These clinical guidelines, which have been reviewed and approved by the Board of Directors of the American Sleep Disorders Association, provide recommendations for the practice of sleep medicine in North America regarding the indications for polysomnography in the diagnosis of sleep disorders. Diagnostic categories that are considered include the following: sleep-related breathing disorders; neuromuscular disorders and sleep-related symptoms; chronic lung disease; narcolepsy; parasomnias; sleep-related epilepsy; restless legs syndrome; periodic limb movement disorder; depression with insomnia; and circadian rhythm sleep disorders. Whenever possible, conclusions are based on evidence from review of the literature. Where scientific data are absent, insufficient, or inconclusive, recommendations are based on consensus of opinion. The Standards of Practice Committee of the American Sleep Disorders Association appointed a task force to review the topic, the indications for polysomnography and related procedures. Based on the review and on consultation with specialists, the subsequent recommendations were developed by the Standards of Practice Committee and approved by the Board of Directors of the American Sleep Disorders Association. Polysomnography is routinely indicated for the diagnosis of sleep-related breathing disorders; for continuous positive airway pressure (CPAP) titration in patients with sleep-related breathing disorders; for documenting the presence of obstructive sleep apnea in patients prior to laser-assisted uvulopalatopharyngoplasty; for the assessment of treatment results in some cases; with a multiple sleep latency test in the evaluation of suspected narcolepsy; in evaluating sleep-related behaviors that are violent or otherwise potentially injurious to the patient or others; and in certain atypical or unusual parasomnias. Polysomnography may be indicated in patients with neuromuscular disorders and sleep-related symptoms; to assist in with the diagnosis of paroxysmal arousals or other sleep disruptions thought to be seizure-related; in a presumed parasomnia or sleep-related epilepsy that does not respond to conventional therapy; or when there is a strong clinical suspicion of periodic limb movement disorder. Polysomnography is not routinely indicated to diagnose chronic lung disease; in cases of typical, uncomplicated, and noninjurious parasomnias when the diagnosis is clearly delineated; for patients with epilepsy who have no specific complaints consistent with a sleep disorder; to diagnose or treat restless legs syndrome; for the diagnosis of circadian rhythm sleep disorders; or to establish a diagnosis of depression.

Pathologic nocturnal eating can be associated with a heterogeneous group of medical and psychiatric disorders. The current study was designed to evaluate the prevalence and clinical features of nocturnal eating syndrome (NES), a major subtype of pathological nocturnal eating. Conducted prospectively over an 18-month period (January 1994-June 1995), the study consisted of clinical, psychological, and polysomnographic assessments of 120 adult subjects (51 males, 69 females; mean age 42.6 years, range 18-86 years) who were either self-referrals (58%) or physician referrals (42%) to our Sleep Disorders Center for insomnia complaints. Nocturnal eating with features that are typical of NES, namely compulsive feeding shortly after a mid-non-rapid eye movement (NREM) sleep awakening, in the absence of daytime eating disorders, occurred in seven subjects (five females, two males; mean age 50.8 +/- 9.5 years; mean age at onset of NES 42 years, range 18-61 years), or 5.8% of the sample. NES accounted for 44.4% of all the nocturnal eating cases observed. The data suggest that an adult, late-onset variety of NES is not infrequent. Several of the clinical features of our NES patient series correspond closely to most of those observed in other descriptions of NES in the literature. Overall, the data reinforce the idea that NES is a distinct syndrome, even though some of its features overlap with sleep-related eating disorders (e.g. associated with sleepwalking, restless legs syndrome, obstructive sleep apnea, etc.) and with eating disorders such as daytime binge eating.

The survey of insomnia, sleep breathing disorders and circadian rhythm sleep disorders in the world included Japan were reviewed in this article. We introduced the 1995 annual report of the national research project team supported by the grant of the Ministry of Health and Welfare that 18.7% of men and 20.3% of women in the outpatients of 11 general hospitals of Japan had severe sleep problems, and 11.7% of the patients had the persistent insomnia. Okada et al. estimated a prevalence of 3.28% of men for the obstructive sleep apnea syndrome in Japan. The survey by the telephone and self-reported questionnaire in the general population was reported that the prevalence of possible patients of circadian rhythm sleep disorders was estimated at 0.44% of Japanese.

