The expert committee’s report about a new standard of employment injuries authorization of mental disorders for the use of the Industrial Accident Compensation Insurance Act was shown on the website of the Ministry of Health, Labour and Welfare, Japan on November 8th,2011.Unfortunately,a significant number of patients with mental disorders do not achieve a fully symptom-free recovery, and display residual symptoms and lower levels of social and psychological functioning. Definitions of recovery from mental disorders can vary, and it is difficult to decide on the boundary between reversible and irreversible medical conditions. Psychiatrists should prepare diagnosis guidelines for when the medical condition is viewed as non-changing（symptom fixation）for work-related mental disorders after treatments are given for a period deemed long enough for a return（or not）to premorbid psychosocial functioning.
