Brief report: improvements in the behavior of children with autism following massage therapy.

Twenty children with autism, ages 3 to 6 years, were randomly assigned to massage therapy and reading attention control groups. Parents in the massage therapy group were trained by a massage therapist to massage their children for 15 minutes prior to bedtime every night for 1 month and the parents of the attention control group read Dr. Seuss stories to their children on the same time schedule. Conners Teacher and Parent scales, classroom and playground observations, and sleep diaries were used to assess the effects of therapy on various behaviors, including hyperactivity, stereotypical and off-task behavior, and sleep problems. Results suggested that the children in the massage group exhibited less stereotypic behavior and showed more on-task and social relatedness behavior during play observations at school, and they experienced fewer sleep problems at home.

Sleep disturbances in children with attention-deficit/hyperactivity disorder.

OBJECTIVE: To evaluate the relationship between sleep disturbances and attention-deficit/hyperactivity disorder (ADHD). METHOD: Empirical research published since 1970 on sleep disturbances in children with ADHD was systematically reviewed. A "box-score" approach was used to examine consistency of findings across the studies, which used different outcome measures. RESULTS: Although subjective accounts of sleep disturbances in ADHD were prevalent, objective verification of these disturbances was less robust. The only consistent objective findings were that children with ADHD displayed more movements during sleep but did not differ from normal controls in total sleep time. An additional finding was that stimulant medication led to changes in the children's sleep (e.g., prolonged sleep latency, increased length of onset to first rapid eye movement cycle), but these changes were believed to be nonpathological. CONCLUSIONS: The exact nature of the sleep problems in children with ADHD remains to be determined. Many of the relevant issues have not been adequately addressed. Factors such as poorly defined diagnostic groups, small sample sizes, few studies, and methodological and procedural limitations make it difficult to determine the relationship between ADHD and sleep problems.

The administration of psychotropic and anticonvulsant drugs to children with profound intellectual disability and multiple impairments.

A national (England and Wales) postal survey of families with a son or daughter with profound intellectual disability and multiple physical and sensory impairments who lived at home was undertaken. A section of the questionnaire dealt with prescription of major tranquillizers, drugs with a sedative function, anticonvulsants and stimulants, while among other variables information was also collected on sex, age, behaviour problems, sleep difficulties and epilepsy. Of children and adults: 5.3 and 7.9%, respectively, were receiving major tranquillizers; 28.5 and 24.5%, respectively, were prescribed drugs with a sedative function; and 53.4 and 52.7% were in receipt of anticonvulsants, with no individuals in receipt of stimulants. Only 1.5% of the total sample received major tranquillizers, drugs with a sedative function and anticonvulsants, though 18.9% were prescribed drugs from two classes, notably drugs with a sedative function and anticonvulsants. In all, 66.3% of the combined child and adult samples received at least one drug from the classes investigated. No sex bias in prescribing was found. Receipt of major tranquillizers bore some relation to reported behaviour problems, while administration of sedatives and anticonvulsants were related respectively to reports of sleep problems and occurrence of epilepsy.

Laboratory and field studies of naps and caffeine as practical countermeasures for sleep-wake problems associated with night work.

STUDY OBJECTIVES: To evaluate the effects of napping, caffeine, and napping plus caffeine on performance and alertness in both laboratory and field settings. DESIGN: (1) Laboratory Study: parallel-groups design with random assignment to 1 of 4 experimental conditions. (2) Field Study: crossover design. SETTING: Sleep laboratory and field settings. PARTICIPANTS: (1) Laboratory Study: 68 healthy individuals; (2) Field Study: 53 shiftworkers who worked nights or rotating shifts. INTERVENTIONS: (1) Laboratory Study: an evening nap opportunity before the first 2 of 4 consecutive simulated night shifts plus placebo taken all 4 nights, caffeine taken nightly, the combination of the nap and caffeine conditions, or placebo. (2) Field Study: an evening nap on the first 2 of 4 consecutive night shifts plus caffeine taken nightly versus placebo taken nightly without naps. MEASUREMENTS AND RESULTS: (1) Laboratory Study: Napping, caffeine, and their combination all improved alertness and performance as measured by Maintenance of Wakefulness Test and Psychomotor Vigilance Task, but the combination of napping and caffeine was best in improving alertness. (2) Field Study: Napping plus caffeine improved performance as measured by Psychomotor Vigilance Test and decreased subjective sleepiness in individuals working the night shift. CONCLUSIONS: Napping plus caffeine helps improve performance and alertness of night-shift workers.

