The aim was to examine to what extent the dimensions of the BPS map the five factors derived from the PANSS in order to explore the level of agreement of these alternative dimensional approaches in patients with schizophrenia. 149 inpatients with schizophrenia spectrum disorders were recruited. Psychopathological symptoms were assessed with the Bern Psychopathology Scale (BPS) and the Positive and Negative Syndrome Scale (PANSS). Linear regression analyses were conducted to explore the association between the factors and the items of the BPS. The robustness of patterns was evaluated. An understandable overlap of both approaches was found for positive and negative symptoms and excitement. The PANSS positive factor was associated with symptoms of the affect domain in terms of both inhibition and disinhibition, the PANSS negative factor with symptoms of all three domains of the BPS as an inhibition and the PANSS excitement factor with an inhibition of the affect domain and a disinhibition of the language and motor domains. The results show that here is only a partial overlap between the system-specific approach of the BPS and the five-factor PANSS model. A longitudinal assessment of psychopathological symptoms would therefore be of interest.

La medicina y la ingeniería del siglo XXI han dado como fruto numerosos avances para la sociedad aunque en la mayoría de los casos los tratamientos suelen ser costosos e invasivos. La educación que recibe la sociedad sobre la salud es escasa, ya que sólo vamos al médico cuando realmente estamos enfermos. Este trabajo presenta nuestra apuesta por las terapias complementarias, para el desarrollo de una metodología terapéutica no invasiva y con un costo muy bajo. La finalidad de esta Tesis, que se enmarca en un equipo multidisciplinar, fruto de la estrecha colaboración en el que participan psicopedagogos, ingenieros y médicos, es perfilar una metodología que luego pueda ser aplicable a patologías neurológicas. Aquí, dejamos sentadas las bases. Faltarán nuevos investigadores que continúen este camino para tener una base de datos lo suficientemente extensa de registros de sujetos que hayan sido sometidos a terapia binaural, para poder sacar unas conclusiones sólidas. La aportación de esta Tesis deja cubierta la aplicación, selección, procesado de señal y desarrollo de algoritmos, test cognitivos indicados para el caso específico que nos ocupa, cálculo de incertidumbre del sistema utilizado para la aplicación del estímulo y desarrollo de un test psicoacústico específico. EL empleo del sonido en medicina como es la musicoterapia o sonoterapia ha experimentado una gran difusión en los últimos años, más de 100.000 nuevas citas bibliográficas han aparecido con respecto al año anterior. Sin embargo, son escasísimas las que hacen referencia a las características físico acústicas del sonido empleado, tan sólo hemos encontrado una par de ellas que correlacionan las características físicas del sonido con el tipo de respuesta terapéutica. No encontramos citas bibliográficas específicas que planteen un modelo experimental científico capaz de reproducir las mismas respuestas ante los mismos parámetros y estímulos. En esta Tesis proponemos el uso de estimulación sonora binaural, que consiste en la utilización de dos tonos puros idénticos pero ligeramente diferentes en frecuencia que se presentan de manera separada cada uno en un oído, como consecuencia, la persona que recibe la estimulación percibe un tercer tono, llamado tono binaural, formado por la diferencia de frecuencia de ambos variando su amplitud. Existen estudios que sugieren que dichas frecuencias binaurales pueden modificar los patrones eléctricos de la actividad cerebral y los niveles de arousal, conociéndose en la literatura bajo el nombre de “entrainment”. Tras la revisión bibliográfica del estado del arte, podemos concluir que es necesario el desarrollo de estudios doble ciego bien diseñados, con el objetivo de establecer una base sólida sobre los efectos de este tipo de estimulación, ya que la mayoría de los beneficios documentados se refieren a muestras muy pequeñas y con poco rigor científico, siendo los resultados positivos obtenidos debidos al efecto placebo. La tecnología binaural es barata siendo cualquier avance en esta dirección de interés público. El objetivo concreto de la investigación es estudiar el potencial de las ondas binaurales en un área en particular: tareas que requieren atención y concentración. Se busca obtener cualquier cambio en las ondas cerebrales que se puedan correlar con la mejoras. A la vista de los resultados de estas investigaciones se intentará aplicar esta metodología en neuropatologías que presenten alguna deficiencia en el área de atención como es el Trastorno de espectro Autista. En esta Tesis presentamos los resultados de dos estudios independientes, el primero para sentar las bases del método (tiempos, diseño de estimulaciones, procesado) en una muestra de 78 adultos sanos, el segundo a partir de los resultados obtenidos en el primero, afinando la metodología y para un grupo de 20 niños entre 8 y 12 años, los resultados del segundo estudio sirven para justificar su aplicación en niños con TEA que presenten déficit de atención. ABSTRACT Medicine and engineering in the 21st century have resulted in advances for society but in most cases the treatments are often costly and invasive. The health education society receive is scarce, since only go to the doctor when we are really sick. With this work I present my commitment to complementary therapies, my little grain of sand in the development of a noninvasive therapeutic approach and very low cost, well and can be used in a preventive manner resulting in a society with less sick. The purpose of this thesis is to outline a methodology that can then be applied to neurological diseases, here we lay the groundwork. New researchers are needed to continue this path for a sufficiently extensive records database of subjects who have undergone binaural therapy, and so to draw firm conclusions. The contribution of this thesis includes: the application, selection, signal processing and algorithm development, indicated cognitive tests for the specific case at hand, calculation of system uncertainty of the system and development of a specific psychoacoustic test. The use of sound in medicine, such as music therapy or sound therapy has experienced a great diffusion in recent years, more than 100,000 new citations have appeared over the previous year but very few are those referring to acoustic physical characteristics of sound employee, we have only found a couple of them that physical sound characteristics are correlated with the therapeutic response. We found no specific citations posing a scientific experimental model capable of reproducing the same answers to the same parameters and stimuli. In this thesis we propose the use of binaural sound stimulation which involves the use of two identical but slightly different in frequency pure tones presented separately each in one ear, as a result the subject perceives a third tone, called binaural tone, formed by the difference in frequency with amplitude variations Studies suggest that these binaural frequencies can modify the electrical patterns of brain activity and arousal levels, being known in the literature under the name of “entrainment”. After the literature review of the state of the art, we conclude, it is necessary to develop well-designed double-blind studies, in order to establish a solid foundation on the effects of such stimulation, since most of the documented benefits relate to very small samples and unscientific may be obtained positive results due to the placebo effect. The binaural technology is cheap being any progress in this direction in the public interest. The specific objective of the research is to study the potential of binaural waves in a particular area: tasks requiring attention and concentration also we want to get any change in brain waves that can correlate with improvements. In view of the results of this research we seek to apply this methodology in neuropathology presenting any deficiency in the area of attention such as Autism Spectrum Disorder. In this thesis we present the results of two independent studies, the first to lay the foundation of the method (times, stimulation design, processing) in a sample of 78 healthy adults, the second from the results obtained in the first, refine the methodology for a group of 20 children between 8 and 12 years, the results of the second study used to justify its use in children with ASD that present attention deficit.

