I answered yes to around 20 of those questions. My son has a formal diagnosis of Asperger's. I am positive that I have it, but don't see any reason to get a form diagnosis because I don't see any benefits to a formal diagnosis.
My Mom, some years ago asked me to take a quiz for Asperger's. Some of the above factors are related to unsolved nearsightedness. If one doesn't see well enough, one may miss the information being communicated through / by the eyes. And since some consider it rude to stare, why keep the focus on the person you are talking to. So many more factors to consider. If one didn't talk he's 5, and then started school at six,----- hedh naturally have less confidence talking than his classmates who had been talking for 2 to 4 years. Some mainstream American (drug-salesmen-type) medical theories are opportunities to the truth on the subject -- especially when they have a drug they want to sell. Read the fine-print on those drug ads, and you will find that what conditions they (drug-salesmen) say their drug will help ----- is usually one of the same (or similar to) conditions listed as "side-effects" --- (the long-term--effects). Beware of all drugs!!!
