Obstructive sleep apnea (OSA) remains under-recognized in women possibly due to differences in clinical presentation, difference in tolerance to symptoms, and rate of usage and referral to sleep services. No reports have addressed OSA in women in the Middle Eastern (Arab) population. Therefore, we conducted this study to assess the differences in demographics, clinical presentation, and polysomnographic (PSG) findings between Saudi women and men diagnosed to have (OSA). The study group comprised 191 consecutive Saudi women and 193 consecutive men who were referred to the Sleep Disorders Centre and were found by in-laboratory PSG to have OSA. Demographic and clinical data were obtained by personal interviews. Women were significantly older than men (53.9 and 43.0 years, respectively; p < 0.001). Similarly, their body mass index was significantly higher than men (p < 0.001). Insomnia was more common among women (39.8%) compared to men (25.9%; p = 0.005). Other sleep symptoms including witnessed apnea, and excessive daytime sleepiness did not show any statistical difference between the two groups. Women were more likely than men to be diagnosed with hypothyroidism, diabetes, hypertension, cardiac disease, and asthma. Apnea-hypopnea index (AHI) was statistically higher in men compared to women; however, most of apnea/hypopnea events in women occurred during rapid eye movement sleep, and the mean duration of hypopnea and apnea was significantly lower in women (p = 0.004). Sleep efficiency was lower in women (71.5% vs. 77.7%) in men (p < 0.001). The desaturation index was higher in men (p = 0.01), but no difference was found in lowest SaO2 or time with SaO2 less than 90%. The present study showed important clinical and PSG differences between Saudi women and men with OSA. Clinicians need to be aware of these differences when assessing women for the possibility of OSA as they may be symptomatic at a lower AHI and have significant comorbid conditions that can be adversely affected if their OSA was not timely managed.

The frequency of sleep disturbances in patients with epilepsy and their impact on quality of life (QoL) have been documented in a few reports, and the results are conflicting. We identified 124 consecutive epilepsy out-patients who visited the epilepsy out-patient clinics at the University Hospital of Alexandroupolis, the AHEPA Hospital in Thessaloniki and the Aeginitio Hospital in Athens. We measured excessive daytime sleepiness (EDS) with the Epworth Sleepiness Scale (ESS), obstructive sleep apnea (OSA) with the Sleep Apnea scale of the Sleep Disorders Questionnaire (SA-SDQ), and insomnia with the Athens Insomnia Scale (AIS). We evaluated quality of life by the Quality of Life in Epilepsy Inventory (QOLIE-31). EDS was found in 16.9% (21/124) of epileptic patients, OSA in 28.2% (35/124), and insomnia in 24.6% (30/122). In multivariate analysis, we found that insomnia was an independent negative factor for Total score (p<0.001), Overall QoL (p=0.002), Emotional well-being (p<0.001), Energy/fatigue (p<0.001), Cognitive functioning (p=0.04) and Social functioning (p=0.03), and OSA only for Cognitive functioning (p=0.01). According to our findings, EDS, OSA, and insomnia are frequent in epileptic patients. Epileptic patients with sleep disturbance, mainly insomnia, have significant QoL impairment.

Neuroimaging methods can be used to investigate whether sleep disorders are associated with specific changes in brain structure or regional activity. However, it is still unclear how these new data might improve our understanding of the pathophysiology underlying adult sleep disorders. Here we review functional brain imaging findings in major intrinsic sleep disorders (i.e., idiopathic insomnia, narcolepsy, and obstructive sleep apnea) and in abnormal motor behavior during sleep (i.e., periodic limb movement disorder and REM sleep behavior disorder). The studies reviewed include neuroanatomical assessments (voxel-based morphometry, magnetic resonance spectroscopy), metabolic/functional investigations (positron emission tomography, single photon emission computed tomography, functional magnetic resonance imaging), and ligand marker measurements. Based on the current state of the research, we suggest that brain imaging is a useful approach to assess the structural and functional correlates of sleep impairments as well as better understand the cerebral consequences of various therapeutic approaches. Modem neuroimaging techniques therefore provide a valuable tool to gain insight into possible pathophysiological mechanisms of sleep disorders in adult humans.

Sleep disorders affect women differently than they affect men and may have different manifestations and prevalences. With regard to obstructive sleep apnea (OSA), variations in symptoms may cause misdiagnoses and delay of appropriate treatment. The prevalence of OSA appears to increase markedly after the time of menopause. Although OSA as defined by the numbers of apneas/hypopneas may be less severe in women, its consequences are similar and perhaps worse. Therapeutic issues related to gender should be factored into the management of OSA. The prevalence of insomnia is significantly greater in women than in men throughout most of the life span. The ratio of insomnia in women to men is approximately 1.4:1.0, but the difference is minimal before puberty and increases steadily with age. Although much of the higher prevalence of insomnia in women may be attributable to the hormonal or psychological changes associated with major life transitions, some of the gender differences may result from the higher prevalence of depression and pain in women. Insomnia's negative impact on quality of life is important to address in women, given the high relative prevalence of insomnia as well as the comorbid disorders in this population. Gender differences in etiology and symptom manifestation in narcolepsy remain understudied in humans. There is little available scientific information to evaluate the clinical significance and specific consequences of the diagnosis of narcolepsy in women. Restless legs syndrome (RLS) is characterized by an urge to move the legs or other limbs during periods of rest or inactivity and may affect as much as 10% of the population. This condition is more likely to afflict women than men, and its risk is increased by pregnancy. Although RLS is associated with impaired quality of life, highly effective treatment is available.

