I have a Son who has Aspergers Syndrome and High functioning Autism and ADHD from what you describe it could be anyone of the Above You can have Aspergers syndrome and have Aspergers syndrome or one of the other ASD Disorders There is a very fine line between them some overlap it is difficult
my son was very fidgety he also could not focus for too long his short term memory was impaired he was singled out by normal children as different he would try and get attention but not intentially he worked better on his own and when he was in a classroom scenario his work deteriated dont know if any of this is helpful,
best wishes
Tom