Psychological reactions in patients with malignant melanoma.

Psychological and psychosomatic reactions to malignant melanoma were studied, comparing patients with tumour thickness < or = 0.8 mm versus > 0.8 mm and recurrent versus non-recurrent patients. Gender differences were also studied. Consecutive melanoma patients, Stage I (n = 144), were interviewed at their first postsurgery follow-up visit to an oncology clinic and completed questionnaires 7 and 13 months later. The questionnaire contained items regarding interest in nevi, sleeping problems, psychosomatic complaints, and the Hospital Anxiety and Depression Scale. Patients with a more unfavourable prognosis (tumour thickness > 0.8 mm), subjected to regular medical procedures, did not differ from those with a more favourable prognosis (< or = 0.8 mm), except reporting more sleeping problems. Women had considerably higher levels of problems than men. Amongst patients with an unfavourable prognosis, those with recurrence within 2 years showed lower levels of anxiety at the first visit compared with those free from recurrence after 2 years.

Evaluation of severe insomnia in the general population: results of a European multinational survey.

The epidemiology of severe insomnia and its effect on quality of life and healthcare consumption was assessed in a survey of the general population of five northern European countries. Applying established consumer sampling techniques, insomnia sufferers were selected from the general population using a questionnaire, conducted by face-to-face interview, and severity of insomnia was ranked (severe, mild/moderate, no sleep complaint) using a specific algorithm. Population samples were matched according to case control methodology for age, gender and geographical region. A second questionnaire gathered information on sleep problems, quality of life (SF-36 scores) and healthcare consumption. The prevalence of severe insomnia ranged from 4% to 22%, was higher in females than in males, but did not increase significantly with age. Patients with severe insomnia had been experiencing sleeping problems for a median of 2-6 years. In all countries, insomnia had a negative impact on quality of life, and the degree of impairment in quality of life was directly related to the severity of insomnia. Individuals with severe insomnia also showed a higher level of healthcare consumption. Despite this, severe insomnia did not appear to feature prominently in the doctor-patient relationship.

Population study of tender point counts and pain as evidence of fibromyalgia.

OBJECTIVE: To determine the relation between tender points, complaints of pain, and symptoms of depression, fatigue, and sleep quality in the general population. DESIGN: Two stage cross sectional study with an initial questionnaire about pain to classify those eligible for an examination of tender points. SETTING: Two general practices in north west England. SUBJECTS: Stratified random sample of adults from age-sex registers. Of the responders, 250 were selected for examination of tender points on the basis of their reported pain complaints; 177 subsequently participated. MAIN OUTCOME MEASURES: Tender point count (0 to 18) grouped into four categories with the highest (> or = 11) corresponding to the criteria of the American College of Rheumatology for fibromyalgia. Assessment of pain (chronic widespread, regional, none). Measures of depression, fatigue, and difficulty with sleeping. RESULTS: Women had a higher median tender point count (six) than did men (three). Counts were higher in those with pain than in those who had no pain and in those with widespread compared with regional pain. Most subjects with chronic widespread pain, however, had fewer than 11 tender points (27/45; 60%). Two people with counts of 11 or more were in the group reporting no pain. Mean symptom scores for depression, fatigue, and sleep problems increased as the tender point count rose (P value for trend < 0.001). These trends were independent of pain complaints. CONCLUSIONS: Tender points are a measure of general distress. They are related to pain complaints but are separately associated with fatigue and depression. Sleep problems are associated with tender points, although prospective studies are needed to determine whether they cause tenderness to develop. Fibromyalgia does not seem to be a distinct disease entity.

