Omega-3 Unsaturated Fatty Acid Improves Cognitive Function in Patients With Depression

Guangzhou Psychiatric Hospital288 enrolled

Overview

The aim of this study was to evaluate the effect of n-3pufas on cognitive function in patients with depression

Depression is often accompanied by cognitive impairment. At present, there is no effective drug to improve the cognitive impairment in patients with depression, and the social function and quality of life of patients are affected in varying degrees. N-3 polyunsaturated fatty acids (n-3pufas) are food products with high safety and few adverse reactions. Previous clinical trials have also suggested that n-3pufas may help to improve cognitive impairment in patients with depression, but the reported results are different. We have developed a new generation of n-3pufas optimal proportion combination products and found good cognitive improvement effect in animal models of depression. Therefore, this clinical research project will screen out the depressive patients with cognitive impairment through the cognitive function battery test (MCCB) tool for schizophrenia. On the basis of routine treatment of depression, these patients will be added with the cognitive improvement formula n-3pufas capsule developed by us to explore the effect of n-3pufas formula on cognitive impairment of depression.
