Mindfulness Based Cognitive Training in Children and Adolescents With ADHD

Attention-deficit/hyperactivity disorder (ADHD) is one of the most common neurodevelopmental disorders, with a pooled worldwide prevalence of 7.2% among children. Although medication and behavioral therapy, have been shown to be effective for reducing core symptoms, about 30% of patients with ADHD would not achieve the treatment response and symptomatic remission. Additionally, some children can experience sides effects related to medication. Therefore, other psychological approaches such as Mindfulness based interventions (MBIs) have been designed for the management of ADHD. Recent research showed that ADHD is associated with autonomic nervous system dysregulation, characterized by reduced vagally mediated-HRV, in response to a task demand. HRV is an accurate, non-invasive, cost-effective quantitative biomarker of autonomic nervous system (ANS) activity. There is evidence that MBIs could significantly reduce ADHD core symptoms and may enhance HRV through increased parasympathetic modulation. No studies have jointly examined the differential effect of MBIs on ADHD core symptoms, task related-HRV and mood. The aim of this study is to assess the effectiveness of a single-session of mindfulness based cognitive training on CVC, core symptoms and mood in children and adolescents with ADHD, aged 6 y-17y, referred to an outpatient Romanian Child and Adolescent Psychiatric Unit by mental health professionals, teachers and/or parents.

Neurophysiological Markers of Pediatric Irritability and Its Response to Intervention

There has been an increasing focus on the adverse impacts of irritability, defined as increased tendency towards anger. Irritability worsens peer relationships, family functioning, academic performance and is a risk factor for depression, suicide and substance use and is one of the main reasons why children get referred for treatment. It has been identified as transdiagnostic entity meriting investigation as a treatment target for personalized intervention given its prevalence and morbidity. Most children with prominent irritability also meet criteria for Attention Deficit Hyperactivity Disorder (ADHD) but only a subset of children with ADHD manifest impairing levels of irritability. Irritability levels are only minimally correlated with severity of ADHD symptoms suggesting that irritability is not simply a manifestation of severe ADHD. The first line treatment for irritability in children with ADHD is to optimize the dose of the CNS stimulant. However, there is great heterogeneity in response, with baseline mood lability being the best marker for both improving and worsening irritability. In addition, increased irritability is one of the most common reasons why parents stop these medications. The unpredictability in response to CNS stimulants has led to the increasing use of antipsychotics and other non-evidence based treatments for ADHD. It is unknown what drives this heterogeneity in response in part because little is known about the underlying causal mechanisms for irritability in youth with ADHD. Two areas theorized to contribute to irritability include impairments in learning from experience (instrumental learning) and sensitivity to reward and loss.1 There are objective methods for measuring these domains in children through the use of even-related potentials (ERPs)- synchronous neural activity in response to a stimulus. Reward positivity (RewP) is an ERP component occurring in response to feedback on task performance that can be broken down to separate reward and loss components. Irritability is thought to arise due to the combination of an enhanced drive for reward coupled with an excessive response to loss. No prior work has examined associations of RewP with irritability in ADHD. However, abnormalities in RewP and elevated irritability have both been established as risk factors for depression, suggesting that RewP may also predict irritability. Error related negativity (ERN) reflects the preconscious detection of potential conflict serving as an early warning signal for errors. Error detection is one of the first steps for instrumental learning. It is impaired in some youth with ADHD, with a suppressed ERN correlated with reduced error processing. CNS stimulants improve ERN amplitude and impaired error processing. We theorize that abnormalities in RewP and ERN in children with ADHD will serve as respective markers for severity of irritability and subsequent treatment response to CNS stimulants. If successful, we will have identified a causal pathway for irritability that will aide treatment development and identified a reliable biomarker for the current first line treatment for irritability in ADHD (CNS Stimulants), while providing care to a significantly impaired group of local children for whom few evidence-based treatments exist.

