psychiatrist Ladislas J. Meduna (1896–1964), also known as the discoverer of one of the forms of shock therapy, using the drug metrazol. Although oneirophrenia was recognized as a specific condition in the 1950s, it was not studied in depth until the 1960s. During its beginning stages oneirophrenia was studied very closely with schizophrenia as an acute form due to the relationship between their symptoms. It wasn't until greater research that oneirophrenia became its own mental disease. References Neurological disorders Obsolete terms for mental disorders
