Asperger's syndrome is a neuro-developmental disorder, one of the suite of conditions making up the autism spectrum.
While people with Asperger's have an intellectual capacity within the normal range, they experience problems with social interaction, and difficulties understanding the nuances of emotion, as well as intense preoccupation with a particular subject or interest.
These difficulties are often offset by exceptional abilities, brought about by the intense focus that forms part of the disorder.
