Sleep-related problems of Parkinson's disease.

OBJECTIVE: To define the epidemiology, characteristics and aetiology of nocturnal symptoms and sleep disorders in patients with Parkinson's disease (PD) and evaluate the available methods for their diagnosis and management. METHODS: A review of the English-language literature pertaining to sleep disturbances associated with PD, using the Medline database and bibliographies in relevant articles. RESULTS: Sleep-related problems specific to PD may occur early and even predate the diagnosis of the disease but are generally more frequent and more severe in patients with advanced PD. These problems can seriously compromise patients' quality of life and lead to impaired functioning in daily activities. Scales designed specifically for the assessment of sleep problems in patients with PD have recently been developed. Evidence base for the treatment of sleep disturbances in PD is poor, and only nocturnal akinesia, excessive day-time sleepiness and rapid eye movement behaviour disorder have been partially addressed. CONCLUSIONS: Sleep disorders associated with PD are a common and under-recognised problem. The assessment of sleep should be part of the routine evaluation of patients with PD, and large-scale controlled therapeutic trials are necessary.

A comparison of reported sleep disorders in patients on chronic hemodialysis and continuous peritoneal dialysis.

There are few data about the prevalence and characteristics of reported sleep disorders in chronic dialysis patients and, although insomnia is often used as a marker of uremia, there are few data relating complaints of sleep to adequacy of dialysis. We therefore surveyed 48 hemodialysis (HD) patients, 22 continuous peritoneal dialysis (PD) patients, and 41 healthy control subjects about disordered sleep. The questionnaire included demographic data, questions characterizing the reported sleep problems, and linear analogue scales quantitating the severity of the sleep disturbance and feelings of anxiety, worry, and sadness. Kt/V determinations were also made for each dialysis patient. Fifty-two percent of the HD, 50% of the PD, and 12% of the control subjects reported problems sleeping (P less than 0.001, all dialysis patients v controls). No differences between HD and PD in characteristics of sleep problems were seen. Sleep severity scale results confirmed sleep disorders (7.2 in those with v 0.95 in those without sleep disorders, where 0 = sleep a little problem and 10 = a big problem, P less than 0.001). Caffeine intake (P less than 0.05) and worry (P less than 0.004) were the only factors associated with reported sleep disturbances. Kt/V values (1.4 +/- 0.3) did not predict reported sleep problems. Mean reported hours of sleep per night (5.5 +/- 2 v 5.8 +/- 1.4) and desired hours of sleep per night (8.3 +/- 2 v 7.6 +/- 1.3) were similar among dialysis patients and controls reporting sleep problems. Dialysis patients and controls without self-reported sleep disorders slept a mean of 7.1 +/- 2.4 and 7 +/- 1.1 h/night, respectively.(ABSTRACT TRUNCATED AT 250 WORDS)

The association between disease severity and sleep-related problems in patients with Parkinson's disease.

Although sleep-related problems are a frequent finding in patients with Parkinson's disease (PD), the aetiology is still unknown. We examined the associations between disease severity, sleep-related problems and social status in 116 PD patients participating in the FAQT Study, a prospective, German cohort study evaluating determinants of quality of life in PD patients. 47.4% of the patients reported sleep onset difficulties, 26.7% sleep interruptions, 14.7% had five or more sleep-related events during the night and 71.6% showed symptoms of increased daytime somnolence. The disease severity was significantly associated with sleep-related events (p = 0.01), the depression score with sleep onset difficulties (p = 0.04), sleep interruptions (p = 0.01) and the levodopa dose (p < 0.01). We conclude that depressive symptoms and increasing levodopa doses in PD patients mainly cause sleep onset difficulties and sleep interruptions, while the severity of motor symptoms contributes to sleep-related events like sleep walking, heavy sweating and nightmares.

Neuroticism and sleep-related problems in adolescence.

