Sleep disorders in children with attention-deficit/hyperactivity disorder

Background Attention-deficit/hyperactivity disorder (ADHD) is a neurobehavioral abnormality that commonly occurs among children. Sleep disorders are comorbid with ADHD. Sleep disorders in Indonesian children with ADHD have not been widely studied.Objective To understand the proportion and factors that influence sleep disorders in children with ADHD. Methods This cross-sectional study involved 54 children aged 3-14 years who had been diagnosed with ADHD by a pediatric growth and development consultant using DSM-5 criteria. The subjects were consecutively selected from March to August 2017 at the Child Development Polyclinic, Dr. Sardjito Hospital, Yogyakarta. Sleep data were collected using the Sleep Disturbances Scale for Children (SDSC) and the Children’s Sleep Hygiene Scale (CSHS).Results Of the 54 children with ADHD (46 males and 8 females), 35 (64.8%) experienced sleep disorders. The majority (26 subjects, 48.1%) had the disorder of initiating and maintaining sleep. Children with the combined (inattention and hyperactive-impulsive) type of ADHD experienced significantly greater sleep disturbance compared to the inattention type or hyperactive-impulsive type (OR=3.750; 95% CI 1.133 to 12.41; P=0.027). Poor sleep hygiene was also significantly associated with more severe sleep disorders (r=-0.383, P=0.004).Conclusion The proportion of sleep disorder in children with ADHD is relatively high, with the majority having a disorder of initiating and maintaining sleep. Children with combined type ADHD experience a higher amount of sleep disorder than those with either the inattention or hyperactive-impulsive types of ADHD. Children with poor sleep hygiene have significantly more severe sleep disorders.

Moderating Effect of Motor Proficiency on the Relationship Between ADHD Symptoms and Sleep Problems in Children With Attention Deficit Hyperactivity Disorder–Combined Type

ABSTRACTObjectives/Background: A high proportion of children with Attention Deficit Hyperactivity Disorder- Combined type (ADHD-CT) experience sleep and motor problems. This study investigated (a) whether motor proficiency moderated the relationship between ADHD symptoms and sleep problems in children with and without ADHD-CT and (b) whether this moderation differed as a function of ADHD diagnosis.Participants: A sample of 70 primary school male children between 8–15 years were recruited; children with ADHD-CT (n = 38; mean age 10 years, 2 months [SD = 1 year, 6 months]) and a typically developing (TD) (n = 32; mean age 9 years, 6 months [SD = 1 year, 5 months]) group.Methods: Motor proficiency was measured using the Movement Assessment Battery for Children-2nd Edition (MABC-2), ADHD symptoms were measured using the Conners’ Parent Rating Scale (CPRS) and parent reported sleep problems were measured using the Children’s Sleep Habits Questionnaire (CSHQ).Results: Children who reported higher ADHD symptoms and lower motor proficiency scores reported more sleep problems. The moderation effect only held in children with a diagnosis of ADHD-CT and not in the typically developing group.Conclusions: These findings indicate that children who experience greater severity of ADHD symptoms who also have lower motor proficiency may be at increased risk of experiencing sleep problems. These findings also illustrate the importance of considering motor proficiency when exploring risk factors for sleep problems in children with ADHD-CT as well as sleep interventions.

Salivary cortisol and alpha-amylase diurnal profiles and stress reactivity in children with Attention Deficit Hyperactivity Disorder

