A qualitative study of Australian GPs' attitudes and practices in the diagnosis and management of attention-deficit/hyperactivity disorder (ADHD)

Background. The importance of general practice involvement in the care of attention-deficit/hyperactivity disorder (ADHD) is increasing due to the rising numbers of patients who present with the disorder. It has been suggested by consensus bodies that GPs should be identifying and referring patients at the severe end of the ADHD spectrum and managing those with less severe symptoms. However, GPs' views of their role in ADHD care are unknown. Objective. Our aim was to explore the attitudes and practices of Australian GPs towards the diagnosis and management of ADHD. Methods. We conducted a series of focus groups to explore GPs' beliefs regarding the causes of ADHD, their perceived role in ADHD diagnosis and management and their views on the role of behaviour therapies and pharmacotherapies in ADHD management. The subjects were 28 GPs in six focus groups. Results. GPs in this study did not want to be the primary providers of care for patients with ADHD. Participants indicated a preference to refer the patient to medical specialists for diagnosis and treatment of ADHD, and expressed low levels of interest in becoming highly involved in ADHD care. Concerns about overdiagnosis and misdiagnosis of the disorder, diagnostic complexity, time constraints, insufficient education and training about the disorder, and concerns regarding misuse and diversion of stimulant medications were the reasons cited for their lack of willingness. Conclusions. The Australian GPs in this study identify a role for themselves in ADHD care which is largely supportive in nature, and involves close liaison with specialist services.

Reaction time assessment in children with ADHD

Attention deficit, impulsivity and hyperactivity are the cardinal features of attention deficit hyperactivity disorder (ADHD) but executive function (EF) disorders, as problems with inhibitory control, working memory and reaction time, besides others EFs, may underlie many of the disturbs associated with the disorder. OBJECTIVE: To examine the reaction time in a computerized test in children with ADHD and normal controls. METHOD: Twenty-three boys (aged 9 to 12) with ADHD diagnosis according to Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, 2000 (DSM-IV) criteria clinical, without comorbidities, Intelligence Quotient (IQ) >89, never treated with stimulant and fifteen normal controls, age matched were investigated during performance on a voluntary attention psychophysical test. RESULTS: Children with ADHD showed reaction time higher than normal controls. CONCLUSION: A slower reaction time occurred in our patients with ADHD. This findings may be related to problems with the attentional system, that could not maintain an adequate capacity of perceptual input processes and/or in motor output processes, to respond consistently during continuous or repetitive activity.

Development and applications of the SWAN rating scale for assessment of attention deficit hyperactivity disorder: a literature review

This study reviewed the use of the Strengths and Weaknesses of Attention-Deficit/Hyperactivity-symptoms and Normal-behaviors (SWAN) rating scale in diagnostic and evolutive approaches to attention deficit hyperactivity disorder (ADHD) and in correlational studies of the disorder. A review of articles published in indexed journals from electronic databases was conducted and 61 articles on the SWAN scale were analyzed. From these, 27 were selected to a) examine use of SWAN in research on attention disorders and b) verify evidence of its usefulness in the areas of genetics, neuropsychology, diagnostics, psychiatric comorbidities, neuroimaging, pharmacotherapy, and to examine its statistical reliability and validity in studies of diverse populations. This review of articles indicated a growing use of the SWAN scale for diagnostic purposes, for therapy, and in research on areas other than ADHD, especially when compared with other reliable scales. Use of the scale in ADHD diagnosis requires further statistical testing to define its psychometric properties.

