Just a Bad Temper?

I read with great interest this article in yesterday's National Post. It revolves around the proposed inclusion of a new children's behavioural disorder called, TDD, temper dysregulation disorder with dysphoria, in the Diagnostic and Statistical Manual of Mental Disorders. A diagnosis of TDD would be given to children, ages 6 and older, who have wild mood swings and physical and verbal outbursts and rage, much akin to the temper tantrums of a 2-3 year old. One of the goals of including TDD is essentially to provide a "less-severe diagnostic home" for children who don't quite meet the criteria for bipolar disorder, a disorder that, according to the article, is severely over-diagnosed in children who are then being medicated and labeled. Clearly there are a number of very real issues here. I'm curious to hear your thoughts. I'm sure you all have opinions about this subject.
