alt Hacker NewsWhat's your opinion of the claim that antidepressants have small impact on people with mild to moderate depression, but significantly more impact on people with severe depression [1]?
I ask as a nonexpert because this is a view I've read a few times from people I trust more than most, and I know two people who suffered from severe depression who credited SSRIs for getting them through.
Honestly, every time I look into if the "treatment by severity effect" is clearly established, I feel I come away only able to shrug. It is at least plausible, but hasn't been clearly established or refuted.
What does seem clear to me is that the whole cost-benefit considerations change in favor of anti-depressants when the depression is severe. I wouldn't say anti-depressants should be first-line treatments for ordinary depression, but for severe depression, I think they are a very reasonable first-line option.
Sure, they still might not help, but the costs / harms don't seem so bad compared to the potential costs / harms of leaving the severe major depression untreated, and the other options look all pretty terrible here too.