O Transtorno do Espectro do Autismo (TEA) inclui um conjunto de sintomas, tais como dificuldade para sustentar contato visual direto e comprometimento da linguagem. Apesar da Terapia Assistida Por Animais (TAA) com cães ser considerada uma modalidade terapêutica eficaz para promover o desenvolvimento de pessoas com TEA, ainda não são se sabe quais características dos cães possibilitam alcançar sucesso na terapia. Esta análise quantitativa tem como objetivo verificar o impacto de abordagens laterais e frontais de cães e humanos nas expressões emocionais de alegria e rejeição de crianças com TEA. Através da análise de vídeos de TAA, foram mensuradas duração e frequência das abordagens laterais e frontais de cães e humanos dirigidas às crianças para comparar possíveis diferenças entre ambos e também para verificar se a abordagem escolhida afetava o tipo de expressão emocional exibida pela criança. Os participantes deste projeto foram 11 crianças, 8 do sexo masculino e 3 do sexo feminino, entre 5 e 11 anos. Seis crianças foram atendidas por uma psicóloga, uma condutora e um Border Collie. O segundo grupo era composto pela mesma psicóloga, uma condutora e uma Golden Retriever. Escalas de avaliação foram aplicadas para confirmar o diagnóstico de TEA. Os cães foram previamente avaliados e treinados por uma instituição que atua na área de TAA. Cinco minutos de 8 sessões foram analisadas: um bloco de seis sessões com o cão, uma sessão anterior e uma sessão posterior a este bloco. Para verificar possíveis diferenças temperamentais entre cães, o C-barq (Canine Behavioral Assesment & Research Questionnaire) foi aplicado para analisar o temperamento de ambos. Embora esta análise tenha demonstrado diferenças em relação às categorias busca de atenção e nível de energia dos cães, não foram verificadas diferenças estatísticas entre os cães, em relação às variáveis analisadas neste estudo. Na comparação entre cães e humanos, os cães foram mais efetivos para conseguir expressões de alegria independentemente do tipo de abordagem escolhida. Comparando-se o tempo de abordagem de cães e humanos até obterem expressão emocional das crianças, observou-se uma importante diferença estatística. Os resultados sugerem que os cães exibiram menor latência que humanos para todas expressões emocionais analisadas: alegria (2= 7,312, p=0,007), de rejeição (2= 11,277, p-0,001) e neutras (2=9,097, p=0,043). Além disso, os resultados sugerem que, no contexto da TAA, não há relação entre abordagem lateral ou frontal e expressões de alegria, rejeição ou neutras de crianças com TEA. As expressões de alegria foram mais frequentes diante das abordagens laterais dos cães do que das abordagens frontais, no entanto não foi verificada significância estatística. Em relação aos humanos também não foi verificada preferência por uma abordagem especifica. Assim, os resultados sugerem que a latência para a exibição de uma expressão emocional das crianças depende mais de quem aborda do que do posicionamento lateral ou frontal quando a abordagem é realizada

