I assume you refer to political "liberalism" as opposed to a purely personal liberality.
I don't think that subscription to political liberalism is caused by any specific neurological cellular or chemical malady.
I tend to believe that it might be caused or made more likely by an individual's lack of self-restraint or discipline, a tendency to emote rather than coldly analyse, and a retention of infantile tendencies to desire and defer to/depend on some kind of Parental Figure.
that might be a training-induced neurosis, but falls short of a true pathology or psychosis.
