) or stops it (apnea). This content does not have an Arabic version. Interestingly, McKibbon and colleagues8 also showed that elderly caregivers of patients with Alzheimer's disease reported more sleep problems and functional impairment from sleepiness than noncaregivers. Lewy body dementia is one of the most common causes of dementia. As a library, NLM provides access to scientific literature. Schenck CH, Mahowald MW. Bleeding between the surface of the brain and the covering over the brain, which is common in the elderly after a fall, can cause symptoms similar to those of dementia. Assessing whole brain perfusion changes in patients with REM sleep behavior disorder. Reduced striatal dopamine transporters in idiopathic rapid eye movement behaviour disorder. Non-pharmacologic treatments focused on ensuring nocturnal safety of the patient and bed-partner are also important. Perhaps the most conspicuously unexplained feature of RBD is the striking male predominance. Executive dysfunction and memory impairment in idiopathic REM sleep behavior disorder. The locomotor generators presumed to be disinhibited during RBD have not yet be clearly identified in humans[24], although these generators co-localize with the atonia centers in the pons in dogs[91], so this may also prove to be the case in human RBD. RBD may predate the onset of neurodegeneration by several years, with estimates of the five-year risk of developing a neurodegenerative condition after onset of RBD ranging from 18 to 45%. Dementia. Narcolepsy in the elderly: a forgotten diagnosis. When RBD co-exists with narcolepsy, this male predominance is not as pronounced[10]. All rights reserved. https://www.uptodate.com/contents/search. Elevated PEM (phasic electromyographic metric) rates identify rapid eye movement behavior disorder patients on nights without behavioral abnormalities. Feb. 10, 2021. CMAJ : Canadian Medical Association Journal, Sleep and aging: 2. The multiple sleep latency test in the diagnosis of narcolepsy [author reply: 2199]. It's where you act out your dreams. The behaviours may be simple or complex, including talking, singing, shouting, grabbing, strangulating, and jumping from the bed. This sleep problem is called REM sleep behavior disorder or RBD. Creutzfeldt-Jakob disease. Rapid eye movement (REM) sleep behaviour disorder (RBD) is a sleep disorder in which patients appear to physically act out dreams during REM sleep. Sleep talking, formally known as somniloquy, is a sleep disorder defined as talking during sleep without being aware of it. These conditions are often not appreciated by physicians, the associated symptoms ascribed instead to coexistant medical illness. Paroxysmal motor disorders of sleep: the clinical spectrum and differentiation from epilepsy. Onofrj M, Thomas A, D'Andreamatteo G, et al. Medications that can worsen memory. The syndrome can be asymptomatic and require no intercession. Other agents may be considered when clonazepam and melatonin are ineffective or contraindicated, although evidence supporting their use is very limited. Accessed Feb. 8, 2021. Plaques are clumps of a protein called beta-amyloid, and tangles are fibrous tangles made up of tau protein. When clonazepam is contraindicated, not successful or not tolerated, melatonin may be used as a second-line agent. Further, it is clear that not all PD patients develop RBD. You might expect that when someone sleep talks, they're acting out something that's unfolding in a dream they're having. Cataplexy attacks are usually triggered by an emotion, such as excitement, laughter, anger or surprise. The .gov means its official. Population-based estimates of RBD prevalence are 0.38% (among people aged 70 years or above in Hong Kong) to 0.5% (among non-institutionalized adults in the United Kingdom)[56]. Lewy body dementia. Restless legs syndrome in the older adult: diagnosis and management. In the United States, melatonin is not regulated by the Food and Drug Administration, so pill contents may not be standardized. This condition might be due to deposits of infectious proteins called prions. Age-related decline in muscle tone, which enhances upper-airway collapsibility, is another.40 Impaired pharyngeal sensory discrimination in older subjects also makes them more vulnerable to the occurrence and persistence of airway collapse during sleep.41, Epidemiological studies have suggested a relation of obstructive sleep apnea to hypertension, stroke and ischemic heart disease.42 These are thought to result, at least in part, from frequent intense sympathetic stimulation that occurs at the end of each obstructive phase. Schenck CH, Mahowald MW. Periodic limb movements in sleep in community-dwelling elderly. International Journal of Alzheimer's Disease. Evaluation of cognitive impairment of dementia. One study found a frequency of diagnosable mild cognitive impairment (MCI) of 50% in patients with IRBD versus 8% of healthy, similarly-aged controls[30]. Mild cognitive impairment in rapid eye movement sleep behavior disorder and Parkinson's disease. The most compelling data for a relationship comes from two series in which RBD started with the introduction of antidepressant medication and resolved after discontinuation, which has been shown in patients with IRBD as well as secondary forms[11, 98]. Several studies have found subtle cognitive abnormalities in this group of patients in domains of visuospatial function, verbal memory, attention, and executive functioning[2529]. Our landmark study is examining this connection and planning for Parkinson's prevention. Patients with IRBD by definition have no diagnosed co-morbid neurologic disease, yet this