La productividad científica en Síndrome de Asperger (SA) se ha incrementado considerablemente en los últimos años desde distintos campos de la Educación y la Psicología. Incluido dentro de los Trastornos del Espectro del Autismo según el DSM-5, el SA se caracteriza por una alteración en las capacidades de relación social, comunicación y flexibilidad mental. Es objeto del presente estudio ofrecer una revisión del estado actual de la investigación en dicho ámbito e identificar las principales aportaciones científicas. La unidad de análisis se compuso por 1741 documentos extraídos de la Social Science Citation Index y revisados minuciosamente. Los resultados evidenciaron un incremento de la productividad temporal y el interés científico en las áreas de caracterización del SA, comorbilidad y tratamiento. Además, se observó una tendencia a realizar los trabajos en colaboración y un número considerable de autores clasificados como grandes productores por sus niveles de productividad superiores a los diez trabajos. La funcionalidad de esta revisión se encuentra en su valor como material de referencia para futuras líneas de investigación en tanto que abarca la identificación y análisis de los principales campos de estudio en este ámbito.

Un certain nombre de chercheurs (Birch, 1996; Cole, 1995, 1996; De Bergerac, 1998) fondent sur un modèle neurophysiologique leurs arguments en faveur de la delphinothérapie pour traiter divers désordres (DSM-IV) cognitifs et émotifs chez les enfants et les jeunes. Ce modèle recourt à des analogies avec les mécanismes de sonophorèse, d'écholocation et de transmission neurohormonale dans son application thérapeutique. Dans le but de démystifier les éléments pseudo-scientifiques auprès d'un lectorat non spécialisé, cet article critique les postulats et les implications relatifs à ces mécanismes et il conclut à l'absence d'un soutien pertinent et valide concernant ce modèle.

Community paediatrics strives to integrate the biology of health into the social and psychological worlds within which children grow and develop. Consumer demand for limited community paediatric clinical services is increasing and medico-legal pressures escalate professional and personal concern. Meanwhile, the profession, through training and professional support, has struggled to keep up. Research into community paediatrics and its integration into policy and clinical practice remains limited, raising the perception that it is a 'soft' science. Our viewpoint is that necessary progress in this field requires leadership, apprenticeship and research. We argue that to build firm foundations for the future requires structures to enable clinical specialisation and continuing professional development in this area.

The presence of students with Autism Spectrum Disorder (ASD) in regular schools has increased and with it, the need to develop interventional strategies that enhance their learning. One of the tools that can facilitate this process is Mediated Learning, defined as an interaction style where the teacher selects, modifies, enhances, and interprets environmental stimuli in order to promote student learning. In recent years several studies have used the Mediated Learning Experience Scale (MLE; Lidz, 1991) as a tool to assess the mediator behavior. These studies have suggested that the EAM Scale can provide important guidelines for planning educational interventions, particularly those involving students with special needs. In order to extend these findings, this study aimed to evaluate the effects of an intervention based on the Mediated Learning Experience on social / academic skills of a child with ASD, enrolled in the 4th grade of a regular elementary school. This collaborative study was held in the city of Parnamirim, state of Rio Grande do Norte, in 2014. A 9-year old boy with ASD and his teacher participated in the study. The research used a quasi-experimental A-B design (baseline and treatment) to evaluate the teacher's behavior. Qualitative procedures were also used to analyze the dyad´s responses. Teacher and student behaviors were observed in three school routines during baseline. Based on the results of this phase, a training program was designed for the teacher. Dyad behavior was analyzed again after training in the same routines. The results of this phase showed qualitative and quantitative changes in levels of teacher mediation. Additionally, data indicated that the child enhanced his social and academic skills during the intervention.

