RESUMO

Se han propuesto tres aproximaciones que intentan explicar las peculiaridades del Síndrome de Asperger (SA): disfunción ejecutiva, pobre teoría de la mente o dificultades en la coherencia central. En 2005, Frith y Vignemont proponen una desconexión entre posiciones egocéntrica a alocéntrica, planteando una nueva línea de caracterización del SA. Objetivo: En el presente estudio se comparó el desempeño del tránsito entre posiciones egocéntrica y alocéntrica, en un grupo de cinco niños con SA. Método: El grupo estuvo conformado por 4 niños y 1 niña, con edad promedio de 10 años. Se realizó una valoración detallada a fin de confirmar el diagnóstico y se aplicaron subescalas de la Evaluación Neuropsicológica Infantil. Se reporta el análisis del desempeño en la subescala Habilidades Espaciales. Resultados: Se observa un desempeño dentro del rango promedio observando diferencias estadísticamente significativas entre subdominios que conforman la subescala (014<0.05 F friedman), así como en las respuestas correctas cuando utilizaron marcos de referencia alocéntricos y egocéntrico en tareas de comprensión (gl 2, 0.041<0.05 Q Cochran) y expresión (gl 2, 0.022<0.05 Q Cochran) derecha-izquierda. Conclusión: En el caso del SA, se observa predominio del uso de la posición egocéntrica. El desempeño alocéntrico de los participantes es más eficaz cuando establecen relaciones desde un objeto dinámico vs estático. Se destaca la importancia de realizar un diagnóstico meticuloso del SA, a fin de valorar si las peculiaridades observadas en cognición espacial han sido generalizadas erróneamente a otros Trastornos del Espectro Autista debido a un diagnóstico equivocado.

Asperger Syndrome (SA) has been explained by three approaches: executive dysfunction, impaired theory of mind and central coherence. In 2005, Frith and Vignemont suggest a new approach, based in disconnection between egocentric and allocentric stances. The present study aimed to compare performance´s group of five children with AS in egocentric-allocentric transit task. Four boys and a girl, whose average age was 10 years old, formed the group. A comprehensive assessment confirmed de AS diagnostic. Children were assessed with Evaluacion Neuropsicológica Infantil subtests, and we report the Spatial Abilities subtest analysis. Standard scores were obtained by the group in average values, but there were significant differences (014<0.05 F friedman) between subdomains assessed by Spatial Abilities subtest. We also found significant differences in egocentric-allocentric stances in spatial notion understanding task (gl 2,0.041<0.05 Q Cochran), and spatial notion expression task (gl 2, 0.022<0.05 Q Cochran). Conclusion: AS group prevail taking egocentric stance. Allocentric performance is commonly efficient if individuals take stance from dynamic than static object. We highlight the importance of an accurate and comprehensive assessment in AS diagnosis to avoid generalization of AS features to another Spectrum Autistic Disorders because of a mistaken AS diagnosis.

RESUMO

PURPOSE: To compare the pragmatic profile referring to the communicative initiatives and the bi-dimensional profile involving the aspects of initiative and responsivity. It also aimed to analyze the most common types of responses presented by the studied individuals. METHODS: Thirty recorded samples of interaction between speech-language therapist and children with autism spectrum disorders (mean age: 9 years and 6 months) sessions were analyzed. The samples were transcribed and data analyzed about number of communicative acts, occupation of the communicative space, use of communicative means (verbal, vocal and gestural) and total number of participations (initiatives and responses). The responses were qualified as "non-answer", "adequate answer", "inadequate answer" and "pragmatically inappropriate answer". RESULTS: Significant differences in the comparison of the numbers of initiatives and total participations and of occupation of communicative space and total number of communicative acts. There was also a significant difference in the number of "adequate answers". CONCLUSION: Results show the need to consider the bi-dimensional communicative profile and qualify the answers in order to determine the child's communication abilities.