Influence of Circadian Clock on Hormonal, Metabolic, Neurocognitive Markers in Adolescents With and Without Diabetes

Type 1 diabetes mellitus (T1DM), makes its appearance during childhood and youth, but management implications last till late adulthood. Its treatment includes the combination of multiple daily glucose measurements, insulin administration and balanced nutrition. The goals of therapy are to achieve glycemic control (HbA1c < 7.5%), and minimal glycemic excursions. Furthermore, recent studies imply that keeping HbA1c within target range is not sufficient to prevent complications, attributed mainly to blood glucose level fluctuating from high to low, associated with food intake and adolescents behavior. The current implication of glycemic control on the central nervous system (CNS) includes abnormal electrical brain activity, structural changes in brain's white and grey matter, and cognitive impairment. Still, little is known on the effect of sleep pattern, including circadian rhythm reversal ("biological clock) on asymptomatic glycemic excursions, and on CNS functions. There is no data regarding the association of the biologic clock on CNS functionality among adolescents, nonetheless among T1DM adolescents, for whom behavior and circadian rhythm alterations may have harmful effect. The investigators propose a cross-over designed study by examining adolescents with and without T1DM during 2 weeks of regular sleeping pattern (night sleep), and during 2 weeks of sleeping during the day as happens during summer vacation. The main objective of the proposed study is to offer proof of the clinical and metabolic relevance and cognitive effects of the reversal of the circadian clock in adolescents with and T1DM during summer vacations and weekends. Study is designed to demonstrate a difference among healthy and diabetics during reversed night/day circadian clocks in the time spent within target range of glucose, performance on neuro cognitive tasks, electrical brain activity, and hormonal profile.

The Effects of a Single Dose of Methylphenidate on Motor Performance

Aim: To evaluate the effects of MPH on young adults diagnosed with ADHD on different exercise performance tests. Hypothesis: MPH will have positive effects on motor tests requiring concentration. Methods: 200 healthy physical education students, 100 participants diagnosed with ADHD will serve as the treatment group and 100 non-ADHD diagnosed will serve as a control group. The study will be divided into two sub studies (100 participants each), in which, two motor tests will be evaluated (two agility tests and two motor accuracy tests). All participants will arrive for two sessions, and will perform two motor tests in each session. In the second session, half of the participants with ADHD (25 participants) will undergo another session of the same motor tests with their usual treatment (treatment group) and another half (25 participants) without their treatment (ADHD control group). The non-ADHD control group (50 participants) will perform the second session without medications - to assess a learning effect. Note, we are not planning on giving the medication to the participant, rather he/she will consume their own prescribed MPH by them self. Control treatment for ADHD participants will consist of not taking their medication before the motor test. For evaluation of physiological responses and perception of effort we will measure heart rate, temperature, blood pressure and RPE before and after motor tests.

Treating Sleep in Teens With ADHD

Sleep problems are common in adolescence and recognized as an international public health concern given their links to a range of adverse outcomes. Adolescents with attention-deficit/hyperactivity disorder (ADHD) experience more sleep problems than their peers, including delayed sleep onset, shorter sleep duration, poorer sleep quality, more sleep variability, and greater daytime sleepiness. Further, research conducted by the investigator's team has shown that sleep problems are strongly associated with - and causal contributors to - functional impairment in adolescents with ADHD, including increased mood, behavior, and academic problems. However, sleep problems are not currently addressed in any evidence-based treatment for adolescents with ADHD, and no study has evaluated an intervention targeting sleep problems in adolescents with ADHD. This is a notable gap in the field since consensus statements on sleep suggest that treating sleep problems may improve ADHD and associated impairments. Evidence-based cognitive-behavioral sleep interventions, including the Transdiagnostic Sleep and Circadian Intervention for Youth (TranS-C) intervention, are effective for improving sleep and associated impairments (e.g., attention, mood) in adolescents with sleep problems. However, these interventions have never been tested in adolescents with ADHD specifically. This will be the first to evaluate a cognitive-behavioral sleep intervention (TranS-C) in adolescents with ADHD who experience co-occurring sleep problems. This study will recruit 15 adolescents with ADHD and sleep problems to enroll in and complete an open trial of the TranS-C intervention to evaluate its feasibility, acceptability, and preliminary efficacy. Findings will provide key pilot data regarding treatment of sleep problems in adolescents with ADHD.

