Study Notes
António Egas Moniz
- Highly regarded neurologist, known for groundbreaking brain imaging research
- Developed frontal lobotomy, a controversial surgical procedure
- Invented angiogram (X-ray technique) in 1927, aiding in identifying brain tumors
- Used iodine solution for safer visualization of brain vessels
- Used experiments on human subjects
- Pioneers psychosurgery; believed certain mental illnesses could be treated by operating on the frontal lobes of mentally ill patients
- Designed leucotome (needle with wire loop) to cut tissue of lobes, aiming to alleviate depression, anxiety, and schizophrenia
- Technique became standard until 1960s
- Procedure had limited success (only 1/3 of patients benefitted, others suffered harm)
