Traits of attention deficit/hyperactivity disorder in school-age children who stutter

PurposeThe purpose of this study was to explore whether parents of CWS reported the presence of ADHD symptoms that would warrant a referral to a psychologist to rule out the disorder. This study also aimed to describe the characteristics of the sample in terms of gender, family history of stuttering, presence of neurological impairment, concomitant diagnoses, and stuttering severity. Finally, this study sought to explore the possible statistical relations among these same variables. MethodsParticipants were 36 school-age CWS (32 males and 4 females) between the ages of 3.9 and 17.2 years (M=10.4, SD=4.0). Parent responses on the ADHD Rating Scale (Power et al., 2001) were collected via a retrospective chart review. ResultsFor this sample 58% (n=21), of the participants met criteria for needing referral for additional evaluation for symptoms related to ADHD. A strong positive relation (r=.720, p<.001) was found between a reported family history of recovered stuttering and the presence of a concomitant diagnosis. ConclusionThe results of the present study demonstrate the need for further training and education for SLPs working with CWS regarding ADHD.Educational objectives: The reader will be able to (1) describe the main characteristics of ADHD, (2) discuss the evidence suggesting a possible relationship between ADHD and stuttering and (3) discuss how ADHD characteristics could impact clinical outcomes for CWS.

Does age of onset of impairment impact on neuropsychological and personality features of adult ADHD?

The consideration of age of onset of impairment as part of the ADHD diagnosis is controversial and has been a revisited issue with the emergence of the new classifications in Psychiatry. The aim of this study is to compare patients with early and late onset of ADHD impairment in terms of neuropsychological and personality characteristics. Adult patients with ADHD (n = 415) were evaluated in the ADHD outpatient program at Hospital de Clínicas de Porto Alegre, Brazil. The diagnostic process for ADHD and comorbidities was based on DSM-IV criteria. The comparison between the two ages of onset groups (before 7; n = 209 or from 7 to 12 years; n = 206) was performed with ANOVA, followed by Stepwise forward regression analyses to restrict the number of comparisons and access the possible effect of multiple confounders. Patients with early onset ADHD present higher scores in novelty seeking in both analyses (respectively P = 0.016 and P = 0.002), but similar cognitive and attention features as compared with the late onset group. These data add to previous evidence that despite a more externalizing profile of early onset ADHD, the overall performance is similar reinforcing the need for awareness and inclusion of the late onset group in DSM-V diagnostic criteria.

ADHD and Mental Health Status in Brazilian School-Age Children

Objective: To assess the prevalence of ADHD, mental health status, and risk factors in a sample of Brazilian children. Method: Target sample consisted of all children from 5 to 13 years registered in the public elementary school. Children with ADHD were compared with those without ADHD for sociodemographic, risk factors, and Child Behavior Checklist (CBCL) symptom dimensions. Multivariate models estimated determinants of ADHD diagnosis. Results: Of the target sample, consents and complete information were obtained from 1,830 children (91.8%). The prevalence rate of ADHD was 5.1% (95% confidence interval [CI] = [4.2, 6.2]). In contrast to controls, children with ADHD presented higher levels of symptoms in the CBCL dimensions. In multivariate analyses, the diagnosis of ADHD was significantly influenced by maternal educational status (p = .019), income class (p = .012), and prenatal exposure to tobacco (p = .032). Conclusion: Prevalence and demographic features of ADHD in Brazil are similar to what has been reported worldwide.