There is growing evidence for dysregulation of the stress system in individuals with Attention Deficit Hyperactivity Disorder (ADHD). The stress system includes neuroanatomical and functional components that function in concert to maintain homeostasis and its main effectors are the hypothalamic-pituitary-adrenal (HPA) axis and the sympathetic/adrenomedullary nervous system (SNS). As stress system activity demonstrates a distinct circadian variation, we aimed to describe simultaneously, diurnal rhythms of both the HPA axis and the SNS in children with ADHD and a comparison group. Moreover, we attempted to investigate stress responses to a physical stressor, venipuncture, in both groups. Sixty-two prepubertal children with ADHD combined (ADHD-C) or inattentive (ADHD-I) type and 40 typically developing children provided saliva samples at six specific time points during a day, as well as before and 10 min after a scheduled morning venipuncture. Salivary cortisol and α- amylase were selected as reliable noninvasive biomarkers for HPA axis and SNS function and were measured in the samples obtained. Results revealed that children with ADHD-C had lower mean cortisol values both 30 min after awakening and at 18:00 h than controls (p = 0.002 and p = 0.018 respectively), as well as lower mean Cortisol Awakening Response (CAR) and Area Under the Curve for “wake to bed” period (AUCi) values of cortisol (p = 0.004 and p = 0.001, respectively). Also, mean CAR and cortisol AUCi were lower in children with ADHD-I than the control group (p = 0.034 and p = 0.038 respectively). Alpha-amylase measurements showed an increase over time (p < 0.001), which was similar in all three groups. Interestingly, α-amylase changes over time were correlated with the corresponding cortisol changes (p < 0.001). Venipuncture, elicited a significant increase only in α-amylase levels and more so in the control group (p = 0.003). These findings suggest a partial hypofunction of the stress system in children with ADHD.

Delay aversion in attention deficit/hyperactivity disorder is mediated by amygdala and prefrontal cortex hyper-activation.

Experimental research supports delay aversion as a motivational feature of attention deficit/hyperactivity disorder (ADHD). To investigate the neurobiology of delay aversion in ADHD, this study examined whether adolescents with ADHD display an unusually strong activation in affective brain regions in response to cues predicting forthcoming delay and whether these effects are (a) delay-dose dependent and (b) statistically mediate the association between ADHD and self-reported delay aversion. Twenty-nine right-handed male adolescents with combined type ADHD and 32 typically developing controls (ages 10-18years) performed a reaction time task in an MRI scanner. Pretarget cues indicated delay-related response consequences. One indicated that delay would follow the response irrespective of response speed (CERTAIN DELAY), a second that delay would only follow if the response was too slow (CONDITIONAL DELAY), and a third that no delay would follow the response whatever its speed (NO DELAY). Delay levels were 2, 6, or 14s. Participants also rated their own delay aversion in everyday life. Individuals with ADHD rated themselves as more delay averse than controls. Significantly greater activation to CERTAIN DELAY cues relative to NO DELAY cues was found in participants with ADHD compared to controls (bilaterally) in amygdala, anterior insula, temporal pole, dorsolateral prefrontal cortex (DLPFC), and ventromedial prefrontal cortex. Amygdala and DLPFC activation strength were strongly and delay-dose dependently correlated with delay aversion ratings, and statistically mediated the relationship between ADHD status and delay aversion. When presented with cues predicting impending delay, adolescents with ADHD, relative to controls, displayed a delay-related increase in activation in amygdala and DLPFC, regions known to be implicated in the processing of aversive events. Future studies should examine the specificity of these effects to delay aversion compared to aversive events in general.

Substance use through adolescence into early adulthood after childhood-diagnosed ADHD: findings from the MTA longitudinal study.

Inconsistent findings exist regarding long-term substance use (SU) risk for children diagnosed with attention-deficit/hyperactivity disorder (ADHD). The observational follow-up of the Multimodal Treatment Study of Children with ADHD (MTA) provides an opportunity to assess long-term outcomes in a large, diverse sample. Five hundred forty-seven children, mean age 8.5, diagnosed with DSM-IV combined-type ADHD and 258 classmates without ADHD (local normative comparison group; LNCG) completed the Substance Use Questionnaire up to eight times from mean age 10 to mean age 25. In adulthood, weekly marijuana use (32.8% ADHD vs. 21.3% LNCG) and daily cigarette smoking (35.9% vs. 17.5%) were more prevalent in the ADHD group than the LNCG. The cumulative record also revealed more early substance users in adolescence for ADHD (57.9%) than LNCG (41.9%), including younger first use of alcohol, cigarettes, marijuana, and illicit drugs. Alcohol and nonmarijuana illicit drug use escalated slightly faster in the ADHD group in early adolescence. Early SU predicted quicker SU escalation and more SU in adulthood for both groups. Frequent SU for young adults with childhood ADHD is accompanied by greater initial exposure at a young age and slightly faster progression. Early SU prevention and screening is critical before escalation to intractable levels.

