Antonio Egas Moniz: A Groundbreaking Neurologist

Angiography
- Developed the angiogram (brain blood vessel X-ray).
- Invented the angiogram while a neurologist at the University of Lisbon.
- Used 25% sodium iodine solution for clear results.
- Became a standard diagnostic tool for blocked arteries until the development of CT imaging in 1975.
Psychosurgery:
- Believed that operating on the frontal lobes could alleviate mental illnesses like depression and obsession.
- Developed the leucotome (a needle with a wire loop) for cutting through frontal lobe tissue.
- The leucotome was a less radical approach than removing the tissue.
- Refined in the United States, becoming a common treatment for mental illness until the 1960s.
- Only about a third of patients benefited, and many experienced negative side effects.

Moniz's Milestones
