Fetal alcohol spectrum disorders in Finnish children and adolescents : diagnosis, cognition, behavior, adaptation and brain metabolic alterations

Alcohol consumption during pregnancy can potentially affect the developing fetus in devastating ways, leading to a range of physical, neurological, and behavioral alterations most accurately termed Fetal Alcohol Spectrum Disorders (FASD). Despite the fact that it is a preventable disorder, prenatal alcohol exposure today constitutes a leading cause of intellectual disability in the Western world. In Western countries where prevalence studies have been performed the rates of FASD exceed, for example, autism spectrum disorders, Down’s syndrome and cerebral palsy. In addition to the direct effects of alcohol, children and adolescents with FASD are often exposed to a double burden in life, as their neurological sequelae are accompanied by adverse living surroundings exposing them to further environmental risk. However, children with FASD today remain remarkably underdiagnosed by the health care system. This thesis forms part of a larger multinational research project, The Collaborative Initiative on Fetal Alcohol Spectrum Disorders (the CIFASD), initiated by the National Institute of Alcohol Abuse and Alcoholism (NIAAA) in the U.S.A. The general aim of the present thesis was to examine a cohort of children and adolescents growing up with fetal alcohol-related damage in Finland. The thesis consists of five studies with a broad focus on diagnosis, cognition, behavior, adaptation and brain metabolic alterations in children and adolescents with FASD. The participants consisted of four different groups: one group with histories of prenatal exposure to alcohol, the FASD group; one IQ matched contrast group mostly consisting of children with specific learning disorder (SLD); and two typically-developing control groups (CON1 and CON2). Participants were identified through medical records, random sampling from the Finnish national population registry and email alerts to students. Importantly, the participants in the present studies comprise a group of very carefully clinically characterized children with FASD as the studies were performed in close collaboration with leading experts in the field (Prof. Edward Riley and Prof. Sarah Mattson, Center for Behavioral Teratology, San Diego State University, U.S.A; Prof. Eugene Hoyme, Sanford School of Medicine, University of South Dakota, U.S.A.). In the present thesis, the revised Institute of Medicine diagnostic criteria for FASD were tested on a Finnish population and found to be a reliable tool for differentiating among the subgroups of FASD. A weighted dysmorphology scoring system proved to be a valuable additional adjunct in quantification of growth deficits and dysmorphic features in children with FASD (Study 1). The purpose of Study 2 was to clarify the relationship between alcohol-related dysmorphic features and general cognitive capacity. Results showed a significant correlation between dysmorphic features and cognitive capacity, suggesting that children with more severe growth deficiency and dysmorphic features have more cognitive limitations. This association was, however, only moderate, indicating that physical markers and cognitive capacity not always go hand in hand in individuals with FASD. Behavioral problems in the FASD group proved substantial compared to the typically developing control group. In Study 3 risk and protective factors associated with behavioral problems in the FASD group were explored further focusing on diagnostic and environmental factors. Two groups with elevated risks for behavioral problems emerged: length of time spent in residential care and a low dysmorphology score proved to be the most pervasive risk factor for behavioral problems. The results underscore the clinical importance of appropriate services and care for less visibly alcohol affected children and highlight the need to attend to children with FASD being raised in institutions. With their background of early biological and psychological impairment compounded with less opportunity for a close and continuous caregiver relationship, such children seem to run an especially great risk of adverse life outcomes. Study 4 focused on adaptive abilities such as communication, daily living skills and social skills, in other words skills that are important for gradually enabling an independent life, maintain social relationships and allow the individual to become integrated into society. The results showed that adaptive abilities of children and adolescents growing up with FASD were significantly compromised compared to both typically-developing peers and IQ-matched children with SLD. Clearly different adaptive profiles were revealed where the FASD group performed worse than the SLD group, who in turn performed worse than the CON1 group. Importantly, the SLD group outperformed the FASD group on adaptive behavior in spite of comparable cognitive levels. This is the first study to compare adaptive abilities in a group of children and adolescents with FASD relative to both a contrast group of IQ-matched children with SLD and to a group of typically-developing peers. Finally, in Study 5, through magnetic resonance spectroscopic imaging (MRS) evidence of longstanding neurochemical alterations were observed in adolescents and young adults with FASD related to alcohol exposure in utero 14-20 years earlier. Neurochemical alterations were seen in several brain areas: in frontal and parietal cortices, corpus callosum, thalamus and frontal white matter areas as well as in the cerebellar dentate nucleus. The findings are compatible with neuropsychological findings in FASD. Glial cells seemed to be more affected than neurons. In conclusion, more societal efforts and resources should be focused on recognizing and diagnosing FASD, and supporting subgroups with elevated risk of poor outcome. Without adequate intervention children and adolescents with FASD run a great risk of marginalization and social maladjustment, costly not only to society but also to the lives of the many young people with FASD.

