The majority of children diagnosed with ASD live in low- and middle-income countries (LMICs). There is, however, inadequate understanding of the prevalence, screening, diagnosis and treatment for these children in LMICs. As most of the current evidence comes from high-income countries, this narrative review will focus specifically on children with ASD living in Sri Lanka, a lower-middle-income country. It will discuss the prevalence of ASD, current screening and diagnostic assessments, and services available for these children, with a focus on speech therapy and augmentative and alternative communication (AAC).
