Dysregulation Disorder is, supposedly, just a new designation and reclassification by the American Psychiatric Association of bipolar disorder. A difference between the two disorders being the time frame. Dysregulation disorder, unlike bipolar, disorder is not a lifelong disease - you grow out of it.
It seems as simple as taking the one disorder, and classifying it based on the age of the individual affected. If you're still in some sort of growing mode, you suffer from dysregulation, if you're a full-grown adult you suffer from bipolar. I suppose then, if you were still symptomatic and grown to an adult you would be then be re-diagnosed.
Some mind-docs are concerned of the over-diagnosis of bipolar (a sentiment, btw, that is shared by some around here). And particularly in the diagnosis of young people.
Complicating and confounding things, as always, is the health insurance issue. Most insurers won't cover any sort of treatment for a disorder whose cause may be environmental in nature. Bipolar disorder is recognized as being a medical condition.
Anyways, I'm curious what Anna, Smash and others think about dysregulation disorder. Is it a viable diagnosis? Will it catch on? Will it be covered by insurers?
