Warmbier is in stable condition at UC Medical Center, where he was taken Tuesday night after his arrival in Ohio. Dr. Daniel Kanter, director of the Neurocritical Care Program, said that his patient had not "engaged in any purposeful movements" and "shows no signs of understanding language or responding to verbal commands".
Doctors with the University of Cincinnati Health system say Warmbier shows extensive loss of brain tissue, consistent with respiratory arrest, when the brain is cut off from oxygen but they aren't sure why.
Doctors found no evidence of trauma after examining all of the bones in Warmbier's body. "North Korea doesn't do anything out of the kindness of their heart".
Such injuries, doctors say, usually come about as a result of inadequate blood supply to the brain. "In those scans we see no evidence of an acute, or healing fracture of the skull". He also praised the Trump Administration's assistance in bringing his son home.
The US student released by North Korea this week has damage to all parts of his brain, doctors said Thursday. "No other family should have to endure what the Warmbiers have". He said they traveled to Washington and met with Ambassador Yun who more aggressively pursued Otto's release.
"The burden of our ordeal has been eased by the support we have experienced, not only from our friends in Cincinnati, but through OH, at the University of Virginia, throughout the United States and, indeed, from around the world", Warmbier said.

Otto was detained in North Korea on January 2, 2016 at the Pyongyang International Airport after visiting that country with Young Pioneer Tours. After making a tearful confession before the cameras, he was sentenced to 15 years' hard labor.
"I knelt down by his side, and I hugged him, and I told him I missed him and I was so glad that he made it home", Fred Warmbier said.
The father of the University of Virginia student who was released from North Korea this week said US basketball Hall-of-Famer Dennis Rodman's visit to Pyongyang had no connection to the freeing of Otto Warmbier.
Otto Warmbier, a University of Virginia student, was medically evacuated from North Korea and flown to Cincinnati late Tuesday. Here's Fred Warmbier's full statement. They plan to hold a news conference Thursday morning in their home state of Ohio.
Former New Mexico Gov. Bill Richardson, a former USA ambassador to the United Nations who has negotiated with the North Korean regime in the past, said there should be an investigation into what happened to Warmbier leading to this "tragic situation".
Warmbier said even if the North Korean story was true, there's still no excuse for keeping a 15-month coma a secret until last week and denying him access to top-notch medical care.
"He doesn't deserve this", Fred Warmbier told The Cincinnati Enquirer in an interview last month.
