I am sorry, I cannot tell you.
I am 41 years old and I still have problems processing verbal/ communicational interaction, by that I mean hearing but not profoundly processing and realizing what someone has said, but I lack, I guess, mental flexibility to put it into context for myself.
But I have not been diagnosed at young age as well, meaning I had no intervention, but maybe other people here can give you advice.