Sleep disturbances in patients with post-traumatic stress disorder: epidemiology, impact and approaches to management.

Subjective reports of sleep disturbance indicate that 70-91% of patients with post-traumatic stress disorder (PTSD) have difficulty falling or staying asleep. Nightmares are reported by 19-71% of patients, depending on the severity of their PTSD and their exposure to physical aggression. Objective measures of sleep disturbance are inconsistent, with some studies that used these measures indicating poor sleep and others finding no differences compared with non-PTSD controls. Future research in this area may benefit from examining measures of instability in the microstructure of sleep. Additionally, recent findings suggest that sleep disordered breathing (SDB) and sleep movement disorders are more common in patients with PTSD than in the general population and that these disorders may contribute to the brief awakenings, insomnia and daytime fatigue in patients with PTSD. Overall, sleep problems have an impact on the development and symptom severity of PTSD and on the quality of life and functioning of patients. In terms of treatments, SSRIs are commonly used to treat PTSD, and evidence suggests that they have a small but significant positive effect on sleep disruption. Studies of serotonin-potentiating non-SSRIs suggest that nefazodone and trazodone lead to significant reductions in insomnia and nightmares, whereas cyproheptadine may exacerbate sleep problems in patients with PTSD. Prazosin, a centrally acting alpha1-adrenoceptor antagonist, has led to large reductions in nightmares and insomnia in small studies of patients with PTSD. Augmentation of SSRIs with olanzapine, an atypical antipsychotic, may be effective for treatment-resistant nightmares and insomnia, although adverse effects can be significant. Additional medications, including zolpidem, buspirone, gabapentin and mirtazapine, have been found to improve sleep in patients with PTSD. Large randomised, placebo-controlled trials are needed to confirm the above findings. In contrast, evidence suggests that benzodiazepines, TCAs and MAOIs are not useful for the treatment of PTSD-related sleep disorders, and their adverse effect profiles make further studies unlikely. Cognitive behavioural interventions for sleep disruption in patients with PTSD include strategies targeting insomnia and imagery rehearsal therapy (IRT) for nightmares. One large randomised controlled trial of group IRT demonstrated significant reductions in nightmares and insomnia. Similarly, uncontrolled studies combining IRT and insomnia strategies have demonstrated good outcomes. Uncontrolled studies of continuous positive airway pressure for SDB in patients with PTSD show that this treatment led to significant decreases in nightmares, insomnia and PTSD symptoms. Controlled studies are needed to confirm these promising findings.

Factors related to current and subsequent psychotropic drug use in an elderly cohort.

AIMS OF THE STUDY: The purpose of this study was to estimate the prevalence of psychotropic drug use in a cohort of elderly persons and to examine factors related to current and subsequent drug use. POPULATION: A representative cohort of non-institutionalized subjects aged 65 and over living in New Haven, Connecticut, was interviewed in 1982, and again in 1985 and 1988. Psychotropic drug use during the prior two weeks was assessed at each home interview. RESULTS: At the baseline interview in 1982, 12.3% of the subjects reported using psychotropic drugs, half of them (6.25%) benzodiazepines. In multivariate analyses, psychotropic drug use was significantly associated with female gender and white ethnicity but not with older age. Psychotropic drug use and depressive symptomatology were strongly correlated in both genders. However, less than 5% of the subjects reporting high depressive symptomatology were using antidepressants. Psychotropic drug use was also associated with sleep problems in men and medical conditions in women. Psychotropic drug consumption increased slightly to 15.1% in 1988. Continuous use (use reported in 1982, 1985 and 1988) was found in 4.5% of the sample; it was strongly related to both depressive symptomatology and sleep problems reported at baseline. New use, beginning either in 1985 or in 1988, was observed in 12.6% of the sample; it was related to female gender, older age, and, among baseline health variables, to depressive symptomatology. CONCLUSIONS: Prevalence of psychotropic drug use in this cohort of elderly people was lower than in other studies conducted in the U.S. The reasons for this variation are discussed. Continuous use was not higher for benzodiazepines than for other psychotropic drugs.