STUDY OBJECTIVE: To examine the relationship between neurotic personality characteristics and sleep habits/problems. DESIGN: A population-based cross-sectional study. SETTING: NA. PARTICIPANTS: Nine hundred sixty five students from two junior high schools in Taipei and their parents were randomly selected in December 1993 for inclusion in the study. The response rate was 96.4% (930) for students and 88.6% (855) for parents. INTERVENTIONS: NA. MEASUREMENTS AND RESULTS: Students were administered a sleep habit questionnaire and the Junior Eysenck Personality Inventory (JEPI) at both junior high schools in Taipei. For the JEPI, high and low neuroticism was operationally defined as scores that were one or more standard deviation above or below the sample mean, respectively. This yielded two extreme groups: high neuroticism group (n=183) and low neuroticism group (n=163). The high neuroticism group went to bed later and slept less than did the low neuroticism group. Using logistic regression, adjusting for sex and years at junior high school, the high neuroticism group had significantly different sleep habits and school performance from the low neuroticism group. Subjects in the high neuroticism group had significant risk of feelings of sleep insufficiency, tiredness, moodiness, and difficulty waking up in the morning; they also had more daytime sleepiness than did those in the low neuroticism group. The high neuroticism group also suffered from more sleep-related problems than did the low neuroticism group. CONCLUSIONS: The findings support the hypothesis that a high neuroticism score is associated with going to bed late on school days, short sleep duration, different sleep habits, sleep problems, and impaired daytime function in comparison with a low neuroticism score.

Associations between disturbed sleep and behavioural difficulties in 635 children aged six to eight years: a study based on parents' perceptions.

Associations between sleep and behaviour in 635 children, aged six to eight years, were investigated using parental responses to a sleep habits questionnaire, and to a behavioural screening form, the Strengths and Difficulties Questionnaire (SDQ). Global reports of sleep problems in 4.9% of the children were associated with a total SDQ score indicative of behaviour problems in 36% of the cases. Conversely, 15% of children with behaviour problems had global reports of sleep problems. Associations between specific sleeping features and different dimensions of behaviour and emotions were also explored. Hyperactivity was associated with tossing and turning during sleep, and with sleep walking; conduct problems were related to bedtime resistance; and emotional symptoms were associated with night terrors, difficulty falling asleep and daytime somnolence. Peer problems were associated with somewhat shorter total sleep time. Finally, a total SDQ score indicative of behaviour problems was associated with bedwetting, nightmares, tossing and turning during sleep and sleep walking, as well as with a slightly shorter total sleep time. We conclude that sleep and behaviour problems are associated in children, and that characteristic associations exist between particular sleep disturbances and specific dimensions of behaviour.

Sleep disruption in young children. The influence of temperament on the sleep patterns of pre-school children.

Sleep problems are a common concern of parents with toddlers. Various reasons have been put forward as to the possible causes and maintenance of sleep disruption. These have included neurophysical differences in the child, perinatal differences such as a long labour and depression and anxiety in the parents themselves resulting in adverse effects on the child's sleep patterns. However, recent research has indicated that a child's temperamental style may be a possible causal factor as to whether the child will present its parents with a sleep problem. This study, therefore, sets out to investigate the importance of temperament as a predictor of whether children may or may not have sleep problems. Environmental factors are controlled as far as possible by selecting toddlers with and without sleep problems from very similar environments. Case studies are also introduced to further illuminate other possible associated factors such as parental handling. The results from this study found significant differences in the temperament profiles of children with and without sleep problems. Children with reported sleep problems were more likely to obtain a 'intermediate high to difficult' profile. Various findings from a group of toddlers with and without sleep problems are discussed in this paper together with implications of the findings and recommendations for further research.

Randomised controlled trial of behavioural infant sleep intervention to improve infant sleep and maternal mood.

