NCT00621998

Brief Summary

We initiate a study with research grant from department of health and Taoyuan mental hospital and choose risperidone and olanzapine as study medications. We compare the effects of these 2 drugs in schizophrenic spectrum patients of Han ethnics with neuroleptic-induced tardive dyskinesia to test the hypothesis that these two medications have different effects in improving tardive dyskinesia.