Evaluation of L-tryptophan for treatment of insomnia: a review.

Sleep laboratory and outpatient studies of the hypnotic efficacy of the amino acid L-tryptophan are reviewed, with particular emphasis on evaluation of therapeutic effectiveness in the treatment of insomnia. In younger situational insomniacs, whose sleep problem consists solely of longer than usual sleep latencies, L-tryptophan is effective in reducing sleep onset time on the first night of administration in doses ranging from 1 to 15 g. In more chronic, well-established sleep-onset insomnia or in more severe insomnias characterized by both sleep onset and sleep maintenance problems, repeated administration of low doses of L-tryptophan over time may be required for therapeutic improvement. In these patients, hypnotic effects appear late in the treatment period or, as shown in some studies, even after discontinuation of treatment. The improvement in sleep measures post-treatment has given rise to use of a treatment regimen known as "interval therapy", in which L-tryptophan treatment alternates with an L-tryptophan-free interval until improvement occurs. The absence of side effects and lack of development of tolerance in long-term use are important factors in the decision to embark upon a trial of L-tryptophan treatment. In addition, L-tryptophan administration is not associated with impairment of visuomotor, cognitive, or memory performance, nor does it elevate threshold for arousal from sleep.

The relationship between hand preference consistency, health, and accidents in a sample of adults over the age of 65 years.

As a result of the Coren and Halpern (1991) hypothesis that left hand preference may be associated with decreased survival fitness, there has been interest in exploring the relationship between hand preference and indices of health status. In a series of studies of university-aged adults, Hicks and his colleagues found a higher prevalence of accidental injuries, falls, and sleep problems among individuals with mixed, rather than left, hand preference. They argued that hand preference consistency, not side, may be a marker for possible reduction in health and well-being. We looked at the relationship between hand preference consistency and the prevalence of sleep problems, accidental injuries, falls, injuries from falls, and the prevalence of autoimmune and other illnesses in a sample of 1277 adults between the ages of 65 and 100 years. Of those participants who reported a recent fall, mixed-handers were more likely to report a higher number of injuries from these falls when compared to the reports of consistent-handers. In contrast to the previous findings of Hicks et al., and highlighting the value of including broader age ranges, all other comparisons showed no differences between the two hand preference types.

Leisure time, physical activity and some indices of mental health.

In the introduction the concept of health is discussed. The author emphasizes that the concept of health is often used in a biased and uncritical manner in discussions on the value of physical activity in relation to health. The practice of physical activity should be seen in relation to a more holistic concept of health, defined as a human being's total ability to function. Results are then presented from a number of investigations, of which the majority indicate a positive relation between physical activity and a reduction in the following indices of mental health: anxiety, depression, nervousness, sleep problems emotional instability and general fatigue. This particularly applies however to persons who at the onset are in especially poor physical and mental condition. In conclusion the results of a nationwide investigation conducted by the author are discussed. The indices of mental health used were sleep problems, nervous disorders and overexertion. Physically active persons over 50 years old have better mental health than physically passive ones. However a corresponding difference was not found in younger age groups. The article attempts to show what we "know" about the relationship between the practice of physical activity and some aspects of mental health.

Sleep and adolescent suicidal behavior.

