  • Prevalence ~1% in UK; male:female ratio ~3-4:1 - females frequently underdiagnosed due to camouflaging/masking
  • ~50% of people with ASD also have a learning disability; ADHD co-occurs in 50-70%

The MMR vaccine does NOT cause autism. This originated from a fraudulent, retracted 1998 paper. A common exam distractor.
