[Autism and intelligence quotient: stability?]

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.