School Health Implementation Network: Eastern Mediterranean

Background An estimated 10-20% of children globally are affected by a mental health problem. Child mental health has been identified as a priority issue by the World Health Organization's Eastern Mediterranean Regional Office (WHO EMRO). Following consultations with international and regional experts and stakeholders, WHO EMRO developed an evidence-based School Mental Health Program (SMHP), endorsed by WHO EMRO member countries, including Pakistan. The federal and provincial health departments in Pakistan made recommendations for a phased implementation of the SMHP in a pilot district. In the formative phase of this program, a number of implementation challenges were identified by the stakeholders. Broadly, these included the need to operationalize and adapt the existing components of the intervention to the local context and to develop sustainable mechanisms for delivery of quality training and supervision. Informed by the results of a formative phase investigations, the SHINE scale-up research team adapted the SMHP (henceforth called Conventional SMHP or cSMHP) to address these implementation challenges. The enhanced version of the intervention is called Enhanced School Mental Health Program (eSMHP). Enhancements to cSMHP have occurred at two levels: A) Content enhancements, such as a collaborative care model for engaging parents/primary caregivers, strategies for teacher's wellbeing, and adaptation and operationalization of particular clinical intervention strategies and B) Technological enhancements which include adaptation of the training manual for delivery using an online training platform, and a 'Chat-bot' to aid the implementation of intervention strategies in classroom settings. Objectives The primary objective of the study is to evaluate the effectiveness of eSMHP in reducing socio-emotional difficulties in school-going children, aged 8-13, compared to cSMHP in Gujar Khan, a rural sub-district of Rawalpindi, Pakistan. The secondary objectives are to compare the cost-effectiveness, acceptability, adoption, appropriateness (including cultural appropriateness), feasibility, penetration and sustainability of scaled-up implementation of eSMHP and cSMHP. It is hypothesized that eSMHP will prove to be both more effective and more scalable than cSMHP. Study population The research is embedded within the phased district level implementation of the cSMHP in Rawalpindi, Pakistan. The study population will consist of children of both genders, aged 8-13 (n=960) with socio-emotional difficulties, studying in rural public schools of sub-district Gujar Khan in Rawalpindi. Design The proposed study design is a cluster randomized controlled trial (cRCT), embedded within the conventional implementation of the SMHP. Following relevant ethics committees and regulatory approvals, 80 eligible schools, stratified by gender, will be randomized into intervention and control arms with a 1:1 allocation ratio. Following informed consent from the parent/ primary caregiver, children will be screened for socio-emotional difficulties using Strengths and Difficulties Questionnaire (SDQ). 960 children scoring > 12 on the teacher-rated SDQ total difficulty scores and > 14 on the parent-rated SDQ total difficulty scores will be recruited and equally randomized into intervention and control arms (480 in each arm). Teachers in the intervention arm will receive training in eSMHP, whereas teachers in the active control will be trained in cSMHP. Trained teachers will deliver the program to children in their respective arms. Outcome measures Primary Outcome: The primary outcome is reduction in socio-emotional total difficulties scores, measured with the parent-rated SDQ, 9 months after commencing intervention delivery. Secondary Outcomes: Implementation data on acceptability, adoption, appropriateness (including cultural appropriateness), feasibility, penetration and sustainability outcomes will be collected from children, parents/primary caregivers, head teachers and teachers. In addition, data will be collected on self-reported Psychological Outcome Profiles (PSYCHLOPS)-KIDS to measure progress on psycho-social problems and wellbeing; annual academic performance; classroom absenteeism, stigmatizing experiences and parent-teacher interaction. Data on teachers' sense of efficacy and subjective well-being, and on the schools' psychosocial environment profile will be collected. All secondary outcome data will be collected at baseline and 9 months after commencing intervention delivery. Outcomes will be analyzed on an intention to treat basis. The role of various factors as potential mediators and moderators eSMHP effectiveness will be explored. Cost-effectiveness evaluation of SMHP shall be evaluated in terms of costs associated with implementation of eSMHP compared with cSMHP.
