Abstract

Introduction: Autism is a heterogeneous disorder. The possibility of determining its characteristics over time will have a great impact on the prognosis and predictions that can be made. In that regard, the intelligence quotient and its possible stability throughout the life cycle can help to better define the phenotype of the disorder and its associated needs.

Development: Longitudinal studies show a certain level of stability in intelligence quotient scores, especially starting from the school years. Before, in the preschool stage, there is greater variability, especially in those children who have a borderline intellectual functioning or moderate intellectual disability.

Conclusion: More research should continue to be developed to know the cognitive profile of people with autism spectrum disorder and be able to make predictions based on their intellectual functioning.

Title: Autismo y cociente intelectual: estabilidad?

Introduccion. El autismo es un trastorno heterogeneo. La posibilidad de determinar sus caracteristicas a lo largo del tiempo tendra una gran repercusion en el pronostico y las predicciones que se puedan hacer. En ese sentido, el cociente intelectual y su posible estabilidad a lo largo del ciclo vital pueden ayudar a definir mejor el fenotipo del trastorno y sus necesidades asociadas. Desarrollo. Los estudios longitudinales muestran cierta estabilidad en las puntuaciones del cociente intelectual, sobre todo a partir de los años escolares. Antes, en la etapa preescolar, existe mayor variabilidad, especialmente en aquellos niños que tienen un funcionamiento intelectual limite o discapacidad intelectual moderada. Conclusion. Debe seguirse desarrollando mas investigacion para conocer el perfil cognitivo de las personas con trastorno del espectro autista y poder realizar predicciones a partir de su funcionamiento intelectual.
