Brief summary
Investigators plan to explore whether Omega-3 fatty acid have effect on the violent behavior of the schizophrenia patients. Investigators will use PET to explore the influence on serotonin function of the brain to understand the mechanism of how Omega-3 fatty acid works. This study will enroll 100 patients of schizophrenia with violent behavior.Participants will be split into two groups randomly. In one group, participants will receive one pill of placebo per day, and in the other, participants will have one pill of 900mg Omega-3 fatty acid per day. This intervention will last 3 months.At week 0, week 4, week 8 and week 12, some scales will be evaluated. Meanwhile, the density of eicosapentaenoic acid(EPA),docosahexaenoic acid (DHA),noradrenalin(NE), dopamine(DA) and serotonin(5-HT) in blood will be tested.At week 0 and week 12, 10 patients of each group will be randomly selected to have the exam of PET.
