Also the social defits in schizoid personality disorder are not apparent until later school years instead of preschool years of AS.
One difference between the schizoid group and AS is the presence of imagination and fantasy within the schizoid group and the concreteness and creativity defits in the AS group. Other difference is the lack of intense special interests as mentioned above.
Most people at Wrongplanet.net claim to have imagination and fantasy (there are recurrent threads about that).
And if you take a look at schizoids.net, most of them claim to have been loners since the first day of school.
I wonder if the difference between "age of onset" are not largely the result of social change: the diagnosis of AS become famous at an age (1990s) when the majority of children go to pre-school, kindergarten, etc., while "schizoid" was a concept created in the first decades of last century, where children spend their pre-school years with family and/or playing with 2 or 3 other kids of the neighbourhood; in these times, it was natural that social deficits began later - true social life began later, also.

Yeah some authors claim that schizoid personality disorders should be part of the autistic spectrum as mentioned above.
A possible "problem" is that, if we include SPD in the Autism Spectrum, we could end up with what will be, basically, a "Schizoid Spectrum":
The range of estimates of prevalence for SPD go from 0.5% to 7% of the population, but most estimates are between 1% and 3%; attending that current estimates for ASD are around 1% or slightly below, the "typical" person in these enlarged spectrum will be the current "typical" schizoid.
