I mean, the human brain changes constantly anyway, although supposedly less past age ~25. For this reason, for me staying myself is a moot point. It's an illusion our mind creates. And I've heard powerful arguments that one has to trick the mind to feel happy anyway (although they don't phrase it like that). I had to trick it and mold it to get out of depression, and others use drugs. Aspergers is somewhat different, but if it's accompanied by social anxiety, you also go and trick your brain to accept a certain amount of social discomfort. If there's a treatment to influence the process, why not, I say. It's another thing that it's a nuanced condition and I wouldn't advise using a hammer like ECT, if that's what it's about.
