Study Notes
António Egas Moniz
- Highly regarded for brain imaging research
- Developed the controversial frontal lobotomy technique
- His work was instrumental in psychiatric treatment during the 1940s and 1950s
- Invented the angiogram, a type of X-ray for checking blood vessels
- Used injections of radiopaque dyes to locate brain tumors effectively
- Pioneered psychosurgery, attempting to cure mental illness through frontal lobe operations
- Developed a leucotome (needle with a wire loop) for cutting frontal lobe tissue
Lobotomy Technique
- Aimed to cure mental states like obsession, depression, anxiety, etc., by altering associated personality traits and behaviors
- Used a needle with a wire loop (leucotome) to cut connections in the frontal lobes
- A standard procedure in the US until the 1960s
Diagnostic Tools
- Moniz's angiogram aided in precise location of brain tumors
- Angiograms were the only effective way to image cerebral blood vessels before CT imaging
Moniz's Life
- His life was described as unusually productive
- His name will live on for two significant contributions
- Awarded the Nobel Prize in Physiology or Medicine in 1949 for the invention of the prefrontal lobotomy
