Asperger. Main features are qualitative impairment in social interactions with lack of empathy, stereotyped restricted patterns of behaviors/activities/interests, no delay in cognitive development or language. Other associated features can include intense preoccupation with a narrow subject, clumsiness & restricted use of words. Applies to both sexes.
As for a male. Nobody really knows what this mixed gift is. It's supposed to be more common among boys. I've thought perhaps a girl with poor sports coordination, a bookish focus, and less ability to read others without thinking might be noticed less / worry the parents less and never have the diagnosis made. An aspie who learns diplomatic skills & has a socially useful focus is among the most likeable people.