Strategy Selection in ADHD Characteristics Children: A Study in Arithmetic

Objective: It has been argued that ADHD characteristics children have difficulties in selecting the best strategy when they accomplish cognitive tasks. The detrimental influence of these poor strategy skills may be crucial for several aspects of academic achievement such as mathematical learning. Method: Fourth- and fifth-grade children with ADHD symptoms and matched controls were asked to select the better of two rounding strategies in a computational estimation task (i.e., finding the best estimate of two-digit addition problems). Results: (a) Both control and ADHD children correctly executed a selected strategy, (b) ADHD children selected the best strategy less often than controls, (c) ADHD took more time to estimate sums of two-digit addition problems and provided poorer estimates, and (d) different factors predicted best strategy selections in each group. Conclusion: These findings have important implications for further understanding the sources of differences in cognitive performance between ADHD and control children.(J. of Att. Dis. 2019; 23(1) 87-98)

Problems of Self-Concept in a Patient Sample of Hypersexual Men With Attention-Deficit Disorder

Earlier evidence suggests comorbid attention-deficit disorder (ADHD) among those seeking treatment for hypersexual behavior. This article examines which facets of ADHD symptoms are most strongly associated with hypersexual behavior among a patient sample of men (N = 81). ADHD diagnosis was made by 2 clinicians, and symptom characteristics were measured using the Conners' Adult ADHD Rating Scale and the Sexual Compulsivity Scale. Among ADHD symptoms, inattentive features were most prevalent. A stepwise regression analysis revealed that the Problems with Self-Concept subscale of the Conners' Adult ADHD Rating Scale was the strongest predictor of scores on the Sexual Compulsivity Scale. Surprisingly, subscales that measured traits of impulsivity, inattention, memory problems, and hyperactive restlessness did not contribute additional predictive variance in the statistical model. The results of these findings suggest that clinicians should exercise caution in assuming that common characteristics of ADHD, such as impulsivity and hyperactivity, exert the strongest influence on hypersexual behavior. Rather, our results provide evidence that the associated features of ADHD, such as problems with low self-esteem, might be more salient factors in influencing hypersexuality severity among patients with comorbid hypersexual behavior and ADHD.

Le trouble déficitaire de l’attention, avec ou sans hyperactivité (TDA/H) : une approche pluridisciplinaire longitudinale croisée de 36 enfants

In France, attention deficit disorder (ADHD) has traditionally met with two opposing approaches (biological and psychoanalytic). This conflict led us to conduct a multidisciplinary observational study, on a group of 36 children over a period of 1 year. Thirty-six children with ADHD diagnostic (DSM IV), not treated by MPH were included. Initial "multi-field" evaluation (T0) consisted of: neuro-paediatric consultation (Conners questionnaire, Child Behaviour Checklist, reading and writing scores by French tests); semi-structured child psychiatric interview (DSM-IV axis I), structural hypothesis (CFTMEA), existence of narcissistic fragility, parents/child interactions; neuropsychological standardized evaluation (attention and executive functions); psychodynamic interview and projective tests (Rorscharch, CAT or TAT). A therapeutic project is proposed combining MPH and psychotherapy according to the results. A new evaluation 1 year later (T1) included a consultation and a neuropsychological evaluation. RESULTS T0: All parental questionnaires appreciating attention deficit and hyperactivity/impulsivity were significantly pathological. The neuropsychological evaluation showed usual characteristics of ADHD with individual differences. The psychiatric evaluation revealed the frequency of comorbidity in axis I (23% of children with more than two diagnoses, 57% with anxiety disorder, 23 and 3% with oppositional and conduct disorder). FOLLOW UP (T1): Thirty-one children were re-examined (20 treated by MPH and 11 not treated because of parental refusal or particular psychopathological situations). Psychoanalytical psychotherapy, proposed to 28 children, was undertaken with only 19. An improvement in scores for attention and executive tests was registered only in the treated group. The tests confirm deficits of attention and executive functions without correlation with the scores of questionnaires, underlining the need for a neuropsychological evaluation to objectify attention disorders. Projective tests refine and enrich psychiatric evaluation and showed that half of the children had borderline organization. However, structural hypotheses were heterogeneous, suggesting the need for specific therapeutic projects to be devised according to each child. The treated children were the only ones to improve attention deficit. On the other hand, the scores of anxiety are not improved by MPH, emphasizing the indications of psychotherapy if comorbidity is present. Psychotherapeutic care was carried out only among part of the population, because of parental reservations, exacerbated by differences of opinion among professionals and lack of access. This study is innovative, providing precise data on ADHD from a multidisciplinary perspective. Psychopathological comorbidity is high in this population, so the concept of ADHD cannot be limited to a cognitive point of view. These elements and doubts regarding the efficacy of behavioural therapies suggest the need for a rigorous evaluation of analytical psychotherapies independent of MPH to treat attention deficit.

