Angry kid is either Disruptive Mood Dysregulation Disorder (DMDD) or Oppositional Defiant Disorder (ODD)

How can you tell the difference? No body seems to fucking know because DMDD is a new disorder in DSM-V and the criteria are very similar.

The best adivce I recieved for test taking is look for the word vindictive (It indicates ODD) or if the kid is angry with his peers (indicates DMDD). And if you are still in doubt remeber that shelf exam questions are generally old questions so pick the disease that existed earlier, ODD.
