Doctors who have worked extensively with Lamar Odom fear that he could be suffering from severe brain damage.

Odom has been hospitalized since October 13 as he tries to recover from a drug overdose, and according to a TMZ report, loved ones say Odom can’t recognize close friends and family.

In addition to problems with basic communication and motor skills, the former NBA player has seemed “empty.”

More from TMZ:

Lamar Odom’s in rough shape — having a tough time with communication and mobility — and we’re told it’s so bad, he can’t recognize some close friends and family.

 

Our sources tell us Lamar has made little progression in the last couple weeks. We’re told he’s only able to speak a word here and there, and at times he seems “empty.”

 

The scariest part … Lamar can’t recognize longtime friends and even family members when they come to visit. We’re told docs believe he’s suffered significant brain damage.
