ABSTRACT

The conceptual evolution of autism spectrum disorder (ASD) from a propositional configuration is defined as a multilateral process of neurodevelopment, based on a particular process determined by the presence of pyramidal neurons, which show a dendritic increase of alterations in the system of neuronal connections, which form a regulatory network of pyramidal glutamatergic activity. The etiology is basically due to multiple possible genetic mutations or environmental processes which, in turn, may cause specific neuronal remodeling, determined by certain psycho-organic conditions, whose consequences are observed in the GABAergic cerebral connexional pathways.

The scope of this study is to verify the significance of factorial clustering that directly or indirectly affect the genetic mutation process as an explanatory basis for the etiology of autism spectrum disorder and, consequently, to be able to establish major empirical predictions about the presence of this disorder associated cluster.

A total of 116 participants with autism have collaborated in this study, elaborated from the factorial dimensional reduction of the independent variables, which have been factorially reduced to two factors: "Disease" and "GENETIC", as explanatory dimensions of the etiology of the autistic disorder formed by the variable "level" (levels 1-2-3) (American Psychiatric Association [APA], 2013) of the disorder. The study forms the analysis of groupings of belonging of the cases, according to the parametric statistical technique of hierarchical clustering through the Ward method, contrasted by means of an ordinal regression analysis of the logit link in order to elaborate the grouping of cases according to their particularities, which are corroborated by an ordinal regression analysis according to the logit calculation for the basic conceptual variable that configures the current neuropsychological development of autism, in relation to the capacity of elaboration of neural networks or nodes during information processing, which has been operationalized with the name of "nodes". Finally, comparative t-studies of the findings in both factors in relation to the variables sex and age of the participants were carried out.

The results concluded with the configuration of three differential clusters, which have been corroborated by a one-factor ANOVA analysis, which has indicated significant critical levels for the two factors (sig: .00). The contrasts of the ordinal regression analysis corroborated the goodness of fit of the factors as explanatory components of the etiology of the disorder (sig: .00), which have been duly corroborated by the ordinal regression analysis for these same etiological factors and the consequent statistical process of neural networks by means of the multilayer perceptron procedure. Likewise, no significant differential comparative levels have been observed in the predictive results referring to the levels of the explanatory variance of the etiology of the diagnosis of autism as a function of the variables sex and age.

Abstract

At currently, developments regarding to autism spectrum disorder have enabled its diagnostic group to be defined as a multilateral neurodevelopmental disorder characterised by peculiarities in the procedural functioning of perceptual-cognitive parameters, derived from a characteristic connexional form in the pathway of interconnection between intrinsic information and contextual stimuli. In this characteristic process, neuronal networks are involved a fundamental processing task for working memory to be able to perform the set of executive functions with a certain degree of stability, which is severely limited in people diagnosed with this disorder. In this study, the reports of 403 participants diagnosed with the disorder were analysed with the following basic goals: 1) to analyse the relationship between relational deficits and the elaboration of semantic content, 2) to analyse the etiological attribution of the GABAergic pathway responsible for the limitations in these connections and, consequently, 3) to conclude the main predictive-explanatory level of this disorder. The data have been found by means of different statistical tests, both initial correlational tests, statistical calculation processes, univariate one-factor ANOVA tests and final consequential ordinal multinomial logit regression tests. Data found allow us to delimit that the regression equation of the model fitting information explaining the disorder shows a final logit model chi-square: 217.23, with a significant associated critical level (sig: .00), which are complemented by the significantly positive Pearson and Deviance data significantly related to the logit level (sig: .00), which confirms the importance of the predictive-explicative level of the neuronal and semantic variables derived from the GABAergic limitations in order to be able to be converted into the main propositional components of autism as a highly related neurocognitive systemic process.

Trastorno del espectro autista: rompiendo muros:

El libro titulado Trastorno del espectro autista: rompiendo muros comprende un relato biográfico-etnográfico enmarcado dentro de los análisis de investigación empíricos de los estudios de caso y realizado a lo largo de treinta y dos años de la evolución vital de Cristian (nombre ficticio).
Para facilitar la comprensión del manual, su desarrollo longitudinal ha sido estructurado en cinco intervalos evolutivos, correspondientes a la edad de Cristian: 1) 0-4.5 años, 2) 4.6-9 años, 3) 9.1-12 años, 4) 12.1-16.5 años y 5) 16.6-32 años. Para cada uno de los intervalos de edad indicados, se han analizado exhaustivamente
dos dimensiones específicas básicas, cada una de las cuales comprende el desarrollo de cinco subdimensiones o componentes principales de estudio, que conforman el funcionamiento neuropsicológico de la información del desarrollo humano, más específicamente centrado en las hipótesis del procesamiento de las personas con
autismo: I) la dimensión evolutivo-conductual: 1) el desarrollo del lenguaje, 2) el tipo de comunicación social, 3) el análisis de la interacción social, 4) el estudio de los comportamientos restrictivos y 5) el análisis de los comportamientos estereotipados; y II) la dimensión perceptivo-cognitiva: 1) el análisis de la atención-ercepción, 2) el estudio del proceso de codificación conductual, 3) el análisis de la creación de categorías, 4) el estudio de las relaciones nodales neuropsicológicas y 5) el estudio de la capacidad de elaboración y recuperación de la información existente en la memoria semántica.
El estudio ha sido complementado con un análisis comparativo perceptivocognitivo entre personas pertenecientes al grupo diagnóstico del autismo en relación con personas neurotípicas, lo cual ha permitido concluir con la elaboración de una nueva teoría conceptual que conforma el procedimiento perceptivo-cognitivo altamente específico de las personas con autismo, denominado teoría cíclica global (TCG) o teoría proposicional perceptivo-cognitiva.
El libro pone de manifiesto que un diagnóstico específico aparantemente claro en las primeras fases del desarrollo de Cristian habría sido un grave error ya en la tercera fase de su desarrollo si solo se tienen en cuenta los criterios evolutivo- conductuales de las clasificaciones actuales, lo cual permite construir nuevas teorías proposicionales sobre el concepto del autismo.
