Michael Schumacher is "following" the progress of his son's rise to Formula 1.
RTL France asked the 74-year-old if he can update the world about the unknown health condition of seven time world champion Schumacher.
"This is a question on which I am going to be extremely reserved," the Frenchman answered.
"I see Michael very often - once or twice a month. My answer is the same all the time - he fights. We can only wish for him and his family that things get better."
Todt reassured Schumacher's fans, who have not seen or heard from him since late 2013, that the German is "very well cared for and in a place that is very comfortable".
"Of course he is following him," Todt answered.
"Mick is probably going to race in Formula 1 next year which will be a great challenge. We would be delighted to have a new Schumacher at the highest level of motor racing."
