BHHG,
I think we both agree that there is an issue about informed consent that is common to all treatments. At least you didn't contradict me when I made that point so I'll assume you accept it. That leaves us with....
You said....
1) I've not known of any cases where people were given ect as the sole treatment, so you are using ect as well as the other forms of treatment so are increasing your side effects.
This is because ECT is not a front line treatment. If properly used it is a 'last resort' treatment so of course we'll continue other anti-depressants because it's designed to kick start their effects. It is used in cases of profound depression to effectively 'kick start' the brain chemistry to allow people otherwise moribund or suffering from psychomotor retardation to begin to benefit from more traditional treatments. Why discontinue something that will take a month to return to therapeutic levels when the whole point is to boost the therapeutic effect of that antidepressant in the first place? To give ECT without concurrent antidepressants would be pointless and therefore cruel precisely because it is "the sole treatment".
2) Side effects of other treatments such as medication usually last for the duration of the treatment, or sometimes for a short while at the start of the treatment whereas with ect the side effects are often permanent.
Which side effect do you mean BHHG? Is that the short term memory loss. So there are a few hours of profound depression that I will never be able to remember. Guess what - most people don't remember every moment anyway and certainly not when profoundly depressed. But, given that memory loss does occur for the few hours around ect administration let's consider just what is lost. A few hours of misery are forgotten as the price to pay for a lift out of depression that allows a person to permanently regain their life - you see the positive effect can be permanent too but only if combined with other treatments such as either anti depressants or psychotherapy or both.
Incidentally your assertion that side effects of other medications are temporary is badly flawed. Actually with the exception of not remembering a few miserable hourts of profound depression you are much more likely to suffer permanent side effects from pharmacology than form ECT.
3) The benefits of ect are often temporary and usually provide benefits for a limited time only and you are then back to square one
This isn't specifically the case for ECT. Some people recover permanently from depression and some relapse. Why single out ECT for this criticism. The actual problem here is that no treatment guarantees a permanent cure for depression. To attempt to make a single treatment responsible for a wider problem is disingenious and smacks of the sort of prejudice fuelled by newspaper reports and works of fiction such as 'one flew over the cuckoos nest'.
Anyway - ETC isn't designed as a long term treatment (actually it was never really designed at all but that's another story). ECT is used as a short term kick start to allow other treatments to work.
I'm not an advocate of the biomnedical model by any means but there is a genuine problem here. Profoundly depressed people kill themselves. That's bad. For some people there is no realistic treatment other than ECT because there depression is so profound.
ECT may not have a nice reputation but that doesn't mean it is barbaric whatever the Daily Mail says. And it does save lives.
Can I suggest that you see if you can get a placement during your training that will allow you to observe administration of ECT. I think you'll be surprised at the rather less than barbaric process involved. You might also find the change in the patients' mental states quite inspiring too.
Cheers,
Stuart
