Using antipsychotics for behavioral problems in children

Challenging Behaviors in Children with Nonverbal Autism: A Questionnaire to Guide the Design of a Wearable Device for Biomarker Recording

Children with non- or minimally verbal autism (nmvASD) commonly display sensory and emotional dysregulations leading to extremely stressful situations that trigger challenging behaviors which are often difficult to treat. Nonetheless, this population remains rarely studied in clinical research. Recent methods use electrophysiological biomarkers as diagnostic tools to detect stress signals, which may be useful in anticipating situations or conditions leading to challenging behaviors in nmvASD. A specific questionnaire was created in order to identify the characteristics of nmvASD children and gather the opinions of future users (parents and caregivers) on the design of a wearable device able to collect stress-related electrophysiological data. The results indicate that approximately 67.5% of respondents (n = 40) would be interested in such a device, both in outpatient and inpatient settings. In 70% of cases, prolonged contact with an object on the trunk is always well accepted by the child. This location was also preferentially chosen by 57.5% of respondents for such a wearable device. The presence of wires could be problematic in 82.5% of cases. About 65% of respondents find it far better to integrate these wearable devices directly into the clothing. These results will help in the development of devices specifically developed for the nmvASD population to enhance their care for behavioral disorders and based on user-center design.

Excess cardiometabolic risk in children and adolescents initiating antipsychotic treatment compared to young adults: results from a nationwide cohort study

Antipsychotic treatment is associated with cardiometabolic risks that may be especially detrimental to children and adolescents. In this Danish population-based cohort study, we included individuals with psychiatric diagnoses who initiated antipsychotics in 2000-2021 at age 6-31 years. We assessed the risk of cardiometabolic adverse events up to 10 years following incident exposure to antipsychotics, compared to age- and sex-matched unexposed individuals with psychiatric diagnoses. Cox regression models were used to calculate hazard ratios (HRs) after adjustment using high-dimensional propensity scores, including age, sex, calendar time, hospital diagnoses, and prescription drug use. HRs were compared between incident exposure in youths (6-17 years) and young adults (18-31 years), and between incident exposure in children (6-11 years) and adolescents (12-17 years). The total cohort consisted of 335,093 individuals, including 36,092 subjects exposed to antipsychotics (children and adolescents: 8,547, mean follow-up: 6.8±3.2 years; young adults: 27,545, mean follow-up: 6.5±3.4 years) and 299,001 age-, sex- and calendar-matched unexposed subjects. The incidence rate of cardiometabolic events was higher for young adults initiating antipsychotics than for children and adolescents (23.2 vs. 14.1 events/1,000 person-years). However, the adjusted excess risk of cardiometabolic events was significantly higher in exposed compared to unexposed children and adolescents (HR=1.87, 95% CI: 1.71-2.05) than in exposed compared to unexposed young adults (HR=1.46, 95% CI: 1.40-1.51) (p<0.001). The excess risk of cardiometabolic events was even higher when antipsychotic treatment was initiated before age 12 years (HR=2.44; 95% CI: 1.99-2.98) than at age 12-17 years (HR=1.69, 95% CI: 1.52-1.87) (p=0.012). Concerning specific cardiometabolic outcomes, there was an effect of age at antipsychotic initiation on the risks of metabolic syndrome (p=0.011) and obesity (p<0.001), that were higher among children and adolescents than young adults. Thus, initiation of antipsychotic treatment before age 18 years is associated with an excess risk of cardiometabolic events compared to age- and sex-matched youths with psychiatric disorders but unexposed to antipsychotics. The excess cardiometabolic risk is significantly higher than that of individuals who start antipsychotic treatment in early adulthood, and significantly higher for treatment onset in childhood compared to adolescence. On the basis of these findings, recommendations are provided about the use of antipsychotics in children and adolescents.

