To enhance physicians' knowledge of the prevalent problem of sleep disorders, a 50-minute videotape program designed as a learning and self-assessment experience in evaluating and treating these disorders was coproduced with the Network for Continuing Medical Education. The program has been presented nationally to about 25,000 medical professionals. The mean correct score was 50% for the pretest, 69% for the instructional section, and 79% for the posttest; the composite score on the posttest was 59% higher than that on the pretest. Physicians' responses indicated strengths and weaknesses in their knowledge of sleep disorders, thus delineating future directions for medical education in insomnia, narcolepsy/cataplexy, nightmares, night terrors, sleepwalking, and enuresis. All of these sleep disorders can be best evaluated and treated by the general physician.

Sleep is a vital human physiologic process. Insomnia can be caused by obsession and depression states, pain, or worry over everyday problems. Because of their pharmacologic action, alcohol and high doses of soporifics used as remedies may produce REM-deficit sleep and actually prolong insomnia. If the true cause of sleeplessness is not recognized and properly treated, insomnia may develop into a severe sleep problem. Since benzodiazepines and chloral hydrate do not suppress REM sleep, they are the medications of choice in the therapy for insomnia.

The authors determined the prevalence of sleep disorders in a general population through a survey of 1,006 representative households in the Los Angeles metropolitan area. They found an overall prevalence of current or previous sleep disorders in adults of 52.1%. Specifically, they found a 42.5% prevalence of insomnia, 11.2% of nightmares, 7.1% of excessive sleep, 5.3% of sleeptalking, and 2.5% of sleepwalking. These conditions were often chronic and usually started early in life. Insomnia was more frequent in older people, particularly older women, and in people of lower educational socioeconomic status. Insomnia, nightmares, and hypersomnia were correlated with more frequent general physical and mental health problems.

"When a patient comes to us with the complaint of insomnia, we have to consider 5 items: 1) the psychological structure; 2) the existence of sleep disorders in the family; 3) the antecendents of sleep disorders in the childhood; 4) the appearance (or reappearance several years later) of the insomnia; 5) the present situation. In our research, we have studied the evolution of a group of insomniacs, since the appearance of the symptom until the time when they came to our department. In order to define this evolution, we have compared these two successive situations, having choosen as criteria, the opposition existing between the motivation and problematic on the one hand, and the exterior constraints on the other hand."

Primary sleep disorders include narcolepsy, the Pickwickian syndrome, sleep apnea in infants and other rare conditions. Secondary sleep disorders occur in depression, alcoholism, endocrinopathies, heart failure and pregnancy. Medical symptomatology often increases during rapid-eye-movement (REM) sleep, when physiologic activity is high. Insomnia, the most common sleep disorder, requires careful work-up, attempts at environmental manipulation and judicious short-term pharmacotherapy. Pharmacologic manipulation of sleep is beset with complications. A basic understanding of properties and side effects of the sleep-inducing drugs is needed in order to select the optimal agent.

Modern sleep research studies have provided the practicing physician with considerable new information concerning the basic psychophysiology of sleep, the effects of medical conditions on sleep and the role of maturational and emotional factors in producing certain sleep disorders. Medical and psychiatric disorders, sleep disorders and drug-induced sleep stage alterations are studied in the sleep laboratory using the same techniques developed to analyze sleep patterns in normal subjects. After initial sleep laboratory adaptation, a profile of the sleep characteristics of various clinical conditions is obtained. This profile can be compared to sleep profiles of normal subjects as well as to the effects on sleep of subsequent experimental or therapeutic procedures. Various studies have shown that coronary artery, duodenal ulcer and nocturnal headache patients experience angina, increased gastric acid secretion and migraine or cluster headaches, respectively during REM sleep. Adult nocturnal asthamtic episodes occur out of all sleep stages while attacks of dyspnea in asthmatic children occur in all stages except stage 4 sleep. Hypothyroid patients show decreases in stages 3 and 4 sleep, while in hyperthyroid patients the percentage of time spent in stages 3 and 4 sleep is markedly increased. Enuretic episodes occur predominantly in non-rapid eye movement (NREM) sleep. Sleepwalking and night terror episodes occur exclusively out of NREM sleep, particularly from stages 3 and 4 sleep. Most child somnambulists and children with night terrors "outgrow" this disorder, suggesting a delayed maturation of the central nervous system. Stimulant drugs are effective in the treatment of the sleep attacks of narcolepsy and in treating certain cases of hypersomnia, while imipramine is an effective treatment for the auxillary symptoms of narcolepsy. Psychological disturbances are frequent in adult somnambulism and night terrors as well as in hypersomnia and insomnia. Proper pharmacologic treatment to provide symptomatic relief for insomnia is recommended to enhance the psychotherapeutic process.

