|From the DSM IV Introduction:|
"Moreover, although this manual provides a classification of mental disorders, it must be admitted that no definition adequately specifies precise boundaries for the concept of "mental disorder"...
"In DSM IV, there is no assumption that each category of mental disorder is a completely discrete entity with absolute boundaries dividing it from other mental disorders. - or from no mental disorder."
"New knowledge generated by research or clinical experience will undoubtedly lead to an increased understanding of the disorders included in DSM IV, to the identification of new disorders - and to the removal of some disorders in future classifications."
Ie 'all those drugs you were taking for "blahblah disorder"? Well it's no longer a disorder! - you can stop taking the drugs now, they weren't actually necessary or doing anything for anything after all! - but better yet, keep on taking them while we find some other disorder to fill its place - always subject to recall, mind you!'