Continuous oral olanzapine or clozapine treatment initiated in adolescence has differential short- and long-term impacts on antipsychotic sensitivity than those initiated in adulthood

One of the major discoveries in recent research on antipsychotic drugs is that antipsychotic treatment in adolescence could induce robust long-term alterations in antipsychotic sensitivity that persist into adulthood. These long-term impacts are likely influenced by various factors, including the "diseased" state of animals, sex, type of drugs, mode of drug administration, and age of treatment onset. In this study we compared the short- and long-term behavioral effects of 21-day continuous oral olanzapine (7.5 mg/kg/day) or clozapine (30.0 mg/kg/day) administration in heathy or maternal immune activated adolescent (33-53 days old) or adult (80-100 days old) rats of both sexes. We used a conditioned avoidance response model to assess the drug-induced alterations in antipsychotic sensitivity. Here, we report that while under the chronic drug treatment period, olanzapine progressively increased its suppression of avoidance responding over time, especially when treatment was initiated in adulthood. Clozapine's suppression depended on the age of drug exposure, with treatment initiated in adulthood showing a suppression while that initiated in adolescent did not. After a 17-day drug-free interval, in a drug challenge test, olanzapine treatment initiated in adolescence caused a decrease in drug sensitivity, as reflected by less avoidance suppression (a tolerance effect); whereas that initiated in adulthood appeared to cause an increase (more avoidance suppression, a sensitization effect). Clozapine treatments initiated in both adolescence and adulthood caused a similar tolerance effect. Our findings indicate that the same chronic antipsychotic treatment regimen initiated in adolescence or adulthood can have differential short- and long-term impacts on drug sensitivity.

Pharmacogenomics and non-genetic factors affecting drug response in autism spectrum disorder in Thai and other populations: current evidence and future implications

Autism spectrum disorder (ASD) may affect family and social life profoundly. Although there is no selective pharmacotherapy for ASD, the Food and Drug Administration (FDA) has recommended risperidone/aripiprazole to treat the associated symptoms of ASD, such as agitation/irritability. Strong associations of some pharmacokinetic/pharmacodynamic gene variants, e.g., CYP2D6 and DRD2, with risperidone-induced hyperprolactinemia have been found in children with ASD, but such strong genetic associations have not been found directly for aripiprazole in ASD. In addition to pharmacogenomic (PGx) factors, drug-drug interactions (DDIs) and possibly cumulative effects of DDIs and PGx may affect the safety or effectiveness of risperidone/aripiprazole, which should be assessed in future clinical studies in children with ASD. Reimbursement, knowledge, and education of healthcare professionals are the key obstacles preventing the successful implementation of ASD pharmacogenomics into routine clinical practice. The preparation of national and international PGx-based dosing guidelines for risperidone/aripiprazole based on robust evidence may advance precision medicine for ASD.

An expert opinion on the pharmacological interventions for Disruptive Mood Dysregulation Disorder (DMDD)

INTRODUCTION

Disruptive Mood Dysregulation Disorder (DMDD) was officially introduced as a new diagnostic entity in the Diagnostic and Statistical Manual of Mental Disorder, Fifth Edition (DSM-5), under the category of depressive disorders.

AREAS COVERED

A comprehensive overview and a critical commentary on the currently investigated psychopharmacological approaches for the treatment of DMDD have been here provided.

EXPERT OPINION

Behavioral and psychosocial interventions should be considered as first-line treatment strategies. When ineffective or partially effective, psychopharmacological strategy is recommended. Overall, pharmacological strategy should be preferred in those individuals with psychiatric comorbidities (e.g. ADHD). Indeed, so far published studies on pharmacological strategies in DMDD are scant and heterogeneous (i.e. age, assessment tools, symptomatology profile, comorbidity, and so forth). Therefore, DMDD psychopharmacological guidelines are needed, particularly to guide clinicians toward the patient's typical symptom profile who could benefit from psychopharmacological strategy.

Psychotropic Medication Use in Children and Adolescents With Type 1 Diabetes

Importance

Children and adolescents with type 1 diabetes (T1D) face elevated risks of psychiatric disorders. Despite their nonnegligible adverse effects, psychotropic medications are a common cost-effective approach to alleviating psychiatric symptoms, but evidence regarding their dispensation to children and adolescents with T1D remains lacking.

Objective

To examine the trends and patterns of psychotropic medication dispensation among children and adolescents with T1D in Sweden between 2006 and 2019.

Design, Setting, and Participants

This cohort study used data from multiple Swedish registers. The main study cohort included children and adolescents residing in Sweden from 2006 to 2019 and was followed up until the earliest of December 31, 2019, 18th birthday, emigration, or death. Data analyses were conducted from November 1, 2022, to April 30, 2023.

Exposures

Type 1 diabetes.