OBJECTIVE: To compare the effect of a behavioural sleep intervention with written information about normal sleep on infant sleep problems and maternal depression. DESIGN: Randomised controlled trial. SETTING: Well child clinics, Melbourne, Australia. PARTICIPANTS: 156 mothers of infants aged 6-12 months with severe sleep problems according to the parents. MAIN OUTCOME MEASURES: Maternal report of infant sleep problem; scores on Edinburgh postnatal depression scale at two and four months. INTERVENTION: Discussion on behavioural infant sleep intervention (controlled crying) delivered over three consultations. RESULTS: At two months more sleep problems had resolved in the intervention group than in the control group (53/76 v 36/76, P=0.005). Overall depression scores fell further in the intervention group than in the control group (mean change -3.7, 95% confidence interval -4.7 to -2.7, v -2.5, -1.7 to -3.4, P=0.06). For the subgroup of mothers with depression scores of 10 and over more sleep problems had resolved in the intervention group than in the control group (26/33 v 13/33, P=0.001). In this subgroup depression scores also fell further for intervention mothers than control mothers at two months (-6.0, -7.5 to -4.0, v -3.7, -4.9 to -2.6, P=0.01) and at four months (-6.5, -7.9 to 5.1 v -4.2, -5.9 to -2.5, P=0.04). By four months, changes in sleep problems and depression scores were similar. CONCLUSIONS: Behavioural intervention significantly reduces infant sleep problems at two but not four months. Maternal report of symptoms of depression decreased significantly at two months, and this was sustained at four months for mothers with high depression scores.

The practice of pediatric sleep medicine: results of a community survey.

OBJECTIVE: To assess knowledge, screening, evaluation, treatment practices, and attitudes regarding sleep disorders in children and adolescents in a large sample of community-based and academic pediatricians. DESIGN: Cross-sectional survey. PARTICIPANTS: Six hundred twenty-six pediatricians in Rhode Island, Massachusetts, and Connecticut. INTRUMENT: The Pediatric Sleep Survey, a 42-item questionnaire assessing general and specific sleep knowledge categories; clinical screening, diagnostic, and treatment practices for common pediatric sleep disorders; and practitioner attitudes regarding the impact of sleep disorders in the clinical setting and as a public health issue. RESULTS: On the knowledge section, the mean Total Knowledge score for the respondents was 18.1 +/- 3.5 out of 30 items, with 23.5% of the sample responding correctly on half or less of the items. Pediatricians scored highest on items relating to developmental and behavioral aspects of sleep and parasomnias, whereas the mean percentage of correct responses was <50% for items relating to sleep disordered breathing, excessive daytime sleepiness, and sleep movement disorders. Although only 16.5% and 18.2% of the sample reported not screening routinely for sleep disorders in infants and toddlers, this percentage rose to 43.9% in adolescents. Furthermore, only 38.3% regularly question the adolescents themselves about their sleep. Only about one quarter of the respondents screen toddlers and school-aged children for snoring. In evaluating and treating pediatric sleep problems, 53.2% of the sample never or rarely order overnight sleep studies to assess for obstructive sleep apnea and few use alternative treatment strategies, such as continuous positive airway pressure. A quarter of the sample at least occasionally recommends diphenhydramine and almost half suggests a psychological evaluation for children with night terrors. Finally, the percent of pediatricians rating the impact on children of sleep problems in a variety of domains as important or very important ranged from 49.7% (nonintentional injuries) to 92.6% (academic performance). However, only 46% of the sample felt confident or very confident about their own ability to screen for sleep problems, whereas 34.2% and 25.3% similarly rated their ability to evaluate and treat sleep problems in children. CONCLUSIONS: The results of this survey suggest that there are still significant gaps among practicing pediatricians both in basic knowledge about pediatric sleep disorders, and in the translation of that knowledge into clinical practice. Despite their acknowledgment of the importance of sleep problems, many pediatricians fail to screen adequately for them, especially in older children and adolescents. Additional educational efforts regarding pediatric sleep issues are warranted, and should be targeted at the medical school, postgraduate training, and continuing medical education levels.

Sleep disorders and illness intrusiveness in patients on chronic dialysis.