Le travail de l’orthopédagogue quant au dépistage, à la référence et à la prise en charge d’un trouble spécifique d’apprentissage en lecture

Les difficultés reliées à la lecture constituent 80% des motifs de référence en orthopédagogie. Parfois, ces difficultés sont les précurseurs du trouble d’apprentissage le plus commun soit le trouble spécifique d’apprentissage en lecture (TSAL). Cette recherche porte sur le travail des orthopédagogues en lien avec les trois grandes étapes reliées au TSAL : (1) son dépistage, (2) son évaluation orthopédagogique et sa référence en neuropsychologie et finalement (3) sa prise en charge ainsi que sa rééducation en lien avec les recommandations neuropsychologiques. La collecte de données a été réalisée grâce à des entrevues avec trois orthopédagogues travaillant au primaire et autour d’un cas d’élève atteint de TSAL. Chacune des trois orthopédagogues a présenté un cas d’élève et a décrit sa pratique. Lors des rencontres, chaque participante a également remis au chercheur le dossier de l’élève contenant le rapport neuropsychologique confirmant le diagnostic. Les résultats de cette recherche indiquent que les signes précurseurs observés par les trois orthopédagogues ainsi que leurs interventions rééducatives sont très semblables. Toutefois, les outils d’évaluation utilisés diffèrent de l’une à l’autre tant en ce qui a trait au choix qu’à la manière de les utiliser. Les trois orthopédagogues optent pour la référence en neuropsychologie dans le but ultime de dresser un portrait global de leur élève quant à leurs habiletés cognitives et déficitaires pouvant être attribuables à un TSAL. Le rapport du neuropsychologue sert alors à confirmer l’impression diagnostique des orthopédagogues. Les résultats de notre étude montrent que les orthopédagogues entament de façon précoce les interventions rééducatives et offrent simultanément les mesures adaptatives relatives aux difficultés observées chez l’élève. Avec l’arrivée du diagnostic de TSAL, et les recommandations proposées dans le rapport neuropsychologique, les orthopédagogues valident et peuvent à l’occasion bonifier leurs interventions ou mesures. De plus, elles les officialisent en les ajoutant, si ce n’est pas déjà fait, au plan d’intervention de l’élève. Les interventions rééducatives et les mesures adaptées mises en place par les trois orthopédagogues sont également comparées à celles proposées par les neuropsychologues et analysées à la lumière de celles reconnues comme étant efficaces et profitables selon la littérature. Nos résultats mettent en évidence la grande similitude qui existe entre les interventions appliquées par les orthopédagogues, celles proposées par les neuropsychologues ainsi que celles répertoriées dans la littérature.

Desempenho de escolares com distúrbio de aprendizagem e dislexia em testes de processamento auditivo

