For clarity, Asperger Syndrome may occur at any I.Q. level from about 70 upward, but this inventory is aimed at the combination of Asperger with high intelligence in adults, with its specific problems. There is no claim of an adult onset of the condition, which starts in infancy and is lifelong. In psychiatry, adults with Asperger have often received alternative diagnoses such as schizophrenia, depression or almost any personality disorder. Asperger Syndrome, by many thought identical to high-functioning autism - and in fact one is planning to abolish the Asperger diagnosis altogether in favour of "autism spectrum disorder" -, is especially similar to Nonverbal Learning Disability and Schizoid Personality.
Obviously, not all highly intelligent adults have Asperger. With no or few features from the list one does not have the condition. Even with a high score, one should realize a diagnosis can not be made on this basis, but requires interviews and observation in person next to psychological testing. Although GAIA was originally conceived to detect Aspergoid features, it may actually be measuring a more general disposition for psychiatric disorders without in itself being able to point to one specific disorder.
