Christopher Boone and the Asperger´s Disorder

Christopher Boone is a 15 year old boy who suffers from a syndrom called the Asperger´s Disorder which is a"milder variant of Autistic Disorder". That means that he has problems recognizing facial expressions, likes to be alone ( social isolation) and can´t stand to be touched in any way. Furthermore affected people tend to concentrate all their attention to a certain field of interest, in Christophers case math, physics and astronomy, but lack knowledge in other more common things. Sometimes when there is too much information coming in at the same time it confuses him so he doesn´t know what to do and what to answer etc.
Later we find out that his biggest wish is to become an astronaut. Therefor he wants to take the A-Levels in math and physics and study at a good university. This really encourages him but is kind of hard to realizes because he goes to a school for handicapped children. His father tries everything to make it possible for him though.