Main Outcomes and Measures

The primary outcomes were trends and patterns of psychotropic medication dispensation (including antipsychotics, antidepressants, anxiolytics, hypnotics, mood stabilizers, and medications for attention-deficit/hyperactivity disorder [ADHD]), psychotropic medication initiation, and history of neurodevelopmental and psychiatric diagnosis. Cumulative incidence curves and Cox proportional hazard models were used to estimate the aggregated incidence and hazard ratios of medication initiation after diabetes onset.

Results

Of 3 723 745 children and adolescents (1 896 199 boys [50.9%]), 13 200 (0.4%; 7242 boys [54.9%]) had T1D (median [IQR] age at diagnosis, 11.1 [7.6-14.7] years). Between 2006 and 2019, psychotropic medication dispensation increased from 0.85% (95% CI, 0.65%-1.10%) to 3.84% (3.11%-4.69%) among children and from 2.72% (95% CI, 2.15%-3.39%) to 13.54% (95% CI, 12.88%-14.23%) among adolescents with T1D, consistently higher than their peers without T1D. The most commonly dispensed medications included hypnotics, ADHD medications, anxiolytics, and selective serotonin reuptake inhibitors, and all exhibited increasing trends. For those with T1D, psychiatric care was the primary prescription source, and up to 50.1% of treatments lasted more than 12 months. In addition, children and adolescents with T1D showed higher cumulative incidence and hazard ratios of medication initiation after diabetes onset than their same-age and same-sex counterparts.

Conclusions and Relevance

This cohort study found an increasing trend in psychotropic medication dispensation among children and adolescents with T1D from 2006 to 2019, persistently higher than those without T1D. These findings call for further in-depth investigations into the benefits and risks of psychotropic medications within this population and highlight the importance of integrating pediatric diabetes care and mental health care for early detection of psychological needs and careful monitoring of medication use.

Antioxidant Behavioural Phenotype in the Immp2l Gene Knock-Out Mouse

Mitochondrial dysfunction is strongly associated with autism spectrum disorder (ASD) and the Inner mitochondrial membrane protein 2-like (IMMP2L) gene is linked to autism inheritance. However, the biological basis of this linkage is unknown notwithstanding independent reports of oxidative stress in association with both IMMP2L and ASD. To better understand IMMP2L's association with behaviour, we developed the Immp2lKD knockout (KO) mouse model which is devoid of Immp2l peptidase activity. Immp2lKD -/- KO mice do not display any of the core behavioural symptoms of ASD, albeit homozygous Immp2lKD -/- KO mice do display increased auditory stimulus-driven instrumental behaviour and increased amphetamine-induced locomotion. Due to reports of increased ROS and oxidative stress phenotypes in an earlier truncated Immp2l mouse model resulting from an intragenic deletion within Immp2l, we tested whether high doses of the synthetic mitochondrial targeted antioxidant (MitoQ) could reverse or moderate the behavioural changes in Immp2lKD -/- KO mice. To our surprise, we observed that ROS levels were not increased but significantly lowered in our new Immp2lKD -/- KO mice and that these mice had no oxidative stress-associated phenotypes and were fully fertile with no age-related ataxia or neurodegeneration as ascertained using electron microscopy. Furthermore, the antioxidant MitoQ had no effect on the increased amphetamine-induced locomotion of these mice. Together, these findings indicate that the behavioural changes in Immp2lKD -/- KO mice are associated with an antioxidant-like phenotype with lowered and not increased levels of ROS and no oxidative stress-related phenotypes. This suggested that treatments with antioxidants are unlikely to be effective in treating behaviours directly resulting from the loss of Immp2l/IMMP2L activity, while any behavioural deficits that maybe associated with IMMP2L intragenic deletion-associated truncations have yet to be determined.

