ADHD, aging and menopause

My wife has ADHD, PMDD and other disorders.  I don't need to reiterate the common problematic issues of relationships here since that's all over the forum.  However, she's heading towards perimenopause and I am... uh... scared.  She has her mood swings under control with medication at the moment and some emotional management tools, therapy.  We have rules to protect me also because she used to be emotionally abusive with me though, and still has impulsivity issues etc.  The other ADHD issues are things she is working on.

I can't find research on ADHD and it's relationship to aging and menopause.  Anybody have resources?  Or personal experience to share?  Tips?

Thanks! :)
