I've got ADHD and stimulant meds help me get distracted less, but they don't do much to help me focus on the right things sadly. Still definitely helpful though.
But no, I (a complete amateur with zero qualifications) highly doubt such a drug is possible, and if there were one it'd be kinda uncomfortable to ponder the very concept of making neurodivergent brains work like neurotypical brains at some point.
Like, why should we have to change when it's society that sucks, not us?
