Gene therapies for other genetic conditions often do, but then those aren’t neurodevelopmental.
I’m kinda fascinated by the question of how something like this would affect me. Like the way a psychedelic experience can teach us lessons we still retain (and want to hold onto), like the way formative experiences leave deep traces in us even when when we grow and change, what features of autism would always ‘stay with me’ on some level? If things changed perceptually for me, what old habits of mind would I retain? What would I miss most? What would I not miss?
In a lot of ways I think temporary windows into different neurotypes would be much more interesting than purported ‘cures’. People don’t usually want to undo their own personalities, including mental dimensions like neurotypes. But who wouldn’t want to play with that a bit, if they knew it were safe?