Extended time improves reading comprehension test scores for adolescents with ADHD

Objective: To test the hypotheses that reading comprehension difficulties of adolescent students with ADHD: 1) are related not so much to weak verbal abilities or weak basic reading skills, as to impairments of working memory and processing speed characteristic of ADHD; and 2) that extended time on a test of reading comprehension would yield significantly higher reading comprehension scores than would standard time. Method: Charts of 145 adolescents 13-18 years diagnosed with DSM-IV ADHD and no specific reading disorder after a comprehensive clinical and psycho-educational evaluation, were reviewed to extract 1) word reading and word attack subtest scores from the Woodcock-Johnson Achievement Test or the Wechsler Individual Achievement Test; 2) Index scores from WISC-IV or WAIS-III IQ tests; 3) scores from the Nelson-Denny Reading Test. Results: Mean index scores for verbal comprehension abilities not including reading were in the high average range, but working memory and processing speed index scores were significantly weaker. Under standard time limits 53% were unable to complete the reading comprehension test and only 42.8% were able to score within 1 SD of their IQ verbal comprehension index (VCI). When allowed extended time, 77.9% were able to score within 1 SD of their VCI. T-test comparisons between standard time and extended time were significant at < 0.001. Conclusions: Allowing extended time for adolescents with ADHD to complete tests involving reading may help to compensate for their impairments of working memory and processing speed, allowing them to score closer to their actual verbal abilities.

Visual cortex abnormalities in adults with ADHD: A structural MRI study

Objectives. Most structural imaging studies in ADHD have focused on prefronto-striatal circuits. However, findings remained inconsistent while recent reports point to the posterior parietal cortex as an additional target for research. Moreover, although adult ADHD clinically differs from the childhood presentation little is known about the structural correlates of ADHD in adults. The aim of this study was to clarify the involvement of prefronto-striatal and posterior parietal areas in adult ADHD. Methods. Voxel-based morphometry of high resolution MRI scans was applied to analyze volumetric brain differences between 31 adult patients with ADHD and 31 control subjects. Results. The volume of prefrontal, striatal and parietal gray matter was normal. ADHD patients displayed a significant reduction of gray matter volume bilaterally in the early visual cortex (P < 0.04). Conclusions. The unexpected finding of visual cortex abnormalities might be related to impairments in early-stage, ‘subexecutive” attentional mechanisms. The results support the notion that executive dysfunction may not be the dominant neurobiological characteristic of ADHD at least in adult patients. The visual cortex deserves more consideration as a potentially important site of dysfunction in adult and possibly childhood ADHD.

Community Knowledge and Beliefs About ADHD

AbstractAccurate knowledge and positive attitudes within the community are important for the effective diagnosis, treatment and support of people with ADHD. Most previous research about knowledge and attitudes has focused only on professional groups and parents of children with ADHD. The aim of this study was to explore knowledge about ADHD characteristics and causes, and attitudes towards issues such as medication in the general population. Six hundred and forty-five members of the Australian community, all of whom were parents, completed a questionnaire. The findings showed that the core features of ADHD were well-known, but there were misconceptions and considerable uncertainty about many aspects. Most respondents failed to recognise the genetic basis of the disorder and its potentially lifelong nature. Fathers were less knowledgeable than mothers. Although most participants believed that ADHD is a genuine disorder and recognised the benefits of medication, the majority believed that it is diagnosed too frequently and that medication is prescribed too readily. The study concluded that, in many respects, the public is not well-informed about ADHD and suggested that the media may have an important role in enhancing community awareness of the disorder through responsible, sensitive and accurate reporting.

P03-162 - The ADHD cluster: comparing aples with elephants?