BACKGROUND: The prevalence of sleep problems (insomnia, restless legs syndrome, periodic limb movements in sleep and sleep apnoea) has been shown to be high in patients with end-stage renal disease (ESRD) and might contribute to impaired quality of life in this population. METHODS: In a cross-sectional study using self-administered questionnaires, we examined the prevalence of sleep disorders and assessed their effect on different aspects of health-related quality of life in a sample of Hungarian patients on maintenance dialysis. RESULTS: Our data confirm that sleep problems are frequent in patients with ESRD; 65% of the patients reported symptoms of at least one specific sleep disorder; insomnia was the most common sleep complaint with 49%, the prevalence of sleep apnoea was 32% and the prevalence of restless legs syndrome was 15%. Co-morbidity, assessed by the End-Stage Renal Disease Severity Index, was shown to be an independent predictor of sleep disorders. Patients with sleep disorders reported higher illness intrusiveness and worse self-perceived health than those without sleep problems. The presence of sleep disorders was an independent predictor of illness intrusiveness, an important determinant of health-related quality of life. CONCLUSION: Sleep disorders are important determinants of illness intrusiveness and health-related quality of life in patients with ESRD. Sleep problems may be treated successfully; therefore, more attention should be paid to assessing these problems in this patient population.

Prevalence of insomnia in a survey of 12,778 adults in France.

This study was an epidemiological questionnaire survey of a representative sample of the French population that included 12 778 individuals and in which adapted DSM-IV criteria for the definition of insomnia were used. Our goals were not only to assess the prevalence of 'insomnia' using these criteria, but also to compare the results obtained with those of prior studies using different definitions of 'insomnia'. The aim of this study was also to identify where areas of agreement and disagreement existed, as we believe that it is important to emphasize these points because DSM-IV recommendations are supposedly reflected in clinical practice. Seventy-three per cent of the individuals surveyed complained of a nocturnal sleep problem, but only 29% reported at least one sleep problem three times per week for a month, and 19% (2428 subjects) had at least one sleep problem three times per week for a month and complained of daytime consequences (DSM-IV criteria). Only 9% had two or more nocturnal sleep problems with daytime consequences and were classified as 'severe insomniacs'. Our study indicates that if DSM-IV criteria are used, the diagnosis of 'insomnia' is lower than in other epidemiological studies. The DSM criteria have an advantage in that they emphasize the daytime consequences of nocturnal sleep disturbances, which seem to be responsible for the most important socio-economic costs of the problem.

Impaired sleep and rhythms in persons with cancer.

This review includes research findings from sleep-related studies on specific types of cancers, on specific types of treatment protocols, and on persons with end-stage cancer regardless of treatment protocol. Since treatment protocols have evolved in the past decade, literature since 1990 is emphasized. We conclude that researchers should design studies that attend to prior sleep history, gender, type of cancer and treatment modalities, and the specific type of sleep problems experienced over the course of diagnosis, treatment, and recovery. More research is also needed to understand sleep problems in children with cancer and sleep problems in family caregivers. Research is also needed on effective pharmacological and non-pharmacological interventions. Daytime functioning, daytime sleepiness, and altered circadian rhythms should be considered salient outcomes in addition to severity of cancer-related fatigue. Clinicians should consider whether a patient's sleep problem has been chronic and unrelated to cancer, or precipitated by diagnosis and treatment. The specific type of sleep problem should be ascertained so that appropriate interventions can be prescribed. Appropriate interventions can include either pharmacological medication or behavioral strategies, and each has the potential to promote restorative sleep and thereby improve the patient's quality of life, daytime functioning, and well-being.

Nocturia: impact on quality of life in a Dutch adult population.