Of 250 patients referred to the Stanford Sleep Disorders Clinic, 35 were diagnosed for a sleep induced apnea syndrome. Thirty of them (27 adults and 3 children) were nonobese and complained of a sleep disorder. In 12 patients (9 adults and 3 children) extensive cardiorespiratory workups were done during sleep and wakefulness. Three types of sleep induced apnea syndrome were identified: diaphragmatic (or central), obstructive and mixed. The diaphragmatic type was predominant in sleep apnea insomnia; obstructive was predominant in sleep apnea hypersomnia. Hemodynamic changes were documented during sleep. Tracheostomy, done in two cases, improved the sleep induced symptomatology.

Very few epidemiological surveys have specifically studied relationships between sleep disturbances and psychiatric diseases. In this review, we preferred to use the classification proposed in 1979 by the Association of Sleep Disorders Centers. It includes four main categories: insomnias, excessive sleepiness, troubles of the wake/sleep schedule and parasomnias. Evaluating psychiatric disorders among general populations is easier owing to DSM III and DSM III-R criteria, but there are not equivalent criteria in evaluating sleep disorders. It is almost impossible to realize polysomnographic recordings in large samples, therefore sleep disorders are to be detected by questionnaires. It has been shown that there is a good correlation between self-reports and polysomnographic recordings among clinical and general samples. The prevalence of insomnia, defined as difficulties of initiating and maintaining sleep, is estimated between 9 and 31%. It is higher among women, elderly people, separated and divorced subjects, and low educational levels' groups. It has to be noticed that polysomnographic records of some subjective insomniacs are not different from those of good sleepers, sleep latency excepted. These subjective (and not objective) insomniacs have high scores in anxiety scale, depression scale, or psychologic distress. Insomnia is more frequently noted amongst subjects with psychiatric diagnoses, especially major depressive disorders and anxiety disorders. Depressive disorders are present in 21-40% of insomniacs versus 0-1% of non-insomniacs, and anxiety disorders in 13-24% of insomniacs versus 3-10% of non-insomniacs. In depressive disorders, sleep alterations are frequently noted: they are difficulties of initiating and maintaining sleep, decreasing proportion of slow-wave sleep, decreasing time of REM (rapid eye movement) sleep and REM sleep latency, and increasing density of REM sleep. Of these modifications, the last two ones seem to be specific for depression. The relationships between sleep, aging and depression are more complex than previously noted. For example, differences between depressed and non-depressed subjects depend on the age of the population. The prevalence of hypersomnia is lower than the insomnia's. It varies between 2 and 4%. It is more frequently noted among young people, and never married subjects. Two specific aetiologies must be looked for: sleep apnea syndrome and narcolepsy. These diagnoses are respectively found in 45% and 24% of hypersomniacs examined in American Sleep Centers. Hypersomnias are objectived by the Multiple Sleep Latency Test, which measures the physiologic sleep tendency.(ABSTRACT TRUNCATED AT 400 WORDS)

Sleep disorders are especially common among elderly patients and may be the result of psychiatric illness, a medical problem, poor sleep habits, or a primary sleep disorder. Because a sleep complaint (especially insomnia) is only a symptom, the physician must undertake a careful evaluation in an attempt to identify a specific treatable cause. Although some patients may require referral to a psychiatrist or sleep disorders clinic, many patients may benefit from behavioral strategies, such as improved sleep hygiene. In general, hypnotics should be prescribed for only a limited period of time and should be combined with other therapeutic approaches in patients with chronic insomnia.

Physiological sleep induction is a fragile phenomenon which may be altered by environmental factors and various somatic and psychiatric disorders. Therefore sleep induction disorder is a common component of different types of insomnia, including sleep-onset insomnia and to a lesser degree multiple awakenings insomnia and early morning awakening insomnia. The treatment of sleep induction disorders is difficult and requires a precise analysis of the disorder and its aetiological factors. Specific treatment of aetiological factors is more likely to be efficacious in the long term than pharmacological sleep induction (eg: psychiatric disorders, sleep apnea syndrome, restless leg syndrome, periodic movements in sleep, disorders of the sleep-wake schedule...) when the use of hypnotic drugs is necessary agents not altering sleep architecture are preferred. Non-pharmacological methods could be used to induce sleep because they provide a better long term efficacy: sleep hygiene, relaxation techniques, biofeedback technique, psychotherapeutic techniques. Recently, some authors stress the use of treatment by restriction of time in bed and stimulus control treatment.
