Stratification of responses to tDCS intervention in a healthy pediatric population based on resting-state EEG profiles. Sci Rep 2023; 13:8438.

Abstract
Transcranial Direct Current Stimulation (tDCS) is a non-invasive neuromodulation technique with a wide variety of clinical and research applications. As increasingly acknowledged, its effectiveness is subject dependent, which may lead to time consuming and cost ineffective treatment development phases. We propose the combination of electroencephalography (EEG) and unsupervised learning for the stratification and prediction of individual responses to tDCS. A randomized, sham-controlled, double-blind crossover study design was conducted within a clinical trial for the development of pediatric treatments based on tDCS. The tDCS stimulation (sham and active) was applied either in the left dorsolateral prefrontal cortex or in the right inferior frontal gyrus. Following the stimulation session, participants performed 3 cognitive tasks to assess the response to the intervention: the Flanker Task, N-Back Task and Continuous Performance Test (CPT). We used data from 56 healthy children and adolescents to implement an unsupervised clustering approach that stratify participants based on their resting-state EEG spectral features before the tDCS intervention. We then applied a correlational analysis to characterize the clusters of EEG profiles in terms of participant's difference in the behavioral outcome (accuracy and response time) of the cognitive tasks when performed after a tDCS-sham or a tDCS-active session. Better behavioral performance following the active tDCS session compared to the sham tDCS session is considered a positive intervention response, whilst the reverse is considered a negative one. Optimal results in terms of validity measures was obtained for 4 clusters. These results show that specific EEG-based digital phenotypes can be associated to particular responses. While one cluster presents neurotypical EEG activity, the remaining clusters present non-typical EEG characteristics, which seem to be associated with a positive response. Findings suggest that unsupervised machine learning can be successfully used to stratify and eventually predict responses of individuals to a tDCS treatment.

Feasibility and tolerability of moderate intensity regular physical exercise as treatment for core symptoms of attention deficit hyperactivity disorder: a randomized pilot study. Front Sports Act Living 2023; 5:1133256. [PMID: 37255729 PMCID: PMC10225649 DOI: 10.3389/fspor.2023.1133256] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/28/2022] [Accepted: 04/21/2023] [Indexed: 06/01/2023] Open
Abstract
Background Attention deficit hyperactivity disorder (ADHD) is associated with sedentary lifestyle, low quality of life and low physical fitness. Studies in children with ADHD have shown that regular physical exercise can help reduce core ADHD symptoms, but evidence for this is lacking in adults. Although guidelines recommend multi-modal treatment, central stimulants (CS) remain the mainstay of treatment. CS are effective in the short-term, but their long-term efficacy remains to be established. There is thus huge unmet need for developing non-pharmacological treatment options, and for well-designed randomized controlled trials (RCTs). Objective The study aimed to test the feasibility and tolerability of structured moderate-intensity 12-week physical exercise program for adults with ADHD, as a prelude to an adequately powered RCT which includes long-term follow-up. Materials and methods Fourteen adults with ADHD were recruited, 9 randomized to an intervention group and 5 to a control group. The intervention group received physiotherapist-led 50-minute mixed exercise program, three times a week for 12 weeks, and the control group treatment as usual. Participants were assessed at baseline and after 6 and 12 weeks using clinical and physical evaluations, self-rating questionnaires, and functional magnetic resonance imaging (fMRI) together with paradigms that tested attention, impulsivity and emotion regulation. Results Three participants (21%) dropped out shortly after inclusion before receiving any intervention, while roughly 80% completed the intervention according to protocol. One participant from the intervention group participated in less than 60% of treatment sessions, and one who had done baseline fMRI was unwilling to do post-intervention imaging. Four participants in the intervention group (67%) reported increased stress in prioritizing the intervention due to time-management difficulties. Overall, consistent trends were observed that indicated the feasibility and potential benefits of the intervention on core ADHD symptoms, quality of life, body awareness, sleep and cognitive functioning. Conclusion Physiotherapist-led twelve-week regular physical exercise is a feasible and potentially beneficial intervention for adults with ADHD. There was a 20% drop-out initially and 67% of those who completed the intervention reported stress with time management difficulties due to participation. A third arm was thus added to the planned RCT where cognitive intervention administered by an occupational therapist will be given together with physical exercise.Clinical Trial Registration: https://clinicaltrials.gov, identifier NCT05049239.

