Meduna's interest in treating schizophrenia began with observations that the concentration of brain glia varied among patients who died with epilepsy (more glia than normal) and those with schizophrenia (less glia than normal). He thought that the inductions of seizures in patients with schizophrenia would increase the concentration of glia and relieve the illness. The concept was supported by reports that the incidence of epilepsy in hospitalized patients with schizophrenia was extremely low; and that a few schizophrenic patients who developed seizures after infection or head trauma, were relieved of their psychosis.

He sought ways to induce seizures in animals with chemicals; after trials with the alkaloids strychnine

 dissolved in oil as effective and reliable. For a population with severe schizophrenia, he moved from Budapest to the psychiatric hospital at Lipotmező, outside Budapest. He began his dose-finding experiments on January 2, 1934. He was able to induce seizures in about 1/3 the first subjects. Nevertheless, three of the first 11 patients had a positive response, encouraging his work.[See Gazdag et al., 2009.] In his autobiography, he recalls the patient who began his treatment on January 23, 1934 in a severe 33-year-old catatonic

A major factor in Meduna's achievement was his selection of patients—9 of the first 11 patients were catatonic. Catatonia

 is a syndrome that is remarkably responsive to induced seizures. The serendipity that catatonia was considered schizophrenia made his discovery possible.

Early in his work Meduna replaced camphor with pentylenetetrazol (Metrazol), an intravenous agent that induced seizures immediately compared with the long delay of 15 to 45 minutes after intramuscular camphor.

He first published his results in 1935 and then his major text in 1937. Die Konvulsionstherapie der Schizophrenie describes the results in 110 patients. Of these patients about half recovered. The results were much better for patients who were ill less than a year compared to those who had been ill for many years.

His results were quickly reproduced in many other centers around the world and this form of therapy became widely used and recognized as the first effective treatment for schizophrenia. (A parallel development was insulin coma therapy.) A more facile form of induction of seizures, using electricity instead of chemicals, was developed by the Italian psychiatrists Ugo Cerletti
