Warmbier can open his eyes and blink but has no signs of understanding language or responding to commands, Kanter said.
At a news conference Thursday morning in his home state of Ohio, Otto Warmbier's father, Fred Warmbier, said there's "no excuse" for North Korea's treatment of his son.
But they could not definitively say what could have caused such an event, saying they had found no signs of a botulism infection - the explanation given by the North Korean regime for how the young man fell into a coma. Doctors treating him in the US said they found no evidence of botulism, but did find severe brain damage consistent with losing oxygen to the brain. He said there was no reason for North Korea to keep his 22-year-old son's condition a secret and deny him top medical care.
He has been in a coma for more than a year, since shortly after his last public appearance at his trial in March of 2016, the Washington Postreported.
His family said he arrived in a state of coma.
Warmbier was released from a North Korean prison and returned home to suburban Cincinnati on Tuesday in a coma.
Doctors said they examined Warmbier's body and saw no evidence of fractures that might be evidence of severe beatings. Fred Warmbier said at a news conference Thursday that Trump had said he was "sorry" and criticized his predecessor Barack Obama for his failure to obtain Otto Warmbier's release earlier.
More than any words that would be used to describe Warmbier's condition in clinical terms by doctors and government officials, Woolston's photographs told the stark story of his medical state with profound impact.
Earlier Thursday, a hospital spokeswoman said Warmbier suffered a "severe neurological injury" while in North Korean custody.
His father, Fred Warmbier, said the family was proud of him, calling him "a fighter".
The doctors said they are not aware of anything from his previous medical history, prior to his time in North Korea, that might cause cardiopulmonary arrest.
CNN reports that at a meeting on June 6 in New York, North Korea's United Nations ambassador told the State Department's special representative for North Korean policy, Joseph Yun, that Otto was in a coma. His parents said that they were only informed of their son's condition a week before the release.
There had been speculation as to whether Warmbier's release had anything to do with basketball star Dennis Rodman's recent trip to North Korea.
