From ABCs to ADHD : the role of schooling the construction of behaviour disorder and the production of disorderly objects

Discussion of Attention-Deficit/Hyperactivity Disorder (ADHD) in the media, and thus much popular discourse, typically revolves around the possible causes of disruptive behaviour and the “behaviourally disordered” child. The usual suspects - too much television and video games, food additives, bad parenting, lack of discipline and single mothers – feature prominently as potential contributors to the spiralling rate of ADHD diagnosis in Western industrialised nations, especially the United States and Australia. Conspicuously absent from the field of investigation, however, is the scene of schooling and the influence that the discourses and practices of schooling might bring to bear upon the constitution of “disorderly behaviour” and subsequent recognition of particular children as a particular kind of “disorderly”. This paper reviews a sample of the literature surrounding ADHD, in order to question the function of this absence and, ultimately, make an argument for an interrogation of the school as a site for the production of disorderly objects.

Psychiatric symptoms in idiopathic rapid-eye-movement sleep behaviour disorder

Le trouble comportemental en sommeil paradoxal (TCSP) idiopathique est caractérisé par une activité motrice indésirable et souvent violente au cours du sommeil paradoxal. Le TCSP idiopathique est considéré comme un facteur de risque de certaines maladies neurodégénératives, particulièrement la maladie de Parkinson (MP) et la démence à corps de Lewy (DCL). La dépression et les troubles anxieux sont fréquents dans la MP et la DCL. L’objectif de cette étude est d’évaluer la sévérité des symptômes dépressifs et anxieux dans le TCSP idiopathique. Cinquante-cinq patients avec un TCSP idiopathique sans démence ni maladie neurologique et 63 sujets contrôles ont complété la seconde édition du Beck Depression Inventory (BDI-II) et le Beck Anxiety Inventory (BAI). Nous avons aussi utilisé le BDI for Primary Care (BDI-PC) afin de minimiser la contribution des facteurs confondant dans les symptômes dépressifs. Les patients avec un TCSP idiopathique ont obtenu des scores plus élevés que les sujets contrôles au BDI-II (9.63 ± 6.61 vs. 4.32 ± 4.58; P < 0.001), au BDI-PC (2.20 ± 2.29 vs. 0.98 ± 1.53; P = 0.001) et au BAI (8.37 ± 7.30 vs. 3.92 ± 5.26; P < 0.001). Nous avons également trouvé une proportion plus élevée des sujets ayant des symptômes dépressifs (4/63 ou 6% vs. 12/55 ou 22%; P = 0.03) ou anxieux (9/50 or 18% vs. 21/43 ou 49%; P = 0.003) cliniquement significatifs. La proportion des sujets ayant des symptômes dépressifs cliniquement significatifs ne change pas en utilisant le BDI-PC (11/55 or 20%) Les symptômes dépressifs et anxieux sont fréquents dans le TCSP idiopathique. L’examen de routine des patients avec un TCSP idiopathique devrait inclure un dépistage systématique des symptômes dépressifs et anxieux afin de les prévenir ou les traiter.

Isolated mediotegmental lesion causing narcolepsy and rapid eye movement sleep behaviour disorder: a case evidencing a common pathway in narcolepsy and rapid eye movement sleep behaviour disorder

Narcolepsy is usually an idiopathic disorder, often with a genetic predisposition. Symptomatic cases have been described repeatedly, often as a consequence of hypothalamic lesions. Conversely, REM (rapid eye movement) sleep behaviour disorder (RBD) is usually a secondary disorder, often due to degenerative brain stem disorders or narcolepsy. The case of a hitherto healthy man is presented, who simultaneously developed narcolepsy and RBD as the result of an acute focal inflammatory lesion in the dorsomedial pontine tegmentum in the presence of normal cerebrospinal fluid hypocretin-1 levels and in the absence of human lymphocyte antigen haplotypes typically associated with narcolepsy and RBD (DQB1*0602, DQB1*05). This first observation of symptomatic narcolepsy with RBD underlines the importance of the mediotegmental pontine area in the pathophysiology of both disorders, even in the absence of a detectable hypocretin deficiency and a genetic predisposition.

