Lamar Odom 'Not Doing Great,' Sometimes Forgets His Own Name, Source Says

"His speech is still slurred and he can barely walk on his own yet."

Lamar Odom's road to recovery is definitely going to be a long one.

Although Khloe Kardashian said last month that the 36-year-old former NBA star could be "mentally fully recovered" in a year and a half, a source close to Lamar tells ET that, currently, he's far from looking like his old self.

"He's not doing great," the source says. "His speech is still slurred and he can barely walk on his own yet. He forgets a lot of people's names -- sometimes even his own. He definitely has some memory loss."

But on the bright side, the Kardashian family is still fully supporting him.

"They all pop in to see him [at Ceders-Sinai Medical Center], including Khloe," the source says.

The Insider
caught up with 31-year-old Khloe last month while she was promoting her book, Strong Looks Better Naked, when she admitted that her ex was still having trouble processing the events of the last two months. Odom was found unresponsive at the Love Ranch brothel in Crystal, Nevada on Oct. 13, and has since been undergoing intense therapy after coming out of a coma.

"I don't know if he can right now," Khloe candidly responded when asked if Lamar has been able to show her gratitude for sticking close to his side. "Like, I don't know if he fully understands everything, but I know he is grateful... and I'm not doing it for validation. I'm not doing it to get praise back."

"He’s doing better every day, for sure, which is a blessing, but it's going to be a long road and he has to walk that road," Khloe also stressed to ET last month. "It's going to be a long time."

In a new video on her website and app on Sunday, Khloe talked about her struggles with anxiety after going through a rocky 2015. Last month, Khloe said she was suffering from a staph infection that was exacerbated by stress, and also had to cancel her book tour.

"Lord knows I've had stress and anxiety lately," she said. "This year has been absolutely horrible, but it's almost done. I'm just praying that 2016 will be better. It has to be."
