Cognitive behavioural therapy for primary insomnia: a systematic review.

AIM: This paper reports a systematic review of seven studies evaluating the efficacy of cognitive behavioural therapy (CBT) for persistent primary insomnia. BACKGROUND: Insomnia is one of the most common health complaints reported in the primary care setting. Although non-pharmacological treatments such as the CBT have been suggested to be useful in combating the persistent insomnia, the efficacy and clinical utility of CBT for primary insomnia have yet to be determined. METHOD: A systematic search of Ovid, MEDLINE, psychINFO, PsycARTICLES, CINAHL, and EMBASE databases of papers published between 1993 and 2004 was conducted, using the following medical subject headings or key words: insomnia, primary insomnia, psychophysiological insomnia, sleep maintenance disorders, sleep initiation disorders, non-pharmacological treatment, and cognitive behavioural therapy. A total of seven papers was included in the review. FINDINGS: Stimulus control, sleep restriction, sleep hygiene education and cognitive restructuring were the main treatment components. Interventions were provided by psychiatrists except for one study, in which the CBT was delivered by nurses. Among beneficial outcomes, improvement of sleep efficacy, sleep onset latency and wake after sleep onset were the most frequently reported. In addition, participants significantly reduced sleep medication use. Some studies gave follow-up data which indicated that the CBT produced durable clinical changes in total sleep time and night-time wakefulness. CONCLUSIONS: These randomized controlled trial studies demonstrated that CBT was superior to any single-component treatment such as stimulus control, relaxation training, educational programmes, or other control conditions. However, heterogeneity in patient assessment, CBT protocols, and outcome indicators made determination of the relative efficacy and clinical utility of the therapy difficult. Therefore, the standard components of CBT need to be clearly defined. In addition, a comprehensive assessment of patients is essential for future studies.

Disturbed sleep and its relationship to alcohol use.

STUDY OBJECTIVES: To review evidence of an association between disturbed sleep and alcohol use. DESIGN: We searched MEDLINE, PSYCHINFO, ETOH, BIBLIOSLEEP and the Rutgers Alcohol Studies databases between January 1966 and August 2002. Search terms included alcohol-related disorders or alcoholism in combination with sleep, sleep initiation and maintenance disorders, or sleep apnea syndromes. The search produced over 440 citations. We reviewed 107 relevant articles, of which 60 included quantitative measures of both alcohol use and sleep. MEASUREMENTS AND RESULTS: Behavioral studies suggest that up to 2 to 3 standard drinks before bedtime initially promotes sleep, but these effects diminish in as few as 3 days of continued use. Clinical investigations support a relationship between sleep disturbance and alcohol use, but variability in the definition and measurement of these domains and a preponderance of cross-sectional studies make uncertain the strength and direction of the association. CONCLUSIONS: The association of insomnia with alcohol use disorders suggests that the clinical evaluation of patients with sleep problems should include a careful assessment of alcohol use. Future studies of this relationship should employ prospective designs with standardized, validated measures of both sleep and alcohol use. Rigorous treatment studies for chronic insomnia in alcohol dependent patients are also needed.

A systematic review of patient-reported outcome instruments measuring sleep dysfunction in adults.

Sleep dysfunction can manifest in several ways, ranging from insomnia to somnolence, and from disrupted sleep to lack of restful sleep. Measuring sleep dysfunction is an area of active research and there exist a number of patient-reported outcome instruments that measure various aspects of sleep dysfunction. However, these instruments have not been evaluated systematically. We used a conceptual model of sleep that included four physical domains of general interest to patients and investigators, and cover the breadth of this disorder: sleep initiation; sleep maintenance; sleep adequacy; and somnolence. We next considered the additional health-related quality-of-life (HR-QOL) domains of psychological and social functioning, progressing along the continuum to include health perceptions and opportunity. We then conducted a literature review to identify instruments and, using criteria developed by the Medical Outcomes Trust Scientific Advisory Committee, evaluated these instruments for their potential use in measuring sleep dysfunction. Twenty-two instruments were identified. Six instruments were found to include the four physical domains defined a priori (Basic Nordic Sleep Questionnaire, Leeds Sleep Evaluation Questionnaire, Medical Outcomes Study - Sleep Problems Measures, Pittsburgh Sleep Diary, Pittsburgh Sleep Quality Index, Self-Rated Sleep Questionnaire and the Sleep Dissatisfaction Questionnaire). Several additional instruments addressed at least some of the domains and thus may be useful for specific purposes. A few instruments addressed overall HR-QOL, but did not include all four domains of interest (Functional Outcomes of Sleep Questionnaire, Quality of Life in Insomniacs and the Sleep-Wake Activity Inventory). Two instruments had undergone extensive psychometric evaluation (Medical Outcomes Study - Sleep Problems Measures and Pittsburgh Sleep Quality Index), with only the latter reporting information about interpretability. Our review indicates that measuring sleep dysfunction in adults is an area of active research and that much work still needs to be completed, specifically the study of interpretability and the application of patient preferences or item response theory. The specific research focus should dictate instrument selection.

