Este estudo piloto apresenta resultados preliminares relativos à prevalência de autismo na América do Sul. A definição de caso foi baseada em uma combinação de instrumentos padronizados e avaliações clínicas por especialistas. A prevalência de autismo foi de 27,2 / 10.000 (IC 95%: 17,6–36,8) e algumas hipóteses foram levantadas para explicar essa baixa frequência. O estudo levantou preocupações sobre o tratamento dos casos, porque a identificação do TID foi tardia e o acesso aos serviços foi muito limitado.

Resumo:
This pilot study presents preliminary results concerning the prevalence of Pervasive Developmental
Disorder (PDD) in South America. It was a three-phase study conducted in a typical town in Southeast Brazil. Case definition was based in a combination of standardized instruments and clinical evaluations by experts. The prevalence of PDD was 27.2/10,000 (95% CI: 17.6–36.8) and some hypotheses were raised to explain this low frequency. Clinical findings of PDD cases were consistent with previous data, such as, male preponderance, more children diagnosed with PDD-NOS than with autistic disorder, and
half of them born from older mothers. Moreover, the study raised concerns about treatment of cases, because identification of PDD had been late and access to services has been very limited.
