His breathing is agonal - which means he is having a hard time breathing on his own. It looks a lot like a hiccup everytime he takes a breath. The neurologist's concern there is that Garren's brain has been damaged to a point that it is unable to control his respiratory functions properly.
Also, he is showing possible signs of diabetes incipitous. Basically, he is passing more urine than he should be. This is controlled by the pituitary gland, which is located in his brain as well.
I asked if the swelling on his brain could be responsible for some of these symptoms. The doctor very carefully answered, not wanting to give false hope, that it is a possibility, but we can't say for sure.
They will test his urine for the diabetes issue, and then we should be able to know a little more.