We report a case of Creutzfeldt-Jakob disease (CJD) which at the beginning of the disease presented clinical syndrome of progressive supranuclear palsy. Rapid intellectual deterioration, supranuclear palsy, postural instability and myoclonic jerks suggested clinical diagnosis of CJD. After five months suffering from the disease patient developed obstructive sleep apnea syndrome (OSAS) confirmed by serial polysomnograms. OSAS is discussed in the context of the localization of histopathological findings and possible involvement of central autonomic structures. The main structures affected by spongiosis and astrogliosis were cortex, thalamus, basal ganglia and midbrain. OSAS was found as another sleep disturbance in CJD apart from insomnia and sleep-wake cycle abnormalities.

Chronic insomnia is the most common sleep complaint which health care practitioners must confront. Most insomnia patients are not, however, seen by sleep physicians but rather by a variety of primary care physicians. There is little agreement concerning methods for effective assessment and subsequent differential diagnosis of this pervasive problem. The most common basis for diagnosis and subsequent treatment has been the practitioner's clinical impression from an unstructured interview. No systematic, evidence-based guidelines for diagnosis exist for chronic insomnia. This practice parameter paper presents recommendations for the evaluation of chronic insomnia based on the evidence in the accompanying review paper. We recommend use of these parameters by the sleep community, but even more importantly, hope the large number of primary care physicians providing this care can benefit from their use. Conclusions reached in these practice parameters include the following recommendations for the evaluation of chronic insomnia. Since the complaint of insomnia is so widespread and since patients may overlook the impact of poor sleep quality on daily functioning, the health care practitioner should screen for a history of sleep difficulty. This evaluation should include a sleep history focused on common sleep disorders to identify primary and secondary insomnias. Polysomnography, and the Multiple Sleep Latency Test (MSLT) should not be routinely used to screen or diagnose patients with insomnia complaints. However, the complaint of insomnia does not preclude the appropriate use of these tests for diagnosis of specific sleep disorders such as obstructive sleep apnea, periodic limb movement disorder, and narcolepsy that may be present in patients with insomnia. There is insufficient evidence to suggest whether portable sleep studies, actigraphy, or other alternative assessment measures including static charge beds are effective in the evaluation of insomnia complaints. Instruments such as sleep logs, self-administered questionnaires, symptom checklist, or psychological screening tests may be of benefit to discriminate insomnia patients from normals, but these instruments have not been shown to differentiate subtypes of insomnia complaints.

Complaints of poor sleep are very common in people with chronic respiratory disorders. In patients with chronic obstructive pulmonary disease (COPD), poor sleep may be due to many causes, including cough, excess mucous production, and frequent arousals from sleep caused by hypercapnia, as well as secondary to medications used to manage the lung disease. Patients with obstructive sleep apnea (OSA) also complain of excessive daytime sleepiness and fatigue due to poor-quality sleep, although the mechanism of sleep disruption is somewhat different from that in patients with COPD. Although benzodiazepines are often the drugs of choice for the management of insomnia, caution is suggested with the use of these agents in patients with chronic obstructive respiratory disease due to the reduction in upper airway muscle tone and blunting of the arousal response to hypercapnia. However, controlled trials with short-acting benzodiazepine receptor antagonists, including triazolam, zolpidem, and zaleplon, suggest that these agents may be safely used in selected patients who have mild to moderate COPD without daytime hypercapnia. Less data are available on the use of these agents for patients with OSA, but a preliminary trial using zaleplon suggests that respiratory function is not adversely affected in patients with mild to moderate OSA. Studies are needed to further define the benefit-risk ratio of the use of benzodiazepine receptor agonists for the management of insomnia in patients with chronic obstructive lung disease.

