Over 80 percent of children with autism spectrum disorders live in low-and middle-income countries, posing challenges for the local health systems. Not addressing autism at a young age has a profound influence on development into adulthood and results in a high economic cost, exceeding the lifetime costs of asthma, intellectual disability and diabetes. India has about five million children with autism but, outside major cities, there are no services for diagnosis or community-based care available, due to low awareness and a shortage of mental health specialists.