Sleepwalking, REM sleep behaviour disorder and overlap parasomnia in patients with Parkinson's disease

BACKGROUND/AIMS In a questionnaire survey, we identified 36 (9%) of 417 Parkinson's disease (PD) patients with sleepwalking (SW); 72% of them also had a history of REM sleep behaviour disorder (RBD). We aimed to assess the clinical and polysomnographic characteristics of SW in PD and to compare them to patients with PD with and without a history of RBD. METHODS We performed video-polysomnography and detailed clinical examination in 30 PD patients from the above-mentioned survey: 10 patients with a history of SW, 10 patients with a history of RBD, and 10 patients with no history of either SW or RBD. RESULTS PD patients with SW had higher depression, anxiety and Hoehn & Yahr scores and lower activities of daily living scores than patients without a history of RBD but did not differ from patients with RBD. Patients with SW and RBD also had more often dyskinesia and hallucinations. By polysomnography, RBD was observed in 8 patients with SW and in all patients with a history of RBD. A total of 5 patients without a history of either SW or RBD had REM sleep without atonia without behavioural peculiarities. CONCLUSION SW in PD is associated with depression, higher disease severity and functional disability. The simultaneous occurrence of SW and RBD (overlap parasomnia) in most patients suggests a common underlying disturbance of motor control during sleep in PD, with variable manifestations in different sleep stages.

“I’m Happy with Who I Am” : A Discursive Analysis of the Self-characterisation Practices of Boys in “Behaviour” Schools

In this chapter, I draw on poststructural theories of language to examine the self-characterisation practices of 33 boys attending special schools for students with disruptive behaviour. During a semi-structured interview, each boy was asked to describe his personality and then to choose from a selection of positive/negative word pairs. The objective was to determine whether these young people would characterise themselves in positive or negative ways. Participants were then asked if there was anything they would change about themselves if they could. Responses were analysed and compared against a discourse model developed from media reports and interviews with their principals. Findings suggest that while discourse may well ‘form the objects of which it speaks’ (Foucault, 1972, p. 49) in the eyes of teachers, principals, psychiatrists and paediatricians, it also offers a means through which the constituted subject can re-author itself in a more positive frame.

A disordered approach

It seems a new behaviour disorder is identified every week. Forms of conduct once simply regarded as part of the human condition, are rapidly being reinterpreted as types of mental illness. Individuals are no longer simply quiet or shy, they are reclassified as suffering from Generalised Social Phobia, or Selective Mutism, or Avoidant Personality Disorder. Others are no longer simply unpopular or obnoxious, they are reclassified as Borderline Personality Disorder, or Antisocial Personality Disorder. Still more are no longer lively or boisterous, they have Attention Deficit Hyperactivity Disorder, or Conduct Disorder, or Oppositional Defiance Disorder.

Disproportionate over-representation of Indigenous students in New South Wales government special schools

A significant gap exists in the Australian research literature on the disproportionate over-representation of minority groups in special education. The aim of this paper is to make a contribution to the research evidence-base by sketching an outline of the issue as it presents in Australia’s largest education system in the state of New South Wales. Findings from this research show that Indigenous students are equally represented in special schools enrolling students with autism, physical, sensory, and intellectual disabilities, but significantly over-represented in special schools enrolling students under the categories of emotional disturbance, behaviour disorder and juvenile detention. Factors that might influence the disproportionate over-representation of Indigenous children and young people are discussed, and based on these observations, some practical implications for policy and practice are provided.

Threat vigilance in child witnesses of domestic violence: a pilot study utilizing the ambiguous situations paradigm

Research has found that children exposed to family violence exhibit higher rates of maladjustment. We review relevant literature on family violence, marital conflict, and cognitive factors implicated in child behaviour problems. A bias toward perceiving threat in ambiguous contexts has been identified as one factor mediating both aggressive and anxious behaviour disorders. We conducted a study utilizing the ambiguous situations paradigm to assess whether children exposed to violent spousal conflict were more likely than children not exposed to violence (divided into children with an externalizing behaviour disorder and non-clinic children) to perceive threat in two classes of ambiguous situations: Peer and Inter-Parental. The results indicated that children exposed to violent spousal conflict perceived more threat in parental situations than either of the other two groups. A number of considerations were taken into account given the exploratory nature of the study, particularly sample limitations. We conclude with suggestions for improvements to the research design and the further relevance of exploring cognitive factors involved in the adjustment of children from backgrounds of violence.

