I had parents who seemed quite cold and made very little emotional connection with me. While I don't think that that could in any way be said to have been the cause of my having asd, I suppose nevertheless there could be some degree of correlation between parents having a rather cold relation with their offspring, and their offspring having asd? On the basis that there exists some degree of genetic correlation between parents who have asd and offspring who have asd.
I strongly suspect in my case that my father, and possibly my mother too, had asd, and that could have been a contributory factor to their rather stand-offish relationship with me. So in that sense, it seems not unreasonable to make some level of correlation between cold parents and offspring with asd? Not a hard-and-fast relation between the two, and not a causative relation, but some level of correlation nonetheless.
