Mild depression can achieve good therapeutic effects. Patients with mild depression may experience low mood, slow thinking, and decreased volition, but its severity is relatively mild. These patients primarily show lack of concentration, or slightly lower self-evaluation, and abnormalities in diet and sleep. Generally, the overall mental state of the patients is still relatively good. Therefore, in clinical practice, the main treatment for patients with mild depression is psychotherapy, especially cognitive behavioral therapy, to improve the patients' distorted and unreasonable cognition, ultimately leading to cognitive reconstruction and achieving good therapeutic effects. Antidepressant drugs can also be used for systematic treatment, such as serotonin reuptake inhibitors, which have an effective cure rate of over 85%.
