Attention deficit hyperactivity disorder (ADHD) is a frequently diagnosed disorder in child- and adulthood with a high impact affecting multiple facets of social life. Therefore, patients suffering from ADHD are at high risk to be confronted with stigma, prejudices, and discrimination. A review of the empirical research in the field of ADHD with regard to stigma was performed. The findings of investigations in this field were clustered in different categories, including stigma in children with ADHD, stigma in adults with ADHD, stigma in relatives or in people close to a patient with ADHD, and the influence of stigma on authorities’ attitudes toward patients with ADHD. Variables identified to contribute to stigma in ADHD are public’s uncertainty concerning the reliability/validity of an ADHD diagnosis and the related diagnostic assessment, public’s perceived dangerousness of individuals with ADHD, socio-demographical factors as age, gender, and ethnicity of the respondent or the target individual with ADHD, stigmatization of ADHD treatment, for example public’s skepticism toward ADHD medication and disclosure of diagnostic status as well as medication status of the individual with ADHD. The contribution of stigma associated with ADHD can be conceptualized as an underestimated risk factor, affecting treatment adherence, treatment efficacy, symptom aggravation, life satisfaction, and mentally well-being of individuals affected by ADHD. Public as well as health professionals’ concepts about ADHD are highly diverse, setting individuals with an ADHD diagnosis at greater risk to get stigmatized.
ObjectivesIn general, assessment tools for stigma in mental disorders such as attention deficit hyperactivity disorder (ADHD) are lacking. Moreover, misbeliefs and misconceptions about ADHD are common, in particular with regard to the adult form of ADHD. The aim of the present study was to develop a questionnaire measuring stigma in adults with ADHD and to demonstrate its sensitivity.MethodsA questionnaire initially containing 64 items associated with stigma in adults with ADHD was developed. A total number of 1261 respondents were included in the analyses. The psychometric properties were investigated on a sample of 1033 participants. The sensitivity of the questionnaire was explored on 228 participants consisting of teachers, physicians and control participants.ResultsThirty-seven items were extracted due to exploratory factor analysis (EFA) and the internal consistency of items. Confirmatory factor analysis (CFA) revealed good psychometric properties of a 6-factor structure. Teachers and physicians differed significantly in their stigmatizing attitudes from control participants.ConclusionsThe present data shed light on various dimensions of stigma in adult ADHD. Reliability and Social Functioning, Malingering and Misuse of Medication, Ability to Take Responsibility, Norm-violating and Externalizing Behavior, Consequences of Diagnostic Disclosure and Etiology represent critical aspects associated with stigmatization.
ObjectivesSince the elimination of items associated with Sluggish Cognitive Tempo (SCT) during the transition from DSM-III to DSM-IV from the diagnostic criteria of Attention-deficit Hyperactivity Disorder (ADHD), interest in SCT and its associated cognitive as well as emotional and social consequences is on the increase. The current review discusses recent findings on SCT in clinical as well as community based ADHD populations. The focus is further on clinical correlates of SCT in populations different from ADHD, SCT’s genetic background, SCT’s association with internalizing and other behavioral comorbidities, as well as SCT’s association with social functioning and its treatment efficacy.MethodA systematic review of empirical studies on SCT in ADHD and other pathologies in PsycInfo, SocIndex, Web of Science and PubMed using the key terms “Sluggish Cognitive Tempo”, “Cognitive Tempo”, “Sluggish Tempo” was performed. Thirty-two out of 63 studies met inclusion criteria and are discussed in the current review.Results/ConclusionFrom the current literature, it can be concluded that SCT is a psychometrically valid construct with additive value in the clinical field of ADHD, oppositional defiant disorder (ODD), internalizing disorders and neuro-rehabilitation. The taxonomy of SCT has been shown to be far from consistent across studies; however, the impact of SCT on individuals’ functioning (e.g., academic achievement, social interactions) seems remarkable. SCT has been shown to share some of the genes with ADHD, however, related most strongly to non-shared environmental factors. Future research should focus on the identification of adequate SCT measurement to promote symptom tailored treatment and increase studies on SCT in populations different from ADHD.Electronic supplementary materialThe online version of this article (doi:10.1186/2049-9256-2-5) contains supplementary material, which is available to authorized users.
Highlights• A new software toolbox is introduced for layer-specific functional MRI: LAYNII.• LAYNII is a suite of command-line executable C++ programs for Linux, Windows, and macOS.• LAYNII is designed for layer-fMRI data that suffer from SNR and coverage constraints.• LAYNII performs layerification in the native voxel space of functional data.• LAYNII performs layer-smoothing, GE-BOLD vein removal, QA, and VASO analysis. AbstractHigh-resolution fMRI in the sub-millimeter regime allows researchers to resolve brain activity across cortical layers and columns non-invasively. While these high-resolution data make it possible to address novel questions of directional information flow within and across brain circuits, the corresponding data analyses are challenged by MRI artifacts, including image blurring, image distortions, low SNR, and restricted coverage. These challenges often result in insufficient performance accuracy of conventional analysis pipelines. Here we introduce a new software suite that is specifically designed for layer-specific functional MRI: LAYNII. This toolbox is a collection of commandline executable programs written in C/C++ and is distributed open-source and as pre-compiled binaries for Linux, Windows, and macOS. LAYNII is designed for layer-fMRI data that suffer from SNR and coverage constraints and thus cannot be straightforwardly analysed in alternative software packages. Some of the most popular programs of LAYNII contain 'layerification' and columnarization in the native voxel space of functional data as well as many other layer-fMRI specific analysis tasks: layerspecific smoothing, vein-removal of GE-BOLD data, quality assessment of artifact dominated sub-millimeter fMRI, as well as analyses of VASO data. layer-fMRI | layer fmri | laminar fMRI | columnar fMRI | submillimeter fMRI | fMRI QA | cortical depth-dependent fMRI Correspondence: renzohuber@gmail.com Graphical abstract Huber et al. | bioRχiv | June 12, 2020 | 1-20
Objectives: Attention deficit hyperactivity disorder (ADHD) is understood as a developmental disorder which shares common characteristics between childhood, adolescence and adulthood. However, ADHD is widely associated with misconceptions and misbeliefs which can lead to stigmatization. Teachers have an important role for the individual development as they accompany students for a long period of time. The aim of the present study was to explore stigmatizing attitudes in teachers towards adults with ADHD, thereby focusing on the developmental trajectory of the condition. Furthermore, it was aimed to identify factors contributing to prevention and intervention of stigmatization in ADHD. Methods: Stigma responses of 170 teachers and 170 comparison participants were measured and compared with a recently developed tool for the assessment of stigmatization towards adults with ADHD. Furthermore, the contribution of knowledge about ADHD and the frequency of contact with adults with ADHD to stigmatization were explored.Results: Teachers showed significantly less stigmatizing attitudes than comparison participants in various dimensions, including Reliability and Social Functioning, Malingering and Misuse of Medication and the total scale. With regard to teachers, frequency of contact with adults with ADHD was not related to stigma. However, knowledge about the disorder was negatively correlated with stigma in teachers, indicating lower expressed stigma with increasing knowledge about adult ADHD. Conclusions:Teachers demonstrated more sensitized attitudes towards stigma in adults with ADHD than comparison participants. Since the present results indicate that knowledge about ADHD increase the sensitivity towards the disorder, special education programs for the community may have the potential to reduce stigmatization towards adults with ADHD. Possibilities for intervention strategies of stigmatization in educational settings were discussed.
