First of all, ADHD is often co-ocurring with other things, like autism.

Second, medicine is helpful, but it's not a panacea. Also, two common ADHD medicines in the US face FDA-imposed shortages, so prepare for many calls to the pharmacy.

Also, ADHD is not just hyperactivity and attention--it impacts emotional regulation, impulse control, task initiation, time management, and other things related to executive functioning.

Finally, ADHD isn't bad. I like to think of it as an insanely strong, overenthusiastic hippopotamus--if you work with it and get to know it better, you will be able to have a hippopotamus friend, which sounds handy, but there's always the risk of it getting a little too excited and breaking stuff.