Sleep and wakefulness disturbances in Parkinson's disease.

Patients with Parkinson's disease experience prominent difficulties in maintaining sleep, painful night-time abnormal movements, and daytime sleepiness, sometimes culminating in sleep attacks. Recent insights into the pathophysiology of sleep disorders in PD points to a complex interaction between movement disorders, side-effects of dopamine agents and lesions in sleep-wake regulating systems. Treatment with dopamine agonists provides a twice higher risk of daytime sudden sleep episodes than levodopa, with no difference between ergotic and non ergotic compounds. Insomnia can be improved by a better control of night-time disability, restless legs syndrome and dystonia using subthalamic nucleus stimulation or night-time levodopa. A specific REM sleep disorder contributes to REM sleep behavior disorder and also to hallucinations (suggesting they could be awake dreams) and excessive daytime sleepiness. The management of sleep and alertness problems requires to analyze their potential causes, to monitor night-time and daytime sleep, and to subtly adjust psychotropic and dopaminergic treatment.

Sleep in panic disorders.

Panic disorder is a common anxiety disorder, which has relatively often its onset during adolescence. Besides panic attacks and avoidance behavior the patients often have sleep disturbances. They suffer from insomnia, nocturnal panic attacks, fear of going to bed or falling asleep and drug- or alcohol-related symptoms such as withdrawal phenomena.

Sleep impairment in patients with social phobia.

Patient reports of sleep difficulty and sleep quality were systematically assessed in 30 nondepressed, untreated patients with the generalized subtype of social phobia and 30 sex-matched and age-comparable healthy control subjects. Sleep characteristics of the preceding month were assessed using a standardized, validated instrument: the Pittsburgh Sleep Quality Index (PSQI). Patients with generalized social phobia reported significantly poorer sleep quality, longer sleep latency, more frequent sleep disturbance, and more severe daytime dysfunction. Global PSQI scores did not differ significantly among social phobia with or without a lifetime history of major depression (48%), comorbid dysthymia (15%), or comorbid avoidant personality disorder (64%). These findings, which are reminiscent of those in other anxiety syndromes such as panic disorder, suggest that disturbed sleep may be a feature of the generalized subtype of social phobia that deserves further clinical and research attention.

Reports of smoking withdrawal symptoms over a 21 day period of abstinence.

This paper presents results from a study which examined the occurrence and time course of smoking withdrawal symptoms in a group of 33 smokers followed over a 21 day period of abstinence. Smoking withdrawal symptoms examined included: irritability, feeling sleepy, sleeplessness, dizziness, coughing, tightness in the chest, constipation, mouth sores, and cravings for a cigarette. Findings showed a fairly consistent pattern of reduction across days of abstinence for six of the nine symptoms examined--irritability, feeling sleepy, dizziness, coughing, tightness in the chest, and cravings. Most symptoms decreased sharply during the first few days of cessation followed by a continued, but slower rate of decline in the second and third week of abstinence. Heavy smokers tended to report more withdrawal symptoms than light smokers, although the difference between heavy and light smokers was statistically significant only with respect to irritability. The implications of these findings for relapse prevention are discussed.

Insomnia among addicts during supervised withdrawal from opiates: a comparison of oral methadone and electrostimulation.

Measures of sleep disturbance were taken among drug-dependent inpatients being withdrawn from opiates using either a conventional oral methadone regime or electrostimulation (ES). Sleep was found to be disturbed in both groups. Subjects receiving ES showed the more marked sleep reduction and higher levels of night time waking during withdrawal: insomnia was most evident during the first 14 days of withdrawal. The degree of sleep disturbance among the methadone subjects was less severe but there were also sleep difficulties in this group. As late as 1 month after admission there was considerable night-to-night variability in sleep times with mean values between 4 h and 6 h in both groups. The ES procedure was unsatisfactory for managing insomnia during opiate withdrawal, but neither can methadone be regarded as fully satisfactory in this respect. An incidental finding to emerge from this study is that those subjects in the ES group who remained in treatment experienced more sleep disturbance than those who dropped out prematurely.

Sleep loss and postpartum psychosis.

