My 16 yr old difficult child has carried the diagnosis of bipolar not otherwise specified since he was 8 yrs old. He has been treated with every medication and combination of medictions for Borderline (BPD) with no change or improvement. He has been hospitalized over 15 times = more than 2 years of his life. He has been in counseling and every therapy known to mankind and nada. I have altered my parenting over the last 16 years to make sure that I have left no stone overturned....again nada. Fast forward.....Due to changes in ins., I had to change psychiatrists and tdocs. New guy does extensive interviews and studies all medical records. He calls us in tells us that after examining all the records and notes from hospitals and juvie and tells me that my son is not bipolar and in fact has DMDD. What is this you say? DMDD stands for disruptive mood dysregulation disorder charecterized by constant irratability which gives way to horrific explosions to even minor events. It will not be helped by bipolar medications or adhd medications and these in fact will/can make it worse. It is not in the "book" of recognized childhood mental disorders. It is being considered. It makes more sense than anything else I have been told. It is a brain disorder and not a chemical imbalance. There is a push to get it into the "book" so that treatments can be researched and ins. companies cover it. We have been in limbo for years, but at least it has a name. If your children fits this bill or think they might, I invite you to google it and see if that is a more accurate description of your child than Borderline (BPD).
