Jym, we were given that 95% statistic for ADHD in the bipolar population by one of the head psychiatrists at MGH’s pediatric center for bipolar disorder, maybe in 2010. You may have more current information. In my own view, I would think that bipolar disorder itself might bring some of the challenges diagnosed as ADHD. However, with excellent results for treatment of bp 1 in one of my kids, I see no resolution of her problems with focus : ) Despite incredible effort.
I think every brain is unique and don’t find differentiating in terms of labels that helpful anyway, but my agenda is simple, unlike insurance companies who need codes!