Pathway to care and clinical profile of children with attention-deficit hyperactivity disorder in New Delhi, India.

BACKGROUND:Attention-deficit hyperactivity disorder (ADHD) is a common childhood neurobehavioral disorder, which may cause impairment in multiple domains. Understanding the pathway to care helps in planning effective early interventions. The study aims to provide a quantitative description of the factors affecting the help-seeking pathway.MATERIALS AND METHODS:The study was conducted at an outpatients department of a tertiary care multispecialty hospital. Fifty consecutive consenting children aged 5–15 years were screened and diagnosed for ADHD using Conners' Parent Rating Scale-Revised: Short Form, Diagnostic and Statistical Manual of Mental Disorders fourth edition text revision criteria, and Kiddie Schedule for affective disorders and schizophrenia. A semi-structured questionnaire was used to study the pathway of care, using the WHO template. The data were analyzed using appropriate parametric and nonparametric tests in SPSS software.RESULTS:The average delay from the onset of the illness to first consultation with a qualified health professional was 2.32 ± 1.9 years. Children with an urban background, from a nuclear family, with literate mothers, with a family income of more than Rs. 30,000/month, having hyperactive and combined type of ADHD, and who were referred by school teachers presented significantly earlier. The main source of referrals were school teachers and general medical practitioners. The most common parental beliefs for delay were the views that the “child is naughty” and that “hyperactivity is part of normal growth.”CONCLUSION:Parents' help-seeking behavior is affected by different sociocultural beliefs. Such factors as the lack of recognition and awareness of ADHD, resulting in the delay in seeking treatment should be addressed through health promotion programs.

Designing an interactive learning application for ADHD children

This research focused on ADHD children with problems such as lack of attention, hyperactive, and impulsive that affect their school academic skills. Educational disturbances found in children with ADHD at Elementary School are low interest in learning, weak memorizing, unenthusiastic with large text and lack of concentration. They have less interest in Social Science Subjects. There are some learning applications developed to help children learn social science. However, there is none focused on ADHD children. Thus, a study was conducted to determine the user interface model of interactive learning application of social science subjects in accordance with user experience in ADHD children by implementing the Children-Centered Design method. Then we analyzed the application usability level measured using USE Questionnaire. The usability testing of the prototype has resulted in average usability of 90.05%, this shows the category of application is very good and can be used for children ADHD.

SLC6A3 polymorphism and response to methylphenidate in children with ADHD: A systematic review and meta-analysis.

Methylphenidate (MPH) is the most commonly used treatment for attention-deficit hyperactivity disorder (ADHD) in children. However, the response to MPH is not similar in all patients. This meta-analysis investigated the potential role of SLC6A3 polymorphisms in response to MPH in children with ADHD. Clinical trials or naturalistic studies were selected from electronic databases. A meta-analysis was conducted using a random-effects model. Cohen's d effect size and 95% confidence intervals (CIs) were determined. Sensitivity analysis and meta-regression were performed. Q-statistic and Egger's tests were conducted to evaluate heterogeneity and publication bias, respectively. The Grading of Recommendations Assessment, Development and Evaluation (GRADE) system was used to assess the quality of evidence. Sixteen studies with follow-up periods of 1-28 weeks were eligible. The mean treatment acceptability of MPH was 97.2%. In contrast to clinical trials, the meta-analysis of naturalistic studies indicated that children without 10/10 repeat carriers had better response to MPH (Cohen's d: -0.09 and 0.44, respectively). The 9/9 repeat polymorphism had no effect on the response rate (Cohen's d: -0.43). In the meta-regression, a significant association was observed between baseline severity of ADHD, MPH dosage, and combined type of ADHD in some genetic models. Sensitivity analysis indicated the robustness of our findings. No publication bias was observed in our meta-analysis. The GRADE evaluations revealed very low levels of confidence for each outcome of response to MPH. The results of clinical trials and naturalistic studies regarding the effect size between different polymorphisms of SLC6A3 were contradictory. Therefore, further research is recommended.

