title: The status of early identification and early intervention in autism spectrum disorders in lower- and middle-income countries.
abstract: There is limited information on autism spectrum disorders from lower- and middle-income countries (LMIC). This paper reviews the status of early identification and early intervention for autism spectrum disorders in response to the article by Camarata (2014) . The PubMed database was searched to identify relevant epidemiological studies from LMIC. Seven studies from five countries were identified: Colombia, India, Jamaica, Jordan, and Mexico. The mean age of parental concern, at 21-24 months, and mean age of diagnosis, at 45-57 months, were similar in LMIC, but later than in high-income countries. Both country groups reported language disorder to be the symptom of initial concern. Similarities in biological aspects of the disorders were noted across LMIC and high-income countries. Comparable ages of identification and diagnosis across vastly different LMIC suggest limited resources to be the underlying contributory factor. Recommendations for improving early identification and intervention made by researchers in the LMIC are reported.