STUDY OBJECTIVES: Suicide risk begins to increase during adolescence. Adolescents do not get enough sleep and are also at risk for many sleep disturbances. This study examined the association between sleep patterns and sleep problems and adolescent suicidal behavior. DESIGN AND SETTING: A questionnaire survey of adolescents attending school was conducted in one prefecture of Shandong Province, People's Republic of China. PARTICIPANTS: A total of 1,362 adolescents attending school (mean age 14.6 years, 60% males) participated in the survey. MEASUREMENTS: Respondents completed a self-administered questionnaire that asked about sleep patterns, sleep problems, suicidal behavior, depressive symptoms, and demographic characteristics of the family and adolescent. RESULTS: Overall, 19.3% of the sample reported having suicidal ideation, 10.5% having suicide attempts in the past 6 months, 16.9% having insomnia symptoms, 2.3% having taken hypnotic medication, and 48.9% having experience of nightmares in the past month. Mean night sleep duration was 7.6 hours (SD = 0.8). Logistic regression analyses showed that sleeping less than 8 hours at night (OR = 2.89, 95% confidence interval [CI] = 1.07-7.81) and frequent nightmares (OR = 2.43, 95% CI = 1.76-3.35) were significantly associated with increased risk for suicide attempts after adjustment for age, sex, father's occupation, and depressive symptoms and that nightmares (OR = 1.69, 95% CI = 1.20-2.38) were also significantly related to suicidal ideation. CONCLUSION: These findings demonstrate the association between short sleep duration and nightmares and suicidal behavior and highlight the potential role of sleep intervention in the prevention of adolescent suicide.

Predictors of future depression in early and late adolescence.

BACKGROUND: This study examined whether the possibility to predict future DSM-IV depressive disorder can be increased with recurrent screening for depression in community adolescents, compared to single screening in early or in late adolescence. In addition, it examined which depressive symptoms in early and late adolescence predicted future depressive disorder most accurately. METHODS: Participants from an ongoing longitudinal cohort study were assessed when they were aged between 10 and 15 (early adolescence), and between 14 and 19 (late adolescence), and were followed until they were 20-25 (young adulthood). The Child Behavior Checklist (CBCL) and Youth Self-Report (YSR) were used to screen for depression in early and late adolescence, and CIDI/DSM-IV diagnoses of depressive disorder were used as the outcome measure during follow-up. RESULTS: Recurrent screening only slightly improved the prediction of future depression, and cognitive and physical symptoms in late adolescence predicted future depression accurately in boys. Sleeping problems in early adolescence predicted future depression in girls. LIMITATIONS: The main limitation was the retrospective recall of the age of onset of a depressive disorder. CONCLUSIONS: Recurrent screening for depression did not predict future depressive disorder better than single screening in late adolescence. However, depressive symptoms like sleeping problems predicted future depression quite accurately in adolescent boys and girls. This indicates that it may be useful to screen adolescents for the presence of such symptoms, for instance in school settings, to predict which adolescents are at risk to develop DSM-IV depressive disorder in early adulthood.

The Importance of Residual Effects When Choosing a Hypnotic: The Unique Profile of Zaleplon.

BACKGROUND: Insomnia is a prevalent medical disorder that has significant effects on occupational performance, health, and quality of life. Insomnia places an enormous burden on society through increased visits to physicians, loss of productivity in the workplace, and an increased rate of accidents. An estimated sum of $100 million is spent each year on direct treatment of unresolved insomnia. Physicians need to initiate early effective treatment to prevent development of chronic insomnia and its associated morbidity. Institution of good sleep hygiene practices may be useful in some patients but may not be adequate for resolution of all sleep problems. Behavioral treatments, while effective and durable, are time consuming and not widely utilized in clinical practice. Pharmacotherapy includes benzodiazepine hypnotics, but concerns regarding adverse effects (e.g., residual sedation) prompted the search for safer options. DATA SOURCES: Published and presented studies containing clinical data on zaleplon, a new nonbenzodiazepine sleep medication, were identified via MEDLINE, Current Contents (ISI database), bibliographic reviews, and consultation with sleep specialists. RESULTS: Zaleplon effectively shortens sleep onset time and improves the quality of sleep in patients with insomnia. Whether administered at bedtime or later at night, zaleplon is devoid of residual sedative effects that impair next-day functioning. Follow-up studies evaluating the long-term efficacy and safety of zaleplon showed that decreased time to sleep onset was maintained during therapy lasting up to 52 weeks, without a withdrawal syndrome after discontinuation. CONCLUSION: Insomnia is recurrent and unpredictable in nature. Despite the long-term morbidity of this sleep disorder, research evidence and practice guidelines have not explored long-term use of hypnotics. Many patients could benefit from long-term drug therapy with a sleep medication that is devoid of residual effects and can be taken at bedtime or later as symptoms occur, rather than nightly in anticipation of a sleep problem.

