The writers did not write the characters with the intention of Sheldon having Asperger's Syndrome (AS), but as one of the personality types one meets in college science majors. However, many people with AS, as well as some psychologists, believe that Sheldon has AS.

The other three men also are written to have personality types observed in science. Many people think of them as being science nerds (or similar terms), but not as individuals with Asperger's Syndrome.

Jim Parsons, the actor who portrays Sheldon Cooper on The Big Bang Theory, is unlikely to have Asperger's Syndrome. He does not seem to have typical behaviors of a person with Asperger's Syndrome when he is interviewed.