OBJECTIVE: To estimate the effect of nocturia on quality of life (QoL) and to assess the associated effects of sleep problems. SUBJECTS AND METHODS: From a random sample of Dutch adults (>/= 18 years old) 1000 were selected after stratification to complete a written questionnaire. Respondents (819) were distributed over three groups: a target group (189, who felt bothered by >/= one void/night); a reference group 1 (120 reporting >/= two voids/night but with no bother); and reference group 2 (510, with 0-1 voids/night). Nocturia, other lower urinary tract symptoms and perceived impact on life were measured using the Bristol Lower Urinary Tract Symptoms Questionnaire (B-LUTS). Sleep problems were measured using the Sleep Wake Experience List (SWEL) and QoL using two subscales from the RAND-36, i.e. 'physical functioning' and 'mental health'. RESULTS: The perceived impact on life was highest in the target group (P < 0.05), which also had more sleep problems and scored lower on the QoL scores than both reference groups (P < 0.05). Statistically significant differences in mental health and physical functioning between the target and reference groups became insignificant after correcting for sleep problems, indicating that the effect of nocturia (with bother) is mediated by sleep problems. CONCLUSIONS: Nocturia may lead to sleep insufficiency and consequently to a decrease in mental and physical health. Patients who consult a doctor for nocturia should thus be treated adequately. In addition, it is worthwhile for doctors to routinely check if patients who contact them for sleep problems also have nocturia.

Severe sleep disturbance and daytime challenging behaviour in children with severe learning disabilities.

Sleep problems are common in children with severe learning difficulties. Children with sleep problems are reported to have more behaviour problems, but daytime challenging behaviour has not been examined specifically. The current study was concerned with associations between sleep problems and challenging behaviour, as well as describing other clinical features of the childrens' sleep, as reported by parents. All children in the series showed some form of sleep disturbance, with settling problems, night waking and early waking in 44% of the sample. Children with sleep problems showed significantly more types of challenging behaviour and challenging behaviour of a greater severity than children without sleep problems, resulting in management difficulties for carers throughout the 24-h period. Reasons for this association and suggestions for intervention are discussed.

Coping with sleep disturbances among young adults: a survey of first-year college students in Taiwan.

Sleep problems are highly prevalent among young adults and affect different aspects of their quality of life. In this study, the authors aimed to investigate the young adults' coping strategies for these sleep disturbances and the effectiveness of the coping strategies upon sleep quality and daytime sleepiness. The subjects included 1,922 first-year college students, 44% of whom reported experiencing sleep problems, with insufficient sleep being the most common complaint (23.9%). Taking naps and adjusting sleep schedules were the coping strategies associated with better sleep quality. On the other hand, subjects who reported attempting a sleep-promoting activity, ignoring their sleep problems altogether, or trying unsuccessfully to find a way of coping with their sleep problems reported a poorer sleep quality. Although some coping strategies were associated with better sleep quality than others, the levels of daytime sleepiness were equally impaired in all coping groups to a degree that is equivalent to the sleepiness in patients with a moderate sleep-related breathing disorder.

Sleep and behavior problems in school-aged children.

