Background: Children and youth with attention deficit hyperactivity disorder (ADHD) may experience difficulties in participation, but few studies examine their participation and the environmental factors affecting participation. This study explored the participation and the environmental factors of children and youth, with and without attention deficit hyperactivity disorder (ADHD), in the following three settings: home, school, and community. Materials and Methods: Parents of 65 participants aged 6–14 (M = 9.91, SD = 1.87) with and without ADHD completed the Participation and Environment Measure for Children and Youth (PEM-CY) questionnaire, which evaluates participation and environmental factors, along with demographic and screening questionnaires. Results: The ADHD group (n = 31) scored significantly lower than the non-ADHD group (n = 34) in “frequency” at home, “involvement”, and overall environmental support in all settings, with parents expressing a greater desire to change their child’s home and community participation. For the ADHD group, a relationship was found between environmental support and involvement in all three settings. Conclusions: The findings demonstrated differences in the participation of children and youth with ADHD across different settings, compared to those without ADHD, and confirmed the effect of environmental factors on participation, especially involvement. It is essential to consider participation measures and environmental factors when designing interventions for children and youth with ADHD.

AbstractAttention-deficit/hyperactivity disorder (ADHD) is one of the most common neurodevelopmental disorders in children. Although the mechanisms that lead to the development of ADHD remain unclear, genetic and environmental factors have been implicated. These include heavy metals and chemical exposures, nutritional and lifestyle/psychosocial factors. The aim of this review was to investigate the association between ADHD or ADHD-related symptoms and widespread environmental factors such as phthalates, bisphenol A (BPA), tobacco smoke, polycyclic aromatic hydrocarbons (PAHs), polyfluoroalkyl chemicals (PFCs) and alcohol. Medline, PubMed and Ebsco search was performed to identify the studies which analyze the association of prenatal and postnatal child exposure to environmental toxicants and lifestyle factors and ADHD or ADHD-related symptoms. The review is restricted to human studies published since 2000 in English in peer reviewed journals. Despite much research has been done on the association between environmental risk factors and ADHD or ADHD symptoms, results are not consistent. Most studies in this field, focused on exposure to tobacco smoke, found an association between that exposure and ADHD and ADHD symptoms. On the other hand, the impact of phthalates, BPA, PFCs, PAHs and alcohol is less frequently investigated and does not allow a firm conclusion regarding the association with the outcomes of interest.

Adhd Rating Scales

Malingering is a significant assessment concern in adults undergoing evaluations for attention deficit/hyperactivity disorder (ADHD) and may occur for a number of reasons, including access to medication and/or accommodations. Therefore, it is important to investigate ways to determine accuracy of self-reported ADHD symptoms. The present study used a simulation design to examine the impact of reasons for malingering on the Conners’ Adult ADHD Rating Scales (CAARS) Symptom subscales and the CAARS infrequency index (CII). Participants ( N = 157) were randomly assigned to one of three conditions: best effort, malingering for stimulant medication, or malingering for extra time accommodations. The three groups were compared with 34 individuals reporting previous diagnosis of ADHD. Results showed that individuals in both malingering groups scored higher than controls on all CAARS subscales and CII. Individuals in the medication malingering group, but not the extra time malingering group, scored higher than the ADHD group on CII and several CAARS subscales whose content overtly reflects ADHD symptomatology. Findings emphasize the influence of malingering on self-reported ADHD symptoms and the need to assess for malingering in ADHD evaluation. Results also suggest that reason for malingering might differentially affect self-report of ADHD symptoms.

During one year (september 2013 � september 2014), 50 children from the residential institution for children SOS Satele Copiilor Bucharest, where included in our research. The children were distributed in two groups: Group A which consisted of 25 children (12 girls, 13 boys) who were not diagnosed with attention deficit hyperactivity disorder (ADHD) and Group B which consisted of 25 children (14 boys, 11 girls) who were diagnosed with ADHD. Initially, the two groups were subjected at a psycho-diagnostic battery of tests, one of them being the Evaluating the Health State of children with ADHD questionnaire elaborated by us, particularly for this research, with the purpose of highlighting the direct link between the children health state and their ADHD symptoms. This study sought to determine the concentration of copper in urine samples from a group of children with ADHD and a group of normal children, to highlight the role of copper in the development of ADHD symptoms. Levels of copper concentration in urine samples from the two groups were processed by Student�s t-Test. Statistical analysis showed that the arithmetic averages of copper concentration in urine samples, of the two groups do not differ significantly, so copper may be causing ADHD symptoms occur. The copper content in urine samples has been determined using atomic absorption spectrometry with graphite furnace.

AbstractAttention-deficit hyperactivity disorder (ADHD) is a neurological and neurodevelopmental childhood-onset disorder characterized by a persistent pattern of inattentiveness, impulsiveness, restlessness, and hyperactivity. These symptoms may continue in 55–66% of cases from childhood into adulthood. Even though the precise etiology of ADHD is not fully understood, it is considered as a multifactorial and heterogeneous disorder with several contributing factors such as heritability, auxiliary to neurodevelopmental issues, severe brain injuries, neuroinflammation, consanguineous marriages, premature birth, and exposure to environmental toxins. Neuroimaging and neurodevelopmental assessments may help to explore the possible role of genetic variations on ADHD neuropsychobiology. Multiple genetic studies have observed a strong genetic association with various aspects of neuropsychobiological functions, including neural abnormalities and delayed neurodevelopment in ADHD. The advancement in neuroimaging and molecular genomics offers the opportunity to analyze the impact of genetic variations alongside its dysregulated pathways on structural and functional derived brain imaging phenotypes in various neurological and psychiatric disorders, including ADHD. Recently, neuroimaging genomic studies observed a significant association of brain imaging phenotypes with genetic susceptibility in ADHD. Integrating the neuroimaging-derived phenotypes with genomics deciphers various neurobiological pathways that can be leveraged for the development of novel clinical biomarkers, new treatment modalities as well as therapeutic interventions for ADHD patients. In this review, we discuss the neurobiology of ADHD with particular emphasis on structural and functional changes in the ADHD brain and their interactions with complex genomic variations utilizing imaging genetics methodologies. We also highlight the genetic variants supposedly allied with the development of ADHD and how these, in turn, may affect the brain circuit function and related behaviors. In addition to reviewing imaging genetic studies, we also examine the need for complementary approaches at various levels of biological complexity and emphasize the importance of combining and integrating results to explore biological pathways involved in ADHD disorder. These approaches include animal models, computational biology, bioinformatics analyses, and multimodal imaging genetics studies.

