I would highly doubt that Tolkien or Bilbo or Frodo had any kind of syndrome, or disorder. They just all represent a type of person who is prevelent in all types of society. I think though that the way that they acted was because of their personality (talking about Frodo and Bilbo), and of course the influence of the ring, that does tend to make you a little more private and sheltered (example: Gollum). And another thing though is that we really don't know if Frodo and Bilbo were the only hobbits who were more private and less social. There could have been other ones, but we just never heard of them because they were so sheltered. I think there would have not been as much attention placed on Frodo and Bilbo if they hadn't of had all these things happen to them. They most likely would have just lived their life with very little attention paid to them.