OBJETIVO: caracterizar e comparar, por meio de testes comportamentais, o processamento auditivo de escolares com diagnóstico interdisciplinar de (I) distúrbio da aprendizagem, (II) dislexia e (III) escolares com bom desempenho acadêmico. MÉTODOS: participaram deste estudo 30 escolares na faixa etária de 8 a 16 anos de idade, de ambos os gêneros, de 2ª a 4ª séries do ensino fundamental, divididos em três grupos: GI composto por 10 escolares com diagnóstico interdisciplinar de distúrbio de aprendizagem, GII: composto por 10 escolares com diagnóstico interdisciplinar de dislexia e GIII composto por 10 escolares sem dificuldades de aprendizagem, pareados segundo gênero e faixa etária com os grupos GI e GII. Foram realizadas avaliação audiológica e de processamento auditivo. RESULTADOS: os escolares de GIII apresentaram desempenho superior nos testes de processamento auditivo em relação aos escolares de GI e GII. GI apresentou desempenho inferior nas habilidades auditivas avaliadas para testes dicóticos de dígitos e dissílabos alternados, logoaudiometria pediátrica, localização sonora, memória verbal e não-verbal, ao passo que GII apresentou as mesmas alterações de GI, com exceção do teste de logoaudiometria pediátrica. CONCLUSÃO: os escolares com transtornos de aprendizagem apresentaram desempenho inferior nos testes de processamento auditivo, sendo que os escolares com distúrbio de aprendizagem apresentaram maior número de habilidades auditivas alteradas, em comparação com os escolares com dislexia, por terem apresentado atenção sustentada reduzida. O grupo de escolares com dislexia apresentou alterações decorrentes da dificuldade relacionada à codificação e decodificação de estímulos sonoros.

Velocardiofacial syndrome with a rare t(2;22)

Rearrangements involving chromosomes 2 and 22 were described not only as acquired abnormalities in a variety of human neoplasias but also in the constitutional karyotype suggesting the existence of a greater fragility in some specific regions in these chromosomes. Patients with DiGeorge and Velocardiofacial syndromes have a deletion on 22q11 leading to haploinsufficiency for one or more gene(s). We report a patient with velocardiofacial syndrome in which cytogenetic and fluorescence in situ hybridization analysis showed a rare t(2;22) and deletion in the 22q11 region. © 2007 Lippincott Williams & Wilkins, Inc.

Potenciais evocados auditivos de longa latência em escolares com transtornos específicos de aprendizagem

Purpose: To study the components of long latency auditory evoked potentials and to compare data from these measures in students with and without learning disabilities. Method: Thirty students, 15 with learning disorder (study group) and 15 typical without learning problems (control group), of both genders, aged 7-14 years, mean age 10 years. They underwent clinical assessment in a clinic belonging to a public university in the state of São Paulo. Following, audiological assessment was performed to determine normal peripheral auditory system and electrophysiological assessment by examining the long latency auditory evoked response. Result: The results showed that there are functional differences between the groups. Increased latency components of long latency auditory evoked potential was observed in the study group compared to the control group. Longer latency values of these components were observed in the left ear when stimulated in the study group. Conclusion: This study contributed to better understanding of the auditory pathway functioning in children with learning disorders and can be a reference for other clinical and experimental studies and thus improve the definition of diagnostic criteria in this population.

Studio di ausili tecnologici compensativi di supporto all'iter di apprendimento matematico secondario e universitario degli studenti con dislessia

Data coming out from various researches carried out over the last years in Italy on the problem of school dispersion in secondary school show that difficulty in studying mathematics is one of the most frequent reasons of discomfort reported by students. Nevertheless, it is definitely unrealistic to think we can do without such knowledge in today society: mathematics is largely taught in secondary school and it is not confined within technical-scientific courses only. It is reasonable to say that, although students may choose academic courses that are, apparently, far away from mathematics, all students will have to come to terms, sooner or later in their life, with this subject. Among the reasons of discomfort given by the study of mathematics, some mention the very nature of this subject and in particular the complex symbolic language through which it is expressed. In fact, mathematics is a multimodal system composed by oral and written verbal texts, symbol expressions, such as formulae and equations, figures and graphs. For this, the study of mathematics represents a real challenge to those who suffer from dyslexia: this is a constitutional condition limiting people performances in relation to the activities of reading and writing and, in particular, to the study of mathematical contents. Here the difficulties in working with verbal and symbolic codes entail, in turn, difficulties in the comprehension of texts from which to deduce operations that, once combined together, would lead to the problem final solution. Information technologies may support this learning disorder effectively. However, these tools have some implementation limits, restricting their use in the study of scientific subjects. Vocal synthesis word processors are currently used to compensate difficulties in reading within the area of classical studies, but they are not used within the area of mathematics. This is because the vocal synthesis (or we should say the screen reader supporting it) is not able to interpret all that is not textual, such as symbols, images and graphs. The DISMATH software, which is the subject of this project, would allow dyslexic users to read technical-scientific documents with the help of a vocal synthesis, to understand the spatial structure of formulae and matrixes, to write documents with a technical-scientific content in a format that is compatible with main scientific editors. The system uses LaTex, a text mathematic language, as mediation system. It is set up as LaTex editor, whose graphic interface, in line with main commercial products, offers some additional specific functions with the capability to support the needs of users who are not able to manage verbal and symbolic codes on their own. LaTex is translated in real time into a standard symbolic language and it is read by vocal synthesis in natural language, in order to increase, through the bimodal representation, the ability to process information. The understanding of the mathematic formula through its reading is made possible by the deconstruction of the formula itself and its “tree” representation, so allowing to identify the logical elements composing it. Users, even without knowing LaTex language, are able to write whatever scientific document they need: in fact the symbolic elements are recalled by proper menus and automatically translated by the software managing the correct syntax. The final aim of the project, therefore, is to implement an editor enabling dyslexic people (but not only them) to manage mathematic formulae effectively, through the integration of different software tools, so allowing a better teacher/learner interaction too.

