The goal of the study is to investigate whether adding different doses of sulforaphane will benefit the clinical symptoms and cognitive function in individuals who have schizophrenia. This study will compare the sulforaphane with placebo. There is a thirty percent change (less than half) of receiving the placebo. The purpose of including placebo is to judge if the outcome is related to the study medication rather than other reasons.

The mental health institute at the Second Xiangya Hospital, Central South University. Individuals who participate in the study will be followed for 24 weeks.
