Etiological Factors of Autism Spectrum Disorder

People with autism spectrum disorder (ASD) have multifactorial etiology, combined by different factors, both genetic, psychological and environmental; however, it´s necessary sharply discriminate those significant factors or components, regarding elaborate an early action protocol for diagnostic processes and subsequent intervention guidelines, which co A total of 192 participants with ASD of three intensity levels (American Psychiatric Association -APA-, 2013) have collaborated in this study. ASD diagnostic shape the discrimination´ aim to 18 independent variables, considered, a priori, potentially influential over diagnostic intrinsic process. Results of discriminant analysis include two axes it delimits the two main functions, represented by two variables: "karyotype" (Wilks´ Lambda statistic= .88) and "diagnosis" (Wilks´ Lambda statistic= .83). Both variables are complemented along structure matrix of discriminant analysis with variable "gene" for first function ("karyotype") and variable "age" to second function ("diagnosis" + "karyotype"). These allow defining the general characteristics to establish an effective action protocol for the specific diagnosis, which constitutes the general aim of this empirical research.
