Update 3, My Brother
He's still in ICU, but he's stable. They took him down a bit ago for a CT scan. They are switching his medication for his brain swelling to see if they can get that down. He's responsive to commands, and knows who everyone is, and knows where he is at. The doctors are giving him a good prognosis, and say that his sleeping and such are normal for his head inguries. BUT... He'll be fine, and make it through. It's just going to be a tuff, and long healing process for him. The doctors say he's improving. I'll let you know if they find anything on the CT scan.
Update: The CT scan came back ok. The doctors still say he's doing well.
