Other characteristics may include higher than average intelligence and vocabulary, and ultimately a tendency to see the world a different way, which can be scary to some neurotypicals.
It's a difference I have had to cope with all my life, having been diagnosed at the age of 7 and has caused me real difficulties in life (and to a certain degree, still does). I am not the only one it causes real difficulty to; indeed there is growing awareness of the problems faced by people with autistic-spectrum disorders, however some people seem to think the disorder is somehow "fake" or "not real" (I refer of course to some of the other definitions posted on here).
However, this does not bother me, rather it amuses me that a group of fat, comfortable individuals with time on their hands to spend posting ill-informed, pig-ignorant, and sometimes downright illiterate definitions on UD seem to think that their opinion somehow matters more than that of the world's smartest and most experienced people in the field of psychiatry.
The most commonly-known 'symptom' is having trouble in social situations, including problems making eye contact, for example. Sometimes, people with this condition may have poor motor coordination, which may lead to failure in team sports.
Despite popular opinion, people with Asperger syndrome do not have any trouble realizing social situations or people's emotions. They do, however, have a problem in responding accordingly, mainly because of the fear and tension that human contact causes. This fact is demonstrated by experiments that show that people with Asperger syndrome have no problem identifying the proper social behavior when in a controlled laboratory setting with no people around.
This is counter to people with autism, who do indeed have serious problems diagnosing social situations, not just problems responding to them.
Asperger syndrome causes a huge range of problems in life that can manifest or lead to depression, social anxiety disorder, rejection, and even suicide in some cases.
Despite this, Asperger's is no excuse not to try to lead a normal life, as demonstrated by the large number of people who have succeeded at their jobs, at social life, and marriage despite having Asperger's. However, a person with, say, diabetes may live a relatively normal life too. Just because a disease does not force one to live their life on a hospital bed doesn't mean it is not a real illness.
Aspies have a hard time making friends in a world, mainly becuase their high IQ's, literal imagination, and superior adherence to company and school rules and respect for authority.
Tragically since Aspies are essentially just a more moral and intelligent version of NT's their social abnormalities make them "geeky" and "nerdy" and their non-understanding of social cues make them seem like assholes.
Living in a neurotypical world with NT's the majority of who would rather remain ignorant and alienating then seek to understand AS does not help, nor does it help to claim that you have AS to excuse your idiotic and asshole behaviour.
Asperger Syndrome is not the problem in our world. Ignorance is!
"Craig Nichols, lead vocalist for The Vines, has Asperger Syndrome. He describes his situation with his family in the song "Spaceship"."
Person with HFA: I have high functioning autism.
Aspie: I'm more high functioning than you!
Person with HFA: No one cares.
Usually kids are labeled with Asperger Syndrome...think typical nerd or dork, paces around, thinks about something besides sex but masturbates and wishes he could get sex, maybe obsessing on something not cool, watches Spongebob (there is something about Asperger Syndrome and Spongebob, or any socially inept kid), using correct English and not street slang, but made even more dorky with a disability. There is a dime of dozen of these kids and that actually adds diversity to high school or middle school. We need kids that are socially inept and can't get the chicks. Propaganda for discrimination and makes the popular group more snotty and the teachers that suck up to the popular group.
