Is it possible to develop autism later in life (like as a teenager or into adulthood)?
Or another words can people be totally “normal” as toddlers and children, and show signs for it as they grow older? Thanks 🙂
Oh and no I do not think I have autism or any other mental disability. I am purely curious because I am reading a book about someone living with autism right now.
No. Autism is a developmental disorder, meaning the symptoms develop early on and last throughout the lifetime. One of the diagnostic criteria is that the symptoms must be apparent by the age of 3. If autism-like symptoms appear later, it is due to some other cause.
