Lamar, 36, was found unconscious at a Las Vegas brothel last month and, although he is now responsive, 31-year-old Khloe admitted he has no idea what caused his brain injury.
Appearing on The Ellen Show, Khloe said: “I can’t tell him. We tell him he had a brain injury, I can’t tell him how that brain injury was caused. It will set him back.”
Rather than reveal the truth about his alleged drink and drug binge, Khloe has vowed to stand by her estranged husband, and it was recently reported they’ve called of their divorce proceedings.
Khloe told Ellen Degeneres: “He is off all the machines that help his organs but he has such a long way to go.
“He’s learning how to walk again and feed himself again and put sentences together. Cognitively there is a lot… it’s a long, long road ahead.”
And Khloe, who filed for divorce from Lamar in December 2013 after four years of marriage, revealed the basketball player is still struggling to remember basic things such as his age.
She said: “He couldn’t put words together today. But he understands. He’s really confused, a lot we have to remind him. Every day is different.
“Sometimes he knows who the president is, and his birthday, and other times he thinks he’s 26, and I say, ‘I bet you wish you were 26, so do I’.”