Accroissement de la prévalence du TDA/H, de la consommation de psychostimulants et des symptômes dépressifs : l’importance du contexte social évaluée à partir des effets d’âge, de période et de cohorte

La présente thèse de doctorat visait d’abord à valider les résultats des études antérieures démontrant un accroissement de la prévalence des problèmes de santé mentale et ensuite, à évaluer l’importance du contexte social dans l’explication des changements de prévalence, à partir des effets d’âge, de période et de cohorte. L’atteinte de ces objectifs s’est faite à partir de deux études empiriques, chacune ciblant sa propre problématique en santé mentale. La première étude, basée sur les données de l’Enquête longitudinale nationale sur les enfants et les jeunes (ELNEJ) de Statistique Canada, a permis de conclure à un accroissement réel de la prévalence du diagnostic de trouble déficitaire de l’attention/hyperactivité (TDA/H) et de la consommation de psychostimulants chez les enfants canadiens entre 1994 et 2007. Toutefois, cette tendance n’est ni constante, ni universelle, puisque des effets de période et d’âge apparaissent clairement : l’augmentation des prévalences est uniquement remarquée dans les années 2000, et survient seulement chez les enfants d’âge scolaire. L’identification d’inégalités de prévalence dues à la période historique et à l’âge des enfants souligne l’importance du contexte social dans la problématique du diagnostic de TDA/H et de la consommation de psychostimulants. La seconde étude a été réalisée à partir des données du Panel Study of Belgian Households (PSBH) et cherchait à expliquer l’accroissement des symptômes dépressifs observé ces vingt dernières années chez les adultes belges. L’utilisation de l’analyse multiniveaux longitudinale permettant la distinction des effets d’âge et des effets de cohortes a été privilégiée. Bien que l’intensité des symptômes dépressifs ait varié de manière relativement importante chez les individus au cours des années 1990, nos conclusions démontrent que les symptômes auto-rapportés de dépression sont davantage associés aux conditions de vie, qu’à la personnalité. L’augmentation résulte d’un effet de la succession des cohortes, où les individus des cohortes les plus récentes rapportent toujours une plus grande intensité de symptômes dépressifs que les individus des cohortes précédentes. Les membres d’une même cohorte de naissance partagent donc des expériences communes à un âge similaire, ce qui a un impact durable sur leurs comportements et sur leur santé mentale. De manière générale, les résultats des deux articles empiriques ont, chacun à leur manière, confirmé la réalité de l’accroissement des problèmes de santé mentale dans les sociétés occidentales contemporaines, et permis de constater que la prévalence diffère selon l’âge et la cohorte de naissance des individus, ainsi que selon la période historique, renforçant ainsi l’hypothèse de l’importance des facteurs sociaux dans l’étiologie des problèmes de santé mentale. Bien que la nature de ces facteurs n’ait pu être testée de manière directe, de nombreuses explications sociales furent tout de même proposées. À cet égard, des changements dans les normes comportementales associées à l’âge, dans les normes sociales, dans la conceptualisation des troubles mentaux, des modifications dans la sphère éducative, ainsi que des innovations pharmacologiques, médicales et technologiques constituent des explications sociales aux effets d’âge, de période et de cohorte qui ont été observés.

Efeitos de um programa pedagógico-comportamental sobre TDAH para professores do ensino fundamental

Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES)

