Just curious - I have no particular insight.

Also the following, along the lines of what I remember reading recently; testosterone blockers appear to help some very early symptoms of autism, too:
Two preliminary studies have linked lower neuron density in the amygdala with autism. It is unclear whether this could be a cause or an effect of the condition. It is postulated that this physical difference may directly lead to symptoms of increased anxiety and nervousness, and indirectly (through some unknown mechanism) to poor social skills.
BTW, haven't exchanged with you in a long time. Hope all is well with you and yours.
