Does Batman have ptsd?

I think there are good arguments for the view that he does. According to a stat I saw online 90% of children who witness a parent's murder will get ptsd. Bruce Wayne also has intrusive flashbacks about his parents' murder. He frequently relives it by beating up and catching criminals. He also appears to have no interest in the things many other people enjoy like socializing, hobbies, etc.

When I saw The Dark Knight, I thought he had a pretty clear case of PTSD.
