The idea to use ECT in humans first came to Cerletti from watching
pigs being
anesthetised with electroshock before being butchered. The story goes, that on his way home he stopped at a butcher shop. The shop didn't have the cut of meat that he wanted and he was told to walk back to the slaughter house behind the shop to have the cut made for him. At that slaughter house, the technique used for butchering cattle involved an electric shock to their heads. This would cause the cattle to go into seizures and fall down, making it easy to slit their throats. In that time period, people believed that seizures were essential in preventing schizophrenia, since many believed that those diagnosed with epilepsy were immune to the disorder. Cerletti reasoned that electric shock might be useful in humans as a treatment for schizophrenia. Furthermore, since 1935,
metrazol, a
convulsant drug, and
insulin, a hormone, were in wide use in many countries to treat
schizophrenics, with great success. This approach was based on Nobel winner
Julius Wagner-Jauregg's research on the use of
malaria-induced convulsions to treat some nervous and mental disorders, such as the
general paresis of the insane, caused by neural
syphilis, as well as on
Ladislas J. Meduna's theory that schizophrenia and epilepsy were antagonistic. The pharmacological convulsive treatment of
Ladislas J. Meduna would eventually be largely replaced by the less cumbersome electrical method of Cerletti. Cerletti came to the use of electroshock for therapeutic purposes in humans by way of many experiments with animals on the neuropathological consequences of repeated
epileptic seizures. In Genoa, he used electric current to provoke repeatable, seizures in dogs and other animals. In these early experiments, many of the animals that were used ended up dying. In Rome, his assistant Lucio Bini realized a rudimental apparatus with a control panel that could safely be applied to humans. Cerletti first used ECT in a human patient, a diagnosed schizophrenic with
delusions,
hallucinations and confusion, in April 1938, in collaboration with
Lucio Bini. A series of electroshocks were able to return the patient to a normal state of mind. This experiment indicated that electric shock treatment may hold potential to improve the condition of patients diagnosed with specific diseases. Electric shock treatment quickly replaced insulin and Metrazol as the favourite form of shock treatment. Thereafter, in the succeeding years, Cerletti and his coworkers experimented with thousands of electroshocks in hundreds of animals and patients, and were able to determine its usefulness and safety in clinical practice, with several indications, such as in acute schizophrenia,
manic-depressive illness, major
depression episodes, etc. His work was very influential, and ECT quickly spread out as a therapeutic procedure all over the world. Despite the fact that it does evoke a grand mal seizure marked by a stereotyped succession of events. Cerletti was noted to be the first person to deliver a stress treatment in which the patient did not suffer any discomfort. As a result of his experiments, which took him from the psychiatric hospital to the abattoir and the zoologic gardens, Cerletti developed a theory that ECT caused the brain to produce vitalising substances, which he called "agro-agonines" (from the Greek for extreme struggle). He put his theory into practice by injecting patients with a suspension of electroshocked pig brain. Although electroshocked pig brain therapy was used by a few psychiatrists in Italy, France and Brazil it did not become as popular as ECT, which soon replaced metrazol therapy all over the world because it was cheaper, less frightening and more convenient. Cerletti and Bini were nominated for a
Nobel Prize for Physiology or Medicine for their work on the treatment in the 1930s. Today, ECT is most often recommended for use as a treatment for severe depression that has not responded to other treatment. It is occasionally also used in the treatment of mania and catatonia. ==Legacy==
