Mild depression is primarily treated clinically through self-adjustment, psychotherapy, or physical therapy. Self-adjustment often involves exercise, which can stimulate the brain to release endorphins, playing an anti-depressive role. Additionally, exercise is an effective relaxation training that can divert attention and stimulate feelings of control and pleasure. Furthermore, psychotherapy is also used in clinical settings, particularly cognitive behavioral therapy, which is crucial in helping patients identify thoughts, correct irrational cognitive patterns, and rebuild their cognitive systems. Effective training in social and other activities is also necessary to enhance social or occupational functioning. In terms of physical therapy, repetitive Transcranial Magnetic Stimulation (rTMS) is the main treatment method.
