Brief Summary

At present, the treatment of Bipolar I disorder (BD-I), especially its depressive episode (bipolar depression), is still limited, because there is no effective treatment for the associated cognitive impairment and perceived stress. NMDA receptor (NMDAR) dysfunction is associated with BD-I, particularly its cognitive impairment and perceived stress. This study aims to examine the efficacy and safety of an NMDA enhancer (NMDAE) in the treatment of cognitive impairment and perceived stress in the patients with bipolar depression.
