It means your brain works in a different way from other people. It's something you're born with. Signs of autism might be noticed when you're very young, or not until you're older. If you're autistic, you're autistic your whole life.

Why is autism life expectancy lower?

Accidents. While we must ask questions about potential genetic and neurological disorders for our loved ones on the spectrum, accidents remain the number one reason for the lower autism life expectancy. According to the National Autism Association, 48% of children with autism have wandered off from their families.

Does maternal stress cause autism?

While prenatal stress and maternal immune dysregulation are associated with ASD, most cases of these prenatal exposures do not result in ASD, suggesting interaction with multiple other risks.
