We looked at research on serotonin levels in body fluids, levels of the main metabolite (breakdown product) of serotonin in the cerebro-spinal fluid (brain fluid), serotonin receptors, the serotonin transporter protein (the protein that removes serotonin from the synapse where it is active-…

Continuing the antidepressant debate: the clinical (ir)relevance of drug-placebo differences

The results indicate that the small differences usually found between antidepressants and placebo are far below the sort of differences that would be clinically detectable or meaningful.
