A leukotomy refers to what is now more commonly known as a prefrontal lobotomy (Greek: leuko: white matter of brain, tomy: cutting). It consists of cutting the connections to and from, or simply destroying, the prefrontal cortex. These procedures often result in major personality changes. Leukotomies have been used in the past to "treat" a wide range of mental illnesses including schizophrenia, depression, and various anxiety disorders. They have even been used to allegedly "cure" communism, homosexuality, and even simple disruptive behavior.
For an example of the personality changes associated with damage to the frontal lobe not related to a surgical leukotomy, see the famous case of Phineas Gage.
The first controlled human leukotomy was performed by the Portuguese physician and neurologist António Egas Moniz in 1936. His method involved drilling holes in patients' heads and destroying the tissue connecting the frontal lobes by injecting alcohol into them. Moniz won the Nobel Prize for medicine in 1949 for this work.
The procedure was popularized in the United States by Dr. Walter Freeman, who traveled the country performing "ice pick lobotomies," which involved pushing an ice pick-like instrument through the tear ducts to destroy brain matter. Freeman performed the operation on thousands of people.
In 1950 leukotomy was banned in the USSR. With the advent of Thorazine in the 1950s, leukotomy became more criticized, on charges of it being a kind of numbless torture destroying consciousness. Walter Freeman's services fell out of fashion, and he eventually lost his medical license when one of his patients died.
In 1977, the US Congress created a National Committee for the Protection of Human Subjects of Biomedical and Behavioral Research to investigate allegations that psychosurgery, including lobotomy techniques, was used to control minorities and restrain individual rights, and that it had unethical after-effects. It concluded that, in general, psychosurgery had positive effects. However, concerns about leukotomy steadily grew, some countries such as Germany, Japan and several US states prohibited it. Leukotomy was legally practiced in controlled and regulated US centers, and in Finland, Sweden, the United Kingdom, Spain, India, Belgium and the Netherlands. The practice had generally ceased by the early 1970s, but some countries continued small scale operations through the late 1980s. In France, 32 lobotomies were performed between 1980 and 1986 according to a IGAS report; about 15 each year in the UK, 70 in Belgium, and about 15 for the Massachusetts General Hospital of Boston.