OBJECTIVES: The primary purposes of the present study were to survey the prevalence of sleep problems in school-aged children and to examine these associations with parental perception of sleep problems, medical history, and childhood psychopathology. METHODS: Sleep and medical history questionnaires and the Child Behavior Checklist were administered to the parents of 472 children between ages 4 and 12 years receiving routine pediatric care from urban, rural, and suburban pediatric practices. RESULTS: Although sleep problems were reported for 10.8% of the sample during the past 6 months, less than one half of the parents who identified sleep problems reported that they had discussed sleep with their child's pediatrician. The best predictor of current sleep problems was a history of sleep problems before age 2 years. Sleep problems such as snoring, tiredness during the day, and taking excessive time to fall asleep were very common, occurring at least 1 night per week in over 20% of the total sample. Factor analysis of the sleep problems questionnaire resulted in 5 sleep problem factors that accounted for 58.7% of the variance. Specific sleep problem factors include: parasomnias, enuresis/gags, tiredness, noisy sleep, and insomnia. Sleep problem factor scores were differentially associated with medical history variables and measures of childhood psychopathology. Children rated highly on parasomnias were more likely to have frequent falls and to display pica. Parasomnias and noisy sleep were inversely associated with socioeconomic status (SES). Children from lower SES families were rated higher on these factors than children from higher SES families. Enuresis/gags was the only sleep problem factor associated with age. Younger children scored higher on this factor. Duration of naps was highly correlated with age and with bed times during the week and weekends. As expected, younger children were more likely to nap for longer periods and to have earlier bed times. In addition, higher tiredness factor scores were associated with napping and with later bed times during the week and weekend. Boys were much more likely than were girls to have higher scores on enuresis/gags, and higher enuresis/gags scores were associated with an increased prevalence of trauma and falls. Bed times were not associated with any other sleep problem factor score. Children rated highly on tiredness were more likely to have a history of hospitalizations. Tiredness factor scores were strongly associated with the sleep practice of sharing a bed but not with sharing a room. Sharing a room was not associated with any sleep problem factor score. High scores on noisy sleep were associated with allergies, falls frequently, and with sharing a bed. Children with high scores on the insomnias were also more likely to display an increased prevalence of allergies. CONCLUSIONS: Parental perception of global sleep problems was surprisingly common in school-aged children receiving routine pediatric care. Parental reports of their children's sleep problems may be a red flag for specific sleep problems and psychiatric, social, or medical problems. Sleep problems should be queried about during pediatric visits for school-aged children.

[Sleep disorders in children with attention-deficit hyperactivity disorder--results of a polysomnographic study].

OBJECTIVES: We report results of a polysomnographic study carried out with children aged 6 to 12 years with either ADHD or a sleep disorder. The study focussed on whether the sleep structure and architecture of n = 36 ADHD children with and without sleep disorders differed from that of either n=15 children with sleep disorders or n=87 children without sleep disorders. Moreover, we assessed whether there was an increased risk for co-morbid sleep-related breathing disorders among ADHD children. METHODS: All children underwent polysomnography in a paediatric clinic. Principal variables of the sleep structure and architecture as well as cardiorespirographic measures were analysed. RESULTS: Our findings demonstrate that sleep problems in children with ADHD seem to be unspecific concurrent symptoms since the sleep structure of sleep-disordered ADHD children and children with sleep disorders was similar. Only minor differences were found between non-sleep-disturbed ADHD children and healthy children without sleep problems. CONCLUSIONS: We conclude that sleep problems in ADHD are independent co-morbid symptoms without any pathogenetic relationship to vigilance functions in ADHD. The cardiorespirographic analyses showed that a subgroup of ADHD children with sleep problems may be at increased risk for co-morbid sleep-related breathing disorder. This finding is potentially important for differential diagnostic considerations in ADHD.

Melatonin in older people with age-related sleep maintenance problems: a comparison with age matched normal sleepers.

STUDY OBJECTIVES: To determine whether older people with age-related sleep maintenance problems have significantly lower melatonin levels than comparable normal sleepers. DESIGN: Case-control study. SETTING: A largely urban population, Auckland, New Zealand. PARTICIPANTS: People over the age of 65 years, who either slept normally, or had age-related sleep maintenance problems. Participants were recruited through media advertising, and local interest groups. Initial screening was by mail (Pittsburgh Sleep Quality Index), followed by interviews at a hospital day clinic. Exclusions included those with depression, cognitive impairment, medical and/or environmental problems which might impair sleep. INTERVENTIONS: N/A. MEASUREMENTS AND RESULTS: A metabolite of plasma melatonin, 6-sulphatoxymelatonin (aMT6s) was measured in the urine of 57 normal sleepers, and 53 people with age-related problems over 24 hours in three aliquots: 12:00-19:00h, 19:00-07:00h, 07:00-12:00h. There were clear differences in self reported quality of sleep but no difference in mean aMT6s 24 hour or total night excretory levels, or night/day ratios. CONCLUSIONS: Older people with age-related sleep maintenance problems do not have lower melatonin levels than older people reporting normal sleep.
