There are 2 clinically important and urgent questions to be explored in this study: 1. Who is more likely to benefit from guided drug reduction or discontinuation? How to design an individualized treatment plan which can balance the risk of relapse and side-effects from antipsychotics? 2. What are the predictors of functional remission in patients with schizophrenia after drug discontinuation? This will be the first related study to be conducted in China.
