Abstract
BACKGROUND Attention-deficit hyperactivity disorder (ADHD) is associated with disrupted sleep and circadian rhythm. Medication for ADHD may have side effects aggravating sleep-disturbances, however beneficial effects on ADHD may contribute to improve sleep. AIMS This pilot study aims to examine outcomes of first time stimulant treatment on objective and subjective sleep characteristics, and psychiatric symptoms, in adult ADHD patients with pretreatment sleep problems, but without any primary sleep disorder. METHODS In total, 9 previously unmedicated adult ADHD subjects who reported pretreatment sleep problems, completed polysomnography (PSG) and questionnaires on subjective sleep disturbances and psychiatric symptoms. Data was collected before and after 6 weeks on first time medication with immediate-release methylphenidate (MPH-IR), mean daily dose 43 mg. RESULTS Subjects on-medication showed an increased percentage of Stage 2 sleep compared to their non-treated baseline (46.6% versus 55.2%, p = .011). Otherwise, there were no significant changes in PSG variables. There were no firm changes in daytime sleepiness or symptoms of sleep disturbances. CONCLUSIONS These findings should be interpreted cautiously given the open-label design and small sample size, and should be examined in larger studies with more rigorous study designs.

Abstract
OBJECTIVE High incidence of sleep problems in children and adolescents with Attention-Deficit/Hyperactivity Disorder (ADHD) has been described. Mindfulness meditation has emerged as a novel approach to sleep disturbances and insomnia remediation. This preliminary study tested the efficacy of Mindfulness-Oriented Meditation (MOM) training on sleep quality and behavioral problems in children with ADHD. DESIGN Twenty-five children with ADHD aged 7-11 years underwent two programs three times per week for eight-weeks: the MOM training (15 children) and an Active Control Condition (10 children). MAIN OUTCOME MEASURES Objective and subjective measures of sleep quality and behavioral measures were collected before and after the programs. RESULTS Positive effects on sleep and behavioral measures were found only in the MOM group. CONCLUSION Although they are preliminary, our results indicate that MOM training is a promising tool for ameliorating sleep quality and behavioral manifestations in ADHD.

Abstract
Attention deficit hyperactivity disorder (ADHD) is a neurodevelopmental disorder in which patients present inattention, hyperactivity, and impulsivity. The etiology of this condition is diverse, including environmental factors and the presence of variants of some genes. However, a great diversity exists among patients regarding the presence of these ADHD-associated factors. Moreover, there are variations in the reported neurophysiological correlates of ADHD. ADHD is often treated pharmacologically, producing an improvement in symptomatology, albeit there are patients who are refractory to the main pharmacological treatments or present side effects to these drugs, highlighting the importance of developing other therapeutic options. Different non-pharmacological treatments are in this review addressed, finding diverse results regarding efficacy. Altogether, ADHD is associated with different etiologies, all of them producing changes in brain development, leading to the characteristic symptomatology of this condition. Given the heterogeneous etiology of ADHD, discussion is presented about the convenience of personalizing ADHD treatment, whether pharmacological or non-pharmacological, to reach an optimum effect in the majority of patients. Approaches to personalizing both pharmacological therapy and neurofeedback are presented.

Abstract
College students show high levels of insufficient sleep, excessive daytime sleepiness, sleep schedule irregularity, poor sleep quality, and inadequate sleep hygiene. This article describes the evidence linking poor sleep with impaired academic performance; discusses mediating environmental, behavioral, and demographic factors that correlate with sleep; and highlights examples of successful health promotion initiatives on college campuses. Given that students who are traditionally minoritized on college campuses tend to have worse sleep, improving sleep health emerges as an important issue for retention, equity, and inclusion.

High occurrence of sleep problems in survivors of a childhood brain tumor with neurocognitive complaints: The association with psychosocial and behavioral executive functioning. Pediatr Blood Cancer 2019; 66:e27947.

