I'm not sure whether things are over or under diagnoised. Does having a label help matters? I know that I've got many traits which are typical of many diseases (my thinking pattern is very common in people with schizophreina, I have depressive phases, I'm mildly dyslexic) and I'm sure if I was analysed fully I'd have all sorts of nasty disorders. But thankfully they don't affect my life much, and I consider myself to be fairly sane. So does diagnosing mild ADD, mild OCD or mild Aspbergers help? There's no definate treatment (although congitive therapy can help, but cognitive therapy can help a lot of people) so why the need to label it?
What Dunx describes above is almost exactly what happened to me but in reverse I think. The OCD arose because I was depressed and would obsess on tiny things, believing absolutely that those things were the cause of my depression and if only I could sort them out I'd be happy. When, of course, I didn't sort them out I became more depressed, and so on and so on. I can quite strongly reccomend hypnotherapy for the treatment of OCD. I wouldn't call it a cure but it sure helped me. As far as diagnosis goes I don't think with these things that it's that clear cut. It's simply what you might call a personality trait, and we all exhibit different personality traits in differring amounts. Some people are talkative, some are fly-by-night, some are obsessive. I think we assign the term 'disorder' when one of these traits goes to an extreme such that it interferes with the normal day-to-day running of our lives. If we had a sound scientific way of actually measuring the extent to which each trait applied to us, the the term 'disorder' would be redundant.
[Lib] I think the label does help. One of the things that helped me (and is still helping me) pull up out of the spiral of OCD was the fact that I could give it a name. I know now that I have an obsession, and that makes it less real so that I can actually control and sometimes ignore it. When you're in the depths of OCD you fully do not realise that you are obsessing, you just think that there is nothing else to life.
[st d] I can listen to anyone, but I hate talking. [Lib] Naming a thing (and to some extent inventing the thing by the process of naming it) can cut both ways. The Asp/Aut/AD(H)D concept is now out there to a degree to which it wasn't, not many years ago. This lets people use it as a convenient club to beat people they can't deal with, but also lets others recognise themselves in it and make contact with each other. I've read alt.support.autism on and off, and there's a lot of very interesting, politically conscious stuff goes by. In fact, a lot of the politics is exactly the same as for being gay, black, deaf, or female. For pretty much any position that has ever been taken on any of these issues, change the specifics and it would be something that someone has said about any of the others. [BM] Anyone who enjoyed "Curious Incident" might also be interested in Elizabeth Moon's Speed of Dark, an SF novel in which the central character is autistic. The characterisation is quite similar.
Having a label helped me a lot for similar reasons to FG - I could capture my demon. Looking back at my life and the way that things have gone, I can also recognise ADD behaviours there (indeed, recognising ADD behaviours in my school reports was a key element of the diagnosis). This gives me power to forgive myself: ADD is not an excuse for my poor performances in the past, but I've spent too much of my life thinking of myself as lazy and weak. I feel that I understand better why my education was so skewed towards things I liked, or why I flit from subject to subject, or why I will focus on interesting things to the exclusion of all else, or why I have such an appalling sense of the passage of time. Recognising these things (rather than blaming myself for them) has helped a lot.
I'm normal on the surface. Whatever demons I carry with me are my business, but I'm approaching 40, single, childless and seem to be attracted by, and attractive to, men 15 years my junior. Make your own conclusions, then keep them to yourself! ;o)
[Lib] Ah, but they're not just labels. They're objective realities. Saying that someone has ADD, for example, isn't just saying that they have a bunch of particular personality traits - it means that they have a particular genetically transmitted condition which causes those traits. As Fat German says, if you don't have the traits very badly, you probably don't have the condition with which those traits are sometimes associated. But if you know that someone does have that condition then you can treat it, if treatment is appropriate. Describing this kind of diagnosis as "applying labels" is as silly as talking of disgnosing a broken leg or lung cancer or any other illness or condition as "applying labels". Certainly I have found it enormously helpful to be properly diagnosed because it means I can recognise OCD things for what they are and deal with them accordingly. And this is true of many other people I have spoken to, with OCD and with ADD as well.
[BM] There is a crucial difference, though, between a broken leg and these mental conditions or constitutions. In the case of a broken leg, you can demonstrate the objective existence of a physical pathology, and there are treatments known to be effective in pretty much every individual case. For ADD and the like, no-one has demonstrated either an objective pathology, or an objectively effective treatment based on an understanding of the pathology. All we have is descriptions of symptoms that cluster together (although no individual need show all of them), vague genetic correlations, and supposed treatments of very variable effect. There may indeed be a definite thing wrong with the brains of OCD sufferers, and there may be possible treatments as effective as setting a broken bone and applying a cast, but currently, very little is actually known.