Background/aims: Objective of the current thesis is to investigate the potential impact of birth by Caesarean section (CS) on child psychological development, including autism spectrum disorder (ASD), attention-deficit/hyperactivity disorder (ADHD), behavioural difficulties and school performance. Structure/methods: Published literature to date on birth by CS, ASD and ADHD was reviewed (Chapter 2). Data from the UK Millennium Cohort Study (MCS) were analysed to determine the association between CS and ASD, ADHD and parent-reported behavioural difficulties (Chapter 3). The Swedish National Registers were used to further assess the association with ASD, ADHD and school performance (Chapters 4-6). Results: In the review, children born by CS were 23% more likely to be diagnosed with ASD after controlling for potential confounders. Only two studies reported adjusted estimates on the association between birth by CS and ADHD, results were conflicting and limited. CS was not associated with ASD, ADHD or behavioural difficulties in the UK MCS. In the Swedish National Registers, children born by CS were more likely to be diagnosed with ASD or ADHD. The association with elective CS did not persist when compared amongst siblings. There was little evidence of an association between birth by elective CS and poor school performance. Children born by elective CS had slight reduction in school performance. Conclusions: The lack of association with the elective CS in the sibling design studies indicates that the association in the population is most probably due to confounding. A small but significant association was found between birth by CS and school performance. However, the effect may have been due to residual confounding or confounding by indication and should be interpreted with caution. The overall conclusion is that birth by CS does not appear to have a causal relationship with the aspects of child psychological development investigated.

Notre système visuel extrait d'ordinaire l'information en basses fréquences spatiales (FS) avant celles en hautes FS. L'information globale extraite tôt peut ainsi activer des hypothèses sur l'identité de l'objet et guider l'extraction d'information plus fine spécifique par la suite. Dans les troubles du spectre autistique (TSA), toutefois, la perception des FS est atypique. De plus, la perception des individus atteints de TSA semble être moins influencée par leurs a priori et connaissances antérieures. Dans l'étude décrite dans le corps de ce mémoire, nous avions pour but de vérifier si l'a priori de traiter l'information des basses aux hautes FS était présent chez les individus atteints de TSA. Nous avons comparé le décours temporel de l'utilisation des FS chez des sujets neurotypiques et atteints de TSA en échantillonnant aléatoirement et exhaustivement l'espace temps x FS. Les sujets neurotypiques extrayaient les basses FS avant les plus hautes: nous avons ainsi pu répliquer le résultat de plusieurs études antérieures, tout en le caractérisant avec plus de précision que jamais auparavant. Les sujets atteints de TSA, quant à eux, extrayaient toutes les FS utiles, basses et hautes, dès le début, indiquant qu'ils ne possédaient pas l'a priori présent chez les neurotypiques. Il semblerait ainsi que les individus atteints de TSA extraient les FS de manière purement ascendante, l'extraction n'étant pas guidée par l'activation d'hypothèses.

Ce mémoire présente et discute d’une problématique importante qui s’inscrit dans un contexte actuel, autant sur le plan international que local, puisqu’elle touche 1 enfant sur 68 (CDC, 2010). On parle ici du trouble du spectre de l’autisme (TSA). Plus spécifiquement, cette recherche se concentre sur les jeunes adultes autistes, qui du jour au lendemain, se retrouvent face à une interruption de services. Elle suggère qu’une adaptation adéquate de l’environnement soit davantage explorée en vue d’offrir des centres de jour adaptés à cette clientèle. La question de recherche est la suivante : Quels sont les éléments du design intérieur qui peuvent améliorer la qualité de vie des adultes autistes? Il est essentiel de s’y attarder, puisque les personnes TSA sont entre autres caractérisées par leur hypersensibilité et leur hyposensibilité face à l’environnement. Bien que le sujet de l’autisme soit richement documenté par le domaine des sciences médicales, il est apparu qu’il l’est moins par celui de l’aménagement. La stratégie méthodologique de cette recherche repose sur des analyses de précédents, des observations participantes ainsi que la tenue d’entretiens semi-dirigés auprès de parents d’enfants autistes. Cette étude vise simultanément l’amélioration de la compréhension de la pratique émergente du design comme moyen d’intervention ainsi que l’identification des facteurs (éclairages, couleurs, matériaux, division de l’espace, etc.) pouvant améliorer le bien-être des adultes autistes. Sur la base des données collectées, il a été remarqué qu’effectivement, plusieurs moyens peuvent être entrepris pour concevoir des environnements améliorant le bien-être de ces adultes. Les résultats extraits du terrain mènent à des propositions d’aménagement claires : rendre l’abstrait le plus concret possible, aménager des zones de retrait social, offrir une variété d’ambiances, et finalement, offrir un encadrement sécuritaire.
