Even if depression isn’t caused by low serotonin, as Joanna Moncrieff sets out in the book you reviewed, I am glad to see some researchers have pointed out that this doesn’t mean SSRIs, drugs commonly used to treat it, are ineffective (18 January, p 28).
In my view, the most obvious explanation for depression in the modern world is that we are in an environment grossly mismatched to the one we evolved for.
