Here’s a concise breakdown based on trusted sources:

**Causes**: While the exact causes of autism spectrum disorder (ASD) aren’t fully understood, research points to a combination of genetic and environmental factors—*not vaccines* (Autism Society of NC, CDC).

**Prevalence**: The CDC estimates 1 in 54 children in the U.S. has ASD, with boys being over 3 times more likely than girls to be diagnosed. Rates vary globally (WHO, CDC).

**Treatment**: Options are personalized but may include behavioral therapies (like ABA), speech/occupational therapy, and sometimes medications for co-occurring conditions (e.g., anxiety or ADHD). Early intervention is key (Mayo Clinic, NIMH).