O saber na perspectiva psicanalítica de orientação freudo-lacaniana: um estudo teórico

This work came from a research question, namely authorizing a child to learn, lifted from the care of a child of 09 years in the school service of a private university located in Natal, whose complaint referred to a learning disorder more specifically, not the formalization of reading and writing. To undertake a survey of the Lacanian psychoanalytic - Freudian literature on learning, we find the concept of knowledge as fundamental to the analysis of this issue which led us to investigate the history of its co nstruction in Freud and Lacan, with a view to shed light on their relationship to learn. This is a theoretical type of research with the proposal to revisit the concept of knowledge in the work of Freud and Lacan's teaching, in which case only served as th e trigger point of this work. We found that in both these authors, the concept of knowledge is associated to the unconscious exclusively and can be hinged to learn the way of the desire to know. It concludes that learning is a process that involves the unconscious knowledge. Consequently, learning disorders may be linked to the impossible into play in the know about the desire to find himself alienated the significant of what operates as forbidden to know when not referred only or also of teaching and / or educational aspects. This shows us that the complaints that come to the clinic can illustrate dilemmas experienced by the speaking, related to subjective questions. Deviations from the possibility of learning may indicate in these cases, a manifestation of what is singular and very impossibility of generalization when it comes to subjects. With this, also attest that the relations of the subject with knowledge effect in learning processes.

Das bildungstheoretische Potenzial inklusiver Pädagogik. Meilensteine der Konstruktion von Bildung und Behinderung am Beispiel von Kindern mit Lernschwierigkeiten

Inklusion erfordert Veränderungen, Umbau und Umdenken auf vielen Ebenen. Ob Teilhabe gelingt, entscheidet sich letztlich im pädagogischen Alltag. So muss in einem inklusiven Bildungssystem auch geklärt werden, was Bildung ausmacht, wenn sie alle Kinder adressiert. Was bedeutet hier Bildung und in welchem Zusammenhang stehen die Konstrukte von Bildung und Behinderung? Wurden doch traditionell die Grenzen des ersten systemwirksam mit der Zuschreibung des zweiten markiert. Das vorliegende Buch thematisiert in historischer Perspektive die sich verändernden Vorstellungen über Bildung, Behinderung(en) und Gerechtigkeit im Bildungssystem sowie die damit verbundenen kontroversen Debatten sowie die häufig uneinheitlichen, teils gegenläufigen Entwicklungen der sogenannten Sonder- und der sogenannten Regelpädagogik. Die Analyse arbeitet die Beiträge integrations- und inklusionspädagogischer Theorien (Reiser, Feuser, Prengel, Wocken, Reich) zu einem gemeinsamen Bildungsverständnis für alle Kinder heraus. Diese Potenziale integrations- und inklusionspädagogischer Theoriebildung werden eingeordnet in bildungstheoretische Dimensionen sowie in die aktuellen Debatten um Inklusion und Bildung als Menschenrecht.
