Altered sleep is a common non motor symptom in Parkinson's disease. Sleep dysfunction has been reported to occur in 60-90% of all PD patients, having a detrimental impact on quality of life and increasing disability. alpha-Synuclein deposits in the lower brainstem affecting autonomic and sleep regions have been identified in the pathophysiology. The resultant non motor symptoms such as REM sleep behaviour disorder (RBD) can precede the motor symptoms by years. RBD is violent, enacted dreams that expose the patient or their sleeping partner to night-time injuries. Excessive daytime sleepiness, sometimes with a narcolepsy-like phenotype, is a common occurrence in PD, owing to lesions in the arousal systems of the brain. Restless legs syndrome and sleep disordered breathing can all affect daytime alertness of PD patients. Autonomic deregulation can also negatively affect sleep patterns, by adding to night-time wakening and disrupting sleep.

This paper reviews the characteristics of sleep disorders found in people at a greater risk of dementia: the elderly adult, patients with mild cognitive impairment (MCI) and those with neurodegenerative diseases. The frequency of sleep architecture modifications and circadian rhythm sleep disturbances increases with age. Although around 40% of older adults complain of poor sleep, true sleep disorders are far less prevalent in healthy older adults and are frequently associated with comorbidities. The sleep disorders observed in Alzheimer's disease (AD) patients are often similar to (but more intense than) those found in non-demented elderly people. Poor sleep results in an increased risk of significant morbidities and even mortality in demented patients and constitutes a major source of stress for caregivers. The prevalence of primary sleep disorders such as rapid eye movement (REM) sleep behavior disorders (RBDs), restless legs syndrome (RLS), periodic limb movements (PLMs) and sleep-disordered breathing increases with age. There are no published data on RLS and PLMs in demented persons but RBDs and sleep apnea syndrome have been studied more extensively. In fact, RBDs are suggestive of Lewy body dementia (LBD) and are predictive for neurodegeneration in Parkinson's disease. Obstructive sleep apnea (OSA) shares common risk factors with AD and may even be an integral part of the pathological process in AD. In MCI patients, the hypotheses in which (i) sleep disorders may represent early predictive factors for progression to dementia and (ii) MCI is symptomatic of a non-diagnosed sleep disorder remain to be elucidated. Guidelines for drug and non-drug treatments of sleep disorders in the elderly and in demented patients are also considered in this review. In healthy but frail elderly people and in early-stage AD patients, sleep should be more thoroughly characterized (notably by using standardized interviews and polysomnographic recording).

This study characterizes findings on sleep testing and Human Leukocyte Antigen (HLA) markers in a group of patients with fibromyalgia (FM) and chronic fatigue syndrome (CFS). One hundred eighteen patients seen in a general neurology practice over 5 years meeting standard clinical criteria for FM or CFS were analyzed retrospectively. Cases of untreated sleep apnea or restless legs syndrome were excluded prior to inclusion in this study. Ninety-two patients had multiple sleep latency testing (MSLT). Seventy-three (80%) were abnormal by standard criteria. Of 57 females having positive MSLTs, 22 (39%) had one or more periods of sleep onset rapid eye movement (SOREM), and 5 of 16 (31%) males with positive MSLTs had one or more SOREM. Highly fragmented sleep, as previously described in FM, was seen but not analyzed quantitatively. HLA DQB1*0602 was obtained in 74 patients, and positive in 32 (43%), P < 0.0001 compared with published values in 228 populations. In our patients, who presented with neuromuscular fatigue or generalized pain, we found a sleep disorder characterized by objective hypersomnia. Some patients had characteristics of narcolepsy. Objective assessment by sleep studies can assist the diagnostic process, aid future research, and provide rationale for treatment.

The field of sleep medicine has grown exponentially worldwide. Sleep apnea is linked to the obesity epidemic, which, in some regions of the United States, affects more than one-third of the population. Sleep alterations increase the risk of cardiovascular and cerebrovascular pathology through a diversity of direct and indirect mechanisms. Recent investigations have found a clinical correlation between sleep disorders and diabetes. Obese pregnant women are at high risk for development of sleep apnea and preeclampsia. New studies have uncovered that restless legs syndrome and periodic limb movements may increase the risk of hypertension and vascular disease. Sudden death in sleep may be preventable if conditions that lead to sudden death are investigated. New neuroimaging techniques during sleep in patients with insomnia have uncovered metabolic overactivity in areas of the brain related to maintenance of wakefulness. Sleep neuroimaging promises to have research and clinical diagnostic applications.