Comorbid subjective health complaints in low back pain.

STUDY DESIGN: Cross-sectional study. OBJECTIVES: To compare subjective health complaints in subacute patients with low back pain with reference values from a Norwegian normal population. SUMMARY OF BACKGROUND DATA: Comorbidity is common with nonspecific low back pain. We wanted to investigate if these complaints were specific or part of a more general unspecific condition comparable to subjective health complaints in the normal population. MATERIALS AND METHODS: The study group consisted of 457 patients sick-listed 8 to 12 weeks for low back pain. All subjects filled out questionnaires. The subjective health complaints in the study group were compared with reference values from a Norwegian normal population using logistic regression analysis. RESULTS: Compared with the normal reference population, the patients with low back pain had significantly more low back pain, neck pain, upper back pain, pain in the feet during exercise, headache, migraine, sleep problems, flushes/heat sensations, anxiety, and sadness/depression. The prevalence of pain in arms, pain in shoulders, and tiredness was also high, but not significantly higher than in the reference population. CONCLUSIONS: Our findings indicate that patients with low back pain suffer from what may be referred to as a "syndrome," consisting of muscle pain located to the whole spine as well as to legs and head, and accompanying sleep problems, anxiety, and sadness/depression.

A comparison of different psychosocial questionnaires in patients with myocardial infarction.

In a consecutive study of 140 patients investigated one month after myocardial infarction (MI), a battery of American and English questionnaires was used to measure depression, anxiety, sleep problems, health locus of control and perceived health. These measures were compared with a well-documented generic questionnaire, the Nottingham Health Profile (NHP), and a similarly well-documented mood scale, the Mood Adjective Check List (MACL). There was close agreement among all measures depicting anxiety and tension. The concordance between the measures of anxiety states and depression was lower. Depression and sleep problems seem to constitute separate concepts, since they are not as highly related to the other measures of anxiety. Because psychosocial factors are important measures for the outcome after an infarction, accurate assessments of these variables are required. Further research is clearly warranted to clarify the complicated interaction between psychosocial constructs and to improve the methods used for their evaluation.

Predicting completeness of symptom relief after major heart surgery.

The authors hypothesized that the same biopsychosocial factors that raise the risk of illness incidence would influence the speed and completeness of relief from physical symptoms during recovery following cardiac surgery. This multicenter prospective study involved 463 patients aged 35 to 69 years who underwent coronary artery bypass graft or cardiac valve surgery. Predictor data were gathered 1 to 3 days before surgery, and outcome measures were collected 6 months postoperatively. The following predictors were associated with postoperative freedom from cardiac symptoms: fewer preoperative cardiac hospitalizations; low levels of angina, dyspnea, fatigue, and sleep problems; low levels of anxiety, depression, hostility, and life-change events; and high levels of psychosocial well-being, hopefulness, overall satisfaction, and social support. The predictors of not requiring daytime bed rest because of cardiac symptoms during the 6th postoperative month were male gender, higher education, less cardiac disability preoperatively, low levels of angina, dyspnea, sleep problems, depression and fatigue, and absence of Type A behavior and of intraoperative hypotension. By using separate multiple logistic regression equations, the authors identified the variables printed in bold face as independent significant contributors to prediction. Many of the predictors are strong enough and simple enough to be used in clinical practice. Many of them may also predict recovery after acute illnesses and injuries involving other organ systems.
