For controlling and treating the mood problems of depressed patients, there are mainly medication methods, psychotherapy methods, and self-adjustment methods. The main method of medication is the use of common antidepressants, such as sertraline, fluoxetine, or agomelatine, bupropion and other drugs for treatment, which usually need to be taken for about 4-6 weeks to have a significant effect. After the effect, it needs to be maintained and consolidated for about 6 months before the disease can be completely controlled and reach the state of clinical cure. Psychotherapy mainly includes cognitive-behavioral therapy, Morita therapy, and humanistic therapy, etc. These methods rely on the patient to establish a good relationship with the psychotherapist, to understand themselves through the help of the psychotherapist, to improve distorted beliefs, to make new mental constructs, and to engage in good behavior in order to slowly alleviate depression and other emotional problems. For self-adjustment, it is possible to alleviate depression mainly by engaging in more healthy behaviors, such as going to bed early, waking up early, exercising appropriately, and communicating and engaging with friends more often. If none of the above methods work, or if you already have serious suicidal problems or food refusal problems, you can also consider physical therapy methods, commonly used are electroconvulsive treatment methods and transcranial magnetic stimulation treatment methods, all of the above methods are available, be sure to choose the right method for you.
