Depression 'is NOT caused by low serotonin levels', study
Low serotonin levels do not cause depression, according to a major review. Researchers from University College London said a review of evidence has found no link between low serotonin levels and depression casting doubt on antidepressants designed to boost levels of the 'feel good' chemical. However, it does suggest the drugs don't treat depression by fixing abnormally low serotonin levels. They found there was no difference in serotonin levels between people diagnosed with depression and healthy people, despite polls suggesting up to 95 per cent of the public believing this is the case. Source: NHS Choices Co-author Dr Mark Horowitz said: 'I had been taught that depression was caused by low serotonin in my psychiatry training and had even taught this to students in my own lectures.
