I've read so many comments on the Forum recently about ADHD partners/spouses who seem to have problems with anger, and in some cases..rage.  I can certainly appreciate how difficult it is to live with someone who seems to get triggered into this kind of reaction without a substantial reason.  Melissa recently wrote an article on just this topic in EMax Health.  Research done in Feb. seems to suggest that those with ADHD may be genetically predisposed to what is called "emotional lability."  This is just a fancy term for moodiness, ie. irritability, or a short fuse...anger responses.