Sleep disorders are common in patients with end stage renal disease receiving hemodialysis or peritoneal dialysis. However also a well functioning renal graft does not cure the poor sleep pattern which now emerges as a problem even in early chronic kidney disease (CKD). When patients are made aware for the first time of a disease such as CKD, which may brink to dialysis or at the best to a renal transplant patients begin to experience a disordered sleep. Sleeping disorders include insomnia (I), sleep apnoea (SAS), restless legs syndrome (RLS), periodic limb movement disorder (PLMD), excessive daily sleeping (EDS), sleepwalking, nightmares, and narcolepsy. Disordered sleep did not meet the clinical and scientific interest it deserves, in addition and we do not have a well defined solution for sleeping complaints. However, awareness that a poor sleep is associated with poor quality of life and carries an increase in mortality risk has recently stimulated interest in the field. There are many putative causes for a disordered sleep in chronic kidney disease and in end-stage renal disease. For a unifying hypothesis demographic factors, lifestyles, disease related factors, psychological factors, treatment related factors, and social factor must be taken into consideration.

The importance of sleep on health has only been recently recognized, and the general public and the medical community are not yet fully knowledgeable about this issue. The great majority of sleep research has been performed in whites of European descent and to a lesser extent in African Americans, making generalization of the findings to other ethnic and racial groups difficult. Very little sleep research has been done in U.S. Hispanics. However, based on the available literature and the high prevalence of risk factors in Hispanics, such as obesity, diabetes, living in the inner city, and use of alcohol, the prevalence of such important sleep disorders such as obstructive sleep apnea and sleep habits such as poor sleep hygiene are suspected to be high. There is also some evidence that acculturation to the U.S. life style may lead to worse sleep habits in Hispanics, including fewer hours of sleep. Two current large NIH sponsored studies of sleep in U.S. Hispanics promise to significantly add to the literature on various sleep disorders such as sleep disordered breathing, insomnia, restless legs syndrome, periodic limb movement disorder, and sleep habits such as short sleep duration and sleep hygiene.

Sleep disorders such as insomnia, obstructive sleep apnoea (OSA), excessive daytime sleepiness (EDS) and fatigue, sleep deprivation and restless legs syndrome (RLS) are increasingly seen in clinical practice. Sleep is considered vital for preserving daytime cognitive function and physiological well-being. Sleep insufficiency may have deleterious effects on work-life balance, overall health and safety. The consequential economic burden at both the individual and societal levels is significant. Moreover, sleep disorders are commonly associated with other major medical problems such as chronic pain, cardiovascular disease, mental illness, dementias, gastrointestinal disorders and diabetes mellitus. Thus, in order to properly care for patients presenting with sleep-related morbidity, and to reduce the consequential economic burden, accurate screening efforts and efficacious/cost-effective treatments need to be developed and employed.

Sleep loss may result from total sleep deprivation (such as a shift worker might experience), chronic sleep restriction (due to work, medical conditions or lifestyle) or sleep disruption (which is common in sleep disorders such as sleep apnea or restless legs syndrome). Total sleep deprivation has been widely researched, and its effects have been well described. Chronic sleep restriction and sleep disruption (also known as sleep fragmentation) have received less experimental attention. Recently, there has been increasing interest in sleep restriction and disruption as it has been recognized that they have a similar impact on cognitive functioning as a period of total sleep deprivation. Sleep loss causes impairments in cognitive performance and simulated driving and induces sleepiness, fatigue and mood changes. This review examines recent research on the effects of sleep deprivation, restriction and disruption on cognition and neurophysiologic functioning in healthy adults, and contrasts the similarities and differences between these three modalities of sleep loss.

Sleep complaints and disorders are frequent in geriatric patients, with a prevalence of 57%. They result in increased morbidity and mortality. In this population, the primary goal is to search for a cause of secondary insomnia, such as organic or psychiatric diseases, or medications. In those cases, sleep will improve with the treatment of the cause. In the cases of primary insomnia, behavioral and sleep hygiene therapy are essential. Hypnotics have frequent side effects and should be avoided when possible. Prescription of small doses of benzodiazepines or related drugs should only be for a short period of time. Molecules with a short half life are to be preferred. Other sleep disorders include sleep apnea syndrome, restless legs syndrome and periodic limb movements, which are the most frequent diagnoses in an elderly population. In the restless legs syndrome, diagnostic workup must include the search for a cause and treatment should favor hygienic measures. The use of dopamine agonists must be cautious, as their tolerance is poor in the elderly. Periodic limb movements are also frequent but there is no particular therapeutic recommendation.

Sleep disorders are common and underrecognized in patients at all stages of chronic kidney disease. They include sleep apnea, insomnia, excessive sleepiness, restless legs syndrome and periodic limb movement disorder. They can be related to underlying uremia or comorbidities. Sleep disorders can affect the quality of life, and some are associated with increased morbidity and mortality. Clinical assessment, polysomnography and other standardized assessments are required for diagnosis. Therapeutic approaches include improvement in uremia management, treatment of comorbidities or specific interventions directed at individual sleep disorders. Diagnosis and treatment of sleep disorders in this population may improve quality of life and patient survival.