Comparative Analysis of the WISC between Two ADHD Subgroups.

ObjectiveThe prevalence of attention deficit/hyperactivity disorder (ADHD) in school-age children is 7.2%, and ADHD is divided into clinical subtypes. MethodsThe current study explored whether specific cognitive profiles as assessed using the Wechsler Intelligence Scale for Children (WISC)-IV could be obtained for each clinical ADHD subtype (ADHD-Inattentive type and ADHD-Combined type) and investigated the correlation between WISC scores and parental age at their children’s birth or birthweight. The enrolled sample comprised 12 ADHD-I and 15 ADHD-C subjects. ResultsAn impaired Processing Speed Index was found in ADHD-I. The age of the father at the child’s birth and birthweight positively correlated with the full scale intelligence quotient (FSIQ) score in the WISC assessment. ConclusionInattentiveness within the behaviors of the children with ADHD-I is partly due to the impaired processing speed, therefore effective support for ADHD will be conducted if educator decreases their speaking speed. Since biological basis of ADHD is still largely unknown, future studies using both psychological and biological methods will reveal the etiology of ADHD. These scientific assessments will provide information for more effective approaches in the care of children with ADHD.

Anxiety and depression among college students with attention-deficit/hyperactivity disorder (ADHD): Cross-informant, sex, and subtype differences

ABSTRACTObjective: This study examined symptoms of anxiety and depression among college students with attention-deficit/hyperactivity disorder (ADHD). Participants: Data were collected between March 2011 and March 2016 from 150 college students with ADHD and 150 college students without ADHD. Method: Participants with ADHD were compared to a sex- and ethnicity-matched control group. For the ADHD group, parent and self-report of anxiety and depression were also compared. Results: College students with ADHD self-reported significantly higher anxiety and depressive symptoms than did students without ADHD. Scores on parent-report measures of anxiety and depressive symptoms were significantly higher than scores on self-report measures. Significant sex differences were found for participants with ADHD, with females showing higher depressive and anxiety symptoms than males. Parent-reported anxiety symptoms were higher for those with inattentive type ADHD compared to combined type ADHD. Conclusion: The current study highlights the importance of multi-informant assessment in ADHD evaluations for college-aged adults.

Investigation of attention deficit hyperactivity disorder (ADHD) sub-types in children via EEG frequency domain analysis

ABSTRACTAim of the study: To investigate the frequency domain effects and changes in electroencephalography (EEG) signals in children diagnosed with attention deficit hyperactivity disorder (ADHD).Patients and methods: The study contains 40 children. All children were between the ages of 7 and 12 years. Participants were classified into four groups which were ADHD (n=20), ADHD-I (ADHD-Inattentive type) (n=10), ADHD-C (ADHD-Combined type) (n=10), and control (n=20) groups. In this study, the frequency domain of EEG signals for ADHD, subtypes and control groups were analyzed and compared using Matlab software. The mean age of the ADHD children's group was 8.7 years and the control group 9.1 years.Results: Spectral analysis of mean power (μV2) and relative-mean power (%) was carried out for four different frequency bands: delta (0--4 Hz), theta (4--8 Hz), alpha (8--13 Hz) and beta (13--32 Hz). The ADHD and subtypes of ADHD-I, and ADHD-C groups had higher average power value of delta and theta band than that of control group. However, this is not the case for alpha and beta bands. Increases in delta/beta ratio and statistical significance were found only between ADHD-I and control group, and in delta/beta, theta/delta ratio statistical significance values were found to exist between ADHD-C and control group.Conclusion: EEG analyzes can be used as an alternative method when ADHD subgroups are identified.

