António Egas Moniz

António Caetano de Abreu Freire Egas Moniz (29 November 1874 – 13 December 1955), known as simply Egas Moniz, was a Portuguese neurologist and the developer of cerebral angiography. He is regarded as one of the founders of modern psychosurgery, having developed the surgical procedure leucotomybetter known today as lobotomyfor which he became the first Portuguese national to receive a Nobel Prize in 1949 (shared with Walter Rudolf Hess).

He held academic positions, wrote many medical articles and also served in several legislative and diplomatic posts in the Portuguese government. In 1911, he became professor of neurology in Lisbon until his retirement in 1944.

Early life and training Moniz was born in Avanca, Estarreja, Portugal, as António Caetano de Abreu Freire de Resende. He attended Escola do Padre José Ramos and the Jesuit-run College of Saint Fidelis. Then he studied medicine at the University of Coimbra, graduating in 1899. For the next 12 years, he served as a lecturer for basic medical courses at Coimbra. In 1911, he became a neurology professor at the University of Lisbon, where he worked until his retirement in 1944.

His uncle and godfather, Father Caetano de Pina Resende Abreu e Sá Freire, convinced his family to change his surname to Egas Moniz since he was convinced that the Resende family was descended from medieval nobleman Egas Moniz o Aio.

Politics Politics was an early passion for Moniz. He supported a republican government, diverging from his family's support for the monarchy. As a student activist, he was jailed on two separate occasions for participating in demonstrations. While serving as Dean of the Medical School at the University of Lisbon, he was arrested a third time for preventing police from settling a student-run protest.

Moniz's formal political career began when he was elected to parliament in 1900. During World War I, he was appointed the Ambassador to Spain, and afterward, he became Minister for Foreign Affairs in 1917, and in 1918 led the Portuguese delegation to the Paris Peace Conference.

Research Cerebral angiography

In 1926, at age 51, Moniz returned to medicine full-time. He hypothesized that visualizing blood vessels in the brain with radiographic means would allow for more precise localization of brain tumors. During his experiments, Moniz injected radiopaque dyes into brain arteries and took X-rays to visualize abnormalities. In his initial tests, Moniz used strontium and lithium bromide in three patients with a suspected tumor, epilepsy, and Parkinsonism, but the experiment failed and one patient died.

Moniz presented his findings at the Neurological Society in Paris and the French Academy of Medicine in 1927. He was the first person to successfully visualize the brain using radiopaque substances, as previous scientists had only visualized peripheral structures. He also contributed to the development of Thorotrast for use in the procedure and delivered many lectures and papers on the subject. His work led to the use of angiography to detect internal carotid occlusion, as well as two Nobel Prize nominations in this area.

Moniz hypothesized that surgically removing white matter fibers from the frontal lobe would improve a patient's mental illness. He enlisted his long-time staff member and neurosurgeon Pedro Almeida Lima to test the procedure on a group of 20 patients, mainly with schizophrenia, anxiety, and depression. The surgeries took place under general anesthesia. The first psychosurgery was performed in 1935 on a 63-year-old woman with depression, anxiety, paranoia, hallucinations, and insomnia. The patient experienced a rapid physical recovery, and two months later, a psychiatrist noted that she was calmer, less paranoid, and well oriented. In the first set of surgeries, Moniz reported a total of seven cures, seven improvements, and six unchanged cases. He also claimed that any behavioral and personality deterioration that may occur was outweighed by reduction in the debilitating effects of the illness. He conceded that patients who had already deteriorated from the mental illness did not benefit much. The procedure enjoyed a brief vogue, and in 1949 he received the Nobel Prize "for his discovery of the therapeutic value of leucotomy in certain psychoses."

Critics accused Moniz of understating complications, providing inadequate documentation, and not following up with patients. After his initial procedures, other physicians, such as Walter Jackson Freeman II and James W. Watts, adopted a modified technique in the United States and renamed it "lobotomy." Moniz's legacy suffered towards the end of the 20th century, Well-known experts, including psychologist Elliot Valenstein, and neurologist Oliver Sacks, were particularly critical of Moniz's methods and him earning the Nobel Prize. especially from family members of patients who underwent leucotomies. However, others have defended Moniz for his scientific contributions, stressing the need to examine his legacy in context.