Abstract
BACKGROUND Survivors of childhood brain tumors are prone to sleep and neurocognitive problems. Effective interventions to improve neurocognitive functioning are largely lacking. In general, sleep problems are negatively related to neurocognitive functioning, but this relationship is unclear in survivors of childhood brain tumors. Therefore, the occurrence of sleep problems, potential risk factors, and the relation between sleep and executive functioning were evaluated. PROCEDURE Baseline data of a randomized controlled trial on the effectiveness of neurofeedback were used. Childhood brain tumor survivors 8-18 years of age with parent-reported neurocognitive complaints ≥2 years after treatment were eligible. Parents completed the Sleep Disturbance Scale for Children. Executive functioning was assessed by parents and teachers (Behavior Rating Inventory of Executive Functioning). Multiple linear regression analyses were used to examine sociodemographic and medical characteristics and emotional difficulties and hyperactivity/inattention (Strength and Difficulties Questionnaire) as potential risk factors for sleep problems, and to assess the association between sleep and executive functioning. RESULTS Forty-eight percent of survivors (n = 82, 7.0 ± 3.6 years post diagnosis, age 13.8 ± 3.2 years) had sleep problems and scored significantly worse than the norm on the subscales Initiating and Maintaining Sleep, Excessive Somnolence, and the total scale (effect sizes 0.58-0.92). Emotional problems and/or hyperactivity/inattention were independent potential risk factors. Sleep problems were associated with worse parent-reported executive functioning. CONCLUSIONS Sleep problems occur among half of childhood brain tumor survivors with neurocognitive problems, and are associated with worse executive functioning. Future studies should focus on the development of sleep interventions for this population, to improve sleep as well as executive functioning.

Abstract
Sleep problems are common in autism spectrum disorder (ASD) and attention deficit hyperactivity disorder (ADHD). Sleep problems in these disorders may not only worsen daytime behaviors and core symptoms of ASD and ADHD but also contribute to parental stress levels. Therefore, the presence of sleep problems in ASD and ADHD requires prompt attention and management. This article is presented in 2 sections, one each for ASD and ADHD. First, a detailed literature review about the burden and prevalence of different types of sleep disorders is presented, followed by the pathophysiology and etiology of the sleep problems and evaluation and management of sleep disorders in ASD and ADHD.

Abstract
OBJECTIVES We tested the hypothesis that sleep training would improve emotional, social and behavioural functioning in children with attention-deficit/hyperactivity disorder (ADHD) compared to children with ADHD without such intervention and to healthy controls. METHODS Forty children with ADHD were randomly assigned to intervention and control conditions. Parents of 20 children with ADHD were instructed and thoroughly supervised in improving their children's sleep schedules and sleep behaviour. Parents of the other 20 children with ADHD and parents of 20 healthy children received general information about sleep hygiene. At baseline and 12 weeks later, parents and children completed questionnaires related to children's sleep and psychological functioning. RESULTS Relative to the control groups, children in the intervention group improved sleep quantitatively and qualitatively (F values < 3.33, P values < 0.05). The intervention group children reported improvements in mood, emotions, and relationships (F values < 2.99, P values < 0.05). Parents reported that their children improved in physical and psychological wellbeing, mood, emotions, relationships, and social acceptance (F values < 3.02, P values < 0.05). CONCLUSIONS Training and monitoring parents of children with ADHD in regulating and supervising children's sleep schedules leads to positive changes in the emotions, behaviour and social lives of these children.