An event-related potential investigation of the acute effects of aerobic and coordinative exercise on inhibitory control in children with ADHD

The current body of evidence suggests that an aerobic exercise session has a beneficial effect on inhibitory control, whereas the impact of coordinative exercise on this executive function has not yet been examined in children with ADHD. Therefore, the present study aims to investigate the acute effects of aerobic and coordinative exercise on behavioral performance and the allocation of attentional resources in an inhibitory control task.Using a cross-over design, children with ADHD-combined type and healthy comparisons completed a Flanker task before and after 20 min moderately-intense cycling exercise, coordinative exercise and an inactive control condition. During the task, stimulus-locked event-related potentials were recorded with electroencephalography.Both groups showed an increase of P300 amplitude and decrease of reaction time after exercise compared to the control condition. Investigating the effect of exercise modality, aerobic exercise led to greater increases of P300 amplitude and reductions in reaction time than coordinative exercise in children with ADHD.The findings suggest that a single exercise bout improves inhibitory control and the allocation of attentional resources. There were some indications that an aerobic exercise session seems to be more efficient than coordinative exercise in reducing the inhibitory control deficits that persist in children with ADHD.

Parenting practices of Singaporean mothers of children with ADHD

Objectives: We wanted to determine: (1) whether ADHD symptoms were more common in mothers of children with ADHD; (2) whether mothers of children with ADHD differed in their parenting strategies; and (3) whether there was a difference in care-giving arrangements for children with ADHD and without ADHD. This was done by comparing mothers of children with ADHD with mothers of children without ADHD in Singapore. Methods: Mothers of children with ADHD ( n=46) and mothers of children without ADHD ( n=45) completed the Conners’ Parent Rating Scale-Revised, the Conners’ Adult ADHD Rating Scale-Self Report and the Alabama Parenting Questionnaire. Results: Mothers of children with ADHD did not report higher levels of current ADHD symptoms compared with the control group. However, they did use less adaptive parenting strategies. There were also no differences in the reported behaviours of children cared for by a paid worker and those cared for by mothers. Conclusions: Data support the Singapore Clinical Guidelines recommendations for the promotion of parenting skills, and referral to parenting programmes for parents of children with ADHD. The promotion of parenting skills and referral to parenting programmes for mothers of children with ADHD might include the option of electronic forms of programme delivery. The model of using paid help in the home, which is commonplace in Singapore, does not seem to disadvantage children with ADHD.

Quality of life in parents of children with attention-deficit-hyperactivity disorder

AimThe aim of our study was to investigate and compare the quality of life of parents of children with ADHD and parents of children within psychiatric troubles.MethodsWe conducted a cross sectional and comparative study, on 20 families of children with ADHD, followed in child and adolescent psychiatry department of Sfax, Tunisia, and 20 control families. We used the Short Form Health Survey (SF 36) translated and validated in Arabic to evaluate the quality of life of the parents of the two groups.ResultsThe average age of the patients of our survey was 9 years 8 months with a predominance of boys. We objectified a significant difference between the overall scores of the quality of life of parents of children with ADHD and the control sample. A highly significant difference was noted in the following areas: mental health, bodily pain and social functioning. The difference was significant in vitality score. The difference was not significant in 4 scores: general health, physical functioning, role physical, and role emotional.ConclusionFamilies with a child with ADHD have many challenges which impact certainly in their quality of life. As a child and adolescent's psychiatrics, we should be aware of these consequences in order to help the parents to improve their quality of life.Disclosure of interestThe authors have not supplied their declaration of competing interest.