The psychology of containment : mis/representing emotional and behavioural difficulties in Australian schools

The number of students in special schools has increased at a rapid rate in some Australian states, due in part to increased enrolment under the categories of emotional disturbance (ED) and behaviour disorder (BD). Nonetheless, diagnostic distinctions between ED and BD are unclear. Moreover, despite international findings that students with particular backgrounds are over-represented in special schools, little is known about the backgrounds of students entering such settings in Australia. This study examined the government school enrolment data from New South Wales, the most populous of the Australian states. Linear and quadratic trends were used to describe the numbers and ages of students enrolled in special schools in the ED and BD categories. Changes between 1997 and 2007 were observed. Results showed an over-representation of boys that increased across the decade and a different pattern across age for boys and girls. Consistent with international findings, these results indicate that trends in special school placements are unrelated to disability prevalence in the population. Rather, it is suggested that schools act to preserve time and resources for others by removing their more challenging students: most typically, boys.

What is the relationship between the term 'ADHD' and the object it purports to represent?

This paper addresses the question: what is the relationship between the term ADHD, and the object it purports to represent? While the most familiar linguistic position—Referential Theory— suggests that the term constitute an etymological peg corresponding to a particular part of nature, there are other, arguably more sophisticated, philosophical approaches that point to an altogether more complex relationship. These approaches do not assume that ‘behaviour disorders’, such as ADHD, are objective facts of nature, facts to which words can simply be adhered. Using the work of Wittgenstein, the intention here is to use the philosophy of language to destabilise, not just the relationship between the term ADHD and the idea to which it applies, but also the coherence of the notion of ADHD itself.

Sleep motor activity in parkinsonian syndromes at onset: a prospective study to determine potential diagnostic and prognostic markers

Aim of this study is to describe the possible diagnostic value of sleep disturbances in the differential diagnosis of neurodegenerative diseases characterized by parkinsonism at onset. 42 consecutive patients with parkinsonian features and disease duration up to 3 years were included in the BO-ProPark study. Each patient was evaluated twice, at baseline (T0) and 16 months later (T1). Patients were diagnosed as Parkinson disease (PD, 27 patients), PD plus (PD with cognitive impairment/dementia or dysautonomia, 4 patients) and parkinsonian syndrome (PS, 11 patients). All patients underwent a full night video-polysomnography scored by a neurologist blinded to the clinical diagnosis. Sleep efficiency and total sleep time were reduced in all patients; wake after sleep onset was higher in patients with atypical parkinsonisms than in PD patients. No significant differences between groups of patients were detected in other sleep parameters. The mean percentage of epochs with enhanced tonic muscle EMG activity during REM sleep was higher in PD plus and PS than in PD. No difference in phasic muscle EMG activity during REM sleep was seen between the two groups. REM behaviour disorder was more frequent in PD plus and PS than in PD patients. Our data suggest that REM sleep motor control is more frequently impaired at disease onset in patients with PS and PD plus compared to PD patients. The presence of RBD or an enhanced tonic muscle EMG activity in a patient with recent onset parkinsonian features should suggest a diagnosis of atypical parkinsonism, rather than PD. More data are needed to establish the diagnostic value of these features in the differential diagnosis of parkinsonisms. The evaluation of sleep disorders may be a useful tool in the differential diagnosis of parkinsonism at onset.

Seclusion use with children and adolescents: an Australian experience

Objective: To summarize the current state of knowledge on the use of seclusion and restraint with children and adolescents and to report the findings of an exploratory study to identify factors that place a child or adolescent at increased risk of seclusion during their admission. Method: Literature searches were undertaken on MEDLINE, CINAHL and PsycINFO databases. Articles were identified that focused specifically on seclusion and restraint use with children and adolescents or contained material significant to this population. The study reports findings from a retrospective review of patient charts, seclusion registers and staffing from an Australian acute inpatient facility. Results: The data available in regard to seclusion use in this population is limited and flawed. Further research is needed on the use and outcomes of seclusion and restraint and on alternative measures in the containment of dangerousness. Both the literature and this study find that patients with certain factors are at increased risk of being secluded during an inpatient stay. These factors include being male, diagnoses of disruptive behaviour disorder and a previous history of physical abuse. Staffing factors did not show a relationship to the use of seclusion. Conclusions: There are patient factors that predict increased risk of seclusion; these factors and their interrelationships require further elucidation. Further research is also needed on the outcomes, both positive and negative, of seclusion use and of alternatives to seclusion.