Abstract
OBJECTIVE Current recommendations for evaluation and diagnosis of attention-deficit hyperactivity disorder (ADHD) are meant for primary care settings and may not adequately address the needs of children seen in subspecialty developmental-behavioral pediatric settings who may have higher rates of comorbid developmental, learning, and psychiatric disorders. The authors sought to characterize the diagnostic complexity of school-aged children diagnosed with ADHD after comprehensive multidisciplinary evaluation in a subspecialty developmental-behavioral pediatric clinic. METHODS The authors conducted a retrospective medical record review of 144 patients aged 7 to 11 years who were consecutively evaluated by an interdisciplinary team (developmental-behavioral pediatrician, psychologist, educator) in a school-age clinic within a developmental-behavioral pediatrics tertiary care center from January 1, 2009 to December 31, 2009. RESULTS After comprehensive evaluation, rates of ADHD diagnosis increased from 32.6% (n = 47) preevaluation to 54.2% (n = 78) postevaluation (p < .0001). Rates of learning disorders among children receiving a final diagnosis of ADHD increased from 2.6% (n = 2) preevaluation to 50% (n = 39) postevaluation. (p < .0001). Among children receiving a final diagnosis of ADHD, 73.1% (n = 57) were diagnosed with at least 1 comorbid psychiatric, developmental, or learning disorder. CONCLUSIONS Among school-aged children diagnosed with ADHD in a developmental-behavioral pediatric subspecialty setting, a comprehensive evaluation including developmental, neuropsychological, and educational assessments yielded high rates of comorbid psychiatric, developmental, and learning disorders. This supports the need to provide comprehensive interdisciplinary assessment for such children to ensure the identification and treatment of not only the core symptoms of ADHD but also the comorbidities that may otherwise go unrecognized and therefore not optimally treated.

Abstract
Attention-deficit/hyperactivity disorder (ADHD) is commonly associated with disordered or disturbed sleep. The relationships of ADHD with sleep problems, psychiatric comorbidities and medications are complex and multidirectional. Evidence from published studies comparing sleep in individuals with ADHD with typically developing controls is most concordant for associations of ADHD with: hypopnea/apnea and peripheral limb movements in sleep or nocturnal motricity in polysomnographic studies; increased sleep onset latency and shorter sleep time in actigraphic studies; and bedtime resistance, difficulty with morning awakenings, sleep onset difficulties, sleep-disordered breathing, night awakenings and daytime sleepiness in subjective studies. ADHD is also frequently coincident with sleep disorders (obstructive sleep apnea, peripheral limb movement disorder, restless legs syndrome and circadian-rhythm sleep disorders). Psychostimulant medications are associated with disrupted or disturbed sleep, but also ‘paradoxically’ calm some patients with ADHD for sleep by alleviating their symptoms. Long-acting formulations may have insufficient duration of action, leading to symptom rebound at bedtime. Current guidelines recommend assessment of sleep disturbance during evaluation of ADHD, and before initiation of pharmacotherapy, with healthy sleep practices the first-line option for addressing sleep problems. This review aims to provide a comprehensive overview of the relationships between ADHD and sleep, and presents a conceptual model of the modes of interaction: ADHD may cause sleep problems as an intrinsic feature of the disorder; sleep problems may cause or mimic ADHD; ADHD and sleep problems may interact, with reciprocal causation and possible involvement of comorbidity; and ADHD and sleep problems may share a common underlying neurological etiology.

Abstract
Sleep problems are common in attention-deficit/hyperactivity disorder (ADHD) to the extent that they mimic or exacerbate daytime symptoms expression. In this review, we advocate the need for a better understanding of sleep alterations in youths with ADHD and their impact on neurobehavioral functions including learning, memory and emotional regulation. An in-depth exploration of existing data showed that although extensively studied, the actual nature of sleep problems in ADHD and their effects on daytime behavior are still less well understood. Important issues, among which developmental changes in sleep architecture and role of subtle sleep electroencephalogram signatures, are generally neglected. Future research of sleep effects on behavior in ADHD would benefit from considering developmental aspects and links between brain activation patterns during sleep and wake.

