Since Kraepelin (1896), self-abnormalities have been regarded as the core pathological characteristics of schizophrenia. He believed that “the loss of the internal unity of the self” was like “no conductor in an orchestra”. Eugen Bleuler (1911) pointed out that the patients ego tended to experience “the most complex changes”, including self-fragmentation, loss the sense of activity or ability to guide thinking. However, the DSM-IV and ICD-10 diagnostic criteria for schizophrenia do not mention the concept of self. Since 2019, the world health organization (who) published the eleventh edition of the international classification of diseases (ICD-11), compared to ICD-10 and the DSM-IV, the diagnostic criteria for schizophrenia have added the phenomenological term- “self experience disorder”, but the description of the abundant connotation of self experience disorder remains brief, which affects the psychiatrists to understand the symptoms. This paper reviews the related contents.
