The Character of Alex P Keaton has been added to the "famous people with high functioning autism or autistic traits" web site.
This site include real people plus characters in books, movies, and tv shows both past and present.

I edited your post to make the link work (as it was now, the link only covered a small part of the address, and it was therefore not possible to click on it to get to the page.

For the record, I don't think the producers intended the character to be high-functioning autistic, though.