Postpartum psychosis is a rare but severe psychiatric disorder. Its diagnostic status remains controversial, but several studies have shown that the majority of patients who develop psychosis immediately following childbirth suffer from bipolar disorder. The pathophysiology of postpartum psychosis is poorly understood, but factors such as primiparity, difficult labor, genetic predisposition, and hormonal changes have been suggested as etiological factors. This paper reviews the literature on the relationship of sleep disruption and postpartum psychosis. It is argued that sleep loss resulting from the interaction of various putative causal factors may be the final common pathway in the development of psychosis in susceptible women. Clinical significance of these findings, including strategies to prevent postpartum psychosis, are discussed and suggestions are made for future research directions.

Practice parameters for the indications for polysomnography and related procedures: an update for 2005.

These practice parameters are an update of the previously-published recommendations regarding the indications for polysomnography and related procedures in the diagnosis of sleep disorders. Diagnostic categories include the following: sleep related breathing disorders, other respiratory disorders, narcolepsy, parasomnias, sleep related seizure disorders, restless legs syndrome, periodic limb movement sleep disorder, depression with insomnia, and circadian rhythm sleep disorders. 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 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 the diagnosis of paroxysmal arousals or other sleep disruptions thought to be seizure related; in a presumed parasomnia or sleep related seizure disorder that does not respond to conventional therapy; or when there is a strong clinical suspicion of periodic limb movement sleep 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 seizures 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.

Physiological activation in patients with Sleep State Misperception.

OBJECTIVE: Sleep State Misperception insomnia has been commonly viewed as a perceptual or psychological problem. It was hypothesized that Sleep State Misperception insomnia, like psychophysiological insomnia, could be associated with increased physiological activation, here indexed by whole body metabolic rate. METHOD: Groups of nine patients with Sleep State Misperception insomnia and age-, sex-, and weight-matched normal sleepers were evaluated on sleep, performance, mood, personality, and metabolic measures over a 36-hour sleep laboratory stay. RESULTS: Sleep State Misperception insomniacs had a subjective history of poor sleep and perceived their laboratory sleep as poor but had electroencephalogram (EEG) parameters that did not differ statistically from matched normal controls. Sleep State Misperception insomniacs had abnormal MMPI values and were subjectively more confused, tense, depressed, and angry than matched normals. Sleep State Misperception insomniacs also had a significantly increased 24-hour metabolic rate, compared with matched normals. CONCLUSIONS: The overall increase in whole body oxygen use was less than that seen in psychophysiological insomniacs but was consistent with the view that Sleep State Misperception insomnia may be a mild version or a precursor to psychophysiological insomnia.

Morphine-like insomnia from heroin in nondependent human addicts.

1 This study was performed because dose-related effects of heroin on human sleep had not been described previously, and to discover if heroin produces a morphine-like insomnia. 2 After three adaptation nights, the sleep of seven male nondependent opiate addicts was studied following i.m. doses of heroin (3, 6, 12 mg/70 kg), morphine (10, 20 mg/70 kg) or placebo at weekly intervals in a randomized double-blind crossover design. 3 Heroin produces a dose-related increase in wakefulness, drowsiness episodes, muscle tension, and shifts in sleep-waking states. 4 Heroin produces a dose-related decrease in total sleep, sleep efficiency, delta sleep and REM sleep (REMS). 5 Heroin is about twice as potent as morphine in producing this type of insomnia. 6 'Morphine insomnia' appears to be a characteristic initial effect of several opioids, at least in nondependent opiate addicts, and might serve as a model insomnia for evaluation of hypnotics.

Disorders of the sleep-wake cycle in adults.

Adults have an intrinsic body clock which regulates a complex series of rhythms including sleep and wakefulness, fatigue and cognitive ability. This endogenous clock naturally runs more slowly than the solar day and is entrained to a 24-h rhythm primarily by the alternation of light and darkness. Jet lag, shift-work sleep disorder, and some of the chronic insomnias are caused by a temporal discrepancy of the body clock relative to the surrounding environment and social network. The underlying mechanisms and general management are described. Both bright light and melatonin therapy have potential in the management of these disorders. Traditionally, bright light therapy has been used to alleviate the depression associated with seasonal affective disorder. Melatonin has received much ill-formed publicity, it being claimed that it is a panacea and an 'antiageing' treatment. Both of these treatment approaches are reviewed.

Nocturnal psychophysiological correlates of somatic conditions and sleep disorders.

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.

Guidelines for prescribing melatonin.

Although compelling logic suggests that melatonin may be effective for a variety of disorders, there are few empirical clinical studies. The optimal dose of melatonin is not clear; most studies have used doses that produce supraphysiological blood levels. The timing of melatonin administration is important. Melatonin has few immediate side-effects except drowsiness, but the effects of chronic administration are unclear. Melatonin may be effective in reducing jet lag. In elderly patients with poor sleep and documented low melatonin production, melatonin may be helpful. In several studies, melatonin has been shown to shorten sleep latency. Further studies are needed to clarify the efficacy and safety of melatonin.
