Autism Spectrum Disorder

Abstract

Screening for early signs of autism spectrum disorder (ASD) (before 36 months of age) allows an early diagnosis and early intervention programs that provide better developmental opportunities for the child. The objective of this chapter is to increase the knowledge about early signs of ASD enabling their early detection. The method used was a literature review of the early warning signs of autism spectrum disorder in children between 24 and 36 months of age in the domains that characterize this disorder.