The long-lasting effects of early antipsychotic exposure during juvenile period on adult behaviours - A study in a poly I:C rat model

Second generation antipsychotic drugs including aripiprazole, olanzapine and risperidone are prescribed increasingly (mostly off-label) to treat various mental disorders in children and adolescents. Early treatment with antipsychotics during this period may have long-lasting behavioural impacts, but to date there have been only limited investigations. Maternal infection could be implicated in the aetiology of various mental disorders including schizophrenia. Exposure of pregnant rodents to polyriboinosinic-polyribocytidylic acid (Poly I:C) causes schizophrenia-like behavioural abnormalities and neurodevelopmental conditions such as autism spectrum disorders in offspring. This study, using a Poly I:C rat model, investigated the long-lasting effects of early aripiprazole, olanzapine and risperidone treatment in the childhood/adolescent period (postnatal day 22-50) on adult behaviours of male rats. The study showed that early treatment with three antipsychotics had different effects on long-term behavioural changes in adults. Prenatal Poly I:C exposure (5 mg/kg) at gestation day 15 caused deficits in pre-pulse inhibition and social interaction, as well as cognitive impairments, that could be partially improved by early antipsychotic treatment in the juvenile period. Early antipsychotic treatment during the childhood-adolescent period resulted in similar long-lasting effects on pre-pulse inhibition, anxiety- and depressive-related behaviours in both Poly I:C and healthy (control) male rats. Overall, these results suggest that both prenatal Poly I:C exposure and early antipsychotic treatment in the childhood/adolescent period had long-lasting effects on adult behaviours of male rats, while early antipsychotic treatment could partly prevent the onset of behavioural abnormalities resulting from prenatal insult.

Pediatric Off-Label Antipsychotic Use for Attention-Deficit/Hyperactivity Disorder

PURPOSE

Off-label antipsychotic use for behavioral symptoms in pediatric attention-deficit/hyperactivity disorder (ADHD) poses safety concerns, and evidence to support such use is limited. This study aims to investigate the risk of off-label antipsychotic use associated with comorbid disruptive behavior disorder (DBD) among a cohort of youth with ADHD.

METHODS

A cohort study was conducted using IQVIA PharMetrics Plus for Academics data from 2007 to 2020. Youth 5 to 15 years of age at the index ADHD visit were included in the cohort. The index ADHD visit meets at least 1 of the following criteria: (1) 1 inpatient ADHD visit, (2) 2 outpatient ADHD visits within 90 days, or (3) an ADHD medication prescription fill within 30 days of an outpatient ADHD visit. We excluded youth who had a diagnosis of DBD or a US Food and Drug Administration (FDA)-approved indication for antipsychotics at baseline. Youth were followed up until antipsychotic initiation or were censored at a loss of coverage, receipt of an FDA-indicated diagnosis, or end of the study. A Cox proportional hazards regression model with DBD as a time-varying covariate estimated the hazard of antipsychotic use after the index ADHD visit.

FINDINGS

Of 41,098 youth with ADHD who met the study criteria, 4557 were diagnosed with DBD during follow-up. The incidence of antipsychotic initiation was 19.6 (95% CI, 18.7- 20.5) per 1000 person-years. After adjustment for baseline covariates, the hazard ratio of antipsychotic initiation associated with DBD was 4.64 (95% CI, 4.15-5.18).

IMPLICATIONS

Antipsychotic use among youth with ADHD is more likely in the presence of DBD, suggesting that an off-label use is for behavior problems.

Clinical Safety and Treatment of Severe Aggression: Behavioral-Pharmacological Intervention Evaluation in a Young Adult With Autism Spectrum Disorder

This case study concerned clinical safety and behavioral-pharmacological intervention with an 18-year-old man who had autism spectrum disorder and high-frequency aggression toward care providers at a specialized school. A multicomponent behavior support plan included antecedent, differential reinforcement, environmental modification, and physical management procedures subsequently combined with psychotropic medication (aripiprazole). Clinical safety components emphasized comprehensive care provider training, continuous supervision, function-based treatment, and prevention-focused strategies. The behavioral-pharmacological intervention eliminated implementation of aggression-contingent physical restraint and was associated with increased transition compliance during the school day. Throughout the 7.5 months duration of the study, there were no injuries to the participant or other students and a single injury was sustained by one care provider. Intervention effects were long-standing, and care providers rated their training, implementation fidelity, and therapeutic outcome favorably.

