    Would you give the same advice to someone who was blind or in a wheelchair

No, I wouldn't. But as fellow ADHD sufferer (who has struggled greatly at times) I would vouch for the parent poster's advice.

ADHD ultimately comes down to coping strategies. At the end of the day you are going to have to develop strategies to focus and accomplish your work.

In this sense it is different than e.g. blindness. A blind person (I'm partially blind, too! fun!) can't cope their way to sight. But an ADHD sufferer is going to have to figure out a way to focus and accomplish work.

I guess if I was already hired I might consider bringing up the disability thing if my employer was doing some weirdo, directly-hostile thing w.r.t. ADHD like banning headphones in an open office. That would be a plan of last resort.