Abstract
OBJECTIVES Attention-deficit hyperactivity disorder (ADHD) is characterized by inattentive and impulsive behavior. Many ADHD patients reportedly have cognitive dysfunction and sleep problems, including longer sleep latency, lower sleep efficiency, and shorter total sleep time. The purpose of this study was to examine neurocognitive functions and nocturnal sleep parameters in patients with ADHD, using a cognitive function test and actigraphy. METHODS Subjects included 37 male patients with ADHD and 32 controls (7-12 years of age). For each participant, we determined intelligence quotient (IQ) and administered the Matching Familiar Figures Test (MFFT) and 72-hour actigraphy. The relationships between sleep parameters and cognitive functions were assessed. RESULTS ADHD patients significantly differed from controls in several cognitive functions and sleep variables. In the MFFT, response error rate (P<0.001) and error counts (P=0.003) were significantly increased in ADHD patients compared with control children. MFFT response latency was significantly shorter in ADHD patients than in controls (P<0.001). In addition, sleep latency (P=0.01), wake after sleep onset (WASO) (P<0.001), and fragmentation index (P<0.001) were evaluated by actigraphy and found to be significantly increased in patients with ADHD compared with controls. However, no significant differences in total sleep time or sleep efficiency were observed. WASO and response error rates were positively correlated in patients with ADHD (rho =0.52, P=0.012). Furthermore, fragmentation index sleep variables were significantly positively correlated with response error (rho =0.44, P=0.008) and response latency rates (rho =0.4, P=0.018) in the MFFT. Reaction error rate was significantly associated with the fragmentation index (beta =0.94, P=0.024). CONCLUSION Patients with ADHD had more sleep problems, including significantly increased sleep latency, WASO, and fragmentation index, and poorer cognitive function, compared with controls. Some of these sleep problems, including WASO and the fragmentation index, were positively correlated with impulsivity, illustrated by the cognitive function tests in patients with ADHD. However, further studies with large sample sizes and the addition of polysomnography and determination of ADHD subtypes should be performed to confirm our results regarding sleep and cognitive problems in patients with ADHD.

Abstract
OBJECTIVE This systematic review assessed current evidence on sleep medication for attention-deficit/hyperactivity disorder (ADHD) patients, to establish appropriate guidance for clinicians faced with prescribing such medications. METHODS Five articles (based on four pharmacological compounds) out of a total 337 were identified as evidence to guide pharmacological treatment of ADHD-related sleep disorders. Data regarding participant characteristics, measures of ADHD diagnosis, measures of sleep, and outcome data were extracted. RESULTS Zolpidem and L-theanine both displayed a poor response in reducing sleep latency and increasing total sleep time, however L-theanine did produce an increase in sleep efficiency. Zolpidem produced high levels of side effects, leading to the largest dropout rate of all five studies. Clonidine reduced insomnia; and melatonin also exhibited a positive response, with reduced sleep latency, higher total sleep time, and higher sleep efficiency. CONCLUSIONS There is a relative paucity of evidence for the pharmacological treatment of ADHD-related sleep disorders; therefore, further research should be conducted to replicate these findings and obtain reliable results.

Abstract
Sleep and wake are actively promoted states of consciousness that are dependent on a network of state-modulating neurons arising from both the brain stem and hypothalamus. This network helps to coordinate the occurrence of a sleep state in billions of cortical neurons. In many neurological diseases, there is a specific disruption to one of the components of this network. Under conditions of such disruptions, we often gain an improved understanding of the underlying function of the specific component under nonpathological conditions. The loss or dysfunction of one of the hypothalamic or brain stem regions that are responsible for promotion of sleep or wake can lead to disruptions in sleep and wake states that are often subtle, but sometime quite pronounced and of significant medical importance. By understanding the neural substrate and its pathophysiology, one can more appropriately target therapies that might help the specific sleep disruption. This chapter reviews what is currently understood about the neurobiological underpinnings of sleep and wake regulation and how various pathologies evoke changes in these regulatory mechanisms.

Abstract
Sleep problems are a prominent feature in children with attention-deficit/hyperactivity disorder (ADHD) but their relationships to sleep structure are not consistent across studies. We aimed at further examining the sleep architecture in children with ADHD, while considering the role of the first-night effect (FNE) as a possible confounder. Twenty unmedicated children with ADHD combined type (8-15 years old; mean 11.24, SD 2.31) and 19 healthy controls, matched for age and gender, underwent polysomnography during an adaptation and a consecutive second night. ADHD and controls displayed a typical FNE without group differences. Independently of testing night, children with ADHD spent more time in sleep and had shortened rapid eye movement (REM) sleep latency and a greater amount of REM sleep relative to controls. However, the increased REM sleep amount in ADHD children was more expressed in the second night when it was also significantly related to scores of inattention and hyperactivity. Our results (1) document similar sleep adaptation processes in children with ADHD and typically developing children, (2) reveal that REM sleep changes in association with ADHD-specific psychopathology may characterize sleep in ADHD children, which is evident only when the FNE is accounted for, (3) indicate that ADHD psychopathology and adaptation night may exert opposite effects on REM sleep in children. These results may prompt the awareness of clinicians about the importance of actual sleep alterations and their precise evaluation in children with ADHD, which could significantly contribute to better diagnostic, treatment and early prevention strategies.

