Smiling depression is a psychological disorder that is a manifestation of depression with atypical symptoms that can be accompanied by weight loss, weight gain or hyperphagia.
Smiling depression patients often deny that they have a low mood or sadness, and also produce positive reactions such as smiling when something good happens, but there is still supporting evidence of a depressive episode through other reactions of the organism, such as weight change, insomnia, and slow thinking.
Smiling depression mostly occurs in high-income, highly educated and stressful people, and its onset has a certain correlation with the patient’s family, personality, living environment and other factors.
People suspected of having smile-type depression should receive timely psychotherapy to avoid serious adverse consequences such as suicidal tendencies.
