It's not exactly "executive function in a pill", but in people with ADHD, stimulants help with task initiation and sustained attention. That's often enough to help people create a structure for creating and maintaining habits that work for them.
> Here’s an example: you (having undiagnosed ADHD) try to set a schedule, or use a todo list, or clean your bed every day, but it doesn’t stick. So you [get diagnosed and then] get on medication, and the medication lets you form your first habit: which is using a todo list app consistently, checking it every morning.
> Even assuming a health care system that actually cares about ADHD in adults, "just get a diagnosis" seems like a much higher bar than "just clean your bed every day".
I would elaborate if I understood how there's any room for confusion. I don't.
I was fortunate to find a physician that specializes in ADHD. Most of his patients are children/teens but they also see adults like myself. You can also go the route of seeing a psychologist that specializes in ADHD.