Abstract
ADHD, sleep, and ADHD treatments are highly interrelated. In this review, we describe the effects of stimulants and non stimulant medications on sleep in children, adolescents, and adults with ADHD. Clinical predictors of sleep problems during pharmacotherapy include age, sleep problems prior to initiating treatment, and dose and dosing schedule. As yet, we have little understanding of the biological or genetic factors related to individual variation in drug response and sleep.

Ashkenasi A. Effect of transdermal methylphenidate wear times on sleep in children with attention deficit hyperactivity disorder. Pediatr Neurol 2011; 45:381-6. [PMID: 22115000 DOI: 10.1016/j.pediatrneurol.2011.09.003] [Citation(s) in RCA: 9] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/01/2011] [Accepted: 09/02/2011] [Indexed: 10/15/2022]
Abstract
Sleep disturbances are common among children and adolescents with attention deficit hyperactivity disorder. This study sought to evaluate the effects of individualizing wear times of the methylphenidate transdermal system on sleep parameters. In this open-label, randomized trial, 26 children with attention deficit hyperactivity disorder and sleep disturbances were randomized (after dose optimization) to one of four groups with different sequences of patch wear times (i.e., 9, 10, 11, and 12 hours per day wear times each for week in different sequences). The primary endpoint comprised sleep latency. Secondary endpoints included total sleep time, sleep quality, and attention deficit hyperactivity disorder and related signs (assessed with Attention Deficit Hyperactivity Disorder Rating Scale-IV and Connor's Global Impression-Parent). A mixed-effects regression model evaluated the effects of patch wear time on sleep and symptom measures. Patch wear time exerted no significant effect on sleep latency or total sleep time, although a trend toward improved sleep quality was evident (P = 0.059) with longer patch wear times. Sleep parameters were not adversely affected by longer methylphenidate transdermal system patch wear times. Thus, if replicated in larger samples, the individualization of patch wear times should be considered according to the needs and responses of patients.

Comparison of sleep problems in children with anxiety and attention deficit/hyperactivity disorders. Eur Child Adolesc Psychiatry 2011; 20:321-30. [PMID: 21533911 DOI: 10.1007/s00787-011-0179-z] [Citation(s) in RCA: 40] [Impact Index Per Article: 3.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/14/2010] [Accepted: 04/13/2011] [Indexed: 10/18/2022]
Abstract
This cross-sectional case-control study compared sleep problems in consecutively referred children aged 7-13 years meeting DSM-IV criteria for anxiety disorder, attention deficit/hyperactivity disorder (ADHD), comorbid anxiety disorder and ADHD, and a group of control children of similar age and gender. Diagnoses were assessed with the Kiddie-SADS PL interview, parent form, and the sleep problems with a standardized sleep questionnaire, the Children's Sleep Habits Questionnaire (CSHQ), as reported by the mother. A total of 141 children were included (anxiety disorder (n = 41), ADHD (n = 39), comorbid condition (n = 25), controls (n = 36)). Children in the clinical groups had more sleep problems than controls. Children with anxiety disorders and children with comorbid condition were reported to have more sleep problems than children with ADHD alone. Night waking was associated with comorbid anxiety disorder and ADHD. Bedtime resistance was associated with anxiety disorder, while daytime sleepiness affected all clinical groups. Clinical management of children with ADHD and anxiety disorders needs to include assessment of sleep problems.