Abstract
ABSTRACT Athletes of all ages may be affected by medical and mental health issues. Sports medicine physicians should be familiar with common conditions that may affect the well-being of athletes, such as attention-deficit/hyperactivity disorder (ADHD). ADHD behaviors have the potential to affect a person's ability to concentrate. It is likely that social and cognitive therapies combined with pharmacotherapy will be the most effective way to treat ADHD in athletes. Medications used for ADHD, especially stimulant types, are known to improve alertness, reaction time, anaerobic performance, and endurance, which would potentially improve athletic performance. Furthermore, stimulant medications may enable student athletes with ADHD to focus on academic studies for longer periods of time, beyond usual levels of fatigue, important for those who may be exhausted after practices and games. The purported performance enhancement effects and potential adverse effects of stimulant medications have prompted many sports governing bodies to ban prescription stimulants or establish strict rules for their use. Athletes taking physician-prescribed stimulants to treat ADHD need to provide the appropriate documentation for approval before competition or risk punitive measures. Physicians should strive to provide a high quality of care to athletes with ADHD through early diagnosis, appropriate and careful multidisciplinary treatment, and complete and timely documentation to facilitate continued sports participation.

[PMID: 35091797 DOI: 10.1007/s00431-021-04356-w] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/11/2021] [Revised: 12/16/2021] [Accepted: 12/17/2021] [Indexed: 11/03/2022]
Abstract
UNLABELLED Stimulants have become the most popular psychopharmacologic drugs used in therapy for attention-deficit/hyperactivity disorder (ADHD). Childhood and adolescence are crucial periods for optimizing bone health to prevent osteoporosis-related fractures in old age. However, controversy remains regarding the relationship between stimulant use and bone health. The present study was designed to examine the bone mineral content (BMC) and bone mineral density (BMD) of 5472 individuals aged 8-16 years with or without stimulant use based on National Health and Nutrition Examination Survey (NHANES) 2011-2018 data and to further assess the association between stimulant use and bone health. Among these, 284 (5.2%) participants were using stimulants. In analyses stratified by sex, the BMC and BMD at the level of the lumbar spine, pelvis, and total body were generally lower among stimulant users than among nonusers in males (all P < 0.001), while the differences were not statistically significant in females. In multivariable linear regression models, the increasing range of BMCs and BMDs with age was lower in participants using stimulants than in those not using stimulants after fully adjusting for potential confounding factors. Compared to participants not using stimulants, stimulant use ≥ 3 months was associated with significantly lower BMCs [lumbar spine: β = - 1.35, (95% CI: - 2.56, - 0.14); pelvis: β = - 9.06, (95% CI: - 15.21, - 2.91); and total: β = - 52.96, (95% CI: - 85.87, - 20.04)] and BMDs [pelvis: β = - 0.03, (95% CI: - 0.04, - 0.01), total: β = - 0.01, (95% CI: - 0.02, - 0.00)]. CONCLUSIONS Children and adolescents using stimulants exhibited reductions in BMC and BMD at the lumbar spine, pelvis, and total body compared to those who were not using stimulants, especially among males. WHAT IS KNOWN • Childhood and adolescence are crucial periods for optimizing bone health to prevent osteoporosis-related fractures in old age. • Controversy remains regarding the relationship between stimulant use and bone health. WHAT IS NEW • The bone mineral content and bone mineral density at the level of the lumbar spine, pelvis, and total body were generally lower among stimulant users than among nonusers in males, while the differences were not statistically significant in females. • Body mass index and serum alkaline phosphatase may be predictors for loss of bone mineral content and bone mineral density in stimulant users.

Abstract
Alleviating the multiple problems of children with autism spectrum disorder (ASD) and its comorbid conditions presents major challenges for the affected children, parents, and therapists. Because of a complex psychopathology, structured therapy and parent training are not always sufficient, especially for those patients with intellectual disability (ID) and multiple comorbidities. Moreover, structured therapy is not available for a large number of patients, and pharmacological support is often needed, especially in those children with additional attention deficit/hyperactivity and oppositional defiant, conduct, and sleep disorders.

Abstract
Objective: Clinicians frequently rely upon the results of self-report rating scales when making the diagnosis of ADHD; however, little research exists regarding the ability of self-report measures to accurately differentiate ADHD from other disorders. Method: This present study investigated the ability of the Conners' Adult ADHD Rating Scale (CAARS) to discriminate between 249 postsecondary students with carefully diagnosed ADHD and 507 clinical controls. Results: The overall discriminant validity of the CAARS was 69%, and it had an unacceptably high false positive and false negative rate. At lower prevalence rates, a high score on the CAARS has only a 22% chance of accurately identifying individuals with ADHD. Conclusion: Although the CAARS is an adequate screening measure, it should not be the main method by which a diagnosis is made, as it frequently misidentifies individuals with other psychological complaints as having ADHD. Implications for clinical practice are discussed.

