Lamar Odom is slowly but surely continuing his recovery.
During her interview with the Today show on Thursday, Khloe Kardashian said doctors think the 36-year-old former NBA star could be "mentally fully recovered" within two years.
"He's OK. Every day is different," Khloe said. "The good thing is he's off of medical machines that will keep him alive. He's learning how to walk again, and [continuing] cognitive therapy and speech therapy. They think, like, within a year and a half to two years, he might, you know -- mentally -- be fully recovered, but they don't know."

The 31-year-old reality star also revealed that she was told Lamar only had four hours to live after he was discovered unresponsive at the Love Ranch brothel in Crystal, Nevada, on Oct. 13.
"It's a horrible call to get," Khloe said. "Getting to the hospital and knowing he's in a coma and having to run these tests or make medical decisions. It's terrifying."
"You have to make risk-and-reward decisions," she continued. "Like, OK, well, there's an 80 percent chance if we do this operation, he might pass away. But also if we don't do it, there's a 90 percent chance he'll pass away. ... It was probably one of the most emotionally stressful times ever in my life."
As for the status of their divorce -- which the two called off last month -- she revealed that she's still, in fact, "separated" from him.
"I was expediting the divorce prior, and I'm still separated with him, but I'm just not expediting them anymore," she clarified. "There was no reason for it. And also, [it's] in his will that I'm always the medical adviser. And it was just -- he had no one else to make these decisions for him."
Khloe is still dating 26-year-old NBA pro James Harden. On Wednesday, Khloe went on a Twitter rant against some who called her out after she congratulated the Houston Rockets on their "dope ass game."
When a few of her Twitter followers responded with, "You can't be with Harden and still be married fam, gotta chose one," and "For better or worse sickness and health till death do them part. I'm with you she needs to pick one or the other," Khloe didn't hold back.
"You should have said those to the man who went against all our vows. Judge yourself. F**k off," she responded.
To one user who accused her of being with Lamar to "look good in the media," she fired back, "Ummmmm how does that look good in the media? He wasn't picking roses my friend. Get off my d**k."
Later, she blamed her fiery responses on her medication.
"Signing off.... Antibiotics +painkillers + tweeting does not equal anything good lol," she tweeted.

Khloe's recent comments on Lamar's improving health is a big turnaround from what she told The Insider earlier this month, when she said he didn't think he was capable of showing her gratitude for sticking by his side.
"Like, I don't know if he fully understands everything, but I know he is grateful," Khloe said. "And I'm not doing it for validation. I'm not doing it to get praise back."
