Globally, autism spectrum disorder (ASD) affects approximately 1 in 100 children. Ideally, a diagnosis is made with the onset of symptoms before 3 years of age; however, a diagnosis may sometimes be delayed until 6 years or later. There has been an increase in ASD research over the last few decades, with many systematic reviews and meta-analyses synthesizing research evidence for ASD interventions in children. Evidence tends to support the notion that intervention for ASD must occur as early as possible, close to the critical periods when early social and communication skills are developing. Therefore, early screening and intervention could improve the treatment outcomes of individuals with autism, not only helping them survive but to thrive.