Avaliação comportamental de crianças com Síndrome do Respirador Bucal

A Síndrome do Respirador Bucal (SRB) ocasiona características físicas e comportamentais que interferem na qualidade de vida da criança. O Transtorno do Déficit de Atenção e Hiperatividade (TDAH) pode estar relacionado à respiração bucal no indivíduo, bem como a presença de Distúrbios Respiratórios do Sono (DRS). Por outro lado, estudos indicam que a adenotonsilectomia reduz a ocorrência de comportamentos sugestivos de TDAH em portadores de SRB, bem como produz melhora significativa nos DRS. Pretendeu-se caracterizar a condição sociodemográfica e de risco e analisar padrões comportamentais indicadores de TDAH e os hábitos de sono de crianças com diagnóstico de Síndrome do Respirador Bucal, observados antes e após a realização de cirurgia de adenoidectomia, tonsilectomia ou adenotonsilectomia. Participaram 44 crianças, de ambos os gêneros, entre dois e 12 anos de idade, atendidas pelo Serviço de Otorrinolaringologia de um hospital universitário, assim como seus cuidadores e professores. A coleta de dados foi realizada mediante aplicação de: (1) Roteiros de entrevistas denominados Informações sobre a família e a criança e História desenvolvimental e médica, aplicados com os cuidadores; (2) Lista de Verificação Comportamental para Crianças – versão para pais (CBCL) e dos critérios para diagnóstico de TDAH do DSM-IV; (2) Lista de Verificação Comportamental para Crianças – versão para professores (TRF); (3) Inventário dos hábitos de sono para crianças pré-escolares e Questionário sobre o comportamento do sono, para escolares; (4) Avaliação comportamental pós-cirúrgica, utilizando-se o CBCL e os Inventários do sono, após dois meses da cirurgia; e (5) Entrevista devolutiva. Os respiradores bucais em sua maioria: (a) eram crianças em período escolar; (b) entre sete e nove anos de idade; (c) do gênero feminino; (d) seu principal cuidador tinha o Ensino Médio Completo; (e) renda familiar mensal entre um e dois salários mínimos; (f) constituição familiar original; e, (g) encontravam-se em risco psicossocial moderado. Observou-se que a maioria das crianças deste estudo teve uma gestação dentro de padrões considerados como normais e seu nascimento se deu de forma adequada; no entanto, uma parcela de respiradores bucais desta amostra ficou cianótica durante ou imediatamente após o parto e apresentou problemas respiratórios nos primeiros meses de vida. A respeito do temperamento do bebê no primeiro ano de vida, grande parte teve dificuldade para dormir, em ser mantido ocupado e foi superativo. A maioria dos marcos desenvolvimentais ocorreu em um período considerado dentro dos padrões típicos do desenvolvimento infantil. Os problemas de saúde mais frequentes foram problemas de apetite e problemas de sono. Tanto as crianças pré-escolares quanto as escolares apresentaram melhoras nos comportamentos característicos do TDAH após a cirurgia, de acordo com dados do CBCL (p=0,723). A maioria dos itens do Inventário dos hábitos de sono para crianças pré-escolares teve redução na frequência dos hábitos inadequados e aumento dos adequados. No Questionário sobre o comportamento do sono, uma minoria apresentou problemas de sono na avaliação pós-cirúrgica e a maior parte dos problemas de sono sofreu redução de frequência. As maiores reduções ocorreram em movimenta-se muito enquanto dorme e ronca enquanto dorme (p=0,000). Sugere-se a avaliação multidisciplinar preventiva da respiração bucal e a incorporação de um grupo controle em estudos futuros, composto por indivíduos respiradores nasais.

Attention-deficit hyperactivity disorder symptoms and lead exposure in children: A systematic review of literature

Blood lead levels > 10 µg/dL are known to affect various areas of the brain that influence behavior and cause many other health problems in children. As a result, the Centers for Disease Control and Prevention (CDC) set the blood lead action level at 10 µg/dL. However, recent research provides evidence that blood lead levels <10 µg/dL also may lead to behavioral problems in children. With the recent increase in diagnosis of Attention-Deficit Hyperactivity Disorder (ADHD) in children in the U.S. it is important to determine possible environmental toxins such as lead that may play a role in causing ADHD symptoms. The aim of this systematic review of the literature was to identify recent published studies that examine an association between blood lead levels < 10 µg/dL and ADHD symptoms in children in order to summarize their findings and describe major gaps in the literature. Although available research is limited, the articles reviewed indicate that blood lead at levels much below the CDC action level of 10 µg/dL may affect a child's level of attention, hyperactivity, impulsivity and ADHD diagnosis. Additional prospective research is warranted in order to inform the revision of current blood lead action levels as well as better elucidate the relationship between lead and ADHD diagnoses.^

Attitudes and practices of general practitioners in the diagnosis and management of attention-deficit/hyperactivity disorder

