This cross-sectional, multivariate study investigated associations between sleep disordered breathing (SDB) and putative risk factors in a heterogeneous group of 720 individuals over the age of 50 years studied during all-night in-lab polysomnography. Results indicated that: aged men were more likely to show impaired respiration during sleep than aged women; excessive daytime somnolence and parasomniac symptoms (snoring, gasping during sleep) were associated with SDB but insomnia was not; obesity accounted for more variance in SDB than age per se, implying that the prevalence of SDB in some elderly persons could be related to the deposition of body fat seen as individuals grow older. All four risk factors (age, sex, obesity, and symptomatic status) were statistically significant and independent predictors of impaired respiration in sleep in the elderly.

Filling the pericardial sac with ice and saline during open heart surgery protects the myocardium during periods of ischemic arrest. Bilateral diaphragmatic paralysis complicated intense local hypothermia in five patients undergoing coronary artery bypass surgery. All complained of severe orthopnea, exertional dyspnea, insomnia, and excessive daytime somnolence. All exhibited paradoxic inward movement of the abdominal wall with inspiration. The diagnosis of bilateral diaphragmatic paralysis was confirmed with upright and supine spirometry and, in one patient, with transdiaphragmatic pressure measurements. Although paralysis has resolved in four patients, all experienced months of disabling impairment. One patient required four months of mechanical ventilatory support prior to her recovery. Alternative methods of intraoperative myocardial preservation that avoid this complication should be developed.

Excessive daytime sleepiness in the general community is a newly recognized problem about which there is little standardized information. Our aim was to measure the levels of daytime sleepiness and the prevalence of excessive daytime sleepiness in a sample of Australian workers and to relate that to their self-reported sleep habits at night and to their age, sex, and obesity. Sixty-five percent of all 507 employees working during the day for a branch of an Australian corporation answered a sleep questionnaire and the Epworth sleepiness scale (ESS) anonymously. Normal sleepers, without any evidence of a sleep disorder, had ESS scores between 0 and 10, with a mean of 4.6 +/- 2.8 (standard deviation). They were clearly separated from the "sleepy" patients suffering from narcolepsy or idiopathic hypersomnia whose ESS scores were in the range 12-24, as described previously. ESS scores > 10 were taken to represent excessive daytime sleepiness, the prevalence of which was 10.9%. This was not related significantly to age (22-59 years), sex, obesity, or the use of hypnotic drugs but was related significantly but weakly to sleep-disordered breathing (frequency of snoring and apneas), the presence of insomnia, and reduced time spent in bed (insufficient sleep).

Sleep-wake habits and control of postural muscle tone were investigated by self-report questionnaire in 183 subjects considered to have the narcoleptic syndrome, 62 subjects with hypersomnia and 10 with obstructive sleep apnoea. Results were compared with those in a group of 188 control subjects with normal sleep wake habits. Excessive daytime sleepiness, determined by the Epworth Sleepiness Scale (ESS), was five times greater in the narcoleptic syndrome than in control subjects (score range 0-24, mean scores +/-SD 19.6+/-3.0; and 4.5+/-3.3 respectively; P<0.001). The propensity to cataplexy, as determined by a rating scale developed to estimate the likelihood of loss of postural tone in response to sudden emotional stimuli, including laughter, was 10 times greater in narcoleptic syndrome than in control subjects (postural atonia total score range 0-600; mean + SD 334+/-122 and 28+/-45, respectively; P<0.001). Narcoleptics had more disturbances of night sleep than controls with episodes of muscle jerking, sleep walking, sleep talking and sleep terrors, as well as sleep paralysis, and higher insomnia self-rating scores. Sleep latency from bedtime to sleep-onset time was shorter in narcoleptics than controls. The hypersomniac group of 62 subjects was heterogeneous. Subsequent investigation showed that 18 subjects (29%) had idiopathic hypersomnia, four (6%) 'incomplete' narcolepsy without cataplexy and 10 (16%) hypersomnia accompanying a mood disorder. The mean ESS scores in this group and in subjects with obstructive sleep apnoea were comparable to those of the narcoleptic syndrome subject group. Mean postural atonia scores were similar to those of control subjects.

Sleep disorders are acknowledged to be common but remain underrecognized by the medical community, often attributed to the failure to question patients about their sleep quality. We examined the prevalence of sleep complaints (insomnia or excessive daytime sleepiness) in a group of general medical patients by administering a questionnaire to hospitalized patients in a Veterans Affairs tertiary care medical center. A total of 222 consecutive adults (215 men, 60 +/- 14 years; body mass index, 24.8 +/- 5.6) completed the questionnaire. Of these, 105 patients (47%) had either insomnia, excessive daytime somnolence, or both; 63 (28%) had excessive daytime somnolence, which was severe in 27 (12%). Of 75 patients (34%) who had insomnia, a third were taking hypnotic medication. Forty patients (18%) had snoring, which was associated with excessive daytime somnolence in 36, whereas 46 patients (21%) had either restless legs or a combination of leg jerks and leg kicking or twitching during sleep, associated with a sleep complaint (insomnia in 32). The medical records were subsequently reviewed to assess the admitting physicians' recognition of these symptoms. No record included mention of any patient symptom related to sleep. We conclude that symptoms related to sleep, some of which may be clinically important, are common, and that none of these complaints appear to be recognized by the physicians of record.