AimTo study the differential psychopathology of ADHD according to the Conners and ICD/DSM criteria.MethodStudying hyperactivity, attention and impulsivity features in children in relation to sensory processing difficulties, specific cognitive impairment and anxiety.An extensive developmental questionnaire and old notes are also used to detect cognitive style, rate of development, communication and learning needsPreliminary results86/136 63% (208-209) children with a learning disability are assessed according to the Conners rating scale. An additional 21 are assessed for attention deficit without the use of the Conners. 27/86 meet the criteria of an attention deficit syndrome according to the Conners. 6/21 are meeting the criteria of ADHD according to international diagnostic criteria (total 33 cases). 13/33 cases display ADHD features of response inhibition and general utilisation behavior. 5 with a hyperactivity syndrome respond tosensory material such as a bean bag, a slow rhythmic voice and a squiggly cushion. 18 cases have no attentional difficulties on preferred activities. Four attentional cases resolve with tailored educational input. One case of ‘typical ADHD’ recovers at resolvement of abuse. 9 display ADHD features as a form of communicating distress. Of the twenty cases 17 are meeting the criteria of an autistic spectrum disorder.ConclusionThis study needs expanding, under experimental conditions and with multiple researchers to optimize blinding. However, this unfinished pilot demonstrates that ADHD criteria do not cater for qualitative differences in presentation and etiology. This has very serious treatment and ethical implications.

Suggestive evidence for linkage of ADHD features in bipolar disorder to chromosome 10p14

Higher rates of bipolar disorder amongst the first-degree relatives of probands with ADHD, and increased rates of ADHD in the relatives of bipolar probands have been reported in many studies. This suggests some commonality in the genetic basis for bipolar disorder and ADHD. We hypothesized that ADHD symptoms in bipolar disorder may access a quantitative subphenotype that is genetically less complex and therefore advantageous for mapping studies. The Wender Utah Rating Scale (WURS) was used to quantify ADHD features in 57 bipolar families collected for linkage studies. The factor structure of the WURS was first examined, and heritability was estimated. Linkage analysis was then conducted using the WURS total score and factor scores as quantitative traits. Three factors were identified: impulsivity and defiant behavior, mood instability and anxiety, and inattention. The total WURS and factor scores were each significantly heritable (0.34 <h(2r) < 0.49) in bipolar families. The inattention factor obtained maximum evidence of linkage on chromosome 10p14 (LOD = 3.35, 25 cM). A LOD score of 2.06 for the total WURS score was found on chromosome 12q24 region. Childhood ADHD features in patients with bipolar disorder are heritable and may represent a genetically distinct dimension of illness. 10p14, in particular may contain a locus for inattention in bipolar disorder. Quantitative dimensional phenotypes such as this may be useful for both mapping of genes and understanding the role of genes in bipolar disorder.

Investigation of attention deficit and hyperactivity disorder in adult patients with atopic dermatitis

Background. Atopic dermatitis (AD) is a common chronic inflammatory disease that is associated with significant psychosocial morbidity and a decrease in health-related quality of life. Attention deficit hyperactivity disorder may be present in atopic dermatitis patients. Objective. The present study aims to investigate the co-presence of ADHD in adult patients with AD. Material and method. The study registered 60 adult patients with AD (48 females and 12 males) and 50 non-atopic control subjects (38 females and 12 males). The AD patient group and the control group were assessed using the Turgay adult Attention-Deficit/Hyperactivity Disorder (ADD/ADHD) DSM-IV-Based Diagnostic Screening and Rating Scale (Turkish Version), which was studied by a team of psychologists and psychiatrists in Turkey for validity, reliability and norms. The scale covers three dimensions of the disease, namely inattention, hyperactivity and impulsivity, and associated features of ADHD. The groups were compared and contrasted in terms of their similarities and differences in ADD/ADHD symptoms. Results. Three sub-dimensions of ADD/ADHD scale (Attention Deficit, Hyperactivity/ Impulsivity and Problem subdivisions) in AD patients were found statistically significantly elevated relative to controls (P<0.001, P<0.001, P<0.001, respectively). Conclusions. In conclusion we established the co-presence of ADHD in AD patients in the adult age group.

