Abstract
The criteria that subsidized the diagnosis of autism have undergone several changes over the years, following the hegemonic conceptual assumptions of the period. This study analyzed the evolution of the diagnosis of autism during the 21st century with use of the domains and subdomains that served as basis for nosological categorizations. Additionally, the auxiliary instruments used, some diagnostic technologies under development, and conceptual models that address neuropsychological profiles are presented. This documentary research utilized diagnostic manuals of the period. The domains of social interaction, communication, and restricted and repetitive behavior patterns were maintained in the different diagnostic manuals addressed. The subdomains of social interaction and communication were reduced, while restricted and repetitive pattern was consolidated in DSM-5. Understanding the evolution of diagnostic criteria tends to promote clinical development, potentiating the anticipation of the diagnosis and the interventions necessary for a better prognosis.
