Apparently it's much more humane now...you sleep through the whole thing, and they use a small electric current to induce a minor seizure, which you will not be aware of due to anesthetic and muscle-relaxant. This is supposed to help increase the chemical activity in your brain or something, that part gets a bit hazy.
It does sound rather extreme, doesn't it? And it doesn't help that Hollywood loves to dramatize it.
It was recommended to me due to my clinical depression, which I've had for the last ten years. It's funny, it only occurs to me to seriously think about radical treatments like this after having a good day- not that today was a particularly great day in itself, but it was one of those rare days where due to a sudden extreme caffeine-adderall overdose/lack of sleep/god knows what else, I didn't feel that numbness I'm accustomed to. I walked around campus, dealt cheerfully with people behind office desks who were making my life difficult, made jokes to choir members and classmates without caring what people thought- it was kinda nice. And I know I won't have that tomorrow.
It's probably not the best idea. I dunno. The doctor who mentioned it says the only common side effect is a very short-term, temporary memory-loss (so if a friend drove you to the appt., they could mess with you a bit afterwards), which isn't a huge deal. But google searching tells me (and we all know the internet=infallible) about potential permanent memory damage, which scares the crap out of me. But I'm 22, I've been on and off different meds for almost half my life, and this is still a huge issue I'd like to move past at this point.
...to shock or not to shock, that is the question...
