Ds12 in the 6th grade is an asperger's kid and was diagnosed at 9 years old in the 3rd grade.
We always knew he was "different" but didn't have a clue what was going on - never even heard about Asperger's until he was diagnosed. (I highly suspect my dh and his father are also Aspies...)
Ds has a very high IQ but does not do well in school. He finds most of the things they do in school to be "stupid" and a waste of time. He fixates on one subject at a time. He will ONLY listen to the music of The Beatles so that's what we hear over and over and over...at least they have a lot of albums!

He is also big into Pokemon - such as drawing the characters and playing the games on the gameboy and gamecube.
Ds is not into sports...is not coordinated..never learned to ride a bike or tie his shoes.
Ds does make eye contact and is very social - altho he talks AT people and not WITH them. A couple weeks back he had a friend (girl) over and he started talking AT her about the "Paul is dead" conspiracy and I had to gently tell him that not everyone is as interested in that as much as he is.
There are so many things that ds does that other "normal" kids do, but he does them to the extreme. When younger he had more tactile issues - socks couldn't have seams, shirts couldn't have tags, noises and too much stimulation did him in. Routine was very important - he did/does not like surprises.
Ds has a lot of problems with social situations - he just doesn't know what to say or do and he ends up standing around a lot on the outside of groups. He does have his friends tho (they are like him) so that helps.
Ds can recite various Pokemon facts but still doesn't know his times tables.
When ds hit 6th grade this year he went into a tailspin due to all the changes for classes, the need for organization and more responsibility. When it all gets to be too much he puts his head down on his desk (or bangs it) and then shuts down completely. Back in 5th grade he was stabbing himself with his pencil when frustrated. Several months back he destroyed the frame of his bedroom door with all his slamming when frustrated. The door is also destroyed (big crack down it) and there is a small hole in his bedroom wall due to kicking it when he was mad. We have not repaired any of these things as we want them to serve as reminders to his behavior.
Ds does all the physical things to himself.
We recently had him tested by a neuopsychologist. We had testing done when he was in 3rd grade but at his current age they can do more/different tests. It was discovered that ds has several learning disabilities, including auditory processing problems. It certainly explains many of the problems he has in school. Right now we are in the process (along with his school) in finding another school situation for him. In school now he is pulled out for a couple of classes and he even has a one-on-one aide and he still has breakdowns. These kids sometimes just can't be in a regular school situation.
I have heard of many kids first being diagnosed as ADHD when younger and then diagnosed with Asperger's when older. Dh has a nephew who fits that but his mother is in denial. We have been down the medication path and at times it has been good and at times it has been a nightmare. Seems that the dr's are very quick to prescribe. Last time we went in we wanted to cut out a medication (wasn't doing any good) and ds' dr. wanted to add another one to make it three! We said NO and we are now weaning (under dr's care) ds off one drug. This summer we may try to wean him off his other drug and see what he is like drug-free. We are hoping that once we can eliminate the school stress then other things will be better. It is such an unknown and we can only hope.
AsPerger's is a very complex diagnose and not all kids will have all the symptoms. Many of the kids can go through school and not have much difficulty, unfortunately, my ds is not one of them. Many of these kids are extremely bright and do ok in life - many go on to become engineers! (dh is one

)
It can also be a very, very tough thing to live with at times.
