Abstract
This investigation was designed to determine the effect of melatonin supplementation on mental health parameters, metabolic and genetic profiles in patients under methadone maintenance treatment (MMT). This randomized, double-blind, placebo-controlled, clinical trial was conducted among 54 patients under MMT. Participants were randomly allocated to receive either 10 mg melatonin (2 melatonin capsules, 5 mg each) (n = 26) or placebo (n = 28) once a day, 1 hour before bedtime for 12 weeks. Melatonin supplementation significantly decreased Pittsburgh Sleep Quality Index (β -4.08; 95 percent CI, -5.51, -2.65; P < 0.001), Beck Depression Inventory index (β -5.46; 95% CI, -8.92, -2.00; P = 0.003) and Beck Anxiety Inventory index (β -3.87; 95% CI, -5.96, -1.77; P = 0.001) and significantly increased International Index of Erectile Functions (β 5.59; 95% CI, 1.76, 9.42; P = 0.005) compared with the placebo. Subjects who received melatonin supplements had significantly lower serum insulin levels (β -2.53; 95% CI, -4.48, -0.59; P = 0.01), homeostasis model of assessment-insulin resistance (β -0.56; 95% CI, -1.03, -0.09; P = 0.01) and higher quantitative insulin sensitivity check index (β 0.01; 95% CI, 0.004, 0.02; P = 0.009) and HDL-cholesterol levels (β 3.71; 95% CI, 1.77, 5.64; P = 0.002) compared to placebo. Additionally, melatonin intake resulted in a significant reduction in serum high sensitivity C-reactive protein (β -0.15; 95% CI, -0.27, -0.02; P = 0.02), malondialdehyde (β -0.31; 95% CI, -0.57, -0.05; P = 0.02) and protein carbonyl (β -0.06; 95% CI, -0.09, -0.04; P < 0.001). This trial indicated that taking melatonin supplements for 12 weeks by patients under MMT had beneficial effects on their mental health metabolic profiles.

Melatonin and health: an umbrella review of health outcomes and biological mechanisms of action. BMC Med 2018; 16:18. [PMID: 29397794 PMCID: PMC5798185 DOI: 10.1186/s12916-017-1000-8] [Citation(s) in RCA: 52] [Impact Index Per Article: 8.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/16/2017] [Accepted: 12/20/2017] [Indexed: 12/21/2022] Open
Abstract
BACKGROUND Our aims were to evaluate critically the evidence from systematic reviews as well as narrative reviews of the effects of melatonin (MLT) on health and to identify the potential mechanisms of action involved. METHODS An umbrella review of the evidence across systematic reviews and narrative reviews of endogenous and exogenous (supplementation) MLT was undertaken. The Oxman checklist for assessing the methodological quality of the included systematic reviews was utilised. The following databases were searched: MEDLINE, EMBASE, Web of Science, CENTRAL, PsycINFO and CINAHL. In addition, reference lists were screened. We included reviews of the effects of MLT on any type of health-related outcome measure. RESULTS Altogether, 195 reviews met the inclusion criteria. Most were of low methodological quality (mean -4.5, standard deviation 6.7). Of those, 164 did not pool the data and were synthesised narratively (qualitatively) whereas the remaining 31 used meta-analytic techniques and were synthesised quantitatively. Seven meta-analyses were significant with P values less than 0.001 under the random-effects model. These pertained to sleep latency, pre-operative anxiety, prevention of agitation and risk of breast cancer. CONCLUSIONS There is an abundance of reviews evaluating the effects of exogenous and endogenous MLT on health. In general, MLT has been shown to be associated with a wide variety of health outcomes in clinically and methodologically heterogeneous populations. Many reviews stressed the need for more high-quality randomised clinical trials to reduce the existing uncertainties.

