Leonardo da Vinci's Procrastination Linked to ADHD and Creativity

A study by Marco Catani from 2019 suggests that Leonardo da Vinci might have had ADHD. Catani's research indicates that Leonardo was often very active and would frequently switch between tasks, a habit that started in his early years. This tendency to delay might have actually fueled his creativity. In Walter Isaacson's biography, it’s noted that while working on The Last Supper, Leonardo sometimes spent an entire hour just thinking about a small detail. He left several works unfinished, including the Mona Lisa, which he touched on from 1503 until his death in 1519. His patrons, like Pope Leo X, often grew impatient with his methods. The piece concludes with Aaron Haspel's quote about our shared psychological struggles.