Florida Medicaid Children's Receipt of First-Line Psychosocial Care Prior to Antipsychotic Initiation

BACKGROUND AND OBJECTIVE

First-line, nonpharmacological therapy is recommended for many pediatric mental health (MH) conditions prior to initiating antipsychotic prescription therapies. Many children do not receive these recommended services, despite the known association between antipsychotic medications and metabolic dysfunction. The main objective of this study was to quantify the association among children's MH diagnosis categories, sociodemographic characteristics and receipt of first-line psychosocial care among children in Florida Medicaid METHODS: Florida Medicaid enrollment, healthcare and pharmacy claims were used for this multivariate analysis. Children were assigned to condition clusters wherein related diagnoses were grouped into clinically relevant categories. A total of 7704 children were included in the final analysis.

RESULTS

Twenty-four percent of children in Florida Medicaid do not receive first-line, nonpharmacological psychosocial care. Age was significantly associated with not receiving psychosocial services, with older children less likely to receive. Non-Hispanic White children as well as those living in rural areas had lower odds of receiving behavioral intervention prior to initiating antipsychotics. Children with mood-disorders, behavior problems, anxiety and stress related disorders were more likely to receive first-line psychosocial care.

CONCLUSIONS

This study provides an important understanding of the variability in receipt of first-line psychosocial care before antipsychotic medication initiation among children in Medicaid based on sociodemographic and MH health characteristics. These analyses can be used to develop quality improvement initiatives targeted toward children that are most vulnerable for not receiving recommended care.

Impact of Antipsychotic Use on Readmission Rates in Children and Adolescents With Autism Spectrum Disorder and Irritability

Background

Risperidone and aripiprazole have been established as standard pharmacological treatments for irritability and associated aggressive behaviors in individuals with autism spectrum disorder (ASD), and are the only drugs approved by the United States Food and Drug Administration for those purposes. However, the rates of readmission with the use of these drugs in the pediatric population have not been studied, leaving a gap in the knowledge of antipsychotic effects. Readmission rates are a valuable metric of treatment efficacy that also reflect the financial burden, morbidity, and medical complications associated with multiple hospitalizations.

Methodology

A retrospective study was conducted in 65 Hospital Corporation of America Healthcare hospitals within the United States from 2016 to 2019. Patients aged 6-17 years with a diagnosis of ASD with irritability were included. The primary outcome was 30-, 60-, and 90-day readmission rates. Chi-square tests of independence and post-hoc analyses were used to assess the relatedness between readmission rate and antipsychotic use, as well as the type of antipsychotic medication if used. A binary regression analysis was used to analyze the relationship between demographic characteristics and readmission rate in this population. Patients on antidepressants, anxiolytics, or medications primarily used as mood stabilizers were excluded from the study to reduce confounding effects of such medications.

Results

A total of 2,375 patients aged 6-17 years were admitted for irritability and a diagnosis of ASD. In total 323 (13.8%) patients were readmitted from this group within 30 days of discharge. After controlling for age, sex, and gender, the use of antipsychotic medication was found to decrease 30- and 90-day readmission rates with an odds ratio of 1.2 to 1.4 times compared to no antipsychotic use (p < 0.04). In patients with autism not on antipsychotics, regression analysis revealed that older age (p = 0.0471) and White race (p = 0.0471) were associated with 30-day readmission (a = 0.05). For these patients, race was also significantly associated with 60-day (p = 0.0494) and 90-day (p = 0.0416) readmission rates. In patients with autism on either risperidone or aripiprazole, age (p = 0.0393) and race (p = 0.0316) were significantly associated with 30-day readmission rate.

Conclusions

Antipsychotic use reduced readmission rates within 30 days and 90 days in patients with irritability and ASD. Additionally, oral aripiprazole and oral risperidone were found to be equally effective in reducing the 30-day readmission rate, and neither was superior in comparison to the other in 30-, 60-, or 90-day readmission rates. The reduced 30- and 90-day readmission rates seen in our study with the use of antipsychotic medications emphasize the importance of antipsychotic use for individuals with ASD and irritability, even if the antipsychotic is not risperidone or aripiprazole. Groups who can particularly benefit from antipsychotic use include individuals who are refractory to first- and second-line therapies, such as behavioral interventions, or for those who present with persistent and serious risk of harm to themselves or others. Additionally, the use of antipsychotic medications in this scenario may reduce hospitalizations within 30 days of discharge, allowing reduction of the financial and emotional strain associated with these readmissions.