Abstract
SummaryChildren and adolescents with intellectual disability have high rates of psychiatric morbidity, the most common presentation being behavioural difficulties, especially in the context of autism. This clinical review describes the applicability of the full range of current psychopharmacological agents to the mental health difficulties commonly encountered in clinical practice in this field, with an emphasis on informing the choice of an initial ‘best fit’ single agent for the various clusters of symptoms and signs presented by individual patients. It is emphasised that the evidence base for most practice parameters in this area is extremely modest and that a high level of caution is recommended when applying this information in everyday practice. The article also discusses some of the specific difficulties and challenges encountered within the field and makes some practical suggestions for good practice.

Abstract
BACKGROUND Behavioural interventions are frequently used to address sleep problems in people with intellectual disabilities (ID). The current study aimed to systematically review evidence on the efficacy of behavioural interventions for children and adults with ID and sleep problems. METHOD Electronic and hand searches identified seven studies for inclusion (N = 169). Standardised mean difference effect sizes (d) were calculated for group studies (N = 4). Non-overlap effect sizes (Tau-U) were calculated for single case experimental design studies (SCEDs; N = 3). RESULTS A large effect size (weighted d = 0.923, confidence interval: 0.705 to 1.151) across group studies indicated large improvements in sleep problems following behavioural intervention. Effect size across SCEDs (weighted Tau-U: 0.528, confidence interval: 0.351 to 0.705) indicated a 53% improvement compared with baseline. Sleep initiation and sleep maintenance problems showed significant improvements post-intervention. Follow-up effects were less consistent across study designs and suggested that some sleep problems maintain gains better than others. CONCLUSION Meta-analytic evidence from group and SCEDs can provide complementary information about efficacy. Findings propose that behavioural interventions are a promising evidence-based practice for improving sleep problems in people with ID.

Abstract
Abstract
Developmental disorders in children are common. Associated demanding co-morbidities that include sleep problems are prevalent in this group. In turn, these are linked to daytime performance issues, reduced developmental and academic growth, and considerable familial psychopathology. Behavioral modification measures are and should be the first line approach to management. Medications for sleep disorders have an important role in addition to behavioral modification therapy. This literature review looks into the occurrence and severity of sleep problems in children with developmental disorders. The probable advantages of using medications, mainly focusing on the neurohormone melatonin (a sleep inducer), are also explored.

Abstract
This article reviews circadian rhythm sleep disorders (CRSDs) of children with neurodevelopmental disabilities. These sleep disturbances frequently occur in this population but they are misunderstood and under diagnosed. The causes and features of CRSD in children with brain disorders differ in many ways from those seen in typically developing children. It is the brain, including the eyes, which regulates sleep and circadian rhythmicity by modulating pineal melatonin production/secretion and when there is significant brain damage, the sleep/wake patterns may be modified. In most instances CRSD are not disorders of the suprachiasmatic nuclei because these small hypothalamic structures only adjust their functions to the changing photic and non-photic modulatory influences. Each form of CRSD is accompanied by characteristic changes in serum melatonin levels and clinical features. When nocturnal melatonin production/secretion is inappropriately timed or impaired in relation to the environment, timed melatonin replacement therapy will often be beneficial. In this review an attempt is made to clarify the neurophysiological mechanisms underlying the various forms of CRSD because without understanding the photic and non-photic influences on sleep, these sleep disorders can not be fully characterized, defined or even appropriately treated. In the future, the existing definitions for the different forms of CRSD should be modified by experts in pediatric sleep medicine in order to include children with neurodevelopmental disabilities.

Abstract
PURPOSE OF REVIEW Advances in developmental neuropsychiatry and the mental health needs of people with intellectual disability are creating ever greater understanding of the critical associations between human genome variations and psychological functioning throughout lifespan and across the entire intellectual ability spectrum. This review highlights the recent developments and their clinical implications for people with fragile X syndrome. RECENT FINDINGS There is substantial evidence for individuals of all ages and intellectual abilities being prone to psychological profiles determined not only by having a fragile X gene full mutation, but also by having premutations and intermediate alleles. The importance of these genetic contributors to mental life, if anything, increases with age. Premutation carriers are prone to neurodegenerative mid-life fragile X tremor-ataxia syndrome. Women with premutations experience premature ovarian insufficiency. Imbalances in the (gamma amino butyrie acid)-glutamate mediated postsynaptic cascade central neuronal pathways are a current focus of psychopharmacological enquiry, giving the hope of syndrome-specific medical treatments. SUMMARY Findings from genetic, neurological, biochemical, psychological and pharmacological research are combining to revolutionize understanding of the pathogenesis of developmental and psychological disabilities affecting individuals with fragile X syndrome irrespective of age, intelligence level and gene mutation status. Results of syndrome-specific medication trials are awaited.

