Surgeon: Cabanas may take years to recover
"He's already seen himself in a mirror and he didn't ask any questions, he just stayed there looking without showing any reaction," Dr Ernesto Martinez told a news conference.
"The neurological recuperation can take one, two or three years, we can't say precisely."
The doctor added that Cabanas, who left hospital on Tuesday to enter a rehabilitation centre, was still not conscious of what happened to him on January 25 when he was shot in the head in a Mexico City nightclub.
The bullet is still lodged in the 29-year-old's brain.
Police are still searching for a suspect over the shooting. Some media reports say it occurred during an argument over his Mexican club America's results and Cabanas's performances.
Cabanas played a key role as Paraguay qualified for the World Cup in South Africa.
Paraguay are to meet holders Italy, Slovakia and New Zealand in Group F in June.