[PMID: 21537851 DOI: 10.1007/s10916-011-9710-5] [Citation(s) in RCA: 168] [Impact Index Per Article: 12.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/07/2011] [Accepted: 04/07/2011] [Indexed: 10/18/2022]
Abstract
As a new concept that emerged in the middle of 1990's, data mining can help researchers gain both novel and deep insights and can facilitate unprecedented understanding of large biomedical datasets. Data mining can uncover new biomedical and healthcare knowledge for clinical and administrative decision making as well as generate scientific hypotheses from large experimental data, clinical databases, and/or biomedical literature. This review first introduces data mining in general (e.g., the background, definition, and process of data mining), discusses the major differences between statistics and data mining and then speaks to the uniqueness of data mining in the biomedical and healthcare fields. A brief summarization of various data mining algorithms used for classification, clustering, and association as well as their respective advantages and drawbacks is also presented. Suggested guidelines on how to use data mining algorithms in each area of classification, clustering, and association are offered along with three examples of how data mining has been used in the healthcare industry. Given the successful application of data mining by health related organizations that has helped to predict health insurance fraud and under-diagnosed patients, and identify and classify at-risk people in terms of health with the goal of reducing healthcare cost, we introduce how data mining technologies (in each area of classification, clustering, and association) have been used for a multitude of purposes, including research in the biomedical and healthcare fields. A discussion of the technologies available to enable the prediction of healthcare costs (including length of hospital stay), disease diagnosis and prognosis, and the discovery of hidden biomedical and healthcare patterns from related databases is offered along with a discussion of the use of data mining to discover such relationships as those between health conditions and a disease, relationships among diseases, and relationships among drugs. The article concludes with a discussion of the problems that hamper the clinical use of data mining by health professionals.

Fatigue, vitality, sleep, and neurocognitive functioning in adult survivors of childhood cancer: a report from the Childhood Cancer Survivor Study. Cancer 2011; 117:2559-68. [PMID: 21484777 DOI: 10.1002/cncr.25797] [Citation(s) in RCA: 112] [Impact Index Per Article: 8.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/05/2010] [Revised: 10/04/2010] [Accepted: 10/25/2010] [Indexed: 11/08/2022]
Abstract
BACKGROUND Long-term survivors of childhood cancer are at risk for fatigue, sleep problems, and neurocognitive impairment, although the association between these outcomes has not been previously examined. METHODS Outcomes were evaluated in 1426 survivors from the Childhood Cancer Survivor Study using a validated Neurocognitive Questionnaire. Relative risks for neurocognitive impairment were calculated using demographic and treatment factors, and survivors' report on the Functional Assessment of Chronic Illness Therapy-Fatigue, the Short Form-36 Vitality Scale, the Pittsburgh Sleep Quality Index, and the Epworth Sleepiness Scale. RESULTS Neurocognitive impairment was identified in >20% of survivors, using sibling-based norms for comparison. Multivariate logistic regression models revealed that fatigue (risk ratio [RR], 1.34; 95% confidence interval [CI], 1.13-1.59), daytime sleepiness (RR, 1.68; 95% CI, 1.55-1.83), poor sleep quality (RR, 1.23; 95% CI, 1.01-1.49), and decreased vitality (RR, 1.75; 95% CI 1.33-2.30) were all associated with impaired task efficiency. Likewise, fatigue (RR, 1.77; 95% CI, 1.23-2.55), sleepiness (RR, 1.38; 95% CI, 1.14-1.67), and decreased vitality (RR, 3.08; 95% CI, 1.98-4.79) were predictive of emotional regulation problems. Diminished organization was associated with increased sleepiness (RR, 1.80; 95% CI, 1.31-2.48) and decreased vitality (RR, 1.90; 95% CI, 1.37-2.63). Impaired memory was associated with poor sleep quality (RR, 1.45; 95% CI, 1.19-1.76), increased sleepiness (RR, 2.05; 95% CI, 1.63-2.58), and decreased vitality (RR, 2.01; 95% CI, 1.42-2.86). The impact of fatigue, sleepiness, sleep quality, and vitality on neurocognitive outcomes was independent of the effects of cranial radiation therapy, steroids and antimetabolite chemotherapy, sex, and current age. CONCLUSIONS Neurocognitive function in long-term survivors of childhood cancer appears particularly vulnerable to the effects of fatigue and sleep disruption. These findings suggest sleep hygiene should be emphasized among survivors, as it may provide an additional mechanism for intervention to improve neurocognitive outcomes.
