Um, and who was the first person with MPD/DID? Did a therapist come up with the idea and encourage it? Bet is was discovered, became popular, and THEN treatment got misapplied.
Sorry, SwimmingRiddles, I know people (two, anyway) who had MPD/DID way before anyone published any books on the subject, and it is a real condition, not just caused by hypnosis and suggestion (otherwise, how did they have personality switching DECADES before they started therapy, or ever heard of MPD?). Trauma can do some strange things, and it isn’t all the therapist’s fault. (Yes, some people were messed up by stupid therapists, but far from all of them.) That brain of yours can come up with some really creative ways to handle trauma, and DID is one of them. Fortunately therapeutic standards have been applied to treatment, so you don’t get a lot of the false memory thing anymore.
Personally, I think trends of these things are half suddenly finding out that that stupid/annoying/crazy/frustrating/frightening thing that happens to you might be TREATABLE… and half what is hot to DIAGNOSE (okay, people talk about it more if it is hot to HAVE). The disorders exist on their own, the trick is whether the doctor you see has ever heard of it, has a clue how to diagnose it, or can differentiate it from anything else in the same general category. If a doctor just came back from a great seminar on Social Anxiety Disorder, they may well be predisposed to classify someone with a panic disorder or agoraphobia as SAD, especially if it has been a while since they looked up the symptoms of panic disorders. Maybe they get lucky and the treatment for them all overlaps, and the person improves… then the next person with a panic disorder comes in, and the previous success leads to another SAD diagnosis. The label just became popular, not the disease. Society decides what is labeled just ‘eccentric’ or ‘just get over it’, too.
How about this kid? Never does the homework, doesn’t pay attention in class, solitary, brings inappropriate materials to school, appears to be depressed, scores lower than average on classroom tests and higher than average on standardized tests, can’t focus on any kind of math problems, turns in substandard work, acts bizarre at times… problem child? Maybe ADD? illiterate? depression? learning disorder? or maybe 3 standard deviations above the mean IQ, bored to tears and can’t see the point of trying anymore? Could be bad parenting, though. Or abuse at home. But ADD is hot, and the parents won’t sue you (or ignore you) for telling them to take parenting classes, and child abuse is too hard to prove - professionally risky. What’s the real problem? Profoundly gifted IQ, history of abuse, parenting/discipline problems, and dyslexia. Quick, better give him some Ritalin, or try some behavioral modification techniques. Heck, if it helps, that proves that it was ADD. And shaving a woman’s head was a cure for hysteria, too (hysteria included strange behaviors such as insisting on being allowed to go to college).
I think a lot of normal variations are getting treated as pathological because it is SAFER, simpler, and quicker to do that than find or fix the real problem(s). And a lot of things that are real problems but could previously be hidden (in misery) are now being treated effectively.
Oh, and DID is still out there, it just isn’t hot in the news, partly because therapists got sued for diagnosing it (malpractice!) so they tend to keep really quiet about it. And since it isn’t hot, people diagnosed with it go quietly about their business, taking leave from work without specifying the details to their co-workers, and spend their evenings in therapy. Nobody wants to hear about it, if it isn’t cool anymore, even if someone still has it. it fades to the background. Hey, women still get faint, especially during pregnancy, but we’re taught to sit down and put our heads between our knees until the feeling passes, rather than standing there waiting for the darkness to close in, hoping someone will leap to our aid. Nobody wants to catch us, and it is more embarassing than ‘ladylike’.
Next decade we’ll have another hot set of diagnoses, and the ones that are hot today will become ordinary and boring (or vaguely embarassing), or too touchy to approach.