Abstract
Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder that manifests in difficulties with sustaining attention in tasks and/or hyperactivity/impulsivity. Prevalence rates vary and difficulties in objectively diagnosing ADHD may lead to overdiagnosis or underdiagnosis. Assessment should include a comprehensive evaluation, including history, physical, psychological evaluation, and questionnaires for ADHD. Stimulant medications are effective for treatment, but their use, side effects, and potential for misuse and abuse are a concern, particularly in athletes. Athletes and physicians also need to be aware of the governing body's drug policy for the sport.

Abstract
Attention deficit hyperactivity disorder (ADHD) is a neurodevelopmental condition being diagnosed in increasing numbers. While the link between sleep and ADHD is of increasing interest, the relationship between sleep duration and ADHD remains largely uninvestigated in adult populations. We evaluated the association between self-reported sleep duration and ADHD in a cohort of American adults using data from the 2012 National Health Interview Survey (Centers for Disease Control and Prevention, 2012). Of the 30,858 participants eligible for our analyses, there were 1,122 cases of ADHD. Elevated and diminished sleep durations were both associated with increased odds of reporting ADHD (≤ 6 hr: OR = 1.50, 95% CI 1.19, 1.90; ≥ 9 hr: OR = 1.49, 95% CI 1.26, 1.75) in fully adjusted models. Future prospective studies are necessary to further examine this association in adult patients.

Abstract
Attention Deficit/Hyperactivity Disorder (ADHD), the most ubiquitous mental health problem in children, has been associated with poor self-esteem. Psychosocial interventions have aimed to improve self-esteem among this group, with the aim of reducing the development of comorbid depression and anxiety. The present study implemented a randomized control design to examine the possibility of Animal Assisted Interventions (AAI) as a viable approach to improving self-esteem among children with ADHD. Children's self-esteem across multiple domains as measured by the Self-Perception Profile for Children was evaluated (n = 80, ages 7-9, 71% male). To test the hypothesis that AAI improves self-esteem, stratified Wilcoxon Signed-Rank Tests (SAS NPAR1WAY procedure) were used to compare pre- to post-treatment ratings. Analyses indicated that scores of children's self-perceptions in the domains of behavioral conduct, social, and scholastic competence, were significantly increased from baseline to post-treatment in the AAI group (z = 2.320, p = .021, z = 2.631, p = .008, and z = 2.541, p = .011, respectively), whereas pre-post-treatment differences in self-perceptions were not found for the children in the control group without AAI. Findings suggest that AAI is a viable strategy for improving ratings of self-perceived self-esteem in children with ADHD.

Abstract
Several international guidelines indicate stimulants, including methylphenidate (MPH), amphetamines and derivatives, modafinil, and armodafinil among the second-third-line choices for bipolar depression. Efficacy of stimulants has been also reported for the management of residual depressive symptoms such as fatigue and sleepiness and for the management of affective, cognitive, and behavioral symptoms in children and adult bipolar patients with comorbid ADHD. Few case reports show positive results with MPH in the treatment of resistant mania. Finally, MPH might be an option in some bipolar forms observed in psychiatric presentations of frontotemporal dementia and traumatic brain injury. In spite of these preliminary observations, the use of stimulants in bipolar patients is still controversial. Potential of misuse and abuse and mood destabilization with induction of (hypo)manic switches, mixed states, and rapid cycling are the concerns most frequently reported. Our aims are to summarize available literature on this topic and discuss practical management implications.

Abstract
OBJECTIVE The aim of this study was to assess the type and frequency of adverse events (AEs) in children with attention-deficit/hyperactivity disorder (ADHD) treated with methylphenidate or atomoxetine over a 5-year period in a large naturalistic study. METHODS We draw on data from the Italian ADHD Registry, a national database for postmarketing phase IV pharmacovigilance of ADHD medications across 90 centers. AEs were defined as severe or mild as per the classification of the Italian Medicines Agency. AE frequency in the two treatment groups was compared using incidence rates per 100 person-years (IR100PY) and incidence rate ratios (IRRs). Mantel-Haenszel adjusted IRRs were calculated to control for psychiatric comorbidity. RESULTS A total of 1350 and 753 participants (aged 6-18 years, mean age 10.7 ± 2.8) were treated with methylphenidate and atomoxetine, respectively, from 2007 to 2012. Ninety participants (7 %) were switched from methylphenidate to atomoxetine, and 138 (18 %) from atomoxetine to methylphenidate. Thirty-seven children treated with atomoxetine and 12 with methylphenidate had their medication withdrawn. Overall, 645 patients (26.8 %) experienced at least one mild AE (including decreased appetite and irritability, for both drugs) and 95 patients (3.9 %) experienced at least one severe AE (including severe gastrointestinal events). IR100PY were significantly higher in the atomoxetine-treated group compared with the methylphenidate-treated group for a number of mild and severe AEs and for any severe or mild AEs. After controlling for comorbidities, IRR was still significantly higher in the atomoxetine group compared with the methylphenidate group for a number of mild (decreased appetite, weight loss, abdominal pain, dyspepsia, stomach ache, irritability, mood disorder and dizziness) and severe (gastrointestinal, neuropsychiatric, and cardiovascular) AEs. CONCLUSIONS In this naturalistic study, methylphenidate had a better safety profile than atomoxetine.

