The Legacy of Egas Moniz: Triumphs and Controversies in Medical Innovation

António Egas Moniz, a pioneering Portuguese neurologist, is renowned for developing cerebral angiography and introducing the prefrontal leucotomy (lobotomy), for which he received the Nobel Prize in 1949. Initially hailed as a breakthrough for conditions like schizophrenia and severe anxiety, lobotomy later became controversial due to severe side effects, including irreversible personality changes. The advent of neuroleptics, such as chlorpromazine, in 1952 led to the decline of lobotomy in favor of more effective and humane treatments. Moniz's work raised significant ethical concerns, particularly regarding informed consent and the procedure's long-term impact, underscoring the need for continuous advancement and ethical considerations in psychiatric care. We present a narrative review of Egas Moniz's life and his pioneering discovery of cerebral angiography, which had a significant impact and a lasting legacy in neurology. Additionally, we highlight the evolution of alternative brain surgeries that arose from modifications of his original prefrontal leucotomy.
