I kind of have mixed feelings about it. On one hand, a diagnoses could help get a handle on it young. I probably could have been diagnosed around 17. My symptoms started at 13-14. But on the other hand, children and adolescents change so much that it could be hard to differentiate what is normal and what is not. Also, not sure meds at a young age is that great unless the problems are very severe. My son is showing some signs he could have issues in this department. He's 11. Has had issues since he was 6. But how they displayed at 6 is not the same as now. Time will tell, I guess. I don't think I'd want him diagnosed with it this young, if he even is bipolar. He's already been diagnosed with ADHD.