group of patients may not be neurologically normal. Miyamoto T, Miyamoto M, Suzuki K, et al. Postuma R, Lang A, Massicotte-Marquez J, et al. Zhang J, Lam SP, Ho CK, et al. You can get vitamin D through certain foods, supplements and sun exposure. Vascular involvement of the medulla has also been reported to result in RBD[77]. government site. Aggressive dream content without daytime aggressiveness in REM sleep behavior disorder. Prevalence and correlates of snoring and observed apneas in 5201 older adults. When such neuroprotective therapies become available, the development of idiopathic RBD may be a critical marker signaling the need for initiation of such therapy. Patients with Chiari malformations (type I or II)[83], Huntington's disease[84], spinocerebellar ataxia type 3[8586], and autism[87] all appear to have frequencies of RBD that are higher than would be expected based on population rates. . In patients with dementia and RBD, the most common form of dementia appears to be Dementia with Lewy Bodies (DLB). Medications reported to induce RBD or lack of normal muscle atonia during REM sleep. Doses ranged from 3 mg (the starting dose in all three series) to 12 mg, taken 30 minutes prior to bedtime. Acting out is a way of communicating what cannot be verbalized. This risk increased to 40.6% at 10 years and 52.4% at 12 years[89]. Alzheimer's disease drug development pipeline: 2022. Presynaptic striatal dopamine transporters (as shown by SPECT)[3940] and midbrain dopaminergic neurons (via PET)[41] are decreased in IRBD relative to control subjects. Symposium: Normal and abnormal REM sleep regulation: REM sleep behaviour disorder: an update on a series of 96 patients and a review of the world literature. National Library of Medicine Depending on the area of the brain that's damaged, dementia can affect people differently and cause different symptoms. Gagnon JF, Vendette M, Postuma RB, et al. RBD symptoms (not PSG-confirmed) have been reported in one pathologically-confirmed case of corticobasal ganglionic degeneration (CBD) (out of a series of 11 CBD patients)[67]. Common signs and symptoms include acting out one's dreams in sleep, seeing things that aren't there (visual hallucinations), and problems with focus and attention. Several authors have sought to explain the increased prevalence of this condition among older people. the unsubscribe link in the e-mail. Elderly women tend to report sleep disturbances more frequently than elderly men.4 The sleep changes noted among older women may be partly related to changes in the postmenopausal profile of sex hormones. This type of sleep apnea is also associated with the release of proinflammatory and prothrombotic factors important in the development of atherosclerosis.43. Postuma RB, Gagnon JF, Vendette M, et al. Kimura K, Tachibana N, Kohyama J, et al. Normally, dreaming occurs during REM sleep. Comparison with Parkinson's disease and controls. Parish JM, Somers VK. Rajput V, Bromley SM.,Chronic insomnia: a practical review. Cherniack NS, Longobardo G, Evangelista CJ. Make your tax-deductible gift and be a part of the cutting-edge research and care that's changing medicine. Though dementia generally involves memory loss, memory loss has different causes. Moreover, many sleep-related disorders occur with increasing frequency among elderly people. An important concept, especially for those who care for elderly people, is the notion that obstructive sleep apnea can contribute to cognitive impairment, which is likely related to frequent oxygen desaturation. Miyamoto T, Miyamoto M, Suzuki K, et al. Because of the high risk of both self-injury and bed-partner injury in RBD[8], preventive measures to improve the safety of the sleep environment are recommended to patients and spouses[109]. Frequent awakenings are particularly common among elderly people and may be related to their more frequent incidences of concurrent medical conditions. Kunz D, Bes F. Melatonin as a therapy in REM sleep behavior disorder patients: an open-labeled pilot study on the possible influence of melatonin on REM-sleep regulation. Moe KE. Restless legs syndrome is a distinct entity sometimes confused with periodic leg-movement disorder (Table 3). Six of 10 patients with parkinsonism due to PARKIN mutations (a condition in which synuclein aggregates are infrequently found in autopsy specimens) were found to have abnormal behaviors during REM sleep; a clinical history consistent with RBD was present 5 of these 6 patients[65]. Nash JR, Wilson SJ, Potokar JP, et al. . It has been proposed that melatonin may normalize the circadian timing of REM sleep and thus decrease RBD behaviors[112], but the mechanism of action of melatonin in RBD remains unknown. Drug treatment of REM sleep behavior disorders in dementia with Lewy bodies. "There's some evidence that, at times, sleep talking may be related to dreams, but this is not always the case," Dr. Drerup explains. Shneerson JM. It's a very common occurrence and is not. official website and that any information you provide is encrypted There is a problem with However, as it has not been reported to induce RBD and because of its non-serotonergic mechanism of action, it is considered by some authors to be the first-line antidepressant for patients with both depression and RBD. They include: Many factors can eventually contribute to dementia. This is particularly important in elderly patients who may, for physiologic reasons, be more susceptible to the stimulatory effects of these agents. The behaviors are typically violent, in association with violent dream content, so serious harm can be done to the patient or the bed-partner. Levodopa