Objective: To assess understanding of, and actual and potential roles in management of attention-deficit/hyperactivity disorder (ADHD) among GPs. Methods: A cross-sectional questionnaire survey of Queensland GPs selected randomly from the Royal Australian College of General Practitioners directory of members was carried out. Main outcome measures were knowledge levels of ADHD, current management practices, referral patterns and self-perceived information and training needs. Results: Three hundred and ninety-nine GPs returned a completed questionnaire (response rate 76%). Roles identified by GPs were: the provisional diagnosis of ADHD and referral to specialist services for confirmation of the diagnosis and initiation of management; assistance with monitoring progress once a management plan was in place; education of the child and their family regarding the disorder; and liaison with the school where necessary. Perceived barriers to increased involvement of GPs were: time and resource constraints of general practice; concerns regarding abuse and addiction liability of prescription stimulants; complex diagnostic issues associated with childhood behavioural problems; and lack of training and education regarding ADHD. Conclusions: General practitioners identify a role for themselves in ADHD care that is largely supportive in nature and involves close liaison with specialist services.

ADHD and fetal alcohol spectrum disorders (FASD).

This multi-author book will discuss the history and clinical presentation of Foetal Alcohol Spectrum Disorders(FASD) i.e Fetal Alcohol Syndrome (FAS) and Alcohol Related Neurodevelopmental Disorder (ARND). These developmental neuropsychiatric disorders result from prenatal exposure to alcohol during any gestational period of pregnancy. The book will particularly address the co-occurring presence of ADHD in patients with FASD. ADHD is the most frequent neuropsychiatric presentation of FASD throughout the lifespan and it is particularly difficult to manage because the underlying pathophysiology is related to prenatal neurotoxic brain injury. Although prenatal alcohol exposure , and the resulting FASD, is recognised as the commonest preventable cause of intellectual disability, many clinicians and educators are not aware that 75 to 80% of the patients with FASD have I.Q.s over 70. Thus, the neuropsychiatric presentation of FASD can often be unrecognised or misunderstood. FASD are the true clinical ' masqueraders' and ADHD is their most likely disguise! The authors are all experienced professionals from a wide range of disciplines working throughout the USA and Canada. They have been involved in the diagnosis, research and management of FASD for many years and this book will bring their collective knowledge regarding management from infancy to adulthood to an inter-professional audienceThis resource was contributed by The National Documentation Centre on Drug Use.

Genrestratifiering och massmedias neutralisering av kritiken mot ADHD : Ett kunskapssociologiskt perspektiv

Genre stratification and the mass media’s neutralization of the critique of ADHD: A sociology of knowledge perspective This study examines how the Swedish mass media has dealt with the opposition against the neuropsychiatric diagnosis ADHD (Attention Deficit Hyperactivity Disorder). Drawing on empirical data from eight of the largest newspapers in Sweden (n=778 articles) the study focuses on the scientific controversy of DAMP, 2000–2006. DAMP (Dysfunction in Attention, Motor Control and Perception) is a diagnostic term denoting difficulties similar to ADHD, and which was used in Sweden at the time of the controversy. The study uncovers the ideological role played by the mass media during the DAMP-controversy, and demonstrates the significance of genre. While the spokespersons for DAMP/ADHD were given exclusive and systematic access to the news genre, the forum of fact-production in the mass media, the critics of DAMP/ADHD were confined to arguing and expressing their opinions in the debate genre. Based on the various effects of genre differences a comprehensive analytical tool for the sociology of knowledge, called genre stratification, is developed in the study 

ADHD and medicalization: consideration of the senses and meanings of symptoms presented by children diagnosed

The present paper is a reflection on the diagnosis of Attention Deficit Hyperactivity Disorder (ADHD) and its relations to the process of medicalization as well as the meanings and perspectives apprehended through three case studies of children diagnosed with such disorder in a doctoral research in which the main purpose was to understand the meanings and peculiarities of ADHD symptomatology .We’ve utilized the model of qualitative research, grounded in psychoanalytic perspective, and conducted the psychodiagnosis for three children who were referred for psychological treatment. The survey found that those children had few experiences of both continence and frustration tolerance. It was evidenced how the school uses the logic of medicalization to try solving the problems with their children when it came to the school dimension. The variety of symptomatic manifestations and psychic dynamics presented by the cases that were studied revealed the weaknesses and inconsistencies of the referred diagnosis.