Since it was shown that numerous neurological, psychiatric and internal illnesses have characteristics manifested during, or influenced by sleep, somnology has been playing a clinically more and more important role. Among the 88 diagnoses listed by ICD, not only insomnia, but also sleep-related respiratory disorders, in particular the obstructive sleep apnea syndrome, are of special importance. Sleep apnea is associated with coronary heart disease, myocardial insufficiency and other pathological conditions. Already in the doctor's office, a carefully taken history (nocturnal apnea alternating with irregular snoring, and diurnal sleepiness) can arouse an appropriate suspicion. This can be confirmed by an ambulatory polygraphic exploration. The definitive diagnosis is then established with the aid of polysomnography in the sleep lab where specific treatment is also initiated.

Confusional arousals, or sleep drunkenness, occur upon awakening and remain unstudied in the general population. We selected a representative sample from the United Kingdom, Germany, and Italy (N = 13,057) and conducted telephone interviews. Confusional arousals were reported by 2.9% of the sample: 1% (95% confidence interval: .8 to 1.2%) of the sample also presented with memory deficits (53.9%), disorientation in time and/or space (71%), or slow mentation and speech (54.4%), and 1.9% (1.7% to 2.1%) reported confusional arousals without associated features. Younger subjects (< 35 years) and shift or night workers were at higher risk of reporting confusional arousals. These arousals were strongly associated with the presence of a mental disorder with odds ratios ranging from 2.4 to 13.5. Bipolar and anxiety disorders were the most frequently associated mental disorders. Furthermore, subjects with Obstructive Sleep Apnea Syndrome (OSAS), hypnagogic or hypnopompic hallucinations, violent or injurious behaviors, insomnia, and hypersomnia are more likely to suffer from confusional arousals. Confusional arousals appears to occur quite frequently in the general population, affecting mostly younger subjects regardless of their gender. Physicians should be aware of the frequent associations between confusional arousals, mental disorders, and OSAS. Furthermore, the high occurrence of confusional arousals in shift or night workers may increase the likelihood of inappropriate response by employees sleeping at work.

This overview discusses pathogenesis, clinical presentation, prognostic implications and therapy of central sleep apnea with special reference to Cheyne-Stokes-Respiration or periodic breathing. In contrast to obstructive sleep apnea due to upper airway collapse during sleep, central sleep apnea (CSA) is mainly due to an instability of the breathing control system. Causes of central sleep apnea include alveolar hypoventilation disorders, heart failure, neurologic and autonomic disorders and idiopathic forms of CSA. Patients with idiopathic CSA often complain of insomnia and awakening during sleep but may also suffer from daytime sleepiness. Cheyne-Stokes-Respiration or peridic breathing is often associated with heart failure and neurological disorders especially those involving the brainstem. In heart failure periodic breathing has enormous prognostic implications. Treatment options for central sleep apnea are oxygen supplementation, medical therapy (i.e. acetazolamide) and CPAP. For patients with central sleep apnoea associated with alveolar hypoventilation nasal ventilation is treatment of choice. Newer nasal ventilation techniques (BiPAP, AutoSetCS) are under investigation for heart failure patients with Cheyne-Stokes-Respiration.

A significant proportion of the population has chronic sleep problems necessitating an increasing involvement by the primary care physician. Also, the general patient population is becoming more familiar with these disorders and is seeking assistance. Because sleep studies are expensive and time consuming, adhering to the recognized indications for testing reduces the number of inappropriate studies. Under most circumstances, individuals with excessive daytime sleepiness and symptoms suggestive of obstructive sleep apnea are candidates for polysomnography. Other individuals with parasomnias or difficult-to-treat insomnia are also candidates for testing. In some circumstances, procedures designed to assess sleepiness may also need to be used to ascertain the impact of the disorder on daytime functioning and may be part of evaluations involving the transportation industry. Only after taking a thorough history and doing a physical examination can the physician make an accurate determination of the appropriate study type.