The Impact of Pharmacotherapy on Substance Use in Adolescents With Attention-Deficit/Hyperactivity Disorder: Variations Across Subtypes

ABSTRACTObjective: The primary purpose of this study was to investigate the impact of attention-deficit/hyperactivity disorder (ADHD) pharmacotherapy on the risk of substance use within each ADHD subtype. Methods: The study used data from the National Comorbidity Survey-Adolescent supplement, a nationally representative sample of US adolescents (ages 13–18) collected from 6,483 adolescent-parent interviews conducted between 2001 and 2004. ADHD was categorized into three subtypes: ADHD-predominantly hyperactive-impulsive type (ADHD-H); ADHD-predominantly inattentive type (ADHD-I); and ADHD-combined type (ADHD-C) using Diagnostic and Statistical Manual of Mental Disorders-IV criteria. Substance use information was obtained from the adolescents’ interview. The impact of ADHD-pharmacotherapy on substance use was examined using multivariable logistic regression analysis. Results: Among the adolescents with ADHD, ADHD pharmacotherapy significantly associated with reduced risk of substance use (OR = 0.53, 95%CI [0.31–0.90]); with regards to ADHD subtypes, ADHD pharmacotherapy is negatively associated with substance use in adolescents with ADHD-C (OR = 0.53, 95%CI [0.24–0.97]) and those with ADHD-H (OR = 0.23, 95% CI [0.07–0.78]), but it did not have statistically significant effect on risk of substance use in those with ADHD-I subtype (OR = 0.49, 95%CI [0.17–1.39]). Among the group who never received ADHD-pharmacotherapy before the interview, individuals with ADHD-H and ADHD-C had a similar risk of substance use compared to adolescents with ADHD-I (ADHD-C: OR = 1.5, 95%CI [0.77–2.95] and ADHD-H: OR = 2.10, 95%CI [0.87–4.95]). Conclusions: Adolescents with ADHD were equally susceptible to future substance use disregard their ADHD subtypes. Receipt of pharmacotherapy could decrease risk of substance use in adolescents with ADHD-H and ADHD-C, but it may not affect risk of substance use among individuals with ADHD-I.

Bifactor Models of Attention Deficit/Hyperactivity Symptomatology in Adolescents: Criterion Validity and Implications for Clinical Practice.

This study evaluated the fit and criterion validity of a bifactor model for 18 DSM-IV attention deficit/hyperactivity disorder (ADHD) symptoms, along with nine supplementary symptoms that represented the manifestation of inattention and hyperactivity-impulsivity in adolescence and early adulthood. Participants included N = 172 adolescents who were diagnosed with combined type ADHD and who were enrolled in a treatment study. A bifactor model provided reasonably good fit to combined parent- and teacher-reported DSM symptoms and supplemental items at baseline prior to treatment. Across models, the general factor was characterized by high reliability (ω = .93, .95), while specific inattentive and hyperactive-impulsive factors were characterized by poor reliability (ω = .30-.50). With respect to criterion validity, the general ADHD and specific inattentive factors were uniquely associated with home and school impairment (R2 = .13-.29) but not adolescent risk-tasking behavior. Results are discussed with respect to the ways in which bifactor models of ADHD inform the diagnostic criteria for ADHD.

Structural and Functional Abnormalities in Children with Attention-Deficit/Hyperactivity Disorder: A Focus on Subgenual Anterior Cingulate Cortex.

