I completely agree with your premise and the article. I think parents should try therapy and also look carefully at their childs diet. Many children who have ADHD/ADD and behavior problems improve greatly when the processed junk, which has additives and artificial colors is removed. Usually most doctors can't really determine if a child is bipolar until they're 18, because their brains and personality aren't fully developed.

Yes I know there are exceptions to the rule -I saw this one special where the young girl was seeing/hearing people and talking about killing members of her family.

There's also this not very well known medical condition called PANDA which stands for Pediatric Autoimmune Neuropsychiatric Disorder Associated with Streptococcus. In short the typical strep throat can lead to sudden psychiatric symptoms.

Parents/doctors should try to look at a childs diet, use positive parenting, counseling first before jumping to medicating. Children do misbehave and that's part of being a child ( there are exceptions). Children aren't born knowing how to control their emotions and its out job to help them handle their out of control emotions in a positive way.