RESUMO

Attention-deficit/hyperactivity disorder (ADHD) and Asperger's Syndrome (AS) share a heterogeneous cognitive profile. Studies assessing executive functions (EF) and social cognition in both groups have found preserved and impaired performances. These inconsistent findings would be partially explained by the cognitive variability reported in these disorders. First, the present study explored the inter-individual variability in EF and social cognition in both patient groups. Second, we compared differential characteristics and commonalities in the cognitive profiles of EF and social cognition between ADHD, AS and control adults. We assessed 22 patients with ADHD, 23 adults with AS and 21 matched typically developing subjects using different measures of EF (working memory, cognitive flexibility and multitasking) and social cognition (theory of mind and decision-making). Group comparisons and multiple case series analyses (MCSA) were conducted. The between-group comparisons showed an EF deficit in working memory in ADHD and a theory of mind (ToM) impairment in AS. The MCSA evidenced that, compared to controls, ADHD patients had a higher inter-individual variability in EF, while individuals with AS had a more heterogeneous profile in social cognition tasks compared to both groups. Finally, the AS and ADHD groups presented higher task-related variability compared to controls and shared a common heterogeneous profile in EF. This is the first study to compare variability in EF and social cognition profiles of ADHD and AS. We propose that heterogeneity in EF performance is a link between ADHD and AS which may explain the overlap of symptomatology between both diagnoses. In addition, patients with AS seem to show a unique heterogeneous profile in ToM which may explain the low probability of finding AS symptoms in patients with ADHD.

RESUMO

OBJETIVO: Comparar o perfil pragmático das iniciativas de comunicação e o perfil bidimensional envolvendo os aspectos de iniciativa e responsividade. Além disso, buscou-se analisar os tipos mais comuns de resposta apresentadas pelos indivíduos pesquisados. MÉTODOS: Foram analisadas trinta gravações de terapia fonoaudiológica, nas quais as terapeutas interagiam com crianças do espectro do autismo (média de idade: 9 anos e 6 meses). As filmagens foram transcritas e os dados derivados foram analisados quanto ao número de atos comunicativos, à ocupação do espaço comunicativo e ao uso dos meios verbal, vocal e gestual nas iniciativas e no total de participações (iniciativas e respostas). As respostas apresentadas foram qualificadas como: não resposta, resposta adequada, resposta inadequada e resposta pragmaticamente inapropriada. RESULTADOS: Houve diferença na comparação entre as iniciativas e o total de participações no que concerne à ocupação do espaço comunicativo e no total de atos. Quanto às respostas, houve diferença no número de respostas adequadas. CONCLUSÃO: Os resultados evidenciaram a necessidade de considerar o perfil bidimensional de comunicação e ressaltaram a necessidade de qualificar as respostas a fim de discriminar as habilidades comunicativas da criança.

RESUMO

Over the last years, increasing evidence has fuelled the hypothesis that Autism Spectrum Disorder (ASD) is a condition of altered brain functional connectivity. The great majority of these empirical studies relies on functional magnetic resonance imaging (fMRI) which has a relatively poor temporal resolution. Only a handful of studies has examined networks emerging from dynamic coherence at the millisecond resolution and there are no investigations of coherence at the lowest frequencies in the power spectrum-which has recently been shown to reflect long-range cortico-cortical connections. Here we used electroencephalography (EEG) to assess dynamic brain connectivity in ASD focusing in the low-frequency (delta) range. We found that connectivity patterns were distinct in ASD and control populations and reflected a double dissociation: ASD subjects lacked long-range connections, with a most prominent deficit in fronto-occipital connections. Conversely, individuals with ASD showed increased short-range connections in lateral-frontal electrodes. This effect between categories showed a consistent parametric dependency: as ASD severity increased, short-range coherence was more pronounced and long-range coherence decreased. Theoretical arguments have been proposed arguing that distinct patterns of connectivity may result in networks with different efficiency in transmission of information. We show that the networks in ASD subjects have less Clustering coefficient, greater Characteristic Path Length than controls - indicating that the topology of the network departs from small-world behaviour - and greater modularity. Together these results show that delta-band coherence reveal qualitative and quantitative aspects associated with ASD pathology.