Sleep disorders are very prevalent in the general population and are associated with significant medical, psychological, and social disturbances. Insomnia is the most common. When chronic, it usually reflects psychological/behavioral disturbances. Most insomniacs can be evaluated in an office setting, and a multidimensional approach is recommended, including sleep hygiene measures, psychotherapy, and medication. The parasomnias, including sleepwalking, night terrors, and nightmares, have benign implications in childhood but often reflect psychopathology or significant stress in adolescents and adults and organicity in the elderly. Excessive daytime sleepiness is typically the most frequent complaint and often reflects organic dysfunction. Narcolepsy and idiopathic hypersomnia are chronic brain disorders with an onset at a young age, whereas sleep apnea is more common in middle age and is associated with obesity and cardiovascular problems. Therapeutic naps, medications, and supportive therapy are recommended for narcolepsy and hypersomnia; continuous positive airway pressure, weight loss, surgery, and oral devices are the common treatments for sleep apnea.

There are few epidemiological studies on sleep loss and daytime sleepiness in the general adult population of Japan. A total of 4000 adult people, aged 20 and over, were randomly drawn from five areas of Japan, and 3030 individuals were interviewed and completed a questionnaire including information about sleep duration and sleep problems. Overall, 29% slept less than 6 h at night, 23% reported having insufficient sleep, and 6% took sleep enhancing medications. The prevalence rates were 21% for symptoms of insomnia and 15% for excessive daytime sleepiness. Symptoms of insomnia were more prevalent in the elderly, whereas young people were more likely to report short sleep duration, subjective insufficient sleep and excessive daytime sleepiness. A multiple logistic regression model revealed that excessive daytime sleepiness had significant associations with young people, short sleep duration, insomnia symptoms, subjective insufficient sleep and sleep enhancing medication use. Short sleep duration was the strongest predictor of excessive daytime sleepiness. The findings indicate that sleep loss and excessive daytime sleepiness in the Japanese adult population are common, and comparable to those reported in Western countries. Excessive daytime sleepiness in the general adult population seems more likely to be attributed to short sleep duration.

Sleep disorders, both insomnia and hypersomnia, are commonly associated with various co-morbid conditions, including general medical and neurologic disorders, psychiatric illnesses, and secondary or symptomatic restless legs syndrome/periodic limb movements in sleep. Diagnosis of the co-morbidity is the first step in treatment, followed by an assessment of the sleep disturbance. This begins with a complete history and physical examination, followed by laboratory testing such as polysomnography, multiple sleep latency testing, and actigraphy. The treatment of sleep disorders caused by co-morbid conditions is discussed under seven categories, including the use of general measures (e.g., sleep hygiene, encouraging patients to develop good sleep habits, medication), treatment of the co-morbid condition, treatment of insomnia, treatment of excessive daytime somnolence, treatment of parasomnias, treatment of sleep-wake schedule disorders, and treatment of secondary or symptomatic restless legs syndrome.

Sleep disorders commonly complicate the course following traumatic brain injury (TBI). Insomnia, excessive daytime somnolence and alteration of the sleep-wake schedule are common disturbances that affect the course of recovery and prognosis in TBI survivors. Few studies, however, have looked at the diagnosis and management of these disturbances in TBI. Early treatment of sleep disorders must be considered an integral part of the rehabilitation process. Recognition and management of comorbid medical or surgical diseases, assessment and treatment of associated psychiatric disorders, and awareness of other psychosocial stressors are mandatory steps in the management of sleep disturbances following TBI. In addition to pharmacologic therapy, nonpharmacologic approaches such as diet, environmental modification, and behavioral interventions are essential components in the management of sleep disturbances in TBI. Based on the evidence that sleep disturbances impact rehabilitation in TBI patients we support the need for ongoing studies in this area.

Excessive daytime sleepiness is a serious medical problem. It appears against patient will, when he performs normal day activities. It significantly disturbes daily functioning and may be a cause of a serious accidents. Approximately 5% of the general population suffers from excessive daytime sleepiness. The most common cause of daytime sleepiness is sleep deprivation. It is also a symptom of many disorders and may be an effect of taking many drugs, especially sedative ones. Investigation continued in the seventies by W. Dement and M. Carscadon resulted in preparation of MSLT which became the most widely used, objective method of the assessment of excessive sleepiness. It has been quickly used in diagnosis of narcolepsy, obstructive sleep apnea, idiopathic hypersomnia, periodic limb movements, circadian rhythms disorders, insomnia investigations, clinical assessment of many drugs. However equipment requirements are not that complicated, but investigator knowledge and experience are the limitations of the method. We described the protocol of the test including EEG procedures, patient preparation, interpretation of the results and normal values. Indications for MSLT in the diagnosis of sleep disorders were outlined with the special emphasis on narcolepsy.