German validation of the Conners Adult ADHD Rating Scales–self-report (CAARS-S) I: Factor structure and normative data

Attention-deficit/hyperactivity disorder (ADHD) often persists into adulthood. Instruments for diagnosing ADHD in childhood are well validated and reliable, but diagnosis of ADHD in adults remains problematic. Attempts have been made to develop criteria specific for adult ADHD, resulting in the development of self-report and observer-rated questionnaires. To date, the Conners Adult ADHD Rating Scales (CAARS) are the international standard for questionnaire assessment of ADHD. The current study evaluates a German version of the CAARS self-report (CAARS-S).

Variability in the prevalence of adult ADHD in treatment seeking substance use disorder patients: results from an international multi-center study exploring DSM-IV and DSM-5 criteria

Background: Available studies vary in their estimated prevalence of attention deficit/hyperactivity disor-der (ADHD) in substance use disorder (SUD) patients, ranging from 2 to 83%. A better understanding ofthe possible reasons for this variability and the effect of the change from DSM-IV to DSM-5 is needed.Methods: A two stage international multi-center, cross-sectional study in 10 countries, among patientsform inpatient and outpatient addiction treatment centers for alcohol and/or drug use disorder patients. Atotal of 3558 treatment seeking SUD patients were screened for adult ADHD. A subsample of 1276 subjects,both screen positive and screen negative patients, participated in a structured diagnostic interview. 5AdultsResults: Prevalence of DSM-IV and DSM-5 adult ADHD varied for DSM-IV from 5.4% (CI 95%: 2.4–8.3) forHungary to 31.3% (CI 95%:25.2–37.5) for Norway and for DSM-5 from 7.6% (CI 95%: 4.1–11.1) for Hungary to32.6% (CI 95%: 26.4–38.8) for Norway. Using the same assessment procedures in all countries and centersresulted in substantial reduction of the variability in the prevalence of adult ADHD reported in previousstudies among SUD patients (2–83% → 5.4–31.3%). The remaining variability was partly explained byprimary substance of abuse and by country (Nordic versus non-Nordic countries). Prevalence estimatesfor DSM-5 were slightly higher than for DSM-IV.Conclusions: Given the generally high prevalence of adult ADHD, all treatment seeking SUD patientsshould be screened and, after a confirmed diagnosis, treated for ADHD since the literature indicates poorprognoses of SUD in treatment seeking SUD patients with ADHD.

The International ADHD in Substance Use Disorders Prevalence (IASP) study: background, methods and study population

Attention deficit/hyperactivity disorder (ADHD) is an increasingly recognized comorbid condition in subjects with substance use disorders (SUDs). This paper describes the methods and study population of the International ADHD in Substance Use Disorders Prevalence (IASP) study. Objectives of the IASP are to determine the prevalence of ADHD in adult treatment seeking patients with SUD in different countries and SUD populations, determine the reliability and validity of the Adult ADHD Self-report Scale V 1.1 (ASRS) as ADHD screening instrument in SUD populations, investigate the comorbidity profile of SUD patients with and without ADHD, compare risk factors and protective factors in SUD patients with and without a comorbid diagnosis of ADHD, and increase our knowledge about the relationship between ADHD and the onset and course of SUD. In this cross-sectional, multi-centre two stage study, subjects were screened for ADHD with the ASRS, diagnosed with the Conner's Adult ADHD Diagnostic Interview for DSM-IV (CAADID), and evaluated for SUD, major depression, bipolar disorder, anti social personality disorder and borderline personality disorder. Three thousand five hundred and fifty-eight subjects from 10 countries were included. Of these 40.9% screened positive for ADHD. This is the largest international study on this population evaluating ADHD and comorbid disorders.