Sex differences in subjective and objective responses to a stimulant medication (methylphenidate): Comparisons between overweight/obese adults with and without binge-eating disorder. Int J Eat Disord 2016; 49:473-81. [PMID: 26691428 DOI: 10.1002/eat.22493] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/30/2015] [Revised: 11/21/2015] [Accepted: 11/22/2015] [Indexed: 11/06/2022]
Abstract
OBJECTIVE The purpose of this study was to examine sex differences in response to a single dose of a psychomotor-stimulant medication (methylphenidate: MP) and to assess whether expected differences were moderated by binge-eating disorder (BED) status. It is anticipated that findings will shed light on factors that contribute to response variation in the use of stimulant pharmacotherapy to treat BED. METHOD The study employed a double-blind, drug-placebo, cross-over design in overweight/obese adults with BED (n = 90) and without BED (n = 108). Emotional/mood ratings were assessed every 15 minutes after oral administration of the drug/placebo, and appetite, cravings, and consumption were assessed during a laboratory-based snack-food challenge. RESULTS Women reported earlier and more sustained "overall" effects of the drug-including "feeling high"-than the men. There was also a significantly greater suppression in appetite ratings, food cravings, and food consumption from the placebo to the drug condition among the women. Indeed, among men there were no significant differences between the two conditions on any of the food-related variables. BED status also did not moderate any of the drug-placebo differences. DISCUSSION These findings are relevant to the use of stimulant pharmacotherapy for BED, and raise the possibility that overweight/obese men may be relatively less responsive to this form of treatment. © 2015 Wiley Periodicals, Inc.

Abstract
INTRODUCTION Attention deficit/hyperactivity disorder (ADHD) persists into adulthood in about 50% of the affected children, with high rates of comorbidity with bipolar disorder (BD). Stimulants and atomoxetine (ATX) are effective treatments for ADHD, but their use in adults with comorbid BD (ADHD-BD) has not been extensively studied and may be problematic. AREAS COVERED The aim of the paper is to summarize the available literature regarding the use of these medications in ADHD-BD adult patients. Results of randomized-controlled and open-label trials, case reports, and case series are reviewed. We also reviewed data relative to some specific issues of this comorbidity in adults, especially substance use disorder, malingering, and stimulants misuse. EXPERT OPINION ADHD-BD may be associated with more severe symptoms, course, and worst outcome of both conditions. The frequent coexistence with alcohol and substance abuse may further complicate treatment management. Stimulants are the most effective medications for ADHD, but their use may be contraindicated in the presence of a comorbid drug abuse or in patients that simulate or exaggerate ADHD symptoms in order to obtain stimulants for diversion or abuse. ATX may be effective in the treatment of ADHD symptoms in BD patients, with a modestly increased risk of (hypo)manic switches and destabilization of the mood disorder when utilized in association with mood stabilizers. In the majority of the cases, a hierarchical approach is desirable, with mood stabilization preceding the treatment of ADHD symptoms. Although systematic trials on the use of stimulants and ATX in ADHD-BD comorbidity in adulthood are necessary, both treatments should be considered possible options to be carefully evaluated once the patient has been stabilized.

Abstract
This chapter reviews methylphenidate misuse, abuse, dependence, diversion, and malingering associated with its use as a prescription medication for attention-deficit/hyperactivity disorder and the nonmedical use linked to its stimulant effects. Methylphenidate-induced regional elevations in brain dopamine appear to be integral to both efficacy in attention-deficit/hyperactivity disorder and potential for abuse, raising potential concerns for drug safety and prescription drug diversion costs associated with nonmedical use. Regardless, methylphenidate is an important treatment option, and detecting malingering for the purpose of illicit access to methylphenidate for subsequent misuse or diversion is a difficult challenge. Also discussed are the effects of methylphenidate in patients with comorbid substance use disorder and the potential linkage of methylphenidate use with subsequent substance abuse. The current data suggest that methylphenidate misuse and diversion are common health-care problems with a stimulant prescription drug diversion prevalence of approximately 5-10 % of high school students and 5-35 % of college students. The effectiveness and speed of action of methylphenidate are deemed desirable to enhance attention and focus performance for activities such as studying for exams, but methylphenidate is also misused recreationally. These data suggest a need for close screening and therapeutic monitoring of methylphenidate use in the treatment of attention-deficit/hyperactivity disorder.