Abstract
STUDY OBJECTIVES This study reports on current child sleep difficulties reported by parents of children with Fragile X syndrome (FXS). We address prevalence and type of sleep problems (e.g., difficulty falling asleep, frequent awakenings); type and effectiveness of medical and behavioral treatments (e.g., medication, surgery, environmental changes); and explore specific child and family characteristics (e.g., child age, child gender, co-occurring conditions) as possible predictors of child sleep difficulties. DESIGN/PARTICIPANTS This study is part of a larger survey addressing needs of families with children with FXS. This article focuses on the families who responded to the survey sleep questions, had one or more children with the full mutation FXS, and who reside in the United States. The mean age for male and female children in this group was 15 years and 16 years respectively (N=1295). RESULTS Parents reported that 32% of the children with FXS currently experience sleep difficulties; 84% of those children are reported to have > or =2 current sleep problems. Problems falling asleep and frequent night awakenings were the most frequently reported difficulties; 47% of males and 40% of females received > or =1 medication to help with sleep. Children with more problematic health or behavioral characteristics had a higher likelihood of having current sleep problems. CONCLUSIONS Our survey provides the most representative sample to date of sleep problems in children with FXS or any other neurodevelopmental disability. This large scale survey establishes a foundation for the prevalence of sleep disorders in children with FXS.

Caregivers reported on sleep in a convenience sample of 90 children with fragile X syndrome utilizing a standardized assessment tool, the Children's Sleep Habits Questionnaire (CSHQ), and a 14-day sleep diary. CSHQ data indicated that 47% of participants had sleep problems at a level that suggested referral and further evaluation. Sleep diary data indicated high rates of several sleep problems. These problems did not appear to follow a typical developmental trajectory and were not related to gender or demographic variables. Nineteen percent of the sample was currently receiving medication to improve sleep; however, there were no significant differences between those receiving medications and those not receiving medications.

Abstract
Recent meta-analyses on melatonin has raised doubts as to whether melatonin is effective in treating sleep problems in people without intellectual disabilities. This is in contrast to results of several trials on melatonin in treating sleep problems in individuals with intellectual disabilities. To investigate the efficacy of melatonin in treating sleep problems in individuals with intellectual disabilities, we performed a meta-analysis of placebo-controlled randomized trials of melatonin in individuals with intellectual disabilities and sleep problems. Data were selected from articles published on PubMed, Medline, and Embase between January 1990 and July 2008. We examined the influence of melatonin on sleep latency, total sleep time, and number of wakes per night. Quality of trials was assessed using the Downs and Black checklist. Nine studies (including a total of 183 individuals with intellectual disabilities) showed that melatonin treatment decreased sleep latency by a mean of 34 minutes (p<0.001), increased total sleep time by a mean of 50 minutes (p<0.001), and significantly decreased the number of wakes per night (p<0.05). Melatonin decreases sleep latency and number of wakes per night, and increases total sleep time in individuals with intellectual disabilities.

Abstract
Fragile X syndrome is the world's most common hereditary cause of intellectual disability in men and to a lesser extent in women. The disorder is caused by the silencing of a single gene on the X chromosome, the Fragile X Mental Retardation Gene-1. A substantial body of research across the disciplines of molecular genetics, child psychiatry and developmental neuroscience bears testament to a decade of exciting and innovative science that has advanced our knowledge about the fragile X 'signature' or influence across cognitive and social development. The core aims of this review are to first discuss fragile X syndrome and premutation involvement in the context of current advances that demonstrate the dynamic nature of the genotype on phenotypic outcomes. Second, to discuss the implications of these recent advances for the development of clinical and educational interventions and resource tools that target specific phenotypic 'signatures' within the fragile X continuum.

