Hmmm...I wonder what he was talking about, then. Have you had a chance to watch that video about the metabolic effects of atypical antidepressants? I may not of completely grasped what he was saying about sibutramine. I would be interested to hear your feedback on the lecture.

The way the commercial goes: "...people who abuse Meridia may become dependent," I thought this stuff was like an amphetamine or something. Why do you think they're treating it like this?

I think some people can actually *lose* weight on Moban!

> > I think the blockade of 5HT-2c receptors in the striatum is one of the things that makes the atypicals different. Blockade at these sites increases dopaminergic activity in the striatum, hence the fewer incidences of tardive dyskinesia...or so it has been hypothesized.

Negative symptoms...like flat affect, etc?

heh heh heh...

It will be interesting to see what the outcome of the drug's use is in the long term. I remember when there was discussion in the late eighties (and early nineties) about using SSRIs as diet drugs...whoops!

No, of course not...but can it be figured out? If the brain were simple enough to be figured out, would the mind of such a brain be intellegent enough to do the figuring? Did that make any sense? wait...huh...? ;-P

yeah, I was just being a smart allec (sp?) :-)
but kinda serious at the same time...I think treatment plans need to be highly individualized

That's kinda funny...but if it works and helps people get well...why not use that definition?

It's a partical, it's a wave, it's...
