Jules Bianchi’s family has revealed the extent of the head injuries he suffered in a crash during the Japanese Grand Prix.

While the 25-year-old Frenchman remains in intensive care at the Mie General Medical Center in Yokkaichi in a critical but stable condition, it has been confirmed that he has suffered a diffuse axonal injury.

Such an injury is usually the consequence of the forces of a rapid acceleration or deceleration of the head and affects the nerves in the brain.

Its severity can vary over a wide range.

“This is a very difficult time for our family, but the messages of support and affection for Jules from all over the world have been a source of great comfort to us,” said Bianchi’s family in a statement.

“We would like to express our sincere appreciation.

“The hospital will continue to monitor and treat Jules and further medical updates will be provided when appropriate.”

The family thanked FIA Medical Commission president Professor Gerard Saillant for his presence at the hospital, and also Professor Alessandro Frati, neurosurgeon of the University of Rome La Sapienza, who has travelled to Japan at Ferrari’s request.

“They arrived at the hospital today and met with the medical personnel responsible for Jules’ treatment, in order to be fully informed of his clinical status so that they are able to advise the family,” the statement added.

“Professors Saillant and Frati acknowledge the excellent care being provided by the Mie General Medical Center and would like to thank their Japanese colleagues.”
