DMDD is Disruptive Mood Dysregulation Disorder, a new diagnosis added to the latest DSM manual as of 2013. It got added to my grandson's alphabet soup diagnoses of ADHD and Anxiety Disorder. It is a controversial diagnosis that is trying to find a diagnostic home for kids that might previously diagnosed with child bi-polar, but that don't seem to grow up into bi-polar people. For my grandson, it was attempting to explain that near constant irritability and feeling like he was going to blow up any minute over any little thing. When this one got added, it changed the medications, too. Although he doesn't have the cruelty thing that your daughter seems to be displaying. Does she hurt animals? Has she physically hurt her younger sister?