Abstract
BACKGROUND There is a paucity of research on professionals' and parents' views on melatonin use in children and adolescents with sleep problems. METHOD A two-stage survey was employed. First stage: Child psychiatrists and community paediatricians working in a health district were surveyed. Second stage: Parents/carers of children currently on melatonin under the care of these clinicians completed questionnaires. RESULTS Eighty-seven per cent of the participating clinicians prescribed melatonin, with most of them prescribing melatonin for chronic and treatment resistant cases. Differences in prescribing practices between child psychiatrists and community paediatricians were noted. All children were prescribed either 3 mgs or 6 mgs melatonin. None of them experienced any significant side effects. CONCLUSIONS This research highlights that clinicians recognise melatonin as an effective treatment of childhood insomnia and parents value its usefulness too.

Abstract
The purpose of this study was to determine the efficacy of controlled-release (CR) melatonin in the treatment of delayed sleep phase syndrome and impaired sleep maintenance of children with neurodevelopmental disabilities including autistic spectrum disorders. A randomized double-blind, placebo-controlled crossover trial of CR melatonin (5 mg) followed by a 3-month open-label study was conducted during which the dose was gradually increased until the therapy showed optimal beneficial effects. Sleep characteristics were measured by caregiver who completed somnologs and wrist actigraphs. Clinician rating of severity of the sleep disorder and improvement from baseline, along with caregiver ratings of global functioning and family stress were also obtained. Fifty-one children (age range 2-18 years) who did not respond to sleep hygiene intervention were enrolled. Fifty patients completed the crossover trial and 47 completed the open-label phase. Recordings of total night-time sleep and sleep latency showed significant improvement of approximately 30 min. Similarly, significant improvement was observed in clinician and parent ratings. There was additional improvement in the open-label somnolog measures of sleep efficiency and the longest sleep episode in the open-label phase. Overall, the therapy improved the sleep of 47 children and was effective in reducing family stress. Children with neurodevelopmental disabilities, who had treatment resistant chronic delayed sleep phase syndrome and impaired sleep maintenance, showed improvement in melatonin therapy.

Abstract
To date, there have been no prospective long-term studies of melatonin therapy in children. We report here data from a prospective follow-up study of 44 children with neurodevelopmental disabilities and treatment-resistant circadian rhythm sleep disorders (CRSD) who had participated in a placebo controlled, double blind cross-over trial of sustained-release melatonin. The follow-up study involved a structured telephone interview of caregivers every 3 months for upto 3.8 yr. The caregivers provided ratings of satisfaction, adverse effects, benefits, persistence with treatment and additional medications. Changes in melatonin dose were recorded. Open ended questions were included to capture caregivers' impressions and comments concerning melatonin therapy. Adverse reaction to melatonin therapy and development of tolerance were not evident. Better sleep was associated with reported improvement in health, behavior and learning. At the end of the study, the parental comments regarding the effectiveness of long-term melatonin therapy were highly positive. Parents whose children had sleep maintenance difficulties expressed a wish to have a commercially available controlled-release melatonin product which would promote sleep for 8-10 hr. Hypnotics for children with CRSD should be considered a second line of treatment for those who fail to respond to sleep hygiene and/or melatonin.

Abstract
Pediatricians have an important role not only in early recognition and evaluation of autism spectrum disorders but also in chronic management of these disorders. The primary goals of treatment are to maximize the child's ultimate functional independence and quality of life by minimizing the core autism spectrum disorder features, facilitating development and learning, promoting socialization, reducing maladaptive behaviors, and educating and supporting families. To assist pediatricians in educating families and guiding them toward empirically supported interventions for their children, this report reviews the educational strategies and associated therapies that are the primary treatments for children with autism spectrum disorders. Optimization of health care is likely to have a positive effect on habilitative progress, functional outcome, and quality of life; therefore, important issues, such as management of associated medical problems, pharmacologic and nonpharmacologic intervention for challenging behaviors or coexisting mental health conditions, and use of complementary and alternative medical treatments, are also addressed.

