The hospital treating Alex Zanardi says his neurological picture “remains serious” and are still unable to provide a full prognosis into his condition.
Zanardi was involved in a road accident on his native Italy on Friday afternoon in which his handcycle struck an oncoming truck.
Zanardi was airlifted to Siena’s University Hospital and underwent neurosurgery and maxillofacial surgery due to the severe head trauma, before being transferred to the Intensive Care Unit.
In the latest update, issued on Sunday morning, the hospital explained that Zanardi “spent the night in conditions of cardio-respiratory and metabolic stability. The organ functions are adequate.
“He is always sedated, intubated and mechanically ventilated.
“The ongoing neuromonitoring has shown some stability but this figure must be taken with caution because the neurological picture remains serious.
“The current conditions of general stability still do not allow to exclude the possibility of adverse events and, therefore, the patient always remains in a reserved prognosis.”
Zanardi, who started 41 Formula 1 grands prix and won two CART titles in the 1990s, has participated in handcycling following the accident in 2001 that resulted in the amputation of his lower legs.
He won four gold medals, and two silvers, across the last two Paralympic Games in London and Rio.