Oculo-visual dysfunction in Parkinson's disease

This review describes the oculo-visual problems likely to be encountered in Parkinson's disease (PD) with special reference to three questions: (1) are there visual symptoms characteristic of the prodromal phase of PD, (2) is PD dementia associated with specific visual changes, and (3) can visual symptoms help in the differential diagnosis of the parkinsonian syndromes, viz. PD, progressive supranuclear palsy (PSP), dementia with Lewy bodies (DLB), multiple system atrophy (MSA), and corticobasal degeneration (CBD)? Oculo-visual dysfunction in PD can involve visual acuity, dynamic contrast sensitivity, colour discrimination, pupil reactivity, eye movement, motion perception, and visual processing speeds. In addition, disturbance of visuo-spatial orientation, facial recognition problems, and chronic visual hallucinations may be present. Prodromal features of PD may include autonomic system dysfunction potentially affecting pupil reactivity, abnormal colour vision, abnormal stereopsis associated with postural instability, defects in smooth pursuit eye movements, and deficits in visuo-motor adaptation, especially when accompanied by idiopathic rapid eye movement (REM) sleep behaviour disorder. PD dementia is associated with the exacerbation of many oculo-visual problems but those involving eye movements, visuo-spatial function, and visual hallucinations are most characteristic. Useful diagnostic features in differentiating the parkinsonian symptoms are the presence of visual hallucinations, visuo-spatial problems, and variation in saccadic eye movement dysfunction.

Étiologie génétique et cognitive de l’association entre les habiletés en lecture et les dimensions du trouble déficitaire de l’attention avec ou sans hyperactivité (TDAH)

La présente thèse examine les associations entre les dimensions du TDAH et les habiletés en lecture sur les plans phénotypique, génétique et cognitif. En premier lieu, les associations entre les dimensions du TDAH (inattention et hyperactivité/impulsivité) et les habiletés en lecture (décodage et compréhension en lecture) chez des enfants au début du primaire (6-8 ans) ont été examinées. Les résultats révèlent des associations similaires. Toutefois, seules celles entre l’inattention et les habiletés en lecture demeurent après que l’hyperactivité/impulsivité, les symptômes de trouble du comportement et les habiletés non verbales aient été contrôlés. De plus, les associations entre l’inattention et les habiletés en lecture s’expliquent en grande partie par des facteurs génétiques. En second lieu, les associations entre les dimensions du TDAH et les habiletés en lecture (lecture de mots et exactitude/vitesse lors de la lecture d’un texte) ont été étudiées à 14-15 ans. Seule l’inattention demeure associée aux habiletés en lecture après que l’hyperactivité/impulsivité, les habiletés verbales et les habiletés non verbales aient été contrôlées. L’inattention et les habiletés en lecture sont aussi corrélées sur le plan génétique, mais ces corrélations deviennent non significatives lorsque les habiletés verbales sont contrôlées. En dernier lieu, des habiletés cognitives ont été étudiées comme mécanismes sous-jacents potentiels de l’association entre l’inattention et les habiletés en lecture (décodage et compréhension en lecture) à l’enfance. Il apparait que la conscience phonologique, la vitesse de dénomination de chiffres, le traitement temporel bimodal et le vocabulaire sont des médiateurs de l’association entre l’inattention et le décodage alors que la conscience phonologique, la vitesse de dénomination de chiffres et de couleurs et le vocabulaire sont des médiateurs de l’association entre l’inattention et la compréhension en lecture. De plus, des facteurs génétiques communs ont été observés entre certains médiateurs (conscience phonologique, vitesse de dénomination des chiffres et traitement temporel bimodal), l’inattention et le décodage. Somme toute, la présente thèse montre que des facteurs génétiques expliquent en partie ces associations à l’enfance et l’adolescence. Des médiateurs cognitifs sous-tendent ces associations, possiblement par des processus génétiques et environnementaux qui devront être précisés dans le futur.
