Below is an interesting article exploring the idea of anger management and whether or not it is a stand alone issue or is, rather, an indicator of some other underlying issue or diagnosis. The article covers both areas but the main idea here is that difficulty managing anger is not usually a stand alone issue but rather an indicator of other problems such as depression, bipolar disorder, anxiety. Anger can also be a defense against other feelings meaning that the person is more comfortable and finds it easier to express anger than, perhaps, sadness or fear. The bottom line is that while there is such a thing as Intermittent Explosive Disorder, don't assume that it is just a problem controlling anger. It could be an indicator of something else.
