Lamar Odom reportedly suffered a dozen strokes early on during his hospitalization, and it's affecting both his ability to both walk and talk.

Doctors discovered the strokes after performing a series of brain scans, according to TMZ. Odom will reportedly have to undergo months of physical therapy, but even then, doctors aren't sure whether he will make a full recovery. Odom underwent two emergency surgeries on Thursday, and he remains on dialysis.

Odom’s estranged wife Khloe Kardashian has remained by his side since he was hospitalized on Tuesday, October 13. “She sleeps in the ICU with him,” a source told Us Weekly. A second source added, “Khloe’s not really responding to friends who’ve reached out; I think she’s just in a bubble with her family right now.”

Doctors have banned all visitors except Khloe, who recently called off the couple's divorce. “[Khloe] loves him so much, and she takes their wedding vows — for better or worse, in sickness and health — extremely seriously. This is a huge wake up call for Lamar, for his friends and family. Everyone is just really hoping for the best," another source told the mag.