Abstract
The use of pharmacologic agents as a component of treatment for children and adults with autism spectrum disorders is common and a substantial body of literature describing controlled and open-label clinical trials now exists to guide clinical practice. Empiric evidence of efficacy of risperidone, methylphenidate and some selective serotonin re-uptake inhibitors for maladaptive behaviors commonly associated with autism spectrum disorders has increased substantially in recent years. Preliminary controlled trials of valproate, atomoxetine, alpha-2 adrenergic agonists and olanzapine are promising. In addition to traditional psychotropic medications, investigators have examined the potential role of a variety of agents with glutamatergic or cholinergic mechanisms, and the results warrant further investigation. Although psychotropic medications are effective in treating some important associated behaviors, evidence of significant impact on the core features of autism spectrum disorders is very limited.

Laakso ML, Lindblom N, Leinonen L, Kaski M. Endogenous melatonin predicts efficacy of exogenous melatonin in consolidation of fragmented wrist-activity rhythm of adult patients with developmental brain disorders: A double-blind, placebo-controlled, crossover study. Sleep Med 2007; 8:222-39. [PMID: 17368097 DOI: 10.1016/j.sleep.2006.09.006] [Citation(s) in RCA: 12] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/06/2006] [Revised: 08/11/2006] [Accepted: 09/03/2006] [Indexed: 10/23/2022]
Abstract
OBJECTIVE : We studied whether the endogenous melatonin patterns in adult patients with developmental brain disorders have any role in response to exogenous melatonin given as a sleep-promoting medicine. METHODS : Participants included 15 adults (18-60 years, five females) with developmental brain disorders of varying etiologies, motor handicaps, and long-term history of sleep problems. According to the 24-h patterns of serum melatonin, patients were divided into two subgroups: lower and higher secretors. The pretreatment sleep disorder was characterized by a structured interview, 24-h ambulatory polysomnography and 7-day wrist actigraphy. Patients received 1, 3, or 6mg fast-release melatonin tablets, each for 4 weeks in increasing order, at a constant time of 30min before the desired sleep onset. Similarly, placebos with different codes were given during 3x4 weeks. The 7-day actigraphy was repeated at the end of each drug period. Outcome measures were six different parameters of non-parametric circadian rhythm analysis. Drug effects and 40 confounding/modulating factors were evaluated by applying two-level regression analyses with co-variables. RESULTS : Exogenous melatonin decreased the fragmentation of the rest-activity rhythm, increased the day/night ratio of activity and advanced the onset of rest period. The effects on fragmentation and day/night ratio were more pronounced in the lower than higher secretors of melatonin. Other contributing factors in the drug effects were blindness and some features of the original sleep disorder (disrupted cyclicity of the sleep architecture in polysomnography or reported daytime somnolence). CONCLUSIONS : Exogenous melatonin consolidated the fragmented rest-activity in about half of the patients. Low endogenous serum melatonin levels at night predicted improvement by the drug. Higher doses were not more effective than the lowest dose.

Abstract
There are strong associations between childhood sleep disorders and behavioural, concentration and mood problems. Sleep disorders caused and maintained by behavioural factors (eg, sleep-onset association disorder) are common in young children, and have a significant impact on families. Evaluation should include a medical history, a physical, neurological and developmental examination, a description of any nocturnal events or daytime effects of the child's disturbed sleep, and a good understanding of the family situation and parental management of the child. Management involves recognising the developmental age of the child and the family dynamics, and educating and supporting families in applying behavioural techniques to establish good sleep hygiene. Children with parasomnias (eg, night terrors) also benefit from good sleep hygiene, while those with respiratory or neurological causes of sleep disturbance should be referred for specialist treatment.

Abstract
This paper reports on the use of clonidine for the treatment of severe sleep problems associated with behavioural difficulties in children with neurodevelopmental disabilities. Data were obtained from reviewing the case notes of a series of six children with neurodevelopmental disorders of different nature and severity, presenting with problematic sleep. All children in this group showed maintained improvements in their sleep pattern following the use of clonidine with only mild side-effects reported.
