One who has Asperger's (often shortned to AS) is likely to have social difficulties, and may experience speech delays or problems with motoric skills.
It is important to understand that there is a spectrum, where one can have mild AS or severe AS, and most symptoms can be mild or severe as well.
People with AS have a tendency to be loners due to social difficulties. They may have trouble making eye contact, starting conversations, or they will obsess over a certain subject.
A list of all symptoms would be long and is more fitting to an encyclopedia or psycological handbook than a dictionary.
People with Asperger's Syndrome are not neccesarily less intelligent as stereotypes would have one believe.
However, the common man (because of his natural fear of what he dose not understand) often considers a man with said advantage to be a retard because of his lack of social skills. But intellectually speaking, humans with asperger's syndrome are more intelligent than the common man. Hyperlexia is also common amongst these neurological variations of humans.
Aspergers Syndrome can be mild or extreme. Its a gift and a curse at the same time.
Its known mostly for being a social issue. People with it can walk and talk like normal people but the ability to handle talking with people, dealing with people, understand social "cues" and even so much as going up and asking for a new cheeseburger in a restaurant if it is made wrong without feeling like a complete idiot and fearing what the people working there are thinking of them can and will be VERY hard. In other cases, so much as walking down the street is a problem for these people.
People with aspergers syndrome often have very small interests for example computers or radio or a certain TV show or music. Because of their lack of the ability to deal with people, people with this issue often stick to themselfs. Often in their rooms. They learn about their favorite subjects to the point of having encyclopedic knowldege of the subject. This is partially where the term "little professer" came from.
Aspergers Syndrome comes with a few additional problems. People with it often have strong OCD and deal with panic attacks.
Poeple with it have problems being touched. So much as being hugged or touched by their parents, family or anybody even close to them can be a very bad expirence for them.
grooming, wearing of socks, can be a problem.
bad posture is also a common problem with people with aspergers syndrome.
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!