BackgroundThe impact of longitudinal psychiatric comorbidity, parenting and social characteristics on attention-deficit hyperactivity disorder (ADHD) medication use is still poorly understood.AimsTo assess the baseline and longitudinal influences of behavioural and environmental factors on ADHD medication use.MethodSurvival regressions with time-dependent covariates were used to model data from a population-based longitudinal birth cohort. The sample (n = 1920) was assessed from age 5 months to 10 years. Measures of children's psychiatric symptoms, parenting practices and social characteristics available at baseline and during follow-up were used to identify individual and family-level features associated with subsequent use of ADHD medication.ResultsUse of ADHD medication ranged from 0.2 to 8.6% between ages 3.5 to 10 years. Hyperactivity–inattention was the strongest predictor of medication use (hazard ratio (HR) = 2.75, 95% CI 2.35–3.22). Among all social variables examined, low maternal education increased the likelihood of medication use (HR = 2.09, 95% CI 1.38–3.18) whereas immigrant status lowered this likelihood (HR = 0.40, 95% CI 0.17–0.92).ConclusionsBeyond ADHD symptoms, the likelihood of receiving ADHD medication is predicted by social variables and not by psychiatric comorbidity or by parenting. This emphasises the need to improve global interventions by offering the same therapeutic opportunities (including medication) as those received by the rest of the population to some subgroups (i.e. immigrants) and by diminishing possible unnecessary prescriptions.

Neuropsychological Tasks

The literature on the neuropsychology of Attention Deficit Hyperactivity Disorder (ADHD) is plagued by inconsistent findings, which are usually attributed to a variety of extraneous variables. One of the most inadequately explored of these variables is the difference between ADHD children attending remedial and mainstream schools. This study aimed to investigate whether the performance of remedial and mainstream school ADHD boys differs on relevant neuropsychological tasks. The sample consisted of three groups of 8- to 12-year-old boys. Two of these groups consisted of children with ADHD: one from remedial schools and one from mainstream schools. The third group was made up of participants without ADHD, who attended mainstream schools. The performance of the remedial school learners on the Stroop, Lurian and cancellation tasks was investigated and compared to a mainstream school ADHD sample. The performance of the ADHD group as a whole was compared with that of a control group. No significant difference in performance was found between the two ADHD groups, except for the length of time taken to read words in the control condition of the Stroop. The control group out-performed the ADHD samples on the Stroop, Lurian and cancellation tasks. The findings suggest that mainstream and remedial ADHD boys do not differ in the severity of their executive deficits, but that boys with ADHD attending remedial schools may be more likely to have another learning disorder than their counterparts at mainstream schools.

Given that children with attention deficit hyperactivity disorder (ADHD) are more impulsive than peers, this study explored whether they are correspondingly more creative, and whether creativity declines when impulsivity is decreased through methylphenidate (Ritalin) therapy. A repeated-measures quasi-experimental design was used to compare the performance of 19 boys with previously diagnosed ADHD and 21 comparison boys aged 8 through 11 on two administrations of alternate forms of the Torrance Tests of Creative Thinking-Figural (nonverbal). Boys with ADHD received prescribed methylphenidate only for the first session. Overall, mean Torrance summary scores for comparison boys (mean = 115.1, SD = 16.1) were higher than for boys with ADHD (mean = 107.6, SD = 12.7). However, the difference between means was small (7%) and did not meet the 25% criterion for a clinically significant difference. No changes in performance over time (comparison group) or medication state (ADHD group) were observed. These data suggest that, when measured nonverbally, the creative thinking performance of boys with ADHD is not superior to that of peers who do not have ADHD. Regarding the effects of methylphenidate, prescribed therapy did not influence performance on this measure of creative thinking.

ObjectivePrevious studies have indicated that there is dopamine transporter (DAT) dysregulation and P300 abnormality in adults with attention-deficit hyperactivity disorder (ADHD); however, the correlations among the three have not been fully explored.MethodsA total of 11 adults (9 males and 2 females) with ADHD and 11 age-, sex-, and education-level-matched controls were recruited. We explored differences in DAT availability using single-photon emission computed tomography and P300 wave of event-related potentials between the two groups. The correlation between DAT availability and P300 performance was also examined.ResultsDAT availability in the basal ganglia, caudate nucleus, and putamen was significantly lower in the ADHD group. Adults with ADHD had lower auditory P300 amplitudes at the Pz and Cz sites, as well as longer Fz latency than controls. DAT availability was negatively correlated to P300 latency at Pz and Fz.ConclusionsAdults with ADHD had both abnormal DAT availability and P300 amplitude, suggesting that ADHD is linked to dysfunction of the central dopaminergic system and poor cognitive processes related to response selection and execution.