improved rapid eye movement sleep behavior disorder with diffuse Lewy body disease. https://www.nia.nih.gov/health/assessing-risk-alzheimers-disease. Anatomy of brainstem nuclei varies somewhat between species, and the exact nuclei involved in suppression of behaviour during REM sleep have not been conclusively identified in humans[24]. Hitting and yelling are the most common forms of acting out dreams, especially since the dreams are usually more like nightmares for dementia sufferers. Cerebral perfusion abnormalities may be seen in RBD, with perfusion increases in the pons, putamen, and right hippocampus and decreases in the frontal and temporoparietal regions[42]. If clonazepam is not effective, not tolerated, or contraindicated, melatonin can then be considered. Older patients who have had ischemic events involving the central nervous system may display frequent central sleep apnea with clinically significant nighttime oxygen desaturation.44, A distinctve form of central apnea is CheyneStokes respiration: it has a characteristic cyclic pattern of waxing and waning breaths with periods of complete cessation of breathing.45 CheyneStokes respiration is often seen in patients experiencing congestive heart failure.45. Jennum P, Hein HO, Suadicani P, et al. In addition to demonstrating the lack of REM atonia and potentially capturing dream-enactment behaviours during REM sleep, the PSG is helpful in excluding severe obstructive sleep apnea (OSA). Presentation of narcolepsy after 40. High blood pressure might lead to a higher risk of some types of dementia. Schenck CH, Bundlie SR, Mahowald MW. Koskenvuo M, Kaprio J, Telakivi T, et al. People with RBD describe having. Management of sleep disorders in older people. Among older patients with insomnia, however, the finding of periodic leg movements warrants treatment. Snoring as a risk factor for ischaemic heart disease and stroke in men. Some people act out their dreams while asleep. REM sleep behaviour disorder in Parkinson's disease is associated with specific motor features. My doctor suggested I write about my experiences as a coping mechanism, he said it would be appropriate to share with others and talk about it. 2022; doi:10.3389/fnagi.2022.870517. Lewy bodies are abnormal balloonlike clumps of protein that have been found in the brains of people with Lewy body dementia, Alzheimer's disease and Parkinson's disease. Levodopa shows similarly mixed results when used in PD-RBD. My doctor doesn't know all of what I'm about to tell you. Yamauchi K, Takehisa M, Tsuno M, et al. Try to avoid over-the-counter sleep aids that contain diphenhydramine (Advil PM, Aleve PM) and medications used to treat urinary urgency such as oxybutynin (Ditropan XL). Monane3 has estimated that insomnia affects nearly half of all those over the age of 65 years. Melatonin therapy for REM sleep behavior disorder. Estrogen deficiency in particular has been postulated to contribute to the sleep difficulties that women often begin to experience in their perimenopausal period, and then increasingly with age.5. Tan A, Salgado M, Fahn S. Rapid eye movement sleep behavior disorder preceding Parkinson's disease with therapeutic response to levodopa. Others may complain of severe fatigue or be observed to be excessively drowsy during the daytime. Although dream-enactment behaviours may not occur every night in all patients, a single night of video-PSG is sufficient for the diagnosis in the majority of cases[20] and increased phasic EMG activity may be useful to differentiate patients with RBD from elderly controls in the proper clinical context[21]. The REM sleep behavior disorder screening questionnaire: validation study of a Japanese version. Idiopathic rapid-eye-movement sleep disorder: associations with antidepressants, psychiatric diagnoses, and other factors, in relation to age of onset. In cats, pontine nuclei (locus coeruleus, pedunculopontine, laterodorsal tegmental) project to the medullary reticular formation, which in turn projects to the spinal cord to inhibit spinal motor neurons. Women may have higher density of EMG activity in the arms compared to men (who have higher density in the legs)[10], thus it is important to monitor both arm and leg EMG during diagnostic testing. In the forthcoming part 2, we will highlight the principles of treatment of these conditions. McKibbin CL, Ancoli-Israel S, Dimsdale J, et al. REM sleep behaviour disorder in Hong Kong Chinese: clinical outcome and gender comparison. Inclusion in an NLM database does not imply endorsement of, or agreement with, It is thought to be caused by a periodic cessation of respiratory drive. Culebras A, Moore JT. Lanfranchi P, Fradette L, Gagnon J, et al. Arnulf I, Nielsen J, Lohmann E, et al. Join PPMI today. Those with documented obstructive sleep apnea and daytime sleepiness are said to have obstructive sleep apnea syndrome, which is common in the general population. In part 1 of this review, we attempt to summarize several of the most important sleep-related disorders commonly observed in older patients. A chronic neurologic disorder of unclear origin, narcolepsy results in excessive daytime somnolence and fatigue.16 The main symptoms of this condition are sleep attacks, during which patients experience an irresistible urge to sleep (for a few minutes or up to an hour); hypnogogic hallucinations (extremely vivid auditory or visual hallucinations experienced while falling asleep or when waking up); sleep paralysis (a temporary inability to move upon wakening or before falling asleep); and cataplexy (a sudden, temporary, often unpredictable loss of muscle tone, which leads frequently to complete collapse).
