Neuroskeptic - Antidepressants Still Don't Work In Mild Depression

Imagine that - Big Pharma has decieved us. This research review comes from Neuroskeptic - a very excellent blog.

Antidepressants Still Don't Work In Mild Depression

A new paper has added to the growing ranks of studies finding that antidepressant drugs don't work in people with milder forms of depression: Efficacy of antidepressants and benzodiazepines in minor depression.


It's in the British Journal of Psychiatry and it's a meta-analysis of 6 randomized controlled trials on three different drugs. Antidepressants were no better than placebo in patients with "minor depressive disorder", which is like the better-known Major Depressive Disorder but... well, not as major, because you only need to have 2 symptoms instead of 5 from this list.

They also wanted to find out whether benzodiazepines (like Valium) worked in these people, but there just weren't any good studies out there.

The results look solid, and they fit with the fact that antidepressants don't work in people diagnosed with "major" depression, but who fall at the "milder" end of that range, something which several recent studies have shown. Neuroskeptic readers will, if they've been paying attention, find this entirely unsurprising.

But in fact, it's not just not news, it's positively ancient. 50 years ago, at the dawn of the antidepressant era, it was commonly said that most antidepressants don't work in everyone with "depression", they work best in people with endogenous depression, and less well, or not at all, in those with "neurotic" or "reactive" depressions (see, e.g. 1, 2, 3, but the literature goes back even further).
