I have high-functioning autism and my 12 year-old cousin doesn't know what autism is. I cannot fully explain it because I don't fully understand it myself. And I don't want to search the internet because results vary. So how can it be explained?
My little brother has autism too and i looked it up on this website so i could understand it it might be helpful for you not sure but here you go. autismawarenesscentre.com