During the past decade, the critical role of sleep in health and disease has been underscored by research that further defines the relationship between sleep and myriad physiologic and psychological functions as well as quality of life. For many years, there was little exploration of the significance of sleep and sleep disorders in cancer patients; however, the past decade has seen a steady growth of inquiry in this area. These investigations have demonstrated the high frequency and significance of sleep disturbance as a symptom in cancer patients. They have also explored the complex interaction between sleep and other common cancer symptoms, most notably fatigue, depression, and pain, and have identified risk factors associated with the development of sleep problems in this population. Although treatment studies lag behind, reports of effective psychological and behavioral interventions for insomnia in cancer patients are increasing. Several studies are addressing pharmacotherapeutic intervention for hot flashes as a potential source of sleep disturbance. Other sleep disorders, most notably obstructive sleep apnea, also occur with some regularity in cancer patients.

Chronic congestive heart failure is a highly prevalent and progressive disorder associated with excess morbidity and mortality; it has huge economic impact. Left heart failure may be systolic or may occur as isolated diastolic dysfunction. The diastolic form predominates in older people. Sleep disorders are frequent in both types. Most systematic studies have been performed in patients with systolic heart failure. Prospective studies show the presence of obstructive and central sleep apnea, periodic limb movements, and significant alterations in sleep architecture, characterized by poor efficiency, excess stage 1 and arousals, and lack of deep sleep. Both obstructive sleep apnea and central sleep apnea occur in patients with heart failure and have been shown to be associated with excess mortality. Obstructive sleep apnea is best treated with continuous positive airway pressure (CPAP) devices. Central sleep apnea is also best treated with CPAP, but only about 50% of the patients are considered responders. Survival improves when heart failure patients are effectively treated with CPAP for both central and obstructive sleep apnea. A new positive airway pressure device, a pressure support servo-ventilator, is the next best choice for heart failure patients whose central sleep apnea does not respond to CPAP. Nocturnal oxygen should be used for patients whose central sleep apnea does not respond to positive pressure devices. Both periodic limb movements and insomnia could have adverse hemodynamic consequences for the failing heart. There are no guidelines or long-term studies regarding treatment of these conditions in heart failure. For restless legs syndrome with or without periodic limb movements, pramipexole and ropinirole have been approved. Treatment of insomnia comorbid with heart failure depends on the cause. In the absence of any known cause, a trial of ramelteon is the first choice.

Children with autism spectrum disorders frequently have significant sleep problems, most commonly insomnia. Fortunately, a variety of treatments are available, including behavioral interventions and pharmacotherapy. When establishing a treatment plan, it is imperative to understand the underlying etiology of the sleep problem, which in many cases is multifactorial. Some sleep problems, such as suspected obstructive sleep apnea, should be referred to a sleep specialist. Identifying and treating sleep disorders may not only result in improved sleep but also may favorably affect daytime behavior and family functioning. In general, when treating insomnia, behavioral interventions should be instituted initially, followed by pharmacotherapy if needed.

The purpose of this study was to describe the function and structure of an interdisciplinary outpatient pediatric sleep clinic. In addition, the frequency of individual and comorbid sleep diagnoses, the prevalence of comorbid medical or psychiatric disorders, and the types of treatment recommendations and referrals provided to patients at the end of their clinic visits was examined. Over a 4-month period, 265 consecutive patients were evaluated in the sleep clinic by trainees, nurses, and attendings in pulmonary medicine, neurology, and psychology. Obstructive sleep apnea was the most common diagnosis, followed by behavioral insomnia of childhood. Over half of the patients had a comorbid medical diagnosis, and 31% had a comorbid psychiatric diagnosis. Polysomnography was the most common recommendation, with 38% of patients receiving at least one behavioral recommendation. The results of this descriptive study support the need for an interdisciplinary approach to pediatric sleep medicine, providing broad training to trainees of all disciplines while improving the clinical care for children with sleep problems.

The association between insomnia and sleep apnea has received little attention from health professionals in the past few decades. However, recent studies have shown a high prevalence of insomnia complaints in patients with objectively diagnosed obstructive sleep apnea (OSA) syndrome. In this paper we have reviewed data published on different aspects of this association: the clinical profile of sleep-disordered breathing (SDB)-plus, the nature of the association, the role in the onset of insomnia played by OSA itself and other comorbidity factors such as depression or the restless leg syndrome. Finally, we have reviewed data and hypotheses on the metabolic implications of OSA and insomnia, and we speculate on the role that hypothalamic-pituitary-adrenal axis hyperactivity may play in a hypothetical interrelation between OSA and insomnia. The apparent paradox implied by this clinical association reveals the need for interdisciplinary training for physicians who treat both types of disorders.

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.
