The diagnosis of depression often recommends consulting with a psychiatry or psychology department for confirmation. Clinically, depression is categorized as a mental and psychological disorder, primarily characterized by low mood, slow thinking, and reduced willpower. Patients usually lack interest and pleasure, feel fatigued, self-blame, valuelessness, incapability, have low self-esteem, and poor concentration. They often feel that life is meaningless, harboring thoughts or behaviors of self-harm and suicide. They view the future as bleak, sad, helpless, and hopeless. Patients generally exhibit poor eating and sleeping habits, and there is a noticeable decline in sexual function. Therefore, in clinical settings, if the aforementioned symptoms persist for over two weeks and interfere with work, study, daily life, social, and occupational functions, a clear diagnosis is required to develop a treatment plan involving medication, psychotherapy, and physical therapy.
