Autism spectrum disorder (ASD) prevalence has significantly increased, with 1 in 68 children diagnosed as of 2012 and a marked rise of 120% since 2000. Early diagnosis is possible as young as 18 months, and early intervention with applied behavior analysis (ABA) therapy, endorsed by multiple organizations, can lead to improved outcomes in communication and daily skills. The effectiveness of ABA therapy varies based on intensity, with studies showing better results for those receiving more hours of therapy.