Attention-deficit/hyperactivity disorder (ADHD), characterized by developmentally inappropriate inattention, hyperactivity/impulsivity, or a combination of both, is a major public health problem. Neuroimaging studies have revealed associations of these cognitive impairments with structural and functional deficits all over the brain. Existing findings are not fully consistent because of the heterogeneity of study samples and diversity of research techniques. In this study, we propose to utilize a multimodal magnetic resonance imaging (MRI) approach to study the structural and functional brain networks in children with ADHD-combined type (ADHD-C) with a focus on the subgenual anterior cingulate cortex (sgACC). Diffusion tensor imaging (DTI) and resting-state functional MRI (rs-fMRI) data from 32 children with ADHD-C and 32 group-matched controls were involved. Network-based statistic analysis of the rs-fMRI data revealed a disconnected functional network between the sgACC and multiple regions in the occipital lobe and cerebellum, whereas the DTI data showed disrupted white matter integrity in the subgenual cingulum bundle (sgCB). Post hoc region of interest (ROI)-based analyses showed significantly increased fluctuation of the spontaneous brain activity in the sgACC and higher radial diffusivity in the sgCB in the ADHD group. Both the rs-fMRI and DTI ROI-based measures were significantly correlated with clinical measures that examine behavioral capacities of attention and inhibitory control. Findings of this study suggest that functional alterations in the sgACC and white matter under development in the sgCB may impact each other, and together contribute to impaired attention and inhibitory control function in children with ADHD.

Bullying and ADHD: Which Came First and Does it Matter?

CASE: Aiden, a 13-year-old boy in the sixth grade who is relatively new to your practice, is seen for follow-up after his routine physical last month when you noted concerns for possible attention-deficit hyperactivity disorder (ADHD) and gave the family Vanderbilt Scales to complete. Aiden has a family history of ADHD, specific learning disabilities, and mood disorder. His mother reports that she is concerned about how Aiden is doing at school; his teachers are complaining that he is not doing his work, and she is worried that he may be kept back in school. Aiden first began having trouble in the third grade. He was retained in the fourth grade for academic and behavioral reasons. Now his mother has been receiving calls about him not paying attention, distracting others, and staring at his paper. At home, he does not want to do homework and gets very frustrated. In fifth grade, he had a psychoeducational evaluation and was found not eligible for services. His achievement testing showed average scores in reading, math, and writing. Cognitive testing demonstrated average scores for verbal and nonverbal abilities and memory but was significantly below average for processing speed. Aiden continues to have problems now in into the sixth grade. You speak with Aiden in the office and ask him about school. He says, “It's bad. I'm failing.” He believes his major problems at school are that he is not doing his homework, he easily becomes frustrated, and he argues with the teachers. He has supportive relationships with his family and friends at school. He gets along well with some of his teachers, noting that he loves his science teacher even though she is tough and “gives hard homework.” He describes his history teacher as “annoying.” When you ask what he means he states this teacher “Can be not nice and says mean things. She picks on me a lot.” His description is consistent with the use of shaming as a behavior he experiences at school. You review the completed parent and teacher Vanderbilt forms; both are consistent and concerning for combined type ADHD. You discuss the diagnosis of ADHD with his mother and both agree to revisit pharmacotherapy in September when the school year resumes. You give her resources on ADHD and classroom accommodations and discuss requesting a 504 plan at school. You also discuss behavioral therapy to better address his self-regulation skills. A week later, you receive a telephone call from Aiden's mother. “Aiden got home today and he is more upset than I have ever seen him! His teacher told him in front of the class that he would probably stay back a year and now he is saying there is no point in going to school.” She is not aware if retention has been recommended for Aiden. What would you say to Aiden's mother? What would you do next?

Hallusinosis due to methylphenidate overdose in an eight-year-old child: a case report

Methylphenidate, which blocks the presynaptic norepinephrine and dopamine transporters, is the most common used medication and offered as first choice in the treatment guidelines of attention deficit hyperactivity disorder (ADHD). One of its rarely seen adverse effects is, hallucinations that can be formed idiosyncratically, which can be correlated with increased dopaminergic functioning in synaptic cleft. We will present an eight year old boy diagnosed with ADHD-combined type, and oppositional defiant disorder (ODD) with no previous medical and family history who has impulsively taken extra dose of methylphenidate in the course of usual drug treatment. The acute hallucinosis presentation which has subsided the next day completely with the cessation of drug treatment will be discussed. Keywords: Methylphenidate, Hallucinosis, Attention deficit hyperactive disorder
