He was diagnosed at the age of 10. He said of his learning difficulty, "I did not understand what was happening. I was constantly forced to try to achieve the same levels as others. That takes a lot of time and leaves you frustrated because you can't do it." He also said that he used sports, especially rugby, as an outlet for his frustration. Prince Louis lives in Paris and works as a consultant for Laurent Meeschaert Conseil. 

Marriage and Family 

On 12 March 2006, Tessy Antony gave birth to a boy, named Gabriel Michael Ronny de Nassa, who was born at a private Swiss hospital, Clinic des Grangettes, in Geneva. Their son was the first grandchild of Grand Duke Henri and Grand Duchess Maria Teresa.
