Sleep disturbances are common in patients with Parkinson's disease (PD). These disturbances can primarily affect the patient's quality of life and may worsen the symptoms of PD. Among the multiple sleep disturbances in PD patients, there has been a marked growing interest in rapid eye movement (REM) sleep behavior disorder (RBD). This is likely due to the fact that RBD has been proven to precede the motor symptoms of PD by many years. The aim of this article is to examine the sleep disturbances found in PD, with special attention to RBD as a premotor symptom of PD, as well as to assess its proposed related pathophysiology. MEDLINE (1966-March 2010), American Academy of Sleep Medicine's, The International Classification of Sleep Disorders, and current textbooks of sleep medicine were searched for relevant information. Search terms: RBD, sleep disturbances, Parkinson's disease, and pre-motor were used. Excessive daytime sleepiness (EDS), sleep attack, insomnia, restless leg syndrome (RLS), sleep-disordered breathing (SDB), and RBD are sleep disturbances commonly found in the literature related to PD. Sleep benefit has been proven to lessen PD motor symptoms. RBD has been described as a premotor symptom of PD in several prospective, retrospective, and cross-sectional studies. Sleep disturbances in PD can result secondarily to natural disease progression, as a side effect of the medications used in PD, or in result of pre-clinical pathology. Treatment of sleep disturbances in PD patients is crucial, as what is termed as, "sleep benefit effect" has been shown to improve the symptoms of PD.

Sleep disorders have been frequently reported in patients with Parkinson's disease (PD). However, there is insufficient evidence to guide precise recommendations on some diagnostic and treatment strategies. Here, we review clinical studies dealing with sleep abnormalities in PD and present clinical recommendations. Previous studies describing insomnia, excessive daytime sleepiness, narcolepsy-like episodes, circadian changes, sleep-disordered breathing, rapid eye movement sleep behavior disorder, vivid dreams and restless legs syndrome are evaluated. Longitudinal studies associating sleep disorders with PD onset or clinical deterioration are rare: only one longitudinal study associated daytime sleepiness with PD onset. Evidence suggests that clinical investigations must include direct questioning about depressive symptoms, nocturnal cramps, pain, nocturia and nighttime off periods. A patient interview must be conducted regarding sleep symptoms, including nightmares, abnormal behavior during sleep, snoring, restless legs syndrome and daytime sleepiness. Initial evidence indicates that light therapy improves motor function and depression. Advice on sleep hygiene, the treatment of concomitant depression and the careful use of dopaminergic drugs and hypnosedative agents should be considered. To date, very few controlled studies are available to make a recommendation for the management of sleep-wake disturbances in PD.

Sleep disturbances are among the most common disabling nonmotor symptoms of Parkinson disease (PD). Recently, awareness of sleep disorders related to PD has increased, reflecting their significant negative impact on the quality of life of the patient. However, sleep disturbances are still often under-recognized. In PD, multiple factors are associated with sleep disturbances; impaired arousal systems and sleep structure as disease-related changes, nocturnal motor symptoms, hallucinations and psychosis, pain, nocturia, depressive symptoms and dopaminergic medication can all cause insomnia. Further, these factors can coexist and influence each other during the course of the disease. In addition, sleep-related breathing disorder, restless legs syndrome (RLS) and rapid eye movement sleep behavior disorder (RBD) can also lead to impaired sleep. Some idiopathic RBD patients have been associated with a risk for developing neurodegenerative diseases, including PD. Therefore, early diagnosis of RBD may have significant clinical implications for neuroprotective strategies. Several studies have revealed an increased incidence of RLS in PD patients compared to the general population. The favorable responses to dopaminergic medications in treating both RLS and PD suggest shared pathophysiologies between the two diseases; however, neuroimaging studies of dopaminergic systems remain inconclusive. In this review, we discuss the current understanding of sleep disturbances in PD and the existing treatments.

Children with autism spectrum disorder demonstrate an increased prevalence of difficulties with sleep initiation and maintenance. The consequences may include alterations in daytime behavior, memory, and learning in patients, and significant stress in caretakers. The dysregulation of melatonin synthesis, sensitization to environmental stimuli, behavioral insomnia syndromes, delayed sleep phase syndrome, rapid eye movement sleep behavior disorder, and comorbid anxiety, depression, and epilepsy comprise common etiologic factors. The clinical assessment of sleep problems in this population and a management algorithm are presented.

