Schizophrenia, as a common mental disease, seriously threatens the physical and mental health of human beings. It is characterized by many mental and behavioral disorders, such as uncoordinated thinking and emotional mode which separated from the actual living environment. Patients with schizophrenia are prone to relapse and deterioration due to their long course of disease, resulting in the loss of labor force. It has been proved that the occurrence and development of schizophrenia is closely related to the abnormal development of oligodendrocytes, which have the function of myelin formation and the dysfunction of myelin sheath itself. For a comprehensive understanding of myelin abnormal effects on the pathogenesis of schizophrenia, this paper is to review the literature, then summarize and discuss the animal experimental literature related to the abnormal myelin sheath in schizophrenia from the perspectives of behavioristics, neuroimaging, protein expression and stereology, in order to further clarify the influence of the abnormal myelin sheath on the pathogenesis of schizophrenia and provide ideas for the diagnosis of schizophrenia and the research and development of new drugs.