Pediatric Tuina in children with autism spectrum disorder: a study protocol for a randomized controlled trial

Background

Autism spectrum disorder (ASD) is a neurodevelopmental condition characterized by repetitive stereotypical behavior and communication deficits. Currently, it lacks a specific clinical treatment method. Pediatric Tuina is a recent therapy in traditional Chinese medicine (TCM) and has been used to treat children with ASD. Nonetheless, it remains uncommon given the lack of large-scale evidence-based medical studies. This study aims to compare the efficacy of Tuina and conventional treatment in children with ASD.

Methods

Eligible children will be randomly assigned to either the pediatric Tuina plus conventional treatment group or to the conventional treatment alone group based on a random table at a ratio of 1:1. The effectiveness of the Tuina intervention for ASD will be evaluated by a third-party organization. The pre- and post-intervention scores on the Childhood Autism Rating Scale comprised the primary outcome, whereas pre- and post-intervention scores on the Autism Treatment Evaluation Checklist were the secondary outcomes to assess improvement in symptoms. Baseline values of the participants will be determined at the time of registration. Outcomes will be evaluated after the 30th treatment session. The follow-up period will last for 6 months after treatment.

Discussion

This study will evaluate the effectiveness and safety of Tuina in the treatment of ASD. The results of this study could provide reliable evidence to improve the management of patients with ASD.

Neuroleptic Malignant Syndrome in Children with Autism Spectrum Disorder (ASD): A Case Report and Brief Review of Recent Literature

Neuroleptic malignant syndrome (NMS) is a rare, life-threatening, idiosyncratic adverse reaction to antipsychotic drugs. Despite the increasing rates in the prescription of antipsychotics in pediatric patients with autism spectrum disorder (ASD), little is known about the occurrence and hallmarks of NMS in this specific population. NMS appears to be part of the larger catatonia domain, based on the frequent relationship between ASD and catatonia, on the shared, when not overlapping, clinical features with malignant catatonia, and on the effectiveness of catatonia treatments on the NMS/MC symptoms. The intrinsic difficulties of exploring NMS in ASD in controlled studies accounts for the subsequent lack of available information. Based on recent reports and on our case report, clinical features of NMS in the pediatric ASD population appear to be the same as the non-ASD population. Further studies are needed to confirm these results.

Efficacy and safety of lurasidone in children and adolescents: Recommendations for clinical management and future research

Lurasidone is a novel azapirone derivative, and atypical antipsychotic agent with a high binding affinity for dopaminergic (D2), serotoninergic (5-HT2A), and 5-HT7 receptors (antagonist), a moderate affinity for 5-HT1A receptors (partial agonist), and no appreciable affinity for histaminergic (H1) and muscarinic (M1) receptors. It was recently included by the European Medication Agency among the in-label pharmacological treatments for children and adolescents affected by early onset schizophrenia. As a dopamine and serotonin antagonist, lurasidone acts on a variety of receptors and showed its efficacy both as an antipsychotic and an activating compound. Administered with food or within 30 minutes from a meal, it presents sufficient bioavailability and does not interact ith most of the other drugs during metabolism. With little effects on hormones and weight gain, potential procognitive profile due to its 5-HT7 antagonism, and reduced extrapyramidal side effects, lurasidone could be a good choice in terms of both effectiveness and tolerability, particularly for patients headed towards a long-term treatment. This article aims to summarize the available scientific evidence from the literature on the use of lurasidone in children and adolescents and to provide recommendations for clinical management and future research.

The progress of chemokines and chemokine receptors in autism spectrum disorders

Autism spectrum disorders (ASD) are a group of neurodevelopmental disorders and the main symptoms of ASD are impairments in social communication and abnormal behavioral patterns. Studies have shown that immune dysfunction and neuroinflammation play a key role in ASD patients and experimental models. Chemokines are groups of small proteins that regulate cell migration and mediate inflammation responses via binding to chemokine receptors. Thus, chemokines/chemokine receptors may be involved in neurodevelopmental disorders and associated with ASD. In this review, we summarize the research progress of chemokine aberrations in ASD and also review the recent progress of clinical treatment of ASD and pharmacological research related to chemokines/chemokine receptors. This review highlights the possible connection between chemokines/chemokine receptors and ASD, and provides novel potential targets for drug discovery of ASD.