RESUMO

UNLABELLED: Individuals with psychiatric disorders can present perception, attention and memory deficits, raising doubts about peripheral and/or central hearing loss. Thus, the aim of this study is to describe the audiological and electrophysiological results of individuals with psychiatric disorders, looking for peripheral and/or central auditory disorders. METHODS: 20 individuals with autism and Asperger syndrome and 20 individuals without psychiatric disorders from eight to 19 years of age, were submitted to audiological and electrophysiological evaluation. RESULTS: No alterations were observed on the audiological evaluation in all the individuals. In ABR, 50% of individuals with autism and 30% with Asperger syndrome presented alterations. Significant statistical differences were observed between the groups in the quantitative analysis. All groups presented alterations in AMLR and P300. In AMLR, no significant statistical differences were observed between the groups in the qualitative and quantitative analyses. In the P300, we noticed significant statistical differences between Asperger and control groups in the quantitative analysis. CONCLUSIONS: A high occurrence of alterations in auditory evoked potentials was seen in children with psychiatric disorders, although in some analysis it was observed a non-statistically significant difference when comparing study and control groups. We stress the need for a more careful investigation of the auditory function in this population.

RESUMO

Indivíduos com transtornos psiquiátricos podem apresentar distúrbios perceptuais, de atenção e memória, questionando-se a presença de perdas auditivas periféricas e/ou centrais. Assim, o objetivo deste trabalho é descrever os resultados obtidos nas avaliações audiológica e eletrofisiológica, verificando a ocorrência de alterações auditivas periféricas e/ou centrais nesta população. Casuística e Métodos: Foram avaliados 20 indivíduos com autismo e síndrome de Asperger, e 20 indivíduos em desenvolvimento típico, entre oito e 19 anos. Resultados: Todos os indivíduos apresentaram resultados normais na avaliação audiológica. No PEATE, 50% dos indivíduos com autismo e 30% com síndrome de Asperger apresentaram alterações, havendo diferença estatisticamente significante na análise dos dados quantitativos em ambos os grupos. Em todos os grupos verificaram-se alterações no PEAML e P300. No PEAML, não houve diferençaestatisticamente significante entre os grupos na análise dos dados quantitativos e qualitativos. No P300, observou-se diferença estatisticamente significante quando comparados os grupos controle e síndrome de Asperger na análise dos dados quantitativos. Conclusão: Verificou-se grande ocorrência de alterações nos potenciais evocados auditivos em crianças autistas e com síndrome de Asperger, embora em algumas análises realizadas não tenha sido constatada diferença estatisticamente significante. Enfatiza-se a importância da investigação minuciosa da função auditiva em indivíduos com transtornos psiquiátricos.

RESUMO

INTRODUCTION: Asperger's syndrome (AS) is characterised by its effects on reciprocal social interaction, verbal and non-verbal communication, difficulty in accepting changes, inflexible thinking and reduced fields of interest, but also by the presentation of special skills. DEVELOPMENT: On the occasion of the centenary of the birth of Hans Asperger, we briefly review the history of this researcher and offer a short description of the clinical features of the condition, including social interaction, communication, limited concerns and interests, routines and inflexibility, which are key points when it comes to reaching a diagnosis. Later, we also focus on Savant syndrome, which is a very common subgroup within AS and which is characterised by the patient's outstanding ability is certain special skills, such as hypermnesia, hyperlexia and hypercalculia, in mental feats concerning the perpetual calendar and in several branches of the arts, such as drawing, painting, sculpture and music. We discuss several famous cases of savants and explain some of the theories about its pathophysiology. CONCLUSIONS: Having special skills is a distinguishing mark of AS and identifying and facilitating them would provide us with a potential tool with which to accomplish suitable job opportunities.

RESUMO

With the aim of analyzing which complementary tests are relevant in the diagnostic evaluation of individuals with pervasive developmental disorders, a protocol of clinical and laboratory evaluation was applied in 103 outpatients. The protocol included chromosomal analysis, screening for inborn errors of metabolism, cytogenetic and molecular study of the FRAXA, FRAXE, and FRAXF mutations, EEG, SPECT, and magnetic resonance imaging study. Eighty-four subjects concluded the complementary tests and were classified either as having autism, atypical autism or Asperger syndrome according to the DSM-IV criteria. Sixteen individuals, all bellonging to the two autistic groups, presented genetic or enviromental factors that may have lead to the behavioral disorders, showing the importance of diagnostic evaluation in this group of conditions. Neuroimaging and EEG findings were non-specific and occurred in similar proportion among the groups, being considered of relative low significance in the diagnostic evaluation of individuals with pervasive developmental disorders.