Neurologists treat many people with unrecognized sleep disorders. This review recommends that new and established patients routinely complete standard sleep questionnaires as an aid to clinical history. Because there is high prevalence of treatable primary sleep disorders among neurologic patients, routine diagnostic sleep testing is indicated for patients with stroke, neuromuscular disease, dementia, REM behavioral disorder, atypical or treatment-refractory insomnia, and chronic and unexplained fatigue or sleepiness. As local and national regulatory momentum favors increasing care coordination and integration, neurologists should develop a clinical pathway to diagnose and treat sleep disorders within the practice or through a collegial expert network.

Sleep disturbances are among the most common nonmotor complaints of patients with Parkinson's disease (PD), and can have a great impact on quality of life. These disturbances manifest in a variety of ways; for instance, insomnia, sleep fragmentation, and excessive daytime sleepiness. Sleep-related movement disorders such as restless legs syndrome and periodic leg movements may share a common pathophysiology, and occurrence of rapid eye movement behavior disorder may predate the onset of PD or other synucleinopathies by several years. Medications for PD can have a significant impact on sleep, representing a great challenge to the treating physician. Awareness of the complex relationship between PD and sleep disorders, as well as the varied way in which sleep disturbances appear, is imperative for successful long-term management.

The development of new therapeutics for sleep disorders is increasingly dependent upon understanding the basic brain circuitry that underlies sleep-wake regulation, and how it may be pharmacologically manipulated. In this review, we consider the pathophysiological basis of major sleep disorders that often are seen by neurologists, including excessive daytime sleepiness, insomnia, narcolepsy, rapid eye movement sleep behavior disorder, and restless legs syndrome, as well as circadian disorders, and we review the current and potential future therapeutic approaches.

Sleep disorders are common in patients with Parkinson's disease (PD), and preliminary work has suggested viable treatment options for many of these disorders. For rapid eye movement sleep behavior disorder, melatonin and clonazepam are most commonly used, while rivastigmine might be a useful option in patients whose behaviors are refractory to the former. Optimal treatments for insomnia in PD have yet to be determined, but preliminary evidence suggests that cognitive-behavioral therapy, light therapy, eszopiclone, donepezil, and melatonin might be beneficial. Use of the wake-promoting agent modafinil results in significant improvement in subjective measures of excessive daytime sleepiness, but not of fatigue. Optimal treatment of restless legs syndrome and obstructive sleep apnea in PD are not yet established, although a trial of continuous positive airway pressure for sleep apnea was recently completed in PD patients. In those patients with early morning motor dysfunction and disrupted sleep, the rotigotine patch provides significant benefit.

Sleep disorders are commonly seen in atypical parkinsonism, with particular disorders occurring more frequently in specific parkinsonian disorders. Multiple systems atrophy (MSA) is a synucleinopathy often associated with nocturnal stridor which is a serious, but treatable condition highly specific to MSA. In addition, this disorder is strongly associated with rapid eye movement (REM) sleep behavior disorder (RBD), which is also seen in dementia with Lewy bodies (DLB). RBD is far less prevalent in progressive supranuclear palsy (PSP), which is a tauopathy. Insomnia and impaired sleep architecture are the most common sleep abnormalities seen in PSP. Corticobasilar degeneration (CBD) is also a tauopathy, but has far fewer sleep complaints associated with it than PSP. In this manuscript we review the spectrum of sleep dysfunction across the atypical parkinsonian disorders, emphasize the importance of evaluating for sleep disorders in patients with parkinsonian symptoms, and point to sleep characteristics that can provide diagnostic clues to the underlying parkinsonian disorder.

The aim of this study was to investigate and describe frequency and characteristics of sleep disorders in a large cohort of community dwelling persons with several degrees and typologies of cognitive disorders. 236 patients (78 men and 158 women) were enrolled with different subtypes of dementia: Alzheimer's disease (AD), vascular dementia (VaD), mixed dementia, mild cognitive impairment (MCI), dementia with Lewy bodies (DLB), parkinson's disease dementia (PDD), and frontotemporal lobar degeneration (FTLD), respectively. The sleep disturbances evaluated were: insomnia, excessive daytime sleepiness (EDS), REM behavior disorder (RBD), restless legs syndrome (RLS), and nightmares. Every type of sleep disorder was present in each type of dementia but with significant differences. Insomnia is found to be more present and specific for AD; EDS was associated with the presence of dementia in the elderly with LBD or PDD; RLS and nightmares that were recognized mainly in FTD, LBD, and PDD patients scores; patients with MCI had a frequency of sleep disturbances of any type equal to that of patients with AD presenting mostly insomnia, nightmares or RLS more frequently; nightmares were more frequent among LBD and PDD patients. Frequency of RDB was more frequent in FTD, AD, and VaD. Our findings demonstrate that sleep disturbance was related to dementia. A careful clinical evaluation of sleep disorders should be performed routinely in the clinical setting of persons with cognitive decline.