A psycho-genetic study of associations between the symptoms of binge eating disorder and those of attention deficit (hyperactivity) disorder

Objective Some recent studies have reported intriguingly strong correlations between ADHD and obesity. This study examined whether ADHD symptoms were more pronounced in adults with symptoms of binge eating disorder (BE) than in their non-binging obese counterparts, and whether the links were stronger with inattentive vs impulsive/hyperactive symptoms. We also assessed the role of the dopamine D3 receptor in ADHD symptoms since the DRD3 gene has been associated with impulsivity and drug addiction – both relevant features of ADHD. Methods A case (BE: n = 60) double-control (normal weight: n = 61 and obese: n = 60) design was employed. Assessments of both childhood and adults ADHD symptoms were made, as well as genotyping of seven markers of DRD3 including the functional Ser9Gly polymorphism. Results Three DRD3 genotypes, including Ser/Ser, had significantly elevated scores on the hyperactive/impulsive symptom scale. In turn, the four ADHD symptom scales were all significantly elevated in the BE and obese groups, who did not differ from each other, compared to those with normal weight. Conclusions Results indicated a role for the D3 receptor in the manifestation of the hyperactive/impulsive symptoms of ADHD, and that symptoms of ADHD are significantly, but not differentially, elevated in obese adults with and without binge eating. Our findings suggest that ADHD screening in adults seeking treatment for obesity, including those with BE, may be warranted as methods used to treat ADHD may help some to better manage overeating and other factors contributing to weight gain.

Changes in Caregiver Strain Over Time in Young Adolescents With ADHD

Objective: The objectives of this study were to identify the relationships between caregiver strain among parents of young adolescents with ADHD and child characteristics during a 1-year period. Method: Parents of 52 middle-school-aged youth with ADHD participated in this study and completed two evaluations 1 year apart. Results: Ratings of oppositional and delinquent behavior best predicted levels of caregiver strain, and change over time did not significantly add to the equation. Patterns of change in caregiver strain indicated important individual differences. Conclusion: Oppositional, delinquent behavior was the best predictor of caregiver strain and suggests that preventing and treating these child behavior problems should be a high priority when working with young adolescents with ADHD. Given the variability in parent responses to changes in oppositional and delinquent behavior, it may also be important to address personal coping strategies for parents of youth exhibiting high rates of these behaviors.

Language Profiles in ASD, SLI, and ADHD

Developmental disorders might differ in their language profiles when using parent reports. The first study indicated that school aged children with ASD have similar language profiles as children with ADHD. Both groups had relatively more difficulties with pragmatics than with structural language aspects. The second study indicated that both preschoolers with ASD and those with SLI show the opposite pattern, thus having relatively more difficulties with structural language aspects than with pragmatics. Finally, an increase in the presence of ADHD characteristics of impulsivity in these preschoolers is associated with an increase in language difficulties, while there is no such relation with inattention. It seems useful to evaluate the communication abilities of children regularly in the course of development and take ADHD characteristics into account. Finally recommendations on clinical use of the Children's Communication Checklist-2 (CCC-2, Bishop 2003) are discussed.

Diagnostic Group Differences in Parent and Teacher Ratings on the BRIEF and Conners' Scales

Objective: Behavioral rating scales are common instruments used in evaluations of ADHD and executive function. It is important to explore how different diagnostic groups perform on these measures, as this information can be used to provide criterion-related validity evidence for the measures. Method: Data from 92 children and adolescents were used to examine differences among participants in a No Diagnosis group, ADHD group, and Other Clinical group in terms of parent and teacher ratings on the Behavior Rating Inventory of Executive Function (BRIEF) and Conners' Rating Scales Revised—Short Form. Results: Participants in the ADHD and Other Clinical groups generally received similar scores on the scales, and both groups were generally rated higher in ADHD characteristics and executive dysfunction than were participants in the No Diagnosis group. Conclusion: Although the measures were successful at distinguishing clinical from nonclinical participants, their ability to distinguish among different clinical groups deserves further investigation.
