Italian scientist Rita Levi-Montalcini - First Nobel Prize-winner to reach the age of 100




"She was awarded the 1986 Nobel Prize for Medicine jointly with an American, Stanley Cohen, for her research into NGF: the proteins and amino-acids which enable the cells of the nervous system to grow and take on specialised tasks. Despite her age, Dr Levi-Montalcini, a neurologist and development biologist, still works every day at the European Brain Research Institute, which she founded in Rome.

...she claimed that her brain was more vigorous today than it was four decades ago. "If I'm not mistaken," she said, "I can say my mental capacity is greater than when I was 20 because it has been enriched by so many experiences, in the same way that my curiosity and desire to be close to those who suffer has not diminished."

According to Pietro Calissano, who collaborated with the professor on an article for Scientific American in which she announced her discovery in 1979, NGF may have played a direct role in her amazing vitality. "Every day, she takes NGF in the form of eye drops," he said, "but I can't say for sure if this is her secret. At the start, it seemed this molecule's effect was restricted to acting on the peripheral nervous system, but then it emerged that it has a very important role in the brain. Contrary to what was believed, the brain does not have a rigid structure but is in continuous movement, and NGF helps neurons – which we begin to lose between 10 and 15 years old – survive."