The efficacy and safety in attention deficit hyperactivity disorder of second-generation antipsychotics and other medications for hyperactivity in children and adolescents with autism: a meta-analysis

Children and adolescents with ASD also have co-occurrence of attention deficit hyperactivity disorder (ADHD) symptoms. ADHD symptoms, especially hyperactivity, greatly increased the severity of autism symptoms. This study concentrated on two widely-used medications: the second generation of antipsychotics (SGAs) and ADHD medication, aiming to conduct a meta-analysis about their effect on hyperactivity, so it would offer some evidence for clinical medication choice. The Medline, Embase, Cochrane Central Register of Controlled Trials and China National Knowledge Infrastructure databases were searched from inception to July 2019 for studies exploring the use of SGAs and ADHD medications in autistic children and adolescents. Double-blind, randomized controlled trials that reported hyperactivity as an outcome were included in the study. A total of thirteen trials with 712 participants were included in our meta-analysis. For SGAs, the standardized mean difference (SMD) of hyperactivity subscale in Aberrant behavior checklist scale or conners rating scales was 0.59, 95% confidence interval (CI): 0.23-0.96, I2 = 74%, Q = 15.34, P < 0.01. For ADHD medications, SMD was -0.66, with 95% CI: -0.99 to 0.33, I2 = 53%, Q = 15.02, P = 0.04. As for adverse events, in the SGAs group, somnolence had the largest effect size, risk ratio = 5.62, 95% CI: 3.20- 9.87 (I2 = 0%, Q = 2.45, P = 0.65). In ADHD group, the side effect of decreased appetite showed the largest effect size (risk ratio = 2.63, 95% CI = 0.99-7.01, I2 = 65.7%, Q = 11.66, P = 0.02). Both ADHD medications and SGAs were effective in dealing with hyperactivity in children and adolescents with autism but were shown to increase the risk of decreased appetite, somnolence, headache and nausea or vomiting. The clinical use of these medications should carefully weigh the benefits and risks.

Understanding Chronic Aggression and Its Treatment in Children and Adolescents

PURPOSE OF REVIEW

Youth aggression is common and has a significant burden on individuals, families, and society. However, its treatment is often a challenge for clinicians. Thus, this review will examine the current understanding of youth aggression, conceptualize aggression as a symptom rather than its own disorder, and provide an overview of treatment strategies.

RECENT FINDINGS

Youth aggression is associated with complex genetic, neurobiological, and environmental risks. Prevention strategies are of the utmost importance for at-risk families and youth. Psychosocial interventions are the first line treatment. But if not fully effective, then pharmacologic interventions-including psychostimulants, alpha-2 agonists, atomoxetine, and risperidone-have shown benefits. Other medications, such as SSRIs, can be useful in certain scenarios. It is important to conceptualize youth aggression as being a trans-diagnostic symptom in psychopathology. Determining the underlying cause of aggression will help to guide treatment.

Atypical antipsychotics for Attention-Deficit/Hyperactivity disorder- science, art, or fad?

Use of atypical antipsychotics (AAPs) for attention-deficit/hyperactivity disorder (ADHD) is currently rife and trend of use is on the rise. It is largely off-label driven. Here, we touch on the topic highlighting both merits and demerits of this approach.

Use of Psychotropic Drugs among Children and Adolescents with Autism Spectrum Disorders in Denmark: A Nationwide Drug Utilization Study

Children with autism spectrum disorder (ASD) have a considerable use of psychotropics. Leveraging nationwide registry data, we aimed to describe the use of psychotropics among children and adolescents with ASD in Denmark. Use of melatonin and attention-deficit/hyperactivity disorder (ADHD) medication increased from 2010 to 2017, while there were limited changes in use of antidepressants and antipsychotics. Thirty percent of the identified children used psychotropics in 2017 most commonly ADHD medication (17%) and melatonin (13%). Methylphenidate, sertraline and risperidone were most often prescribed. Most children filled more than one prescription and, across drug classes, at least 38% received treatment two years after treatment initiation. Use of psychotropics followed psychiatric comorbidities. Comorbidities did not affect age at treatment initiation. Use of psychotropics varied according to age and sex with limited use in the youngest children. In summary, psychotropic drug use has increased in children with ASD mainly due to an increase in the use of ADHD medication and melatonin. In accordance with previous studies, use seems to follow comorbidities. The long treatment duration underlines the need to investigate long-term effects of psychotropic drug use in children with ASD.
