Decline in the severity or the incidence of schizophrenia in Japan: A survey of university students.

Clinical manifestations of schizophrenia are believed to be becoming less severe in Japan, but little evidence supports this theory. We investigated the percentages of undergraduate students attending national universities in Japan who required temporary leave and who dropped out because of schizophrenia in the academic years 1986-1987, 1994-1995, and 2013-2014. The percentages of students who required temporary leave and those who dropped out because of schizophrenia significantly decreased over time.
