Brief Summary

Bipolar disorder has a high hospitalization rate, suicide rate and disability rate, and cognitive dysfunction is one of the core clinical symptoms of bipolar disorder. Cognitive recovery has become a new target and a new target for clinical treatment. In recent years, gut microbiome has been recognized as one of the neuropathological mechanisms of bipolar disorder. This study aims to study the effect of probiotics on cognitive function in stable bipolar disorder patients and the possible mechanism of action. A total of 100 patients with stable bipolar disorder were enrolled into the control group and the experimental group in a random double-blind way to evaluate the intestinal microecology, clinical symptom improvement, cognitive function and side effects before and after treatment between the two groups, and further explore the possible mechanism of action of the experimental drug.
