A study by Dr Zhang Xiaodong of the Duke-NUS Graduate Medical School is set to better understand the interactions between stress and the serotonin system in depression. This could eventually lead to a better way of diagnosing and managing depression. "The question we ask is very relevant to Singapore and in other places as well. In Singapore, the lifetime incidence of depression is eight per cent of the general population. As a comparison, in Western countries for instance, the lifetime incidence of depression is 12 per cent in men and 20 per cent in women," said Dr Zhang.
