António Egas Moniz: From pioneering brain imaging to controversial psychosurgery. A 150th birthday celebration

António Egas Moniz, born in 1874, was a pioneer in neurology, neurosurgery and psychiatry who brought about important changes in the 1920s using groundbreaking brain imaging techniques, such as cerebral angiography. This innovative procedure allowed the visualization of brain structures, leading to many advances in neurology and neurosurgery. Moniz also made noteworthy contributions to psychosurgery, including the development of prefrontal lobotomy. Although initially praised for his inventive techniques, lobotomy sparked ethical debates and public controversies due to its adverse effects and questionable scientific foundation. Moniz's was awarded the Nobel Prize in Physiology or Medicine in 1949 and received various honors in Portugal for his scientific, literary, and artistic achievements. His work continues to influence the field of neuroscience, and angiography remains a crucial imaging method for diagnosing and treating brain disorders. Moniz's complex legacy highlights the intricate balance between medical advances, ethical considerations, and public perceptions in the history of medicine.
