A study has estimated that one in every 127 people globally, or 6.18 crore individuals, had autism in 2021, with the neurodevelopmental condition featuring among the top 10 causes of non-fatal health burden in youth aged under 20 years.

The disorder is associated with repetitive behaviour and affected social skills. Signs, which can begin to show as early as 12 months of age, include poor non-verbal communication, such as avoiding eye contact and not responding to their name.
