Reply to comment by peer-reviewed-myopia in Depression can lead to memory dysfunction. This study may pave way for new drugs. Results of a large study involving brain scans show that patients with moderate to severe depression have 7-10 per cent fewer serotonin 4 receptors in the brain than healthy test subjects. by Wagamaga

But wasn't there a recent study that showed SSRIs are no more effective than placebo?

There was a study saying that there is no good evidence that low serotonin levels being related to depression.

SSRI's do work for some people but they aren't fixing any underlying chemical imbalance in the brain. Think of them as a painkiller, they help with the symptoms but aren't fixing some underlying issue.

I don't know the study you reference, but SSRIs and SNRIs were shown to improve depression over placebos countless times for a long time now. It's no miracle, mind you, but it still works at least better than nothing

I found it. It was this paper. For 85% of people SSRIs are no better than placebo.

That study defends my point though. It's right in the abstract

>Results The random effects mean difference between drug and placebo favored drug (1.75 points, 95% confidence interval 1.63 to 1.86). Differences between drug and placebo increased significantly (P<0.001) with greater baseline severity. After controlling for participant characteristics at baseline, no trends in treatment effect or placebo response over time were found. The best fitting model of response distributions was three normal distributions, with mean improvements from baseline to end of treatment of 16.0, 8.9, and 1.7 points. These distributions were designated Large, Non-specific, and Minimal responses, respectively. Participants who were treated with a drug were more likely to have a Large response (24.5% v 9.6%) and less likely to have a Minimal response (12.2.% v 21.5%).

Depression is an insanely difficult to treat disorder. There is no one drug that cures it or even makes it manageable for everyone; hell, they din't help me a whole lot with it. But the medicine works for some people. More importantly, it seems to help more those with a more severe depression. It's no miracle, but it can help some together with therapy.

We still don't have a good drug for it, sure, but it's not like a placebo, it does help.
