Codependency / Parent-Child pattern

I'm curious...


My wife is being treated for codependency.  I'm not sure how much of it is related to my ADHD and the drinking I was doing (now sober) vs. a childhood that I know had some serious issues that I won't go into detail about here.  However, I'm curious how the parent-child pattern of an ADHD relationship compares and contrasts from codependency.

Anyone with any knowledge they might share?
