PARIS — Leonardo da Vinci may have suffered traumatic nerve damage that left him with a "claw hand", impairing his ability to paint in later life, a new study said. The two scientists reached their finding by studying a chalk drawing of da Vinci attributed to the 16th-century Lombard artist Giovanni Ambrogio Figino. "Rather than depicting the typical clenched hand seen in post-stroke muscular spasticity, the picture suggests an alternative diagnosis such as ulnar palsy, commonly known as claw hand," Lazzeri said in the report. Researchers say the physical weakness of Leonardo da Vinci, whose sculpture by Italian artist Pietro Magni is seen in Milan, was not accompanied by any cognitive decline . French President Emmanuel Macron and Italian counterpart Sergio Mattarella on Thursday kicked off commemorations to mark 500 years since da Vinci died in France